Abstract:
A composition for washing keratin materials, comprising, in a cosmetically acceptable medium:I) at least one anionic, amphoteric or nonionic detergent surfactant; II) at least 1.5% by weight, relative to the total weight of the composition, of at least one nacreous and/or opacifying agent chosen from: i) esters of long-chain (C10-C30) monoalcohols and of long-chain (C10-C30) fatty acids; ii) long-chain (C10-C30) fatty alkyl ethers; iii) long-chain (C10-C30) esters of long-chain (C10-C30) alkanolamides; iv) N,N-dihydrocarbyl(C10-C30)amidobenzoic acid and its salts; v) alcohols containing from 27 to 48 carbon atoms and comprising one or two ether and/or thioether or sulphoxide groups; and III) at least one acrylic terpolymer which contains, in amounts based on the total weight of monomers constituting the terpolymer: acrylate monomer (a), in amount of 5% to 80% by weight and selected from the group consisting of a C1-C6 alkyl acrylate and a C1-C6 alkyl methacrylate; monomer (b), in an amount of 5% to 80% by weight and selected from the group consisting of a heterocyclic vinyl compound containing at least one nitrogen or sulphur atom, a (meth) acrylamide, a mono- and di(C1-C4) alkylamino(C1-C4) alkyl (meth)acrylate, and a mono- and di(C1-C4) alkylamino(C1-C4) alkyl (meth) acrylamide; and monomer (c), in an amount of 0.1% to 30% by weight and selected from the group consisting of: i) a urethane produced by reaction between a monoethylenic unsaturated isocyanate and a nonionic surfactant encompassing a block copolymer of 1,2-butylene oxide and of ethylene oxide containing a C1-4 alkoxy end; ii) a copolymerizable ethylenic unsaturated surfactant monomer obtained by condensing a nonionic surfactant with an &agr;, &bgr;-ethylenic unsaturated carboxylic acid or its anhydride; iii) a urea surfactant monomer produced by reacting a monoethylenic unsaturated monoisocyanate with a nonionic surfactant containing an amine functionality; iv) a (meth) allyl ether of formula CH2&boxH;CR1CH2OAmBnApR2 in which R1 denotes a hydrogen atom or a methyl group, A denotes propylenoxy or butylenoxy group, B denotes ethylenoxy, n is equal to zero or denotes an integer less than or equal to 200, m and p denote zero or an integer less than n, and R2 is a hydrophobic group of at least 8 carbon atoms; and v) a nonionic urethane monomer produced by reacting a monohydric nonionic surfactant with a monoethylenic unsaturated isocyanate.
