<p>Cosmetic agent comprises: (a) at least a copolymer (a1) containing at least an imidazole structural unit (I) and at least a further pyrrolidin-2-one structural unit (II); and (b) at least an acrylate polymer different from copolymer (a1), where the polymer is polyacrylic acid, copolymer of methacrylic acid with acrylamido propane sulfonic acid, copolymer of acrylic acid with methacrylic acid or acrylic acid ester, copolymer of acrylic acid with methacrylic acid, acrylic acid ester or methacrylic acid ester and/or copolymer of acrylic acid ester with methacrylic acid. Cosmetic agent comprises: (a) at least a copolymer (a1) containing at least an imidazole structural unit of formula (I) and at least a further pyrrolidin-2-one structural unit of formula (II); and (b) at least an acrylate polymer different from copolymer (a1), where the polymer is polyacrylic acid, copolymer of methacrylic acid with acrylamido propane sulfonic acid, copolymer of acrylic acid with methacrylic acid or acrylic acid ester, copolymer of acrylic acid with methacrylic acid, acrylic acid ester or methacrylic acid ester and/or copolymer of acrylic acid ester with methacrylic acid. R : 1-30C-alkyl, 1-4C-aralkyl, 2-6C-alkenyl or 2-6C-hydroxyalkyl, preferably CH 3; X : an anion, preferably methosulfate; and n : 1-3, preferably 1. [Image].</p> |
