Description

DESCRIPTION OF THE INVENTION

[0031] The present invention relates to a biodegradable aqueous composition based on natural extracts (natural essences and essential oils), quaternary ammonium, propylene glycol, Cellocize, EDTA, Tween 80, boric acid, aromas, colorants and water, for cleaning, disinfection as an antiseptic and which possesses broad-spectrum bactericidal activity, ie bactericidal at once on gram positive and gram negative bacteria; also as an insecticide or at least as an insect repellent, and as a freshener.

[0032] According to the present invention there is formulated a composition having properties for cleaning, disinfection, insecticide or repellent and as a freshener, based on natural essences, particularly those present in mint and clove essential oils, combined with acid boron, quaternary ammonium, and other products to facilitate their combination or mixing and cleaning surfaces. Propylene glycol is used as a stabilizer, solvent for chemicals, dyes and aromas; particularly, it is used in liquid detergents in support of hygienic conditions. Cellocize is used as a thickening agent. Ethylene diamine tetraacetic acid, also called EDTA or less commonly AEDT, is a substance that is used as a chelating agent to create complexes with heavy metal ions. TWEEN 80 which is a Nonionic surfactant or surfactant, also known as Polysorbate 80 N.F., or Polyoxyethylene Sorbitan Monooleate 80.

[0033] Finally, water is added in the amount necessary and sufficient to obtain an aqueous composition of the invention.

[0034] Throughout this specification and the appended claims, the percentages by weight of any constituent should be understood as the percentage by weight of the active portion of the referred constituent, unless otherwise indicated.

[0035] The compounds used in the formulation of the composition of the present invention will now be briefly described.

[0036] a) Essential Oils

[0037] 1. Peppermint oil is known for its effects as a bactericide and as an antiseptic. There is no exact composition formula since the percentage of each component may vary depending on the conditions of culture and collection of the plant as well as the extraction or distillation process. The main substances that we can find in essential oil of mint and its proportions are: [0038] Menthol with 30-55%; [0039] Mentone 14-32%; [0040] Methyl acetate 2.8-10%; [0041] Isomentone 1.5-10%; [0042] Mentofuran: 1-9%; [0043] Cineol: 3.5-14%; [0044] Limonene: 1-5%; [0045] Isopulegol: up to 0.2%; and [0046] Carvone: up to 1%.

[0047] 2. Among the main active compounds of clove essential oils are: [0048] Eugenol; [0049] Acetilenglenol; [0050] Caryophyllene; [0051] Pinenools entone; [0052] Caryophylline Menthyl; [0053] Icilato methyl; [0054] Tannins; [0055] Mucilages; [0056] Phytosterols; and [0057] Entrofuran.

[0058] b) Quaternary Ammonium

[0059] Quaternary ammonium compounds represent a family of antimicrobial compounds, which are considered to be potent cationic active agents in their disinfecting activity, since they are active to eliminate gram-negative and gram-negative bacteria, although the latter to a lesser degree are bactericidal, fungicidal and virucidal. Its activity is developed on both the acid and alkaline medium, although in the latter, better actions are compatible with cationic, nonionic and amphoteric actives. They are generally colorless or yellowish, non-irritating and deodorant. Due to their chemical structure at low temperatures they tend to “freeze” but recover their liquid state by warming them. They also have a detergent action and are soluble in water and alcohol. They have as basic structure the ammonium ion (NH4), which when modified, gives rise to different generations. Second-generation quaternary ammonium compounds (ethylbenzyl chloride) and third generation (first and second generation ie Benzalkonium Chloride and Alkyl Dimethyl Ethyl Benzyl Ammonium Chloride) compounds are compounds that remain most active in the presence of water hard.

[0060] Its bactericidal action is attributed to inactivation of enzymes, denaturation of essential proteins and the breakdown of the cell membrane. They are usually considered as disinfectants at concentrations of 0.25% to 1.6% for the disinfection of surfaces such as floors and walls. The third generation quaternaries have an increase in biocidal activity, increased detergency and an increase in bacterial resistance to the constant use of a single molecule. Fourth-generation quaternary ammonium compounds called quaternary “Twin or Dual Chain Quats” are quaternary products with linear dialkyl chains and without benzene ring, such as: Didexyl Dimethyl Ammonium Chloride or Dioctyl Dimethyl Ammonium Chloride or Octyl Decil Ammonium Chloride, each isolated. These quaternaries are superior in how much germicidal activity; they are of low foam and have a high tolerance to the loads of protein and the hard water.

[0061] They are recommended for disinfection in the food and beverage industry, as they can be applied due to their low toxicity. Finally, the fifth generation quaternary ammonium compounds are fourth generation blends with the second generation, ie: didecyl dimethyl ammonium chloride+alkyl dimethyl benzyl ammonium chloride+alkyl dimethyl ethyl benzyl ammonium chloride + . . . other varieties According to the formulations. The fifth generation has a higher germicidal performance under hostile conditions and is safe to use.

[0062] c) Propylene Glicol

[0063] Propylene glycol (propane-1,2-diol) is an organic compound (an alcohol, more precisely a diol) that is obtained by hydration of the propylene oxide. Propylene Glycol is a clear oily liquid, slightly viscous at room temperature, hygroscopic, colorless, tasteless and odorless, and miscible with water, acetone, and chloroform. Propylene Glycol has had an unparalleled reputation for safe use in a wide range of consumer products, including food products, animal feed, cosmetics and pharmaceuticals, as well as in industrial applications. It is used as a stabilizer, solvent in chemicals, dyes and aromas. Particularly, it is used in liquid detergents in support of hygienic conditions.

[0064] d) Cellosize

[0065] Cellocize is a compound that is used as a thickening agent that when added to a mixture increases its viscosity without substantially modifying its other properties such as freshener, etc. Provides body, increases stability and facilitates the formation of suspensions.

[0066] e) EDTA

[0067] Ethylene diamine tetraacetic acid, also called EDTA or less commonly AEDT, is a substance used as a chelating agent that can create complexes with heavy metal ions.

[0068] f) TWEEN 80

[0069] It is a non-ionic surfactant or surfactant, also known as polysorbate 80 NF, or polyoxyethylene sorbitan monooleate 80. It is a yellow to amber liquid, used for emulsification of oil in water (O/W), dispersion or solubilization Of oils, and to make anhydrous ointments washable. Tween 80 is often combined with SPAN 80 surfactant to promote emulsion stability.

[0070] g) Boric Acid

[0071] Boric acid was first recorded in the USA as insecticide in 1948 for the control of cockroaches, termites, ants, fleas, silverfish, and many other insects. The product is generally considered safe for use in home kitchens to control cockroaches and ants. It acts as a stomach poison that affects the metabolism of insects, and dry powder is abrasive to the exoskeleton of insects.

[0072] The invention provides a biodegradable aqueous composition based on natural extracts (natural essences and essential oils), quaternary ammonium, propylene glycol, Cellocize, EDTA, Tween 80, boric acid, aroma, colorants and water, which provides a cleaning benefit, a benefit of disinfectant, an insecticide or repellent and a freshener consisting of the following constituents:
