Abstract:
A process for making a hair cleanser composition which comprises admixing conventional constituents of hair cleansers with a neutralized or partially neutralized copolymer obtainable fromA) from 50 to 99% by weight of monoethylenically unsaturated carboxylic acid, B) from 1 to 50% by weight of at least one comonomer selected from groups a) to d), or a mixture of different comonomers selected from groups a) to d): a) monoethylenically unsaturated carboxylic acid esters with a saturated C8-C30-alcohol, b) N-alkyl- or N,N-dialkyl-substituted carboxamides, the alkyl radicals independently of one another being aliphatic or cycloaliphatic alkyl radicals having at least 8 to 18 carbon atoms, c) vinyl esters of aliphatic C8-C30-carboxylic acids, d) C8-C18-alkyl vinyl ethers, and C) from more than 0 to at most 49% by weight of at least one comonomer selected from groups e) to h), or a mixture of different comonomers selected from groups e) to h): e) C1-C4-alkyl ester of a monoethylenically unsaturated carboxylic acid C, f) Nâ€”C1-C4-alkyl- or N,Nâ€”C1-C4-dialkyl-substituted carboxamide of a monoethylenically unsaturated carboxylic acid C, it being possible for the alkyl radicals of the dialkylamide to be identical or different, g) nitrile of a monoethylenically unsaturated carboxylic acid C, h) acrylamidoglycolic acid, vinylsulfonic acid, allylsulfonic acid, methallylsulfonic acid, styrenesulfonic acid, 3-sulfopropyl acrylate, 3-sulfopropyl methacrylate, acrylamidomethylpropanesulfonic acid, vinylphosphonic acid, allylphosphonic acid, acrylamidomethanepropanephosphonic acid, N-vinylpyrrolidone, N-vinylcaprolactam, N-vinylimidazole, N-vinyl-2-methylimidazole, N-vinyl-4-methylimidazole, diallylammonium chloride, vinyl acetate and vinyl propionate, where the alkyl groups can be substituted with hydroxyl groups, and the monoethylenically unsaturated carboxylic acid C can be selected independently of one another for groups e), f), g) from: acrylic acid, methacrylic acid, dimethacrylic acid, ethacrylic acid, maleic acid, citraconic acid, methylenemalonic acid, allylacetic acid, vinylacetic acid, crotonic acid, fumaric acid, mesaconic acid and itaconic acid.
