Description

DETAILED DESCRIPTION OF THE INVENTION

[0016] In the following description and the claims appended hereto, it is to be understood that the terms used have their ordinary and accustomed meanings in the art, unless otherwise specified.

[0017] About as used herein means within 10% of the indicated number (e.g., about 10% means 9%-11% and about 2% means 1.8%-2.2%).

[0018] A or an as used herein means at least one.

[0019] At least one means one or more and thus includes individual components as well as mixtures/combinations.

[0020] As used herein, all ranges provided are meant to include every specific point and range within, and combination of subranges between, the given ranges. Thus, a range from 1-5 includes specifically the integers within the range 1, 2, 3, 4 and 5, as well as subranges such as and 2-5, 3-5, 2-3, 2-4, 1-4, etc., as well as all fractional numbers within the range such as 1.2, 2.3, 3.4, etc., and subranges including such fractional numbers such as 1.5-3.8, 2-4.3, 4.2-4.9, etc.

[0021] Mattity as used herein relates to minimal substantial specular reflection of a surface or material, including an absence of such specular reflection. Specular reflection is directly calculated from the ratio of incident light (the light that hits an object) to reflected light (the light that bounces off an object) and is the basis for standardizing and measuring gloss values. In determining quantitative values for mattity, an instrument called a Glossmeter can be used. The instrument projects a light on a surface at multiple incident angles and determines the amount of reflected light with detectors. The results are provided as gloss values, and are given in Gloss Units (GU), on a scale from 0 to 100, which is calibrated with a polished black surface equivalent to 100 GU, and 0 GU representing a perfectly matte surface. Optimally, the operator of the gloss meter would measure GU values at different incident angles of light for a given surface in order to determine the level of mattity or matte effect for the surface. A 20 incident angle is best used for high-gloss surfaces represented by 100-70 GU, a 60 incident angle is best used for semi-gloss represented by 70-10 GU, and an 85 incident angle is best used for matte represented by 10 GU or below.

[0022] Matte in compositions as used herein refers to compositions having little to no specular reflection. For example, matte compositions can have average gloss properties, measured at less than or equal to 10, for example 9, preferably less than or equal to 8, 6, 5, 4 or 1, including all ranges and subranges therebetween such as 1-10, 1-5, 2-10, 3-8, less than 1, less than 3, less than 5, etc.

[0023] To determine matte properties, films of compositions tested can be deposited onto BYK Clear Coated Paint Test Chart 2A using a 1 MIL drawdown bar and an Automatic Drawdown Machine. The films can then be dried at room temperature for 5 minutes, and then analyzed using a gloss meter (BYK: micro-TRI-gloss) at a desired angle, such as 85 for matte compositions.

[0024] Fluid composition as used herein refers a composition which is not solid at ambient temperature (25 C.) and for which it is possible to measure a viscosity. The term fluid is understood to mean a liquid composition which flows under its own weight at ambient temperature (25 C.) and atmospheric pressure. Advantageously, a fluid composition according to the present disclosure has a viscosity at 25 C. of less than 2000 mPa.Math.s.

[0025] According to preferred embodiments, the viscosity at 25 C. is less than 1000 mPa.Math.s, preferably less than 500 mPa.Math.s, and preferably less than 400 mPa.Math.s.

[0026] Soft Focus or Blurring as used herein refers to compositions which are able to blur or reduce the appearance of fine lines, wrinkles, or pores when applied to skin, typically through an optical effect of increasing diffusion of light.

[0027] Film former, film-forming polymer or film-forming agent as used herein means a polymer or resin which is capable of leaving a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, absorbed into and/or dissipated on the substrate.

[0028] Substituted as used herein, means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as hydrogen atoms or chlorine atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalky groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.

[0029] Volatile, as used herein, means having a flash point of less than about 115 C.

[0030] Non-volatile, as used herein, means having a flash point of greater than about 115 C.

[0031] Polymer as used herein means a compound which is made up of at least two monomers.

[0032] Free or substantially free or devoid of as it is used herein means that while it is preferred that no amount of the specific component be present in the composition, it is possible to have very small amounts of it in the compositions of the disclosure provided that these amounts do not materially affect at least one, preferably most, of the advantageous properties of the compositions of the disclosure. Thus, for example, free of oil means that an effective amount (that is, more than trace amounts) of oil(s) is/are omitted from the composition (that is, about 0% by weight), substantially free of oil means that oil(s) is/are present in amounts not greater than 0.1% by weight, and devoid of oil means that oil(s) is/are present in amounts not greater than 0.25% by weight, based on the total weight of the composition. The same nomenclature applies for all other ingredients identified throughout the application and in this paragraph such as, for example, specific UV filters and/or surfactants (compositions of the disclosure which are free of oxybenzone and/or octinoxate, substantially free of oxybenzone and/or octinoxate, and devoid of oxybenzone and/or octinoxate, as well as free of surfactants, substantially free of surfactants, and devoid of surfactants, have meanings consistent with the discussion within this paragraph), even if not specifically discussed for each identified ingredient in the application. Discussed examples of the use of such language such as those in this paragraph are intended to be exemplary, not limiting.

[0033] UV filters as it is used herein means sunscreen active agents approved by a governmental regulatory agency such as the Food and Drug Administration (FDA) in the U.S. or the EU Commission in Europe and includes organic UV filters such as avobenzone, octocrylene, benzophenones, benzotriazoles and merocyanines, as well as physical ultraviolet (UV)-attenuating materials.

[0034] Whitening or white cast as used herein refers to the visually white appearance of keratinous substance after a composition has been applied to the keratinous material as compared to the appearance of the keratinous material prior to application of the composition. A composition is non-whitening if it provides minimal or no visually white appearance (preferably no visually white appearance) to keratinous material upon application.

[0035] Anhydrous as it is used herein means that compositions of the disclosure contain less than 3% water, meaning that the compositions can also contain less than 2% water, and less than 1% water, as well as being free of water, substantially free of water, and devoid of water as defined above.

[0036] A UV absorbing system essentially containing at least one physical ultraviolet (UV)-attenuating material as it is used herein means that compositions of the disclosure contain less than 3% UV filters other than physical ultraviolet (UV)-attenuating material(s), in particular less than 3% of UV organic filters, meaning that within this definition as subcategories are compositions containing less than 2% UV filters other than physical ultraviolet (UV)-attenuating material(s), in particular less than 2% of UV organic filters, and less than 1% UV filters other than physical ultraviolet (UV)-attenuating material(s), in particular less than 1% of UV organic filters, as well as being free of UV filters other than physical ultraviolet (UV)-attenuating material, substantially free of UV filters other than physical ultraviolet (UV)-attenuating material, and devoid of UV filters other than physical ultraviolet (UV)-attenuating material as defined above.

[0042] Physiologically acceptable means compatible with keratinous materials and having a pleasant color, odor and feel, and which does not cause any unacceptable discomfort (stinging or tautness) liable to discourage a consumer from using the composition.

[0043] UV protection efficiency or filtering efficiency in the context of the present disclosure, is evaluated from one or more of SPF, UVAPF, Critical Wavelength, and UVA-I/UV ratio.

[0044] SPF (Sun Protection Factor) measures the level of protection against erythema provided by a composition. The SPF value corresponds to the ratio between the minimum erythemal dosage (MED) measured wearing the composition and the MED measured with bare skin. SPF is a known term in the sunscreen art and is defined, for example, in A new substrate to measure sunscreen protection factors throughout the ultraviolet spectrum, J. Soc. Cosmet. Chem., 40, 127-133 (May/June 1989).

[0045] The evaluation of the SPF (Sun Protection Factor) can be performed, for example, in vitro with spectrophotometer by Labsphere (North Sutton, NH, USA). In such an evaluation, the plate is the material on which the tested composition is applied. For such an evaluation, polymethylmethacrylate (PMMA) plates can be used. An example of an acceptable protocol is in the process of ISO accreditation under the name ISO Committee Draft 23675.

[0046] The evaluation of the Sun Protection Factor (SPF) can also be performed in-vivo according to the ISO 24444:2019 protocol Cosmetics-Sun protection test methods-In-vivo determination of the sun protection factor (SPF). Also, it can be determined according to FDA protocols, as described in the document Labeling and Effectiveness Testing; Sunscreen Drug Products for Over-the-Counter Human Use published in the US Federal Register on Jul. 5, 2011 (https://www.federalregister.gov/d/2011-14766); 21 C.F.R. Part 352 Subpart D 352.72, updated and revised by the 2011 publication in the Federal Register.

[0047] UVAPF (UVA protection factor) relates to an index characterizing the protection against UVA provided by a composition. For example, the UVAPF index can be measured in vivo according to the PPD (Persistent Pigment Darkening) method in the ISO-24442:2022 protocol, measuring observed skin color 2 to 4 hours after UVA exposure. Also, it can be determined according to FDA protocols, again as described in 21 C.F.R. Part 352 Subpart D 352.72 as discussed above in connection with SPF.

[0048] The evaluation of UVA protection can also be measured in vitro with the Labsphere spectrophotometer under conditions such as those discussed above in connection with SPF. ISO 24443:2021 protocol describes such an in vitro method.

[0049] FDA broad spectrum testing procedures, in particular critical wavelength testing procedures, can also be found at 21 C.F.R. Part 352 Subpart D 352.72. Also, broad spectrum testing procedures include determining the UVA1/UV ratio as described in Sunscreen Drug Products for Over-the-Counter Human Use published in the Federal Register https://www.federalregister.gov/documents/2019/02/26/2019-03019/sunscreen-drug-products-for-over-the-counter-human-use.

[0050] According to the present disclosure, compositions of the present disclosure preferably have one or more of the following properties: [0051] Compositions have a critical wavelength as determined by FDA's critical wavelength procedures of at least 370 nm; [0052] Compositions have an SPF value of at least 15, preferably at least 30, preferably at least 50 and preferably at least 70; [0053] Compositions have a UVAPF/SPF ratio of at least 1/3, and preferably at least 2/5; and/or [0054] Compositions have a UVA1/UV ratio of 0.7 or higher, preferably 0.75 or higher, and preferably 0.8 or higher.

[0055] Makeup Result as used herein, refers to compositions where color remains the same or substantially the same as at the time of application, as viewed by the naked eye, after an extended period of time. Makeup Result may be evaluated by evaluating long wear properties by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to keratinous material such as skin and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately following application to keratinous material such as skin and these characteristics may then be re-evaluated and compared after a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.

[0056] Natural as in the phrase natural compound refers to any compound derived directly from a natural substance such as a plant without having undergone any chemical modification.

[0057] Compound of natural origin refers to any compound derived from a natural compound which has undergone one or more chemical modifications, for example by organic synthesis reaction, without the properties of the natural compound having been modified.

[0058] Synthetic compound refers to any compound which is not a natural compound or a compound of natural origin.

[0059] Room temperature means about 20-25 C.

[0060] Atmospheric pressure means about 760 mmHg, i.e. about 105 pascals.

[0061] UV filter and sunscreen agent are used interchangeably in this application.

[0062] UV efficacy and UV efficiency and UV protection efficacy are used interchangeably in this application.

[0063] The compositions and methods of the present disclosure can comprise, consist of, or consist essentially of the essential elements and limitations of the disclosure described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful. For example, the UV (ultraviolet) absorbing system of the compositions of the disclosure can consist essentially of at least one physical ultraviolet (UV)-attenuating material(s).

[0064] For purposes of the present disclosure, the basic and novel property associated with compositions, components and methods related to properties which consist essentially of identified ingredients or actions is mattity.

[0065] Compositions of the present disclosure may be in any form suitable for use as a personal care composition, such as that of a stick, a paste, a cream, a liquid, a solid, etc. These compositions can be used for any personal care purpose in cosmetic and/or dermatological products such as, for example, a sunscreen, a foundation, lip balms, lipsticks, concealers, mascaras, leave-in hair products, eye shadows, powders, etc.

[0066] Referred to herein are trade names for materials including, but not limited to, materials such as polymers and optional components. Materials are not intended to be limited by materials described and referenced by a certain trade name herein. Equivalent materials (e.g., those obtained from a different source under a different name or catalog (reference) number) to those referenced by trade name may be substituted and utilized in the methods described and claimed herein.

[0067] All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total weight of a composition unless otherwise indicated. All component or composition levels are in reference to the active level of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources.

[0131] According to preferred embodiments, substantially spherical particulate material is in the form of microbeads. Microbeads as used herein refers to solid or porous particles, i.e. microparticles rather than microcapsules, having a circularity parameter of at least 0.95. The circularity parameter is defined as the ratio of the circumference of a disc having the same area as the particle to the perimeter of the particle. A value of 1 characterizes particles that are perfectly spherical.

[0132] Suitable microbeads are such that at least 90%, in numerical terms, have a diameter of less than or equal to 15 m preferably less than or equal to 10 m, preferably between 0.1 and 10 m and preferably between 0.5 and 10 m. Particle size distribution may be measured using an FPIA 2100 image analysis granulometer from the company Malvem.

[0133] Amorphous particulate materials have no required shape, except that they are not substantially spherical. Accordingly, amorphous particulate materials may be in lamellar (or platelet) form, fiber form, or in any other form which is not substantially spherical.

[0134] Lamellar particulate materials include particles of parallelepipedal shape (rectangular or square surface), discoid shape (circular surface) and/or ellipsoid shape (oval surface), characterized by three dimensions: a length, a width and a height.

[0143] With particular reference to substantially spherical particles, suitable examples of substantially spherical particles include certain silica aerogels. Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. They are generally synthesized via a sol-gel process in liquid medium and then dried, usually by extraction of a supercritical fluid, the one most commonly used being supercritical CO.sub.2. This type of drying makes it possible to avoid shrinkage of the pores and of the material. The sol-gel process and the various drying processes are described in detail in Brinker C J., and Scherer G. W., Sol-Gel Science: New York: Academic Press, 1990. Silica aerogels, in general, have been disclosed in U.S. Pat. No. 9,320,689, the entire contents of which is hereby incorporated by reference. Preferably, suitable silica aerogels have an average particle size less than about 20 microns.

[0144] Preferably, suitable silica aerogels include hydrophobic silica aerogels. Hydrophobic silica refers to whose surface is treated with a hydrophobic material such as silylating agents, for example halogenated silanes such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with silyl groups SiRn, for example trimethylsilyl groups. Hydrophobic silica aerogels particles surface-modified with trimethylsilyl groups (trimethylsilyl silica) are preferred. The preparation of hydrophobic silica aerogel particles that have been surface-modified by silylation, (silica silylate) can be found, for example in U.S. Pat. No. 7,470,725, the entire contents of which is hereby incorporated by reference. Suitable examples of substantially spherical silica aerogels having an average particle size less than about 20 microns include AIRLICA TL-10 from Tokuyama Corporation or CAB-O-SIL TS-530 from Cabot Corporation.

[0145] Other suitable examples of substantially spherical particulate materials include, but are not limited to, silicas, glass and polymers. Preferably, such substantially spherical particulate materials have an average particle size less than about 20 microns. Specific examples of such particulate materials may, for example be other spherical silicas such as Silica Balloon BA4 available from JGC Catalysts and Chemicals, which has an oil absorption 40 mL/100-gram powder and an average particle size of about 4 m. Other microspheres (beads) made from glass or polymers are also suitable particulate materials.

[0146] Discussed examples above with respect to substantially spherical particular matter may also provide suitable material for the at least one amorphous particulate matter. For example, the at least one amorphous particulate matter can be silica silylate. Accordingly, in preferred embodiments, the at least one substantially spherical particulate matter is silica silylate and the at least one amorphous particulate matter is also silica silylate.

[0147] Preferably, at least 50% by weight of the particulate materials in the particulate portion are substantially spherical, preferably at least 60% by weight, and preferably at least 70% by weight, preferably at least 75% by weight, and preferably at least 80% by weight, with all weights being based on the weight of the total particulate portion. Accordingly, preferably the particulate portion comprises a majority fraction of substantially spherical particulates, preferably having an average particle size less than about 20 microns.

[0148] Preferably, the at least one substantially spherical particulate material and at least one amorphous particulate material are present in the compositions of the present disclosure in a combined amount ranging from about 0.05% to about 10% by weight, preferably from 0.1% to 5% by weight, preferably from 0.25% to 4% by weight, and preferably from 0.5% to 3% by weight with respect to the total weight of the composition, including all ranges and subranges therebetween, such as, for example, 1% to 6%, 2% to 7.5% and 3% to 8%.

[0263] Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term about. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure.

[0264] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective measurements. The following examples are intended to illustrate the disclosure without limiting the scope as a result. The percentages are given on a weight basis.

Example 1

[0265] The following simplex oil dispersion mixtures were prepared and then measured for gloss by the following protocol: Films of compositions tested were deposited onto BYK Clear Coated Paint Test Chart 2A using a 1 MIL drawdown bar and an Automatic Drawdown Machine. The films were dried at room temperature for 5 minutes and analyzed using a gloss meter (BYK: micro-TRI-gloss) at an angle of 85.

[0266] These results indicate that while the addition of spherical and amorphous particulate matter individually result in some reduction of gloss (see comparative examples 2 and 3), the combination of both at least one spherical particulate and at least one amorphous particulate unexpectedly resulted in a dispersion having matte properties, characterized by gloss unit measurements at 85 less than 10GU (Inventive Example 1 compared to Comparative Example 1).

Example 2

[0267] The following compositions were prepared and then measured using the same protocol for gloss described in Example 1.

[0268] These results indicate that the spherical particles alone had substantial reduction of gloss in the compositions tested containing zinc oxide and titanium oxide (Comparative Example 5 compared to Comparative Example 4), however the combination of the spherical and amorphous particulate matters unexpectedly resulted in a composition having very low semi-gloss and near matte properties characterized by gloss unit measurements at 85 less than 15GU (Inventive Example 2 compared to Comparative Example 4).

[0270] These results indicate that spherical particles alone had reduction of gloss in the compositions tested containing zinc oxide (Comparative Example 7 compared to Comparative Example 6), however the combination of spherical particles and amorphous particles unexpectedly resulted in a composition having matte properties characterized by gloss unit measurements at 85 less than 10GU (Inventive Example 3 compared to Comparative Example 6).
