    DETAILED DESCRIPTION OF THE INVENTION

    I. Definitions

    [0087] Throughout the present specification and the accompanying claims, the words comprise, include, and have and variations thereof such as comprises, comprising, includes, including, has, and having are to be interpreted inclusively. That is, these words are intended to convey the possible inclusion of other elements or integers not specifically recited, where the context allows. The term consisting essentially of means that the composition, method, or structure may include additional ingredients, steps and/or parts, but only if the additional ingredients, steps and/or parts do not materially alter the basic and novel characteristics of the claimed composition, method, or structure. As used herein, the term consisting of is intended to mean including and limited to whatever follows the phrase consisting of. Thus, the phrase consisting of indicates that the listed elements are required or mandatory and that no other elements may be present. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention. It is understood, if not clearly contradicted by the context, that each claim claiming an embodiment of the present invention, may be crafted and presented using either (i) the transitional phrase comprising of or a grammatical equivalent thereof, (ii) the transitional phrase consisting essentially of or a grammatical equivalent thereof, or (iii) the transitional phrase consisting of or a grammatical equivalent thereof.

    [0088] The terms a and an and the and similar referents used in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context.

    [0089] The term and/or where used herein is to be taken as specific disclosure of each of the two specified features or components with or without the other. For example, A and/or B is to be taken as specific disclosure of each of (i) A, (ii) B, and (iii) A and B, just as if each is set out individually herein.

    [0090] Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. Ranges may be expressed herein as from about (or approximate) one particular value, and/or to about (or approximate) another particular value. When such a range is expressed, an embodiment includes values from the one particular value to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent about or approximate it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. With respect to endpoints of ranges, it is understood that when a range is given herein, it discloses alternative ranges, without specifically reciting them, i.e., (a) an of/from to range in which the endpoints are included in the range and (b) an between and range, in which the endpoints are excluded from the range. For example, a disclosure of a freshening composition comprising about 0.1 wt % to about 95 wt % perfume raw material includes (a) a composition comprising the perfume raw material from about 0.1 wt % to about 95 wt %, in which the endpoints 0.1 wt % and 95 wt % are included, and (b) a composition comprising the perfume raw material between about 0.1 wt % and about 95 wt %, in which the endpoints 0.1 wt % and 95 wt % are excluded. Thus, every range defined herein in the format from/of to is to be understood as also disclosing a separate and discrete range defined as between and. Likewise, every range defined herein in the format between and is to be understood as also disclosing a separate and discrete range defined as from/of to. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as about that particular value in addition to the value itself. For example, if the value 10 is disclosed, then about 10 is also disclosed. Further, the term about applies to both cited endpoints of a range, even when it is written only before the lower endpoint. For example, about X to Y should be interpreted as about X to about Y It is also understood that when a value is disclosed that is less than or equal to the value or greater than or equal to the value possible ranges between these values are also disclosed, as appropriately understood by the skilled artisan. For example, if the value 10 is disclosed the less than or equal to 10 as well as greater than or equal to 10 is also disclosed.

    [0091] In the following description it is to be understood that terms such as forward, rearward, front, back, right, left, upward, downward, horizontal, vertical, longitudinal, lateral, angular, first, second and the like are words of convenience and are not to be construed as limiting terms.

    [0092] Certain limitations of claim elements are disclosed as Markush groups. It is understood that with the disclosure of a Markush group comprising X members (wherein X is any number), a Markush group missing one or more members, i.e., a Markush group comprising X-1 members, or X-2 members, etc. is disclosed as well. For an illustrative example, where the disclosure provides a compound is selected from the group consisting of compound A, compound B, compound C, compound D, compound E, compound F, and compound G, the disclosure inherently discloses: a compound selected from the group consisting of compound B, compound C, compound D, compound E, compound F, and compound G, or a compound selected from the group consisting of compound C, compound D, compound E, compound F, and compound G, etc.

    [0093] All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. Further, all methods described herein and having more than one step can be performed by more than one person or entity. Thus, a person or an entity can perform step (a) of a method, another person or another entity can perform step (b) of the method, and a yet another person or a yet another entity can perform step (c) of the method, etc. The use of any and all examples, or exemplary language (e.g., such as) provided herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed.

    [0094] Units, prefixes, and symbols are denoted in their Systeme International de Unites (SI) accepted form. The abbreviations used herein have their conventional meaning within the mechanical, chemical, and biological arts.

    [0095] Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member may be referred to and claimed individually or in any combination with other members of the group or other elements found herein. It is anticipated that one or more members of a group may be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims.

    [0096] The headings used herein are for organizational purposes only and are not meant to be used to limit the scope of the description or the claims, which can be had by reference to the specification as a whole. Accordingly, the terms defined immediately below are more fully defined by reference to the specification in its entirety.

    [0097] Illustrations are for the purpose of describing a preferred embodiment of the invention and are not intended to limit the invention thereto.

    [0098] Unless defined otherwise, all technical and scientific terms used herein have the meaning commonly understood by a person skilled in the art to which this invention belongs. The following references provide one of skill with a general definition of many of the terms used in this invention: The Cambridge Dictionary of Science and Technology (Walker ed., 1988); Common fragrance and flavor materials: Surburg, H. and Panten, J., Preparation, properties and uses (6.sup.th ed., Wiley-VCH, (2016), ISBN: 978-3-527-33160-4), a standard industry reference on major fragrance and flavor ingredients, including both natural and synthetic materials; Turin, L. and Sanchez, T., Perfumes: The Guide, (Perfumista Publishing, 2028, ISBN: 978-0-99884501-2). Obvious typos of a word or term in this application are to be construed as the word or term as included therein or in a standard dictionary. As used herein, the following terms have the meanings ascribed to them unless specified otherwise.

    [0099] As used herein, the terms about or approximately refer to a range of values of plus or minus 20%, preferably, plus or minus 10%, more preferably, plus or minus 5% of a specified value, and more preferably, plus or minus 4% of a specified value, plus or minus 3% of a specified value, plus or minus 2% of a specified value, plus or minus 1% of a specified value, and/or plus or minus 0% of a specified value.

Thus, the term arylalkyl is meant to include those radicals in which an aryl group is attached to an alkyl group (e.g., benzyl, phenethyl, pyridylmethyl and the like) including those alkyl groups in which a carbon atom (e.g., a methylene group) has been replaced by, for example, an oxygen atom (e.g., phenoxymethyl, 2-pyridyloxymethyl, 3-(1-naphthyloxy)propyl, and the like).

    [0106] As used herein, the terms connect, connect to, connected to, attach, attach to or attached to or grammatical equivalents thereof mean to fasten on, to fasten together, to affix to, to mount to, mount on, to connect to, to join, to position onto, to position into, to place onto, or to place into. Attachment means the act of attaching or the condition of being attached. Attachment can be direct or indirectly. For example, a part A may be attached directly to part B. Alternatively, part A may be attached indirectly to part B through first attaching part A to part C and then attaching part C to part B. More than one intermediary part may be used to attach part A to part B. Attaching can be permanent, temporarily, or for a prolonged time. For example, an air care product or device of the present invention may be attached to a structure, an object, an outlet, etc. temporarily for the time necessary to perform a method of the invention. Alternatively, an air care product or device of the present invention may be attached to a structure, an object, an outlet for a prolonged time, e.g., also when a method of the present invention is not performed.

    [0107] As used herein, the terms contacting, to contact, contacted to, contacted with, or grammatical equivalents thereof are used interchangeably with the following: combining with, adding to, mixing with, passing over, incubating with, flowing over, etc. The term contacting also includes reference to placement of one substance, e.g., a freshening composition or a component of a freshening composition, as described herein, in direct physical contact or association with another component, such as a reservoir, or with another substance, such as an environment, the atmosphere, air or a surface.

    [0108] As used herein, the terms customize, customization, or grammatical equivalents refer to a process of modifying or adapting something to meet specific, desired, chosen, or predetermined requirements, preferences, or conditions. Typically, a customer or user sets the specific, desired, chosen, or predetermined requirements, preferences, or conditions.

    [0109] As used herein, the term different means not the same, not the same identity.

    [0110] As used herein, the terms effective amount, effective dose, sufficient amount, amount effective to, amount sufficient to or grammatical equivalents thereof mean a dosage or an amount sufficient to produce a desired result, whether permanent or temporary, lasting or transit that can be associated with the administration of a composition of the present invention. For example, certain freshening compositions of the present invention comprise a fragrance release modulator (FRM) in an amount sufficient to control or to modulate the release of the freshening composition or of a component thereof. In that example, the desired result is the controlled or modulated release of the freshening composition or of a component thereof, a result, which is attributed to the amount of FRM, expressed, e.g., as wt %, added to the freshening composition. An effective amount, an effective dose, a sufficient amount, an amount effective to or an amount sufficient to in the context of embodiments of the present invention can be determined by one of ordinary skill in the art using the disclosure of the present application, in particular, the Examples.

    [0111] As used herein, the term emanating surface refers to any surface that acts as a point of origin from which something is released or emitted outwardly. It refers to a material interface that, when contacted, e.g., with a freshening composition of the present invention, releases or emits atoms, molecules, ions, energy, or a smell into its surroundings. That can be achieved, e.g., by desorption (molecules leaving the surface), diffusion (atoms, molecules migrating from the bulk of a composition to the surface and out), or by chemical reaction producing gaseous or soluble products at the surface.

    [0112] As used herein, the term environment refers to surroundings or conditions a living organism (a person, an animal, or a plant) or a non-living component finds itself in or occupies. An environment includes a terrestrial environment (e.g., land, soil), an aquatic environment (e.g., marine, ocean, seas, rivers), and atmospheric environment (e.g., air) and any other spatial environment (e.g., a building, a house, a room, etc.). As used herein, an environment includes, but is not limited to, a surface of any material, item, or object, e.g., a surface of a fabric, a surface of a linen, a surface of a wood, a surface of a stone, a surface of a building, a surface of a house, a surface of a room, a surface of a piece of furniture, a surface of any, material, item, or object that may be in a building, house or room.

    [0113] As used herein, the term fragrance release modulator, abbreviated FRM, refers to a compound having the capability of modulating the release or evaporation of a freshening composition or a component thereof, when said fragrance release modulator is added to or combined with a perfume raw material as described herein. Release or evaporation of a freshening composition or of a component thereof can be tested as described herein.

    [0114] As used herein, the term freshening composition refers to a composition that comprises one or more perfume raw materials and which may be used to treat, fragrance, and/or fresh an environment, the atmosphere, the air or a surface. A freshening composition may be used with or without an air care product, referred to herein from time to time as an air freshener device. A freshening composition can be in a liquid form.

    [0115] As used herein, the terms greater than or more than include the concrete number. For example, greater than 100 or more than 100 mean greater than or equal to 100 or more than or equal to 100. As used herein, the terms smaller than, fewer than. or less than include the concrete number. For example, smaller than 100, fewer than 100, or less than 100 mean smaller than or equal to 100, fewer than or equal to 100, or less than or equal to 100. The term less than any specific number also includes 0. For example, a freshening composition comprising less than 50 wt % of an ingredient includes a freshening composition not including that ingredient.

    [0116] As used herein, the terms ingredient having antimicrobial activity or antimicrobial ingredient refer to a compound having the capability of eliminating, reducing, or minimizing the presence, occurrence, or growth of microorganisms, such as bacteria, yeasts. or molds.

    [0117] As used herein, the term ingredient having malodor counteracting activity refers to a compound having the capability of eliminating, reducing, or minimizing a malodor.

    [0118] As used herein, the term isomer refers to compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space. Isomers that differ in the arrangement of their atoms in space are termed stereoisomers. Stereoisomer and stereoisomers refer to compounds that exist in different stereoisomeric forms if they possess one or more asymmetric centers or a double bond with asymmetric substitution and, therefore, can be produced as individual stereoisomers or as mixtures. Stereoisomers include enantiomers and diastereomers. Stereoisomers that are not mirror images of one another are termed diastereomers and those that are non-superimposable mirror images of each other are termed enantiomers. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or ()-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof mixture containing equal proportions of the enantiomers is called a racemic mixture. Unless otherwise indicated, the description of compounds herein is intended to include individual stereoisomers as well as mixtures. The methods for the determination of stereochemistry and the separation of stereoisomers are well known in the art (see, discussion in Chapter 4 of ADVANCED ORGANIC CHEMISTRY, 4th edition J. March, John Wiley and Sons, New York, 1992) differ in the chirality of one or more stereocenters.

    [0119] The terms modulate, modulation, or modulating are art-recognized and refer to up-regulation (i.e., activation, stimulation, increase, facilitation, enhancement), or down regulation (i.e., inhibition, suppression, reduction, or decrease) of a response, or the two in combination or apart.

    [0124] As used herein, the terms release profile, releasing profile, or grammatical equivalents thereof in the context of a chemical composition refer to a pattern or rate at which the chemical composition or a component thereof is released from a material, formulation, or system over time. A releasing profile also is a description of how much of a chemical composition or component thereof (e.g., a freshening composition of the present invention, a drug formulation, a coating, or material) is released from the chemical composition as a function of time, environment, or other condition. When a chemical composition releases a component thereof it typically does not happen all at once. A releasing profile shows how fast and how steadily a release occurs. That can be expressed as a graph (e.g., see, Examples and Figures herein), a function (describing release kinetics (e.g., zero-order, first-order, diffusion-controlled)), or as a percentage or cumulative value showing how much of the total substance has been released over time (e.g., see, Examples and Figures herein).

    [0125] As used herein, the term scent refers to a distinctive smell and is often used to refer to a pleasant or characteristic odor produced by natural or synthetic substances, e.g., freshening compositions of then present invention. To scent means to impart a fragrance to something, or to detect a smell. While smell is meant to be neutral (good or bad), a scent usually implies a pleasant or intentional fragrance.

    [0126] As used herein, the terms smell or olfaction refer to a sensation or perception resulting from the detection of a volatile chemical substance or molecule by the olfactory system in the nose. To smell means to perceive or detect an odor through the nose or for something to emit an odor.

    [0128] As used herein, the term synthetic in the context of an agent, a compound, an ingredient, or a substance means that the agent, the compound, the ingredient, or the substance is made by chemical synthesis, i.e., is made artificially by chemical reaction(s). An agent, a compound, an ingredient, or a substance made by chemical synthesis means that after its synthesis the agent, the compound, the ingredient, or the substance imitates a corresponding natural product, e.g., has the same structure.

    [0129] As used herein, the terms treating air or a surface or fragrancing air or a surface refer to a process resulting in delivering an air freshening composition or a component thereof into the air or bringing an air freshening composition or a component thereof into contact with a surface and producing a desired result. In some embodiments of the present invention, such desired result is eliminating, reducing, or minimizing a malodor.

    [0130] Where appropriate and not contradicted by the disclosure herein, embodiments and elements/features within individual embodiments may be freely combined with those of other embodiments. As a non-limiting example, a preferred viscosity disclosed within the context of a composition itself will also be disclosed within the context of an air care product or device comprising that composition, without specifically reciting again such preferred viscosity in the context of such air care product or device. Thus, unless defined otherwise, and where consistent with the teaching herein, any feature within any embodiment of the invention may be combined with any feature within any other embodiment of the invention, and the skilled person understands and appreciates such combination as being encompassed in the original disclosure of the present application.

    [0147] Freshening compositions and fragrance release modulators (FRMs) of the present invention can be characterized by their flash point, surface tension, dynamic viscosity, density, vapor pressure, and evaporation rates. Values for flash point, surface tension, dynamic viscosity, density, and evaporation rate provided herein are measured under normal temperature and pressure (NTP) conditions. At NTP, pressure is equal to 1 atm (14.696 psi, 101.325 kPa) and temperature is equal to 293.15 K (20 C., 68 F.) (National Institute of Standards and Technology, NIST).

    [0148] The flash point of an agent, ingredient, compound, substance, or material is the lowest liquid temperature at which, under certain standardized conditions (e.g., NTP), a liquid gives off vapors in a quantity such as to be capable of forming an ignitable vapor or a mixture. The lower the flash point, the easier it is to ignite a material. There are two basic types of flash point measurements: open cup and closed cup. Both can be used to measure the flash point of a freshening composition or of a component thereof. Closed cup methods include e.g., Pensky-Martens Closed Cup (PMCC, Standard ASTM D93/ISO 2719, preferred for oil-based and alcohol-based freshening compositions and compounds), Tag Closed Cup (TCC, Standard ASTM D56, preferred for volatile freshening compositions and compounds), and SetaFlash Closed Cup (Standard ASTM D3828/ISO 3679, preferred for alcohol-based freshening compositions and compounds methods) and are art-recognized methods for measuring flash points of volatile, flammable, especially alcohol-based freshening compositions. Flash points of a freshening composition and of FRMs, as used herein, can be determined using the SetaFlash Closed Cup method.

    [0153] Freshening compositions and FRMs of the present invention also are characterized by their surface tension. Measuring the surface tension of a freshening composition is important to understand how it behaves during spraying, spreading in an environment, wetting on a surface, etc. Surface tension is the tendency of a fluid surface to shrink into the minimum surface area possible. Because of the relatively high attraction of water molecules to each other through hydrogen bonds, water has a higher surface tension (72.8 millinewtons per meter [mN/m] at 20 C.) than most other liquids. There are several methods available in the art to measure surface tension, including but not limited to, e.g., the Du Noy ring method, Wilhelmy plate method, spinning drop method, pendant drop method, bubble pressure method, drop volume method, capillary rise method, stalagmometric method, sessile drop method, Du Noy-Padday method, and drop-bounce method. Each of the above art-recognized methods can be used to measure surface tension. A preferred method to measure surface tension of a freshening composition and of FRMs, as used herein, is the Wilhelmy plate method.

    [0159] Freshening compositions and FRMs of the present invention also are characterized by their dynamic viscosity. Dynamic viscosity (also known as absolute viscosity) is the resistance to movement of one layer of a fluid over another. It is a measure of the resistance of a fluid to deform under shear stress. It is measured with various types of viscometers (e.g., capillary or vibrating) and rheometers (e.g., rotational, or microfluidic). The SI (International System of Units) unit of a dynamic viscosity is the pascal-second (Pa-s), or equivalent kilogram per meter per second (kg*m.sup.1*s.sup.1). The CGS (Centimetre-gram-second system of units) unit is called the poise (P). It is commonly expressed, particularly in ASTM (American Society for Testing and Materials) standards, as centipoise (cp) since the latter is equal to the SI multiple millipascal seconds (mPA-s). Art-recognized methods for measuring dynamic viscosity of freshening compositions and FRMs, include, but are not limited to, employing (i) Capillary Viscometer (U-Tube or Ostwald Type, measuring then time it takes for a liquid to flow through a capillary under gravity, Standard: ASTM D445, ISO 3104), (ii) Rotational Viscometer (cone-and-plate or cylinder type, measuring torque required to rotate or spindle or cone at a fixed speed in a liquid, Standard: ASTM D2196, ISO 2555), (iii) Vibrational Viscometer (measuring damping of an oscillating probe immersed in a liquid), and (iv) Microfluidic (Chip-based) Viscometer (measuring flow through a tiny microchannel using pressure sensors or flow rate detectors). A preferred method to measure dynamic viscosity of a freshening composition or of FRMs, as used herein, is employing the Capillary Viscometer method.

    B. Fragrance Release Modulators (Frms)

    [0242] In some embodiments of the present invention, a freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, an air freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a liquid freshening composition a fragrance release modulator. In some embodiments of the present invention, a clear freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a homogenous freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a clear liquid freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a liquid air freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a homogeneous clear liquid air freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a homogeneous clear liquid air freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a non-water-based air freshening composition comprises a fragrance release modulator. Sometimes, herein a fragrance release modulator is referred to as drop-in-fragrance release modulator or drop-in FRM. It is understood and one of ordinary skill in the art will appreciate that, if not clearly contradicted by the content of this specification, each embodiment of a fragrance release modulator and/or features/elements disclosed as part of that embodiment can be combined with any of the embodiments hereinabove or hereinbelow.

    [0243] When a freshening composition comprises a perfume raw material and a fragrance release modulator, those ingredients are different.

    [0244] Unexpectedly and surprisingly, the inventors have found that specific combinations of a perfume raw material and a fragrance release modulator (FRM) permit the customization, control, and modulation of (i) the lifespan of a freshening composition and (ii) control the releasing profile of the freshening composition. This customization, control, and modulation can be achieved regardless of a solvent or diluent being present in the freshening composition. Examples E, F, G, H, K, and L describe customization, control, and modulation of a freshening composition in the presence of a solvent or diluent, while Examples N and O describe such customization, control, and modulation in the absence of a solvent or diluent. This customization, control and modulation can also be achieved regardless of which wicking device is used. For example, if the wicking device is a reed or a plurality of reeds, a wick or a plurality of wicks, a stick or a plurality of sticks, a fiber or a plurality of fibers, a mesh, or a combination thereof, there is no need to intervene, no need to touch the delivery device or to reverse the flow of the freshening composition through the delivery device during product usage. Moreover, at the end of product usage the reservoir in the delivery device holding the freshening composition, is substantially completely empty.

    [0245] Further, and equally surprisingly and unexpectedly, the inventors have found that it will be possible to establish a two-stage functional regime and to customize, control and modulate the release of a freshening composition or of a component thereof by controlling the transport process of the freshening composition inside of, e.g., a wicking system to an emanating surface by using a drop-in fragrance release modulator (FRM). More specifically, the inventors have found that by using the drop-in FRM it will be possible to alter, modulate, control, and customize the surface tension, the dynamic viscosity, and the density of such freshening composition. That discovery allows for the optimization, customization, modulation, and control of the mass transport of a freshening composition through a delivery engine, such as a reed, a stick, a fiber, a mesh, a wick, a membrane, a porous or a semi-porous material. Thus, in some embodiments of the present invention, a fully saturated emanating surface is provided, whereby the lifespan of the air care product is optimized, customized, and controlled. Further, the strength, character, and diffusivity of the scent irrespective of the perfume raw material used, can be optimized, and controlled without altering the capability of the freshening composition to, e.g., address other functions, such as to counteract malodor ingredients or compositions or to have insect repelling activity.

    [0246] Surprisingly and unexpectedly, the inventors have found that the mass transfer process of a freshening composition inside a wicking or diffusing element, as well as the mass transfer and the diffusion process of the freshening composition can be altered, customized, modulated, and controlled when specific compounds, herein described as fragrance release modulators (FRM), are dropped into a perfume raw material or blend of perfume raw materialswith or without a solvent or diluentto formulate a freshening composition. The FRM can significantly influence the wicking process inside the delivery device (further described herein), and the releasing rate of the freshening composition at the surface of the emanating device by altering the surface tension, the dynamic viscosity, the density, the flash point, and the volatility of the freshening composition. In other words, an FRM, as described herein, permits the control, the customization, and the modulation of diffusivity and long-lasting characteristics of a freshening composition or of a component thereof, including, but not limited to, the perceived scent's character, the intensity and lifespan of the product. Due to the presence of an FRM, a freshening composition can be released through a two-stage process: (i) an initial transitory regime, which is associated with unusually high amount of freshening composition release, and (ii) a steady-state release regime, which implies a linear release of the freshening composition into an external environment until, or very close to its full completion (see, Examples).

    [0247] As described herein, an FRM helps to formulate long-lasting air freshening products with customized releasing time, e.g., when the delivery device is a wicking or a diffusing device. There are no known formulation restrictions regarding the selection of perfume raw material, fragrance ingredients, flavor ingredients, essential oils, or functional ingredients that can be employed in combination with an FRM. Further, the inventors have not found any limitation with respect to the type of ingredient and the concentration of such ingredient when used in combination with an FRM.

    [0248] By dropping an FRM into a freshening composition, which comprises a perfume raw material, the inventors surprisingly and unexpectedly have found that it is possible to control and customize (i) the surface tension of the freshening composition; (ii) the dynamic viscosity of the freshening composition; (iii) the density of the freshening composition; and (iv) the flash point of the freshening composition, all measured under normal temperature and pressure (NTP) conditions. This finding permits the control of the two critical steps associated with the releasing process of the freshening compositions: (i) the capillary mass transfer of the freshening composition through the delivery element, which can be a reed, stick, fiber, mesh, wick, semiporous or porous materials; and (ii) the phase and mass transfer processes of the freshening composition at the emanating surface.

    [0249] Freshening compositions of the present invention comprise specific amounts and compositions of FRM, depending on the desired application. FRMs generally are odorless or low-odor, non-fragrance materials, but fragrance-miscible compounds. They may be used in combination with any perfume raw material (PRM) described herein, i.e., in combination with one or more of an ester, an alcohol, an aldehyde, a ketone, an acetal, a phenol, an ether, a lactone, a furan, a hydrocarbon, an acid, a natural origin fragrance compound, a synthetic origin fragrance compound, stereoisomers, and mixtures thereof, without any restriction, and without any negative impact on the freshening competition's hedonic character and strength, as well as the freshening composition's targeting purpose.

    [0250] In some embodiments of the present invention, a fragrance release modulator comprises one or more ingredients having almost no hedonic impact on a person's fragrance experience. Those ingredients permit emanating a surface to quickly saturate and to operate as a steady saturated surface during the delivery process of the freshening composition.

    [0251] The inventors have found that FRMs described herein when combined with a perfume raw material to form a freshening composition bestow the desired and superior characteristics upon the freshening composition. The inventors have found the following FRMs most useful: C.sub.2-8 linear and C.sub.2-8 branched alcohols, alkyl- and aryl compounds, silicon compounds, and organic ester compounds, specifically cyclic carbonate esters.

    [0252] Thus, in some embodiments of the present invention, an FRM is selected from the group consisting of a C.sub.2-8 linear alcohol, a C.sub.2-8 branched alcohol, an alkyl compound, an aryl compound, a silicon compound, an organic ester compound, a cyclic carbonate ester compound, a stereoisomer of any preceding fragrance release modulator, and a mixture of any of the preceding release modulators.

Weight percentage is made with reference to the total weight of the freshening composition.

A preferred C.sub.2-8 branched alcohol is 3-methyl-3-methoxyl butanol, sometimes referred herein as MMB or as 3-methoxy-3-methyl-1-butanol. 3-methyl-3-methoxyl butanol has CAS Number 56539-66-3. Freshening compositions comprising 3-methyl-3-methoxyl butanol (MMB) as an FRM are described herein, e.g., in Examples E, F, K, L, N, and O.

    [0299] In some embodiments of the present invention, a freshening composition of the present invention comprises a fragrance release modulator in a range from about 0.01 wt % to about 99 wt %, in a range from about 0.02 wt % to about 95 wt %, in a range from about 0.05 wt % to about 95 wt %, in a range from about 0.1 wt % to about 95 wt %, in a range from about 0.2 wt % to about 95 wt %, in a range from about 0.5 wt % to about 95 wt % in a range from about 1 wt % to about 95 wt % in a range from about 2 wt % to about 90 wt % in a range from about 3 wt % to about 85 wt % in a range from about 5 wt % to about 80 wt % in a range from about 10 wt % to about 75 wt %, in a range from about 15 wt % to about 70 wt %, in a range from about 20 wt % to about 65 wt %, in a range from about 25 wt % to about 60 wt %, in a range from about 30 wt % to about 55 wt %, in a range from about 40 wt % to about 50 wt %, with the weight percentages being relative to the total weight of the freshening composition.

    [0300] In some embodiments of the present invention, a freshening composition of the present invention comprises a fragrance release modulator in a range between about 0.01 wt % and about 99 wt %, in a range between about 0.02 wt % and about 95 wt %, in a range between about 0.05 wt % and about 95 wt %, in a range between about 0.1 wt % and about 95 wt %, in a range between about 0.2 wt % and about 95 wt %, in a range between about 0.5 wt % and about 95 wt %, in a range between about 1 wt % and about 95 wt %, in a range between about 2 wt % and about 90 wt %, in a range between about 3 wt % and about 85 wt %, in a range between about 5 wt % and about 80 wt %, in a range between about 10 wt % and about 75 wt %, in a range between about 15 wt % and about 70 wt %, in a range between about 20 wt % and about 65 wt %, in a range between about 25 wt % and about 60 wt %, in a range between about 30 wt % and about 55 wt %, in a range between about 40 wt % and about 50 wt %, with the weight percentages being relative to the total weight of the freshening composition.

    [0301] Preferably, a freshening composition comprises from about 0.01 wt % to about 90 wt % fragrance release modulator (FRM); preferably, less than about 75 wt % FRM; more preferably, less than about 50 wt % FRM; and most preferably less than about 25 wt % FRM, with the weight percentages being relative to the total weight of the freshening composition.

    [0302] In some embodiments of the present invention, a freshening composition comprises a fragrance release modulator in an amount sufficient (typically provided herein as wt % of the freshening composition) to control (or modulate) the release of the freshening composition or of a component thereof. Adding an FRM to a freshening composition, as described herein, allows the user to control (or modulate) the release of the freshening composition or a component thereof into or onto an environment. Depending on the desirability of a user, the release of a freshening composition or of a component thereof can be up-regulated (faster) or down-regulated (slower), compared to a control not comprising an FRM. When a freshening composition comprises (i) X wt % perfume raw material and (ii) Y wt % fragrance release modulator, a control not comprising an FRM would comprise 100 wt % perfume raw material (e.g., see, Examples N and O). When a freshening composition comprises (i) X wt % perfume raw material, (ii) Y wt % fragrance release modulator, and (iii) W wt % solvent or diluent, a control not comprising an FRM would comprise (i) X wt % perfume raw material and (ii) W+Y wt % solvent or diluent (e.g., see, Examples G, H, and K). Likewise, when a freshening composition comprises (i) X wt % perfume raw material, (ii) Y wt % fragrance release modulator, (iii) W wt % solvent or diluent, and (iv) V wt % of an ingredient having a functional activity, a control not comprising an FRM would comprise (i) X wt % perfume raw material (ii) V wt % of an ingredient having a functional activity, and (iii) W+Y wt % solvent or diluent.

    [0303] In some embodiments of the present invention, release of a freshening composition or of a component thereof is up-regulated or accelerated, i.e., the release of the freshening composition or of a component thereof is faster than what is observed with a control (i.e., a freshening composition not comprising the FRM, but otherwise similar). As exemplified by Example E (FIG. 3) certain FRMs, such as triethyl citrate (TEC), benzyl benzoate (BB), ethanol, 3-methyl-3-methoxyl butanol (MMB) and dipropylene glycol (DPG) up-regulate release of a freshening composition wherein the freshening composition comprises in addition to the FRM and a perfume raw material the solvent 2,2-dimethyl-1,3-dioxolane-4-methanol (Augeo Clean Multi brand name from Solvay). When the identity and amount of the PRM and solvent are kept constant, the extent of up-regulation depends on the identity of the FRM (see, Example E, FIG. 3; Example F, FIG. 4). In some embodiments of the present invention, a fragrance release modulator of the present invention up-regulates the release or evaporation of a freshening composition or of a component thereof, relative to a control (not comprising said fragrance release modulator and being assigned a value of 100%) by at least about 0.5%, by at least about 1%, by at least about 2%, by at least about 3% by at least about 5%, by at least about 10%, by at least about 20%, by at least about 30%, by at least about 40%, by at least about 50%, by at least about 60%, by at least about 70%, by at least about 80%, by at least about 90%, by at least about 100%, by at least about 110%, by at least about 120%, by at least about 130%, by at least about 140%, by at least about 150%, by at least about 160%, by at least about 170%, by at least about 180%, by at least about 190%, by at least about 200%, by at least about 250%, by at least about 300%, by at least about 400%, by at least about 500%, or by at least about 1,000-3,000% or more. Values for the % up-regulation are statistically significant.

    [0304] A user is able to verify directly and positively such faster release (compared to a control) by, e.g., measuring the time it takes for the freshening composition or component thereof to be fully released (will be faster than the control) or weighing the freshening composition and noticing a reduced weight (compared to the control) over time. Details are described in the Examples herein. For example, the fragrance release modulator MMB when combined with either the Apple Fragrance (see, Example N, FIG. 11) or the Floral Fresh Fragrance (see, Example O, FIG. 12) lead to a faster release of the freshening composition or component thereof. Also, the fragrance release modulator hexylene glycol when combined with either the Apple Fragrance (see, Example N, FIG. 11) or the Floral Fresh Fragrance (see, Example O, FIG. 12) lead to a faster release of the freshening composition or component thereof.

    [0305] On the other hand, in some embodiments of the present invention, adding an FRM allows a user to down-regulate or slow-down the release of the freshening composition or of a component thereof.

    [0306] In some embodiments of the present invention, a fragrance release modulator of the present invention down-regulates the release or evaporation of a freshening composition or of a component thereof, relative to a control (not comprising said fragrance release modulator and assigned a value of 100%) by at least about 0.5%, by at least about 1%, by at least about 2%, by at least about 3%, by at least about 5%, by at least about 10%, by at least about 15%, by at least about 20%, by at least about 25%, by at least about 30%, by at least about 35%, by at least about 40%, by at least about 45%, by at least about 50%, by at least about 55%, by at least about 60%, by at least about 65%, by at least about 70%, by at least about 75%, by at least about 80%, by at least about 85%, by at least about 90%, or by at least about 95% or more. Values for the % down-regulation are statistically significant.

    [0307] A user is able to verify directly and positively such slower release (compared to a control) by, e.g., measuring the time it takes for the freshening composition or component thereof to be fully released (will be slower than the control) or weighing the freshening composition and noticing a higher weight (compared to the control) over time. Details are described in the Examples herein. For example, the fragrance release modulator triethyl citrate (TEC) when combined with either the Apple Fragrance (see, Example N, FIG. 11) or the Floral Fresh Fragrance (see, Example O, FIG. 12) lead to a slower release of the freshening composition or component thereof.

    [0308] Some fragrance release modulators, exemplified by dipropylene glycol (DPG), have the capacity of either up-regulating or downregulating the release of a freshening composition or of a component thereofdepending on the perfume raw material. For example, the fragrance release modulator dipropylene glycol (DPG) when combined with the Apple Fragrance slows down the release of the freshening composition or of a component thereof (see, Example N, FIG. 11). However, when combined with the Floral Fresh Fragrance, the fragrance release modulator dipropylene glycol (DPG) leads to a faster release of the freshening composition or of a component thereof (see, Example O, FIG. 12).

    [0309] Unexpectedly and surprisingly, the inventors have found that the amount (wt %) of an FRM in a freshening composition determines the % up- or % downregulation of release of a freshening composition or of a component thereof (e.g., see, Example G and FIG. 5, Example H and FIG. 6, Example K and FIG. 9, and Example L and FIG. 10). When the wt % of the perfume raw material is kept constant and the wt % of a solvent or diluent is adjusted to compensate for the various wt % of an FRM present in the freshening composition, varying the wt % of an FRM, as exemplified by the FRM benzyl benzoate (BB), the release of the freshening composition or of the component can be modulated to a customized rate (e.g., see, Example G and FIG. 5, Example H and FIG. 6, Example K and FIG. 9, and Example L and FIG. 10). As can be seen in those Examples, a low wt % of the FRM benzyl benzoate (7.5 wt %) in the freshening composition leads to the fast release. Increasing the wt % of the FRM benzyl benzoate in the freshening composition to e.g., 25 wt %, 42.5 wt % or 50 wt % leads to a slower release of the freshening composition or of a component thereof, compared to the release caused by the FRM at 7.5 wt %. The release of the freshening composition mediated by the FRM benzyl benzoate being present at 50 wt % is slower than the release mediated by 42.5 wt %. The release of the freshening composition mediated by the FRM benzyl benzoate being present at 42.5 wt % is slower than the release mediated by 25 wt %. The release of the freshening composition mediated by the FRM benzyl benzoate being present at 25 wt % is slower than the release mediated by 7.5 wt %. This finding is observed with various freshening compositions comprising different perfume raw materials, e.g., Apple fragrance (see, Example G and FIG. 5; Example L and FIG. 10) or Floral Fresh fragrance (see, Example H and FIG. 6; Example K and FIG. 9). This finding is also observed with various freshening compositions comprising different solvents or diluents, e.g., 2,2-dimethyl-1,3-dioxolane-4-methanol (Augeo Clean Multi brand name from Solvay; see, Example G and FIG. 5; Example L and FIG. 10) or 3-methyl-1,3-butanediol-1-acetate (IPD-AC brand name from Kuraray, which is 3-hydroxy-3-methylbutyl acetate, an acetate ester derived from 3-methyl-1.3-butanediol; see, Example H and FIG. 6; Example K and FIG. 9).

    [0310] Unexpectedly and surprisingly, the inventors have found that some FRMs can be used to up-regulate and to down-regulate release of a freshening composition or of a component thereof. As exemplified by the FRM benzyl benzoate (BB), compared to a control freshening composition not comprising an FRM, lower amounts of BB (e.g., 7.5 wt % and 25 wt %) in a freshening composition lead to an up-regulation of release of the freshening composition or of a component thereof while higher wt % of the BB (42.5 wt % and 50 wt %) in the freshening composition lead to down-regulation of release of the freshening composition or of a component thereof (e.g., see, Example G and FIG. 5; Example L and FIG. 10). Up-regulation of release leads to faster evaporation of the freshening composition or of the component thereof. Thus, in some embodiments of the present invention when a faster evaporation of the freshening composition is desired, a user would add a lower amount of an FRM (e.g., the FRM benzyl benzoate) to the freshening composition. Down-regulation of release leads to slower evaporation of the freshening composition or of the component thereof. Thus, in some embodiments of the present invention when a slower evaporation of the freshening composition is desired, a user would add a larger amount of an FRM (e.g., the FRM benzyl benzoate) to the freshening composition.

The present invention provides freshening compositions that are in compliance with requirements imposed by those agencies.

    [0316] The inventors have established certain key performance requirements (KPRs) for a solvent to be used for the formulation of a liquid freshening composition as described herein, preferably, for the formulation of a freshening composition for use with a wicking delivery device. According to those KPRs, a preferred solvent is completely miscible with any perfume raw material described herein. A preferred solvent is odorless, or at least of low odor. Also, according to those KPRs, a preferred solvent easily wicks through a delivery device as described herein without clogging it. Another characteristic of a solvent for use in formulating a freshening composition is to easily diffuse from the emanating surface of a delivery device into an external environment, the atmosphere, air, or onto an external surface. Other preferred characteristics of a solvent include compliance with safety requirements, such as being CARB-accepted. Further, they should be cost effective, readily available, and preferably, sustainable.

It is understood and one of ordinary skill in the art will appreciate that, if not clearly contradicted by the content of this specification, each embodiment of an air care product or device comprising an evaporative surface and/or features/elements disclosed as part of that embodiment can be combined with any of the embodiments hereinabove or hereinbelow.

    [0405] In some embodiments of the present invention, an evaporative surface may be integral or separate from an evaporative assistance element and/or the delivery engine. The evaporative surface may be configured as a porous or semi-porous substrate, a bowl or a plate. That substrate, bowl or plate can be made of wood, of plastic, of glass, of metal or of a combination of any of the preceding materials.

    [0406] In some embodiments of the present invention, an air care product or device comprises an evaporative assistance element. An evaporative assistance element may be used to achieve or facilitate the evaporation of a freshening composition or of a component thereof from the air care product. Such an evaporative assistance element may be configured in various ways. In some embodiments of the present invention, an evaporative assistance element is selected from the group consisting of a heater, a fan, an agitation member, a powered agitator, a manual agitator, and a combination thereof.

    [0407] In some embodiments of the present invention, an evaporative assistance element is a heater comprising one or more heating elements.

A preferred energized device comprises a control system such that the heater temperature is adjustable. In some embodiments of the present invention, a control system also cycles the heater temperature to provide greater control over the evaporation process of the freshening composition.

    F. Spraying Devices

    [0410] A preferred air care product is spraying device comprising a freshening composition of the present invention. It is well within the art to convert a freshening composition of the present invention into an aerosol and then use it as a spray. Essentially, a system comprising a freshening composition of the present invention, a container, a propellant, a valve, an actuator/a nozzle allowing the freshening composition of the present invention to be atomized into fine droplets or particles and sprayed into or onto an environment, is designed. It then can be released under pressure.

    [0411] It is understood that before a freshening composition of the present invention can be sprayed it must be dispersible in a solvent/propellant system. Further, it is noted that the freshening composition of the present invention is chemically compatible with the chosen propellant and container materials so that no reaction, corrosion, or phase separation takes place.

    [0412] Another requirement is that the freshening composition of the present invention has a viscosity low enough to flow and atomize through the nozzle of the spraying device, typically less than 100 cP.

    [0413] Choosing a propellant that provides the pressure that expels and atomizes a product such as a freshening composition of the present invention, also is well known in the art. Essentially, there are two broad categories for use as propellants: compressed gases and liquefied gases. In some embodiments of the present invention a spraying device comprises a compressed gas as a propellant. Compressed gases include, but are not limited, to, e.g., nitrogen, carbon dioxide, air, and the like. In some embodiments of the present invention a spraying device comprises a liquefied gas as a propellant. Liquefied gases include, but are not limited to, e.g., propane, butane, isobutane, dimethyl ether, hydrofluorocarbons, and the like. In some embodiments of the present invention, a propellant is a volatile organic solvent (e.g., ethanol), an isoparaffinic hydrocarbon (e.g., Isopar grades), or a volatile silicone (e.g., cyclomethicone) to carry the freshening composition, combined with a liquefied hydrocarbon propellant (e.g., propane, n-butane, isobutane, blends or mixtures thereof) or dimethyl ether (DME).

    [0414] Various formulations comprising various ratios of (i) a freshening composition of the present invention, (ii) a co-solvent and (iii) a propellant can be made and used. In some embodiments of the present invention, a spraying device comprises an aerosol spray comprising (i) from about 0.01 wt % to about 50 wt % of a freshening composition of the present invention, (ii) from about 1 wt % to about 80 wt % of a co-solvent, and (iii) from about 1 wt % to about 50 wt % of a propellant. In some embodiments of the present invention, a spraying device comprises an aerosol spray comprising (i) from about 1 wt % to about 20 wt % of a freshening composition of the present invention, (ii) from about 30 wt % to about 80 wt % of a co-solvent, and (iii) from about 5 wt % to about 30 wt % of a propellant. Useful co-solvents include, but are not limited to, e.g., ethanol, an isoparaffin, a volatile silicone, and blends and mixtures thereof. Useful propellants include, but are not limited to, e.g., propane, butane, isobutane, DME, blends and mixtures thereof.

    [0415] As an alternative to using propellants, one can use pump (non-pressurized) sprays with ethanol instead. Various ratios of freshening composition to ethanol in a pump spray can be employed. A preferred pump spray comprises from about 5 wt % to about 30 wt %, of a freshening composition of the present invention and from about 70 wt % to about 95 wt % ethanol.

    [0416] In some embodiments of the present invention, a co-solvent may be added to a freshening composition of the present invention and a propellant to, e.g., adjust viscosity, control droplet size and to ensure a uniform spray pattern. Suitable co-solvents include, but are not limited to, e.g., ethanol, acetone, mineral spirits and isoparaffins. Care will be taken that a cosolvent does not negatively impact any of the desired characteristics of a freshening composition of the present invention, including its smell and scent.

    [0417] Further, it is within the knowledge of a skilled artisan to select a suitable container for the spraying device, e.g., a can or a bottle. The container typically is made of metal (tinplate or aluminum) or plastic. It is rated for pressure (typically from about 3 to 10 atm). Attached to the container is a valve assembly controlling the flow rate and product release. Further attached to the container is an actuator or a nozzle designed to atomize a freshening composition of the present invention into the desired spray pattern, e.g., a fine mist. Each of the components of the delivery system (container, valve assembly, actuator/nozzle) are pressure rated and chemically resistant to the freshening composition. The components are properly sealed to prevent leakage or premature, undesired evaporation of the freshening composition.

    [0418] The aerosol must deliver not only a desired droplet size, typically from about 1 to 50 micrometers for fine mist but also a desired spray rate and angle, stable pressure throughout its shelf life and no phase separation or clogging. To achieve that, a skilled artisan will resort to techniques known in the art and properly adjust the ratio of freshening composition to propellant, solvent volatility, nozzle design and may add viscosity modifiers.

    [0419] The filling of the container (transferring a freshening composition of the present invention into the container) typically is done in a pressurized environment. The valve, and actuator/nozzle are crimped onto the container. A desired propellant is injected either through the valve (under pressure) or by cold-filling (liquid propellant added at low temperature. After filling, the container is leak-tested and weighed to ensure correct fill.

    [0420] When the aerosol is sprayed, a pressurized liquid composition (freshening composition, co-solvent when present, propellant) inside the container is released through a nozzle turning the liquid composition into a fine mist or spray of tiny droplets or particles suspended in air, i.e., into or onto an environment. After the spraying, the propellant quickly diffuses into the air. The freshening composition and co-solvent, may evaporate in the air (e.g., freshening the air) or deposit on a surface (e.g., coating a fabric, as further described herein).

    [0421] Testing and validation of a spraying device of the present invention includes, but is not limited to, e.g., spray pattern analysis, pressure retention and leakage tests, evaporation rate and droplet size measurements, and chemical stability testingusing techniques known in the art.

    D. Methods for Customizing, Controlling, and/or Modulating the Release of a Freshening Composition or of a Component Thereof

    [0526] The present invention also provides methods for customizing, controlling, and/or modulating the release of a freshening composition or of a component thereof. It is understood and one of ordinary skill in the art will appreciate that, if not clearly contradicted by the content of this specification, each embodiment of a method for customizing, controlling, and/or modulating the release of a freshening composition or of a component thereof and/or features/elements disclosed as part of that embodiment can be combined with any of the embodiments hereinabove or hereinbelow.

    [0527] As described in great detail herein, the inventors have found that the release of a freshening composition or of a component thereof can be customized, controlled, or modulated by employing fragrance release modulators. Employing such fragrance release modulators allows for a customizable control of the release of a freshening composition or of a component thereof. By customized is meant that by adding a fragrance release modulator in a specific amount (wt %) to a freshening composition, the release profile of a freshening composition or of a component thereof, can be changed in a desired way. For example, by adding the fragrance release modulator benzyl benzoate (BB) in increasing amounts to a freshening composition the release of the freshening composition or of a component thereof can be decreased, slowed down, or down-regulated over a desired period of time (e.g., see, FIGS. 9 and 10). Thus, in view of the teaching herein (see also, Examples and Figures), one of ordinary skill in the art will be able to add a specific wt % of a fragrance release modulator to a freshening composition to achieve a desired percentage release of a freshening composition or of a component thereof by a specific day. By way of example (see, Example N, FIG. 11), a skilled artisan would add 50 wt % of the FRM hexylene glycol to an Apple Fragrance to obtain a desired about 60.00% release of that freshening composition or of a component thereof by day 14. Likewise, a skilled artisan would add 50 wt % of the FRM triethyl citrate (TEC) to the same freshening composition if by day 14 only an about 22% release of the freshening composition would be desired. Using the teaching of the instant application, a skilled artisan will be able to customize the release profile of any perfume material, of any freshening composition or any component thereof, irrespective of what perfume material is used to formulate such freshening composition. As such, a skilled artisan will be able to increase (by slowing down the release of the freshening composition or component thereof) or decrease (by increasing the release of the freshening composition or component thereof) the life span of a freshening composition, simply by adding to the freshening composition a fragrance release modulator which brings about such effect. The Examples provided herein provide guidance to adjust the amount (wt %) of an FRM in a freshening composition to achieve any such desired result over a chosen time period.

    [0528] As exemplified by Example E (FIG. 3) certain FRMs, such as triethyl citrate (TEC), benzyl benzoate (BB), ethanol, 3-methyl-3-methoxyl butanol (MMB) and dipropylene glycol (DPG) up-regulate release of a freshening composition wherein the freshening composition comprises in addition to the FRM and a perfume raw material the solvent 2,2-dimethyl-1,3-dioxolane-4-methanol (Augeo Clean Multi brand name from Solvay). When the identity and amount of the PRM and solvent are kept constant, the extent of up-regulation depends on the identity of the FRM (see, Example E, FIG. 3; Example F, FIG. 4). In freshening compositions not comprising a solvent, for example, the fragrance release modulator MMB when combined with either the Apple Fragrance (see, Example N, FIG. 11) or the Floral Fresh Fragrance (see, Example O, FIG. 12) lead to a faster release of the freshening composition or component thereof. Also, the fragrance release modulator hexylene glycol when combined with either the Apple Fragrance (see, Example N, FIG. 11) or the Floral Fresh Fragrance (see, Example O, FIG. 12) lead to a faster release of the freshening composition or component thereof. Thus, in some embodiments of the present invention, a fragrance release modulator is used to up-regulate, to increase the release of a freshening composition or of a component thereof.

    [0529] In some embodiments of the present invention, a method for customizing, controlling, and/or modulating the release of a freshening composition or of a component thereof comprises the step of combining an amount (wt %) of a fragrance release modulator as described herein with a perfume raw material as described herein to form a freshening composition so that an up-regulation of the release of the freshening composition or of a component thereof, relative to a control (not comprising said fragrance release modulator and assigned a value of 100%) by at least about 0.5%, by at least about 1%, by at least about 2%, by at least about 3% by at least about 5%, by at least about 10%, by at least about 20%, by at least about 30%, by at least about 40%, by at least about 50%, by at least about 60%, by at least about 70%, by at least about 80%, by at least about 90%, by at least about 100%, by at least about 110%, by at least about 120%, by at least about 130%, by at least about 140%, by at least about 150%, by at least about 160%, by at least about 170%, by at least about 180%, by at least about 190%, by at least about 200%, by at least about 250%, by at least about 300%, by at least about 400%, by at least about 500%, or by at least about 1,000-3,000% or more is obtained. In some embodiments, up-regulation is by at least about 5%. In some embodiments, up-regulation is by at least about 10%. Upregulation can be determined as described herein.

In some embodiments, up-regulation is by at least about 5%. In some embodiments, up-regulation is by at least about 10%. Up-regulation can be determined as described herein.

    [0531] In some embodiments of the present invention, a method for customizing, controlling, and/or modulating the release of a freshening composition or of a component thereof comprises the step of combining an amount (wt %) of a fragrance release modulator as described herein with a perfume raw material as described herein and a solvent or diluent as described herein to form a freshening composition so that an up-regulation of the release of the freshening composition or of a component thereof, relative to a control (not comprising said fragrance release modulator and assigned a value of 100%) by at least about 0.5%, by at least about 1%, by at least about 2%, by at least about 3% by at least about 5%, by at least about 10%, by at least about 20%, by at least about 30%, by at least about 40%, by at least about 50%, by at least about 60%, by at least about 70%, by at least about 80%, by at least about 90%, by at least about 100%, by at least about 110%, by at least about 120%, by at least about 130%, by at least about 140%, by at least about 150%, by at least about 160%, by at least about 170%, by at least about 180%, by at least about 190%, by at least about 200%, by at least about 250%, by at least about 300%, by at least about 400%, by at least about 500%, or by at least about 1,000-3,000% or more is obtained. In some embodiments, up-regulation is by at least about 5%. In some embodiments, up-regulation is by at least about 10%. Up-regulation can be determined as described herein.

    [0532] In some embodiments of the present invention, a method for customizing, controlling, and/or modulating the release of a freshening composition or of a component thereof comprises the step of combining an amount (wt %) of a fragrance release modulator as described herein with a perfume raw material as described herein, a solvent or diluent as described herein, and a functional ingredient as described herein, to form a freshening composition so that an upregulation of the release of the freshening composition or of a component thereof, relative to a control (not comprising said fragrance release modulator and assigned a value of 100%) by at least about 0.5%, by at least about 1%, by at least about 2%, by at least about 3% by at least about 5%, by at least about 10%, by at least about 20%, by at least about 30%, by at least about 40%, by at least about 50%, by at least about 60%, by at least about 70%, by at least about 80%, by at least about 90%, by at least about 100%, by at least about 110%, by at least about 120%, by at least about 130%, by at least about 140%, by at least about 150%, by at least about 160%, by at least about 170%, by at least about 180%, by at least about 190%, by at least about 200%, by at least about 250%, by at least about 300%, by at least about 400%, by at least about 500%, or by at least about 1,000-3,000% or more is obtained. In some embodiments, up-regulation is by at least about 5%. In some embodiments, up-regulation is by at least about 10%. Upregulation can be determined as described herein.

    [0533] While the FRM triethyl citrate (TEC) in lower concentrations (e.g., 7.5 wt %, Example E, FIG. 3 and Example L, FIG. 10), leads to a faster increase of release of a freshening composition or of a component thereof, at higher concentrations (e.g., at 50 wt %, Example N, FIG. 11, and Example O, FIG. 12), it leads to a slower release of a freshening composition or of a component thereof. Similarly, increasing the concentration of the FRM benzyl benzoate (BB) in a freshening composition, i.e., the wt % of BB in a freshening composition, a decrease, i.e., a down-regulation of release of the freshening composition or of the component thereof is observed (e.g., see, Example K, FIG. 9, and Example L, FIG. 10). Thus, in some embodiments of the present invention, a fragrance release modulator is used to down-regulate, to reduce the release of a freshening composition or of a component thereof.

    [0534] In some embodiments of the present invention, a method for customizing, controlling, and/or modulating the release of a freshening composition or of a component thereof comprises the step of combining an amount (wt %) of a fragrance release modulator as described herein with a perfume raw material as described herein to form a freshening composition so that a down-regulation of the release of the freshening composition or of a component thereof, relative to a control (not comprising said fragrance release modulator and assigned a value of 100%) by at least about 0.5%, by at least about 1%, by at least about 2%, by at least about 3%, by at least about 5%, by at least about 10%, by at least about 15%, by at least about 20%, by at least about 25%, by at least about 30%, by at least about 35%, by at least about 40%, by at least about 45%, by at least about 50%, by at least about 55%, by at least about 60%, by at least about 65%, by at least about 70%, by at least about 75%, by at least about 80%, by at least about 85%, by at least about 90%, or by at least about 95% or more is obtained. In some embodiments, down-regulation is by at least about 5%. In some embodiments, down-regulation is by at least about 10%. Down-regulation can be determined as described herein.

In some embodiments, down-regulation is by at least about 10%. Down-regulation can be determined as described herein.

In some embodiments, downregulation is by at least about 10%. Down-regulation can be determined as described herein.

    [0538] Thus, the present invention provides a method for customizing, controlling, and/or modulating the release of a freshening composition or a component thereof.

    Example C. General Consideration and the Influence of Different Solvents on the Release and Evaporation of a Freshening Composition Comprising 50 Wt % Apple Fragrance

    [0564] Any freshening composition comprising ingredients disclosed herein may be formulated by a skilled artisan. For example, a skilled person will be able to formulate a freshening composition comprising (i) from about 0.1 wt % to about 95 wt % perfume raw material and (ii) from about 0.01 wt % to about 90 wt % fragrance release modulator by combining (i) from about 0.1 wt % to about 95 wt % of any perfume raw material disclosed herein and (ii) from about 0.01 wt % to about 90 wt % of any fragrance release modulator disclosed herein. Further, a skilled person will be able to formulate a freshening composition comprising (i) from about 0.1 wt % to about 95 wt % perfume raw material, (ii) from about 1.0 wt % to about 95 wt % of a solvent, and (iii) from about 0.01 wt % to about 90 wt % fragrance release modulator by combining (i) from about 0.1 wt % to about 95 wt % of any perfume raw material disclosed herein, (ii) from about 1.0 wt % to about 95 wt % of any solvent disclosed herein, and (iii) from about 0.01 wt % to about 90 wt % of any fragrance release modulator disclosed herein. Further, a skilled person will be able to formulate a freshening composition comprising (i) from about 0.1 wt % to about 95 wt % perfume raw material, (ii) from about 0.01 wt % to about 90 wt % fragrance release modulator, and (iii) less than about 50 wt % of an ingredient having a functional activity by combining (i) from about 0.1 wt % to about 95 wt % of any perfume raw material disclosed herein, (ii) from about 0.01 wt % to about 90 wt % of any fragrance release modulator disclosed herein, and (iii) less than about 50 wt % of any ingredient having a functional activity disclosed herein. Further, a skilled person will be able to formulate a freshening composition comprising (i) from about 0.1 wt % to about 95 wt % perfume raw material, (ii) from about 1.0 wt % to about 95 wt % of a solvent, (iii) from about 0.01 wt % to about 90 wt % fragrance release modulator, and (iv) less than about 50 wt % of an ingredient having a functional activity by combining (i) from about 0.1 wt % to about 95 wt % of any perfume raw material disclosed herein, (ii) from about 1.0 wt % to about 95 wt % of any solvent disclosed herein, (iii) from about 0.01 wt % to about 90 wt % of any fragrance release modulator disclosed herein, and (iv) less than about 50 wt % of any ingredient having a functional activity disclosed herein. There is no preferred order of adding the individual ingredients to each other when formulating a freshening composition of the present invention, e.g., a liquid freshening composition or a non-water-based freshening composition. The freshening composition forms by gentle mixing the perfume raw material(s) with the fragrance release modulator(s), solvent(s) or diluent(s), and where desired with the ingredient(s) having a functional activity. A clear, temperature stable freshening composition forms.

    [0565] The resulting freshening compositions were tested for temperature stability, which means clarity, no precipitate, and no phase separation, at 4 C., at room temperature (RT), at 20 C. to 25 C., and at 40 C. to 42 C. Further, the air freshening compositions were tested for 3 cycles freeze-thaw stability. All experimental data described herein (Examples CO; FIGS. 1-12) were obtained as described herein and using the same type of electrical plug-in device comprising: (i) a 25 ml glass reservoir, into which the freshening composition is loaded, (ii) a delivery system, which comprises a 70 mm long and 0.8 mm diameter wick (one end of the wick being in direct contact with the freshening composition, while the other end of the wick is exposed to the external environment), and (iii) an electrical plug-in device, into which the reservoir with the attached wick is fitted. It is noted that the use of the electrical plug-in device as described herein, is not limiting. Other devices may be used in combination with the freshening composition of the present invention. 20 g of freshening composition were used, which contained the indicated wt % for each individual ingredient of a freshening composition. For example, a freshening composition comprising (i) a perfume raw material and (ii) a fragrance release modulator would comprise X wt % perfume raw material and Y wt % of an FRM, wherein, when no other component in the freshening composition is present, X+Y=100. Likewise, a freshening composition comprising (i) a perfume raw material, (ii) a solvent, and (iii) a fragrance release modulator would comprise X wt % of perfume raw material, Y wt % of an FRM, and Z wt % of solvent or diluent, wherein, when no other component in the freshening composition is present, X+Y+Z=100. Likewise, a freshening composition comprising (i) a perfume raw material, (ii) a fragrance release modulator, and (iii) a functional ingredient would comprise X wt % of perfume raw material, Y wt % of an FRM, and W wt % of a functional ingredient, wherein, when no other component in the freshening composition is present, X+Y+W=100. Likewise, a freshening composition comprising (i) a perfume raw material, (ii) a fragrance release modulator, (iii) a solvent, and (iv) a functional ingredient would comprise X wt % of perfume raw material, Y wt % of an FRM, Z wt % of a solvent, and W wt % of a functional ingredient, wherein, when no other component in the freshening composition is present, X+Y+Z+W=100)

    [0566] All measurements (Examples CO) were taken at room temperature. Percentage weight loss of the freshening composition (starting weight: 20 g) was determined on the days indicated in the figures (typically weekdays). The data presented herein consists of daily cumulative percentage released weight-loss, which is calculated as follows: [(initial weight of the entire freshening composition (which consists of the initial weight of the freshening composition+the weight of the reservoir+the weight of the wick+the weight of the electrical plug-in))(daily weight of the entire freshening composition (which consists of the weight of the freshening composition+the weight of the reservoir+the weight of the wick+the weight of the electrical plug-in))]/initial weight of the air freshening composition. Typically, the release profiles were analyzed for more than 3 weeks. Typically, by 7 days (sometimes earlier) it was clearly apparent if a tested FRM would up-regulate or down-regulate the release of the freshening composition or of a component thereof.

    [0567] In this Example, the influence of different solvents on the release and evaporation of a freshening composition comprising 50 wt % of the Apple Fragrance was examined. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of 50 wt % Apple Fragrance (see, Table 9, Example A) and 50 wt % solvents. The following solvents were tested: Augeo Clean Multi (acetone monoglycerol ketal; from Solvay), IPD-AC (3-methyl-1,3-butanediol-acetate; from Kuraray), STA-SOL ESS 165 (dimethyl adipate; from ST Laboratories, Inc.), and VOLASIL DM-2 (dimethiocone; from CHEMSIL Silicones, Inc.). Upon adding the freshening composition into a reservoir in an electrical plug-in device having a single wick, release and evaporation of the freshening composition was analyzed. Exemplary results are schematically depicted in FIG. 1.

    [0568] As schematically depicted in FIG. 1, the various solvents cause different release profiles of the Apple Fragrance. While the silicon solvent VOLASIL DM-2 (dimethiocone) leads to fast release of the freshening composition, the solvent Augeo Clean Multi (acetone monoglycerol ketal) results in a slower release profile. The solvents IPD-AC (3-methyl-1,3butanediol-acetate) and STA-SOL ESS 165 (dimethyl adipate) lead to intermediary release profiles.

    Example D. The Influence of Different Solvents on the Release and Evaporation of a Freshening Composition Comprising 50 Wt % Floral Fresh Fragrance

    [0569] In this Example, the influence of different solvents on the release and evaporation of a freshening composition comprising 50 wt % of the Floral Fresh Fragrance was examined. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of 50 wt % Floral Fresh Fragrance (see, Table 10, Example B) and 50 wt % solvents. The following solvents were tested: Augeo Clean Multi (acetone monoglycerol ketal; from Solvay), IPD-AC (3-methyl-1,3-butanediol-acetate; from Kuraray), STA-SOL ESS 165 (dimethyl adipate; from ST Laboratories, Inc.), and VOLASIL DM-2 (dimethiocone; from CHEMSIL Silicones, Inc.). Release and evaporation of the freshening composition was tested as described in Example C. Exemplary results are schematically depicted in FIG. 2.

    [0570] As schematically depicted in FIG. 2, the various solvents cause different release profiles of the Floral Fresh Fragrance. While the silicon solvent VOLASIL DM-2 (dimethiocone) leads to fast release of the freshening composition, the solvent Augeo Clean Multi (acetone monoglycerol ketal) results in a slower release profile. The solvents IPD-AC (3-methyl-1,3-butanediol-acetate) and STA-SOL ESS 165 (dimethyl adipate) lead to intermediary release profiles.

    Example E. The Influence of Different Fragrance Release Modulators (FRMs) on the Release and Evaporation of a Freshening Composition Comprising 50 Wt % Apple Fragrance and 42.5 Wt % of Solvent Augeo Clean Multi

    [0571] In this Example, the influence of various fragrance release modulators (FRMs) on the release and evaporation of a freshening composition comprising (i) 50 wt % of the Apple Fragrance (ii) 42.5 wt % of the solvent Augeo Clean Multi (acetone monoglycerol ketal) and (iii) 7.5 wt % of various FRMs was examined. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of 50 wt % Apple Fragrance (see, Table 9, Example A) 42.5 wt % solvent Augeo Clean Multi (acetone monoglycerol ketal), and 7.5 wt %, of the following Fragrance Release Modulators (FRMs): EtOH (ethanol), TEC (triethyl citrate), MMB (3-methyl-3-methoxyl butanol), BB (benzyl benzoate), and DPG (dipropylene glycol). The release and evaporation of the FRM-containing freshening compositions were compared to a control freshening composition not comprising an FRM, i.e., a freshening composition comprising 50 wt % of Apple Fragrance and 50 wt % of the solvent Augeo Clean Multi (acetone monoglycerol ketal). Release and evaporation of the freshening composition was tested as described in Example C. Exemplary results are schematically depicted in FIG. 3.

    [0572] As schematically depicted in FIG. 3, compared to the control freshening composition, each of the tested FRMs (TEC, BB, EtOH, MMB, and DPG) at 7.5 wt % in the freshening composition and in combination with the solvent Augeo Clean Multi (acetone monoglycerol ketal) leads to an up-regulation of release of the freshening composition or of a component thereof t the tested concentration, TEC is the strongest up-regulator FRM, followed by BB and EtOH. MMB and DPG, while still upregulating significantly, upregulate less than TEC, BB, and EtOH.

    Example F. The Influence of Different Fragrance Release Modulators (FRMs) on the Release and Evaporation of a Freshening Composition Comprising 50 Wt % Floral Fresh Fragrance and 42.5 Wt % of Solvent IPD-AC

    [0573] In this Example, the influence of various fragrance release modulators (FRMs) on the release and evaporation of a freshening composition comprising (i) 50 wt % of the Floral Fresh Fragrance (ii) 42.5 wt % of the solvent IPD-AC (3-methyl-1,3-butanediol-acetate) and (iii) 7.5 wt % of various FRMs was examined. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of 50 wt % Floral Fresh Fragrance (see, Table 10, Example B) 42.5 wt % solvent IPD-AC (3-methyl-1,3-butanediol-acetate) and 7.5 wt % of the following fragrance release modulators (FRMs): EtOH (ethanol), TEC (triethyl citrate), MMB (3-methyl-3-methoxyl butanol), BB (benzyl benzoate), and DPG (dipropylene glycol). The release and evaporation of the FRM-containing freshening compositions were compared to a control freshening composition not comprising an FRM, i.e., a freshening composition comprising 50 wt % of Floral Fresh Fragrance and 50 wt % of the solvent IPD-AC (3-methyl-1,3-butanediol-acetate). Release and evaporation of the freshening composition was tested as described in Example C. Exemplary results are schematically depicted in FIG. 4.

    [0574] As schematically depicted in FIG. 4, compared to the control freshening composition, the tested FRMs TEC and EtOH at 7.5 wt % in the freshening composition and in combination with the solvent IPD-AC (3-methyl-1,3-butanediol-acetate) lead to an up-regulation of release of the freshening composition or of a component thereof t the tested concentration and conditions, MBB, TEC and BB lead to a down-regulation of release of the freshening composition or component thereof.

    Example G. The Influence of Various Concentrations of Fragrance Release Modulator Benzyl Benzoate on the Release and Evaporation of a Freshening Composition Comprising 50 Wt % Apple Fragrance and Solvent Augeo Clean Multi

    [0575] In this Example, the influence of various concentrations of the fragrance release modulators benzyl benzoate (BB) on the release and evaporation of a freshening composition comprising (i) 50 wt % of the Apple Fragrance (ii) various wt % of the solvent Augeo Clean Multi (acetone monoglycerol ketal) and (iii) increasing wt % of BB was examined. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of 50 wt % Apple Fragrance (see, Table 9, Example A), various wt % solvent Augeo Clean Multi and various wt % of fragrance release modulator BB (benzyl benzoate). The following freshening compositions were formulated and tested: 50 wt % Apple Fragrance/50 wt % Augeo Clean Multi (control freshening composition not comprising an FRM); 50 wt % Apple Fragrance/42.5 wt % Augeo Clean Multi/7.5 wt % BB; 50 wt % Apple Fragrance/25 wt % Augeo Clean Multi/25 wt % BB; 50 wt % Apple Fragrance/7.5 wt % Augeo Clean Multi/42.5 wt % BB; and 50 wt % Apple Fragrance/50 wt % BB (freshening composition not comprising a solvent). Release and evaporation of the freshening compositions was tested as described in Example C. Exemplary results are schematically depicted in FIG. 5.

    [0576] As schematically depicted in FIG. 5, compared to a control freshening composition not comprising an FRM, depending on the concentration of the fragrance release modulator BB in the freshening composition, it either up-regulates or down-regulates the release of the freshening composition or of a component thereof. More specifically, when present at concentrations of 7.5 wt % and 25 wt % in the freshening composition, BB up-regulates the release of the freshening composition or of a component thereof. When present at concentrations of 42.5 wt % and 50 wt % in the freshening composition, BB down-regulates the release of the freshening composition or of a component thereof. BB is an FRM, which at low concentrations up-regulates the release of a freshening composition or component thereof and which, at higher concentrations, down-regulates such release. Thus, BB is a preferred FRM to customize, control and/or to modulate the release of a freshening composition or of a component thereof.

    Example H. The Influence of Various Concentrations of the Fragrance Release Modulator Benzyl Benzoate on the Release and Evaporation of a Freshening Composition Comprising 50 Wt % Floral Fresh Fragrance and Solvent IPD-AC

    [0577] In this Example, the influence of various concentrations of the fragrance release modulators benzyl benzoate (BB) on the release and evaporation of a freshening composition comprising (i) 50 wt % of the Floral Fresh Fragrance (ii) various wt % of the solvent IPD-AC (3-methyl-1,3-butanediol-acetate) and (iii) increasing wt % of BB was examined. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of 50 wt % Floral Fresh Fragrance (see, Table 10; Example B), various wt % solvent IPD-AC (3-methyl-1,3-butanediol-acetate) and various wt % of fragrance release modulator BB (benzyl benzoate). The following freshening compositions were formulated and tested: 50 wt % Floral Fresh Fragrance/50 wt % IPD-AC (control freshening composition not comprising an FRM); 50 wt % Floral Fresh Fragrance/42.5 wt % IPD-AC/7.5 wt % BB; 50 wt % Floral Fresh Fragrance/25 wt % IPD-AC/25 wt % BB; 50 wt % Floral Fresh Fragrance/7.5 wt % IPD-AC/42.5 wt % BB; and 50 wt % Floral Fresh Fragrance/50 wt % BB. Release and evaporation of the freshening compositions was tested as described in Example C. Exemplary results are schematically depicted in FIG. 6.

    [0578] As schematically depicted in FIG. 6, compared to a control freshening composition not comprising an FRM, the fragrance release modulator BB in the freshening composition, at the concentrations (wt %) tested, down-regulates the release of the freshening composition or of a component thereof. When present at concentrations of 7.5 wt %, 25 wt %, 42.5 wt %, and 50 wt % in the freshening composition, BB down-regulates the release of the freshening composition or of a component thereof. See also, Example G and FIG. 5. Thus, BB is a preferred FRM to customize, control and/or to modulate the release of a freshening composition or of a component thereof, specifically for use as a down-regulator and in combination with the solvent IPD-AC (3-methyl-1,3-butanediol-acetate).

    Example L the Influence of Various Solvents on the Release and Evaporation of a Freshening Composition Comprising Either 50 Wt % Apple Fragrance or 50 Wt % Floral Fresh Fragrance

    [0579] In this Example, the influence of various solvents on the release and evaporation of a freshening composition comprising either (i) 50 wt % of the Apple Fragrance or (ii) 50 wt % of the Floral Fresh Fragrance was examined. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of either 50 wt % Apple Fragrance (see, Table 9, Example A) or 50 wt % Floral Fresh Fragrance (see, Table 10, Example B) and 50 wt % of a solvent as indicated. The following freshening compositions were formulated and tested: 50 wt % Apple Fragrance/50 wt % Augeo Clean Multi; 50 wt % Apple Fragrance/50 wt % DMA; 50 wt % Apple Fragrance/50 wt % VOLASIL DM-2; 50 wt % Apple Fragrance/50 wt % IPD-AC; 50 wt % Floral Fresh Fragrance/50 wt % Augeo Clean Multi; 50 wt % Floral Fresh Fragrance/50 wt % DMA; 50 wt % Floral Fresh Fragrance/50 wt % VOLASIL DM-2; and 50 wt % Floral Fresh Fragrance/50 wt % IPD-AC. Release and evaporation of the freshening compositions was tested as described in Example C. Exemplary results are schematically depicted in FIG. 7.

    [0580] As schematically depicted in FIG. 7, each of the solvents depicted impacted the release profile of the freshening composition or of a component thereof. Of the four solvents tested, Augeo Clean Multi led to the slowest release profile and VOLASIL DM-2 to the fastest. IPD-AC and DMA lead to an intermediary release.

    [0581] The result depicted in FIG. 7 is somewhat similar to the results shown in FIGS. 1 and 2, respectively, however, emphasizes a different aspect. FIG. 7 schematically depicts the difference in release performance of the same product compositions (i.e., either Apple Fragrance or Floral Fresh Fragrance) due to the different type of solvent used. As schematically depicted in FIG. 7, air freshener products, regardless of the fragrance used, comprising the VOLASIL DM-2 solvent are the fastest ones to release the freshening composition, while the Augeo Clean Multi are the slowest ones to release the freshening compositions.

    Example J. The Influence of Solvents Augeo Clean Multi and IPD-AC on the Release and Evaporation of a Freshening Composition Comprising Either 50% Apple Fragrance or 50% Floral Fresh Fragrance

    [0582] In this Example, the influence of 50 wt % of solvents IPD-AC- and Augeo Clean Multi on the release and evaporation of a freshening composition comprising either (i) 50 wt % of the Apple Fragrance or (ii) 50 wt % of the Floral Fresh Fragrance was examined. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of either 50 wt % Apple Fragrance (see, Table 9, Example A) or 50 wt % Floral Fresh Fragrance (see, Table 10, Example B) and 50 wt % of a solvent as indicated. The following freshening compositions were formulated and tested: 50 wt % Apple Fragrance/50 wt % Augeo Clean Multi; 50 wt % Apple Fragrance/50 wt % IPD-AC; 50 wt % Floral Fresh Fragrance/50 wt % Augeo Clean Multi; and 50 wt % Floral Fresh Fragrance/50 wt % IPD-AC-Release and evaporation of the freshening compositions was tested as described in Example C. Exemplary results are schematically depicted in FIG. 8.

    [0583] The result schematically depicted in FIG. 8 emphasizes that different PRMs have a different release profile when combined with the solvents IPD-AC- or Augeo Clean Multi. The release profile of Floral Fresh Fragrance with either solvent IPD-AC- or Augeo Clean Multi is faster than that of Apple Fragrance with either solvent IPD-AC- or Augeo Clean Multi.

    Example K. The Influence of Different Fragrance Release Modulators (FRMs) on the Release and Evaporation of a Freshening Composition Comprising 50 Wt % Floral Fresh Fragrance and Solvent IPD-AC

    [0584] In this Example, the influence of increasing concentrations of the fragrance release modulators benzyl benzoate (BB) on the release and evaporation of a freshening composition comprising (i) 50 wt % of the Floral Fresh Fragrance (ii) various wt % of the solvent IPD-AC (3-methyl-1,3-butanediol-acetate) and (iii) increasing wt % of BB was examined. Further, the influence of three different FRMs at constant concentration was tested. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of 50 wt % Floral Fresh Fragrance (see, Table 10, Example B), various wt % of solvent IPD-AC and various wt % of a fragrance release modulator as indicated. The following freshening compositions were formulated and tested: 50 wt % Floral Fresh Fragrance/42.5 wt % IPD-AC/7.5 wt % MMB; 50 wt % Floral Fresh Fragrance/42.5 wt % IPD-AC/7.5 wt % BB; 50 wt % Floral Fresh Fragrance/42.5 wt % IPD-AC/7.5 wt % TEC; 50 wt % Floral Fresh Fragrance/42.5 wt % IPD-AC/7.5 wt % DPG; 50 wt % Floral Fresh Fragrance/25 wt % IPD-AC/25 wt % BB; 50 wt % Floral Fresh Fragrance/7.5 wt % IPD-AC/42.5 wt % BB; 50% Floral Fresh Fragrance/50 wt % IPD-AC (control freshening composition not comprising an FRM); 50% Floral Fresh Fragrance/50 wt % BB (freshening composition not comprising a solvent). Release and evaporation of the freshening compositions was tested as described in Example C. Exemplary results are schematically depicted in FIG. 9.

    [0585] As schematically depicted in FIG. 9, the different FRMs tested (DPG, MMB, TEC, and BB) lead to a different release profile. Of the FRMs tested, DPG lead to the fastest releaseat the tested concentration and in combination with the solvent IPD-AC and the Floral Fresh Fragrance. BB was led to the slowest release. As already tested in Example H, increasing the concentration of BB (from 7.5 wt % to 50 wt %) leads to a further down-regulation of release of the freshening composition or of a component thereof.

    Example L. The Influence of Different Fragrance Release Modulators (FRMs) on the Release and Evaporation of a Freshening Composition Comprising 50 Wt % Apple Fragrance, Solvent Augeo Clean Multi and Various Fragrance Release Modulators

    [0586] In this Example, the influence of increasing concentrations of the fragrance release modulators benzyl benzoate (BB) on the release and evaporation of a freshening composition comprising (i) 50 wt % of the Apple Fragrance (ii) various wt % of the solvent IPD-AC (3-methyl-1,3-butanediol-acetate) and (iii) increasing wt % of BB was examined. Further, the influence of three different FRMs at constant concentration was tested. Various freshening compositions were formulated and tested. Each freshening composition analyzed in this Example consisted of 50 wt % Apple Fragrance (see, Table 9, Example A), various wt % of solvent Augeo Clean Multi and various wt % of a fragrance release modulator as indicated. The following freshening compositions were formulated and tested: 50 wt % Apple Fragrance/50 wt % IPD-AC (control freshening composition not comprising an FRM); 50 wt % Apple Fragrance/50 wt % STA-SOL ESS 165 (control freshening composition not comprising an FRM); 50 wt % Apple Fragrance/42.5 wt % Augeo Clean Multi/7.5 wt % MMB; 50 wt % Apple Fragrance/42.5 wt % Augeo Clean Multi/7.5 wt % EtOH; 50 wt % Apple Fragrance/42.5 wt % Augeo Clean Multi/7.5 wt % BB; 50 wt % Apple Fragrance/42.5 wt % Augeo Clean Multi/7.5 wt % TEC; 50 wt % Apple Fragrance/42.5 wt % Augeo Clean Multi/7.5 wt % DPG; 50 wt % Apple Fragrance/25 wt % Augeo Clean Multi/25 wt % BB; 50 wt % Apple Fragrance/7.5 wt % Augeo Clean Multi/42.5 wt % BB; 50 wt % Apple Fragrance/50 wt % BB (freshening composition not comprising a solvent). Release and evaporation of the freshening compositions was tested as described in Example C. Exemplary results are schematically depicted in FIG. 10.

    [0587] As schematically depicted in FIG. 10, the different FRMs tested (DPG, TEC, BB, EtOH, and MMB) lead to a different release profile. Of the FRMs tested, DPG lead to the fastest releaseat the tested concentration and in combination with the solvent Augeo Clean Multi and the Apple Fragrance. As already tested in Example G, increasing the concentration of BB (from 7.5 wt % to 50 wt %) leads to a down-regulation of release of the freshening composition or of a component thereof.

    Example M. No Statistically Significant Modulation of Release of a Freshening Composition or of a Component Thereof without a Fragrance Release Modulator

    [0588] Various freshening compositions were formulated. As described herein, in some embodiments, a fragrance release modulator is an aryl-ether. However, not every aryl-ether functions as a fragrance release modulator. Eucalyptol, for example, is an aryl-ether. To test whether eucalyptol functions as an FRM, the following freshening compositions, comprising two different perfume raw materials were formulated and tested: Freshening composition #1: 50 wt % linalool (a perfume raw material), 45 wt % Augeo Clean Multi (a solvent) and 5 wt % eucalyptol (an aryl ether); Freshening composition #2: 50 wt % linalool (a perfume raw material), 50 wt % Augeo Clean Multi (a solvent) and 0 wt % eucalyptol (an aryl ether). Freshening composition #3: 50 wt % benzyl acetate (a perfume raw material), 45 wt % Augeo Clean Multi (a solvent) and 5 wt % eucalyptol (an aryl ether); Freshening composition #4: 50 wt % benzyl acetate (a perfume raw material), 50 wt % Augeo Clean Multi (a solvent) and 0 wt % eucalyptol (an aryl ether). As described in Example C, 20 g of each freshening composition were added into a device, and the total weight of freshening composition and device was taken at Day 0. Release of the freshening composition was determined (as described in Example C) by measuring on subsequent days the weight of the device including the remaining freshening composition in the device.

    [0589] Percentage release of the freshening compositions or of a component thereof was calculated as follows: First, total weight loss was determined by subtracting the total weight at any tested subsequent days from the total starting weight on Day 0. Percentage weight loss was then determined by dividing the evaporated amount (weight loss in g) by 20 g (the starting material of the freshening composition). The following results were obtained:

    TABLE-US-00011 TABLE 11 Release of a freshening composition. Data as measured for freshening composition #1 (Example M).

    [0590] One of ordinary skill in the art will appreciate that there is no statistically significant difference between the data obtained with Freshening Composition #1 (including eucalyptol) and Freshening Composition #2 (not including eucalyptol) with respect to the release of the freshening composition or of a component thereof s such, in combination with the perfume raw material linalool and the solvent Augeo Clean Multi, the ingredient eucalyptol does not function as a fragrance release modulator.

    [0592] One of ordinary skill in the art will appreciate that there is no statistically significant difference between the data obtained with Freshening Composition #3 (including eucalyptol) and Freshening Composition #4 (not including eucalyptol) with respect to the release of the freshening composition or of a component thereof s such, also in combination with another perfume raw material (benzyl acetate) and the solvent Augeo Clean Multi, the ingredient eucalyptol does not function as fragrance release modulator.

    [0593] To test a higher concentration of eucalyptol in the freshening compositions of above, the concentration of eucalyptol in Freshening Compositions #1 and #3 was increased to 12.5 wt % (in the presence of 37.5 wt % Augeo Clean Multi and 50 wt % of the same perfume raw materials). Even with a higher wt % of the ingredient eucalyptol, it did not function as a fragrance release modulator (data not shown).

    Example N. Influence of Various Fragrance Release Modulators on the Release of a Freshening Composition Comprising the Apple Fragrance and Fragrance Release Modulator Only

    [0594] In this Example the influence of various fragrance release modulators on the release of a freshening composition comprising only an FRM and a blend of perfume raw materials but no solvent was tested. The following freshening compositions were formulated and tested. Freshening composition #1: 50 wt % Apple Fragrance (a perfume raw material; see, Table 9, Example A) and 50 wt % dipropylene glycol (DPG, an FRM); Freshening composition #2: 50 wt % Apple Fragrance, and 50 wt % triethyl citrate (TEC, an FRM); Freshening composition #3: 50 wt % Apple Fragrance, and 50 wt % 3-methyl-3-methoxyl butanol (MMB, an FRM); Freshening composition #4: 50 wt % Apple Fragrance, and 50 wt % hexylene glycol (HG, an FRM); and Freshening composition #5: 100 wt % Apple Fragrance, (control freshening composition not comprising an FRM). As described in Example C, 20 g of each freshening composition were added into an electrical wall plug-in device, and the total weight of freshening composition and device was taken at Day 0. Release of the freshening composition was determined (as described in Example C) by measuring on subsequent days the weight of the device including the remaining freshening composition in the device.

    [0595] Percentage release of the freshening compositions or of a component thereof was calculated as follows: First, total weight loss was determined by subtracting the total weight at any tested subsequent days from the total starting weight on Day 0. Percentage weight loss was then determined by dividing the evaporated amount (weight loss in g) by 20 g (the starting material of the freshening composition). The following results were obtained:

    [0596] The data gathered from Tables 15-19 are schematically depicted in FIG. 11. The data demonstrate that, in the absence of a solvent or diluent, different fragrance release modulators lead to different release profiles of the freshening composition comprising the same blend of perfume raw materials (Apple Fragrance, Example A) and the respective fragrance release modulators. More specifically, among the tested fragrance release modulators, 3-methyl-3-methoxyl butanol (MMB) leads to the fastest up-regulation of release of the freshening composition or of a component thereof. Hexylene glycol (HG) can be considered a medium-strong up-regulator of release of the freshening composition or of a component thereof. Dipropylene glycol (DPG) can be considered a slow up-regulator of release of the freshening composition or of a component thereof. Triethyl citrate (TEC) can be considered a down-regulator of release of the freshening composition or of a component thereof.

    Example O. Influence of Various Fragrance Release Modulators on the Release of a Freshening Composition Comprising the Floral Fresh Fragrance and Fragrance Release Modulator Only

    [0597] In this Example the influence of various fragrance release modulators on the release of a freshening composition comprising only an FRM and a blend of perfume raw materials but no solvent was tested. The following freshening compositions were formulated and tested. Freshening composition #1: 50 wt % Floral Fresh Fragrance (a perfume raw material; see, Table 10, Example B) and 50 wt % dipropylene glycol (DPG, an FRM); Freshening composition #2: 50 wt % Floral Fresh Fragrance and 50 wt % triethyl citrate (TEC, an FRM); Freshening composition #3: 50 wt % Floral Fresh Fragrance and 50 wt % 3-methyl-3-methoxyl butanol (MMB, an FRM); Freshening composition #4: 50 wt % Floral Fresh Fragrance and 50 wt % hexylene glycol (HG, an FRM); and Freshening composition #5: 100 wt % Floral Fresh Fragrance (control freshening composition not comprising an FRM). As described in Example C, 20 g of each freshening composition were added into an electrical wall plug-in device, and the total weight of freshening composition and device was taken at Day 0. Release of the freshening composition was determined (as described in Example C) by measuring on subsequent days the weight of the device including the remaining freshening composition in the device.

    [0598] Percentage release of the freshening compositions or of a component thereof was calculated as follows: First, total weight loss was determined by subtracting the total weight at any tested subsequent days from the total starting weight on Day 0. Percentage weight loss was then determined by dividing the evaporated amount (weight loss in g) by 20 g (the starting material of the freshening composition). The following results were obtained:

    [0599] The data gathered from Tables 20-24 are schematically depicted in FIG. 12. The data demonstrate that, in the absence of a solvent or diluent, different fragrance release modulators lead to different release profiles of the freshening composition comprising the same blend of perfume raw materials (Floral Fresh Fragrance, Example B) and the respective fragrance release modulators. More specifically, among the tested fragrance release modulators, 3-methyl-3-methoxyl butanol (MMB) leads to the fastest up-regulation of release of the freshening composition or of a component thereof. Hexylene glycol (HG) can be considered a medium-strong up-regulator of release of the freshening composition or of a component thereof. Dipropylene glycol (DPG) can be considered a slow up-regulator of release of the freshening composition or of a component thereof. Triethyl citrate (TEC) can be considered a downregulator of release of the freshening composition or of a component thereof. The data obtained in Example N, using the Apple Fragrance, is very similar to the data obtained in Example O using the Floral Fresh Fragrance.
