The present invention relates to the use of water-soluble copolymers consisting of such characteristic structural elements as a) acrylic acid amide of the general formula (I), where R1 et R2 stand, independently of each other, for H, alkyl, cycloalkyl, aryl or aralkyl, and b) units of the general formula (II), where A represents a chemical bond or an alkyl group, the R3 residues stand, independently of each other, for H, alkyl, cycloalkyl, aryl or arakyl or, together with the nitrogen atom to which they are linked, an aromatic or non aromatic five to seven member heterocyclic ring, possibly mono- or polysubstituted, possibly containing one or two more heteroatoms chosen from among O, N or S, and capable of being annelated with another aromatic or non aromatic five to seven member ring, and R4 represents H, alkyl or aralkyl. The invention also pertains to cosmetics containing said polymers.

La présente invention concerne l'utilisation d'un copolymère soluble dans l'eau, comprenant, en tant qu'éléments structurels caractéristiques, a) des unités de carboxamide acrylique de la formule générale (I), où R?1¿ et R?2¿ représentent, indépendamment l'un de l'autre, H, alkyle, cycloakyle, aryle ou aralkyle, et b) des unités de la formule générale (II), où A représente une liaison chimique ou un groupe alkyle, les résidus de R?3¿ représentent, indépendamment les uns des autres, H, alkyle, cylcoalkyle, aryle ou aralkyle ou, ensemble avec l'atome d'azote auquel ils sont liés, un noyau hétérocyclique, aromatique ou non aromatique, éventuellement mono- ou polysubstitué, de cinq à sept éléments, contenant éventuellement un ou deux autres hétéroatomes choisis parmi O, N et S, le noyau hétérocyclique pouvant être annélisé avec un autre noyau aromatique ou non aromatique de cinq à six éléments, et R?4¿ représente H, alkyle ou aralkyle. L'invention porte aussi sur les produits cosmétiques contenant ces copolymères.
