Abstract: An aqueous aerosol hair styling aid or mousse composition and method including a terpolymer of vinylpyrrolidone/ ethyl methacrylate/methacrylic acid (at least partially neutralized 30-100%) monomers in an amount of about 2% to about 20% by weight of the composition, particularly about 2% to about 15% by weight of the composition; water in an amount of about 20% to about 80% by weight of the composition; and a dimethyl ether liquified propellant gas in an amount of about 5% to about 50% based on the total weight of the aerosol composition.

Description: FIELD OF THE INVENTION The present invention is directed to an aerosol hair styling aid that is sprayed onto the hair from an aerosol composition, containing a dimethyl ether propellant, to provide the hair with a particular shape or configuration. More particularly, the present invention is directed to an aerosol hair styling aid including dimethyl ether as the propellant. A terpolymer of vinyl pyrrolidone, ethyl methacrylate and methacrylic acid (at least partially neutralized) monomers that has a very low percentage of volatile organic compounds and a high percentage of water and is capable of homogeneously dispersing a relatively high percentage of the terpolymer, with or without a water evaporation agent, such as an alcohol, for example, ethanol. BACKGROUND OF THE INVENTION AND PRIOR ART Hair sprays provide human hair with a particular shape or configuration and function by applying a thin film of a resin or gum onto the hair to adhere adjacent hairs together so that they retain the particular shape or configuration at the time of application. Many of these hair sprays have been applied from aerosol compositions that include a liquifiable propellant gas - generally a halohydrocarbon, such as trichlorofluoromethane or trichlorotrifluoroethane or a gaseous hydrocarbon such as propane or butane. Recently proposed legislation directed to the depletion of the atmospheric ozone layer has led to the halohydrocarbons being increasingly replaced with pure gaseous non-halogenated hydrocarbons as propellants. However, the use of non-halogenated hydrocarbons as propellants has resulted in a problem of decreased solubility of the hair spray resin or gum in water requiring an increased amount of volatile organic solvent, such as ethanol, to achieve sufficient solubility, therefore creating an additional ecological problem. As set forth in the Nuber et al Patent No. 4,767,613, a film-forming terpolymer of vinyl-pyrrolidone, t-butyl methacrylate and methacrylic acid monomers can be at least partially neutralized to improve the water solubility or dispersibility of the resin and provide the resin with the quality of being easier to remove from the hair during washing. However, as disclosed in the Nuber et al Patent No. 4,767,613, such aerosol hair treating agents generally have a maximum of about 5% water and require a high amount, up to about 95% by weight, of a volatile organic solvent, such as alcohol, despite the increased solubility of the neutralized resin. As stated in the product literature of Stepan Company, of Northfield, Illinois, directed to the use of the terpolymer of vinylpyrrolidone/ethyl methacrylate/methacrylic acid (STEPANHOLD EXTRA) for use as a fixative hair spray, this particular fixative polymer was designed specifically for pump sprays, not aerosol hair sprays. The terpolymer apparently was not found to be compatible with hydrocarbon propellants, or required far too much alcohol solvent to satisfy volatile organic contaminant regulations. Surprisingly, in accordance with the present invention, it has been found that excellent delivery of the terpolymer can be achieved with the use of dimethyl ether as the propellant. Stepan Company discloses one example of an aerosol hair spray that includes the terpolymer of the composition of the present invention and has 41.10% by weight water, but the composition also includes 45.70% by weight alcohol, as follows, where percentages are percent by weight: Terpolymer of polyvinyl pyrrolidone, ethylmethacylate, and methacrylic acid 9.60%; SDA 40 Alcohol (190 Proof) 45.70%; AMP (Regular) 0.40%; Silicone L-722 (Union Carbide) 0.50%; Propylene Glycol 2.00%; Perfume V-5177 (Van Dyke) 0.60%; 5% Morpholine in SDA 40 Alcohol 0.10%; and Distilled Water 41.10%. In accordance with the present invention, a new and improved aerosol hair styling aid composition has been found wherein a terpolymer of vinyl pyrrolidone/ethylmethacrylate/methacrylic acid - at least partially neutralized for water solubility; and 25% to 50% dimethyl ether propellant; can be suitably solubilized or dispersed in the aerosol composition containing 30% to 80% water and less than 40% volatile organic compounds (such as alcohol solvents and/or propellants), particularly less than about 35% volatile organic compounds (excluding the propellant), e.g., 0-30% ethanol, preferably 5-25% alcohol, while providing an aerosol styling aid or mousse that can effectively solubilize or disperse up to about 40% by weight of the composition of the terpolymer with a volatile organic compound, e.g., alcohol, being optionally included for faster drying. SUMMARY OF THE INVENTION In brief, the present invention is directed to an aqueous aerosol hair styling aid or mousse composition and method including a terpolymer of vinylpyrrolidone/ ethyl methacrylate/methacrylic acid (at least partially neutralized 30-100%) monomers in an amount of 1.0% to 15% by weight of the composition; water in an amount of 20% to 80% by weight of the composition; and a dimethyl ether liquified propellant gas in an amount of 25% to 50% based on the total weight of the aerosol composition. To achieve the full advantage of the present invention, the methacrylic acid monomer of the terpolymer should be neutralized 30% to 100% by weight. Accordingly, one aspect of the present invention is to provide a new and improved aerosol hair treating composition, and method, that can be applied to the hair from an aqueous aerosol composition in the form of a hair spray, mousse, foam or gel that provides hair setting compositions for retaining a particular shape or configuration of the hair. Another aspect of the present invention is to provide an aerosol hair styling aid composition, and method, in the form of a hair spray, mousse, foam or gel that includes water in an amount of 30% to 90% by weight of the composition, a fixative resin that is solubilized or dispersed in an amount of 2% to 40% by weight of the composition, and a propellant gas. Another aspect of the present invention is to provide an aerosol hair styling aid composition, and method, in the form of a hair spray, mousse, foam or gel, that includes at least 30% by weight water, a fixative resin comprising a terpolymer of vinyl pyrrolidone/ethyl methacrylate/methacrylic acid and a dimethyl ether propellant. Still another aspect of the present invention is to provide a new and improved aerosol hair styling aid composition, and method, that includes water in an amount of 30% to 90% by weight of the composition, a fixative resin that is solubilized or dispersed in an amount of 2% to 40% by weight of the composition, alcohol in an amount of 0-30%, preferably 5-25%, by weight, dimethyl ether propellant gas, and a conditioning agent in an amount of about 0.1% to about 10% by weight of the composition. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The aerosol hair styling aid composition of the present invention include 1.0% to 15% by weight of a terpolymer of vinyl pyrrolidone/ethyl methacrylate/methacrylic acid - at least partially neutralized for water solubility; and 25% to 50% dimethyl ether propellant; solubilized or dispersed in 30% to 80% water and less than 40% volatile organic compounds (e.g., alcohol solvent and/or propellant), particularly less than about 35% alcohol, e.g., 0-30% ethanol, preferably 5-25% alcohol. Surprisingly, the composition provides an aerosol styling aid or mousse that can effectively solubilize or disperse up to about 40% by weight of the composition of the terpolymer with a volatile organic compound, e.g., alcohol, being optionally included for faster drying. Mixtures of the vinyl pyrrolidone/ethyl methacrylate/methacrylic acid terpolymer with other polymers also may be used provided that the terpolymer is present in an amount of at least 50%, preferably at least 75% by weight of total fixative resin in the aerosol composition. With certain of the polymers, it may be necessary to neutralize some acidic groups to promote solubility/dispersibility, e.g., PVA/crotonic acid. Neutralization and increased solubilization are accomplished with one or more inorganic bases such as sodium hydroxide, potassium hydroxide, ammonium hydroxyde and/or ammonium carbonate. Among stable organic bases are the water soluble bases such as monoethanol amine (MEA), diethanol amine (DEA), triethanol amine (TEA), 2-methyl-2-amino-1-propanol (AMP), mono amino glycols, and the like, which help solubilize the polymer in water solutions. The terpolymer of the composition and method of the present invention is sufficiently soluble at about 60% neutralization without the inclusion of an alcohol solvent and at about 30% neutralization when at least about 5% alcohol, e.g., ethanol is included in the composition. The terpolymer can be sufficiently neutralized using .2% to 5% by weight of a base, based on the total weight of the aerosol composition. The pH of these solutions usually ranges from 5 to 12. Neutral pH's of 6 to 9 are preferred. The terpolymer, and optionally other combined fixative resins, is used at a level of from 1.0% to 15% of the total composition. The weight average molecular weight of the terpolymer is not critical but is generally in the range of from 2,000 to 2,000,000. In accordance with one important embodiment of the present invention, the composition of the present invention also includes from 0.1 to 10%, particularly 0.5% to 10%, and preferably from 1.0% to 5.0%, by weight of a non-volatile silicone compound or other conditioning agent(s), preferably a water-insoluble, emulsifiable conditioning agent. The preferred non-volatile silicone compound is a polydimethylsiloxane compound, such as a mixture, in about a 3:1 weight ratio, of a low molecular weight polydimethysiloxane fluid and a higher molecular weight polydimethylsiloxane gum. The non-volatile polydimethylsiloxane compound is added to the composition of the present invention in an amount sufficient to provide improved combing and improved feel (softness) to the hair after shampooing. As referred to herein, "silicone gums" are those nonfunctional siloxanes having a viscosity of from 5 to 600,000 mm²/s (centistokes) at 25°C. The so-called rigid silicones, as described in U.S. Patent No. 4,902,499, having a viscosity above 600,000 mm²/s (centistokes) at 20°C, e.g., 700,000 mm²/s (centistokes) plus, and a weight average molecular weight of at least about 500,000 also are useful in accordance with the present invention. Preferred silicone gums include linear and branched polydimethyl siloxanes, of the following general formula: (CH₃)₃SiO--[Si(CH₃)₂O] n --Si(CH₃)₃ , wherein n is from 2,000 to 15,000, preferably from 2,000 to 7,000. Silicone gums useful in compositions of the present invention are available from a variety of commercial sources, including General Electric Company and Dow Corning. Another particularly suitable conditioning agent that can be included in the composition of the present invention is a volatile hydrocarbon, such as a hydrocarbon including from 10 carbon atoms to 30 carbon atoms, that has sufficient volatility to slowly volatilize from the hair after application of the aerosol styling aid composition. The volatile hydrocarbons provide essentially the same benefits as the silicone conditioning agents. The preferred volatile hydrocarbon compound is an aliphatic hydrocarbon including from 12 to 24 carbon atoms, and having a boiling point in the range of from 100°C to 300°C. Exemplary volatile hydrocarbons are depicted in general structural formula (I), wherein n ranges from 2 to 5, Examples of volatile hydrocarbons useful in the composition of the present invention are the commercially-available compounds PERMETHYL 99A and PERMETHYL 101A, corresponding to compounds of general structure (I) wherein n is 2 and 3, respectively, available from Permethyl Corporation, Frazer, PA.

When present, such stabilizers comprise from 0.05% to 1%, preferably from 0.1% to 0.8%. The amount of the dimethyl ether propellant gas used in the composition and method of the present invention is governed by normal factors well known in the aerosol art. For mousses, the level of propellant is generally about 30% of the total composition. If the dimethyl ether propellent includes a vapor pressure suppressant (e.g., trichlorethane or dichloromethane), for weight percentage calculations, the amount of suppressant is included as part of the propellant. The aerosol compositions also can contain a variety of other nonessential, optional components suitable for rendering such compositions more acceptable. Such conventional optional ingredients are well known to those skilled in the art, e.g., other emulsifiers such as anionics (e.g., sodium alkyl sulfate); preservatives such as benzyl alcohol, methyl paraben, propyl paraben and imidazolidinylurea; catonic emulsifiers/conditioners such as cetyl trimethyl ammonium chloride, stearyldimethyl benzyl ammonium chloride, and di(partially) hydrogenated tallow, dimethylammonium chloride; thickeners and viscosity modifiers such as a diethanolamide of a long chain fatty acid, fatty alcohols (i.e., cetearyl alcohol), sodium chloride, sodium sulfate, and ethyl alcohol; pH adjusting agents such as citric acid, succinic acid, sodium hydroxide and triethanolamine; coloring agents such as any of the FD&C or D&C dyes; hair oxidizing (bleaching) agents such as hydrogen peroxide, perborate salts and persulfate salts; hair reducing agents such as thioglycolates; perfume oils; chelating agents such as ethylenediamine tetracetic acid; and, among many other agents, polymer plasticizing agents such as glycerin and propylene glycol. These optional materials are generally used individually at a level of from 0.01% to 19%, preferably from 0.5% to 5% by weight of the total composition. The aqueous formulations of the present invention also can contain the conventional hair spray adjuvants in amounts which generally range from about 0.1 to 2% by weight and preferably about 0.75 to 1% by weight. Among the additives which can be used are plasticizers such as glycols, pthalate esters and glycerine; silicones; emollients; lubricants and penetrants such as various lanolin compounds; protein hydrolysates and other protein derivatives; ethylene adducts and polyoxyethylene cholesterol; dyes, tints and other colorants; and perfumes. The optional alcohol employed in the composition is an aliphatic straight or branched chain monohydric alcohol having 2 to 4 carbon atoms. Isopropanol and especially ethanol are preferred. The concentration of the alcohol in the composition should be less than about 40% by weight, and surprisingly can be as low as 0%, preferably 0.1 to 30% by weight and more preferably 5 to 20% by weight. Some alcohol, in an amount of 2% to 25% by weight provides faster drying of the styling aid after application to the hair.
