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, noncationic, optionally crosslinking comonomers containing at least one oxygen, nitrogen, sulfur or phosphorus atom and possessing a molecular weight of less than 500 g/mol,C) one or more mono- or polyolefinically unsaturated, optically crosslinking macromonomers each possessing at least one oxygen, nitrogen, sulfur or phosphorus atom and having a number-average molecular weight of greater than or equal to 200 g/mol, andD) taking place in the presence of at least one polymeric additive having number-average molecular weight of from 200 g/mol to 109g/mol.The water-soluble or water-swellable copolymers of the present invention are useful in formulating cosmetics.
