Description

COSMETIC COMPOSITION CONTAINING ON IORGANOSILOXAN AND PO POINT AN ACRYLIC TERPOLIMITY AND USE OF THIS COMPOSITION FOR TREATMENT OF KERATINIC MATTERS Description of the invention The present invention relates to cosmetic compositions containing in association at least one polydiorganosiloxane and an acrylic terpolymer, as well as the use of these compositions for the treatment of keratin materials, in particular hair . The applicants are cosmetic products particularly sought after for their conditioning properties, softening and detangling properties, in particular in hair formulation. It is often necessary, when using certain silicones such as those insoluble in aqueous medium, to introduce them in a thick or gelled support to keep them in suspension and obtain a stable composition. It is equally important to have non-greasy, non-greasy compositions that spread well on the skin and hair. In order to obtain a thick or gelled support, thickening and / or gelling polymers are used. Thickener and / or gelling polymers are known which comprise in their chain a hydrophilic part and a hydrophobic part constituted by a REF .: 30466 fatty chain as the product "PEMULEN TR1" marketed by the GOODRICH society or the "ACRYSOL" polymers marketed by the company ROHM & HAAS. The polymer "PEMULEN TR1" gives the formulations a pasty texture that does not spread well. The polymer "ACRYSOL" does not have a good gelling power and gives tangled and able formulations. It has surprisingly been discovered that by using a new families of thickening and / or gelling polymers and by associating them with the polydiorganosiloxanes, cosmetic formulations can be obtained which have a satisfactory viscosity at a relatively low pH, which are stable, non-greasy, pasty that spread well on the skin and hair. Thus, the present invention relates to cosmetic compositions containing, in a cosmetically acceptable aqueous support, at least one polyorganosiloxane and an acrylic terpolymer which will be defined in detail later in the description. This polymer makes it possible, in particular, to prepare aqueous or hydro-organic compositions containing cosmetically acceptable, rinsed or unclarified, thick or gelled solvents. 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. This polymer, used in association with at least one polyorganosiloxane, makes it possible to produce non-pasty gelled products which have a good ease of extension, are soft in application and stable in preservation. It also allows to improve the conditioning effect of the silicones on the hair, in particular its touch, its softness and its ability to disentangle. 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 turation; b) about 20 to 80% by weight, preferably 30 to 65% by weight, of a monomer having monoethylenic, non-surfactant turation, different from a) and 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 monohydric nonionic surfactant with a monoisocyanate having monoethylenic turation. The carboxylic acid with α, β-monoethylenic turation: a) can be chosen from numerous acids and in particular acrylic acid, methacrylic acid, itaconic acid and maleic acid. Methacrylic acid is preferred. A large proportion of acid is essential to give a polymer structure that is solubilized and gives a thickener by reaction with an alkaline compound, such as sodium hydroxide, canolamines, 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. Unreacted monomers are preferred, these monomers are those in which the single ethylenic 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: R 'I RO-fCH2-CH-r (CH2-CH2O) nH in which 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 is an average number of about 0 to 50, with the proviso that n is at least as large as my that n + m = 5 - 150.

As aralkyl groups, mention may be made in particular of alkyl groups (from 8 to 13 carbon atoms) phenyl. The preferred R 'group is the methyl group. 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. The acrylic terpolymer defined hereinbefore is obtained by means of aqueous emulsion copolymerization of components a), b) and c) which is quite usual and is described in the patent application EP-A-0 173 109. As terpolymers that can be to be used according to the invention, mention may be made of the reaction products of methacrylic acid component a), ethyl acrylate as component b) and a non-ionic urethane macromonomer such as compound c) having the following structure: which p 'is from 6 to 150 and preferably is equal to 130 and R2 is an alkyl radical of 8 to 13 carbon atoms, as described in example 3 of the patent application EP-A-0 173 109.

The acrylic terpolymer is present in the cosmetic compositions of the invention in concentrations from 0.01 to 20% by weight in relation to the total weight of the composition and preferably from 0.1 to 10% by weight.
