ABSTRACT:
The invention provides water-soluble or water-swellable copolymers obtained by free-radical copolymerization ofA) acryloyldimethyltaurine and/or acryloyldimethyltaurates,B) optionally, one or more other olefinically unsaturated, nopcationic comonomers,C) optionally, one or more olefinically unsaturated, cationic comonomers,D) optionally, (a) silicon-containing component(s),E) optionally, (a) fluorine-containing component(s),F) optionally, one or more macromonomers,G) the copolymerization taking place in the presence or absence of at least one polymeric additive,H) with the proviso that component A) is copolymerized with at least components selected from at least two of the groups C) to F).The water-soluble or water-swellable copolymers of the present invention are useful in formulating cosmetics.
