USE OF WATER-SOLUBLE COPOLYMERS AS ACTIVE INGREDIENTS IN COSMETICS

摘要

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 R<1> et R<2> 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 R<3> 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 R<4> represents H, alkyl or aralkyl. The invention also pertains to cosmetics containing said polymers.
