AGENT FOR KERATIN-CONTAINING FIBRES

摘要

The invention relates to agents for the treatment of keratin-containing fibres, in particular human hair, containing water and at least one copolymer, comprising at least one structural unit of formula (I), at least one structural unit of formula (II), at least one structural unit of formula (III) and at least one structural unit of formula (IV), in which R represents a (C1 to C4) alkyl group, in particular a methyl group, R is a hydrogen atom or a methyl group, R is a hydrogen atom or one equivalent of a physiologically acceptable cation, the agent having a viscosity of 50000 mPas to 500000 mPas (at 20 °C, Brookfield, Spindel TE, Helipath, 5 rpm, measurement point at 60 seconds), said agents having a stable viscosity, particularly against sweat, and being suitable in particular for temporary hair styling and for hair care, especially in the form of a hair creme or a hair gel.
