Description

COSMETIC COMPOSITION CONTAINING AN ANIONIC POLYMER AND A ACRILICO TERPOLIMERO AND USE OF THIS COMPOSITION FOR THE TREATMENT OF KERATINIC MATTERS Description of the invention The present invention relates to cosmetic compositions containing in association at least one anionic polymer and an acrylic terpolymer, as well as the use of these compositions for the treatment of keratin materials, in particular the skin and hair. ~~ The anionic polymers are generally used for their binding properties, in particular for the formulation of combing hair gels or head and fixation gels. It is interesting to formulate hair care compositions that contain anionic polymers having a high viscosity and are in the form of well-extending gels for care and combing. For this, thickener and / or gelling polymers have generally been used. However, the introduction of anionic polymers in the thickeners frequently leads to problems of fluidization and loss of limpidity and the cosmetic performances obtained are insufficient for the care and combing products. Thickening and / or gelling polymers are known which comprise in their chain a part REF .: 30468 hydrophilic and a hydrophobic part consisting of a fatty chain such as the product * PEMULEN TR1"marketed by the company GOODRICH or the polymers" CRYSOL "marketed by the company ROHM & HAAS. The polymer ^ PEMULEN TR1"used in association with anionic polymers does not lead to a gel of sufficient texture and does not give satisfactory results in the cosmetic plane, in particular as regards fixation power, softness and touch. * CRYSOL polymer 44"used in association with an anionic polymer leads to a cloudy and liquid product. It has surprisingly been discovered that by using a new families of thickening and / or gelling polymers and by associating them with cationic polymers, cosmetic formulations can be obtained which have a satisfactory viscosity at a relatively low pH, not doughy, non-greasy, which They extend well on the skin and the hair and give the latter good properties of softness, touch and carmenadura or desenredoredo while they have good properties of fixation. Thus, the subject of the present invention is cosmetic compositions for the treatment of keratin materials containing, in a cosmetically acceptable aqueous support, at least one anionic polymer. and an acrylic terpolymer which will be defined more in detail in the continuation of the description. This polymer makes it possible in particular to prepare aqueous or hydro-organic compositions containing cosmetically acceptable, clarified or unclarified solvents ranging from gelled products to solid sticks or pastes. The advantages of this polymer are to be stable in an electrolytic medium and to have a very good thickening power at pH equal to or greater than 5.5, which makes it possible to reach a good level of viscosity and be able to use high concentrations of alcohol. The acrylic terpolymer used according to the invention is soluble or dilatable in alkalis. It is characterized in that it comprises a) about 20 to 70% by weight, preferably 25 to 55% by weight, of a carboxylic acid having α, β-monoethylenic unsaturation; b) about 20 to 80% by weight, preferably 30 to 65% by weight, of a monomer having monoethylenic, non-surfactant unsaturation, different from a) c) about 0.5 to 60% by weight, preferably 10 to 50% by weight, of a non-ionic urethane monomer which is the reaction product of a non-ionic surfactant. monohydric ion with a monoisocyanate having monoethylenic unsaturation. The carboxylic acid with α, β-monoethylenic unsaturation: a) can be chosen from numerous acids and in particular from acrylic acid, methacrylic acid, itaconic acid and maleic acid. Methacrylic acid is preferred. A large proportion of acid is essential to give a polymeric structure which is solubilized and gives a thickener by reaction with an alkaline compound, such as sodium hydroxide, alkanolamines, amino methyl propanol or amino methyl propanediol. The terpolymer must also contain an important proportion indicated hereinabove of a monomer b) having monoethylenic unsaturation which has no surfactant property. Preferred monomers are those which give water-insoluble polymers when they are homopolymerized and are illustrated by alkyl acrylates and methacrylates of 1 to 4 carbon atoms, such as methyl acrylate, ethyl acrylate, butyl acrylate or the corresponding methacrylates. The most particularly preferred monomers are methyl and ethyl acrylates. Other monomers that can be used are styrene, vinyltoluene, vinyl acetate, acrylonitrile and vinylidene chloride. Non-reactive monomers are preferred, these monomers are those in which the Unique ethylene group is the only reactive group under the conditions of polymerization. However, monomers containing reactive groups under the action of heat can be used in certain situations, such as hydroxyethyl acrylate. The monohydric nonionic surfactants used to obtain the nonionic urethane monomer c) are well known and are in general alkoxylated hydrophobic compounds containing an alkylene oxide which forms the hydrophilic part of the molecule. The hydrophobes are generally constituted by an aliphatic alcohol or an alkylphenol in which a carbon chain containing at least six carbon atoms constitutes the hydrophobic part of the surfactant. Preferred monohydric nonionic surfactants have the formula: wherein R is an alkyl group of 6 to 30 carbon atoms or aralkyl of 8 to 30 carbon atoms, R 'is an alkyl group of 1 to 4 carbon atoms, n is an average number of about 5 to 150 and m it is an average number of approximately 0 to 50, with the proviso that n is at least as large as -m and that n + m = 5 - 150.

Monoisocyanate with monoethylenic unsaturation used to form the nonionic urethane monomer c) can be chosen from a variety of compounds. A compound containing any copolymerizable unsaturation such as an acrylic or methacrylic unsaturation can be used. An allylic unsaturation conferred by allyl alcohol can also be used. The preferred monoethylenic monoisocyanate is 1'-a, a-dimethyl-m-isopropenyl-benzylisocyanate.
