A cosmetic dermatological or pharmaceutical composition contains a copolymer prepared by radical copolymerization of acryloyldimethyltaurine acid and/or acryloyldimethyltaurates. A cosmetic dermatological or pharmaceutical composition (A) contains a copolymer prepared by radical copolymerization of: (1) acryloyldimethyltaurine acid and/or acryloyldimethyltaurates； (2) optionally an olefinically unsaturated, non-cationic, optionally cross-linked comonomer that contains at least one oxygen, nitrogen, sulfur or phosphorous atom and has a mol. wt. of less than 500 g/mol； (3) optionally an olefinically unsaturated cationic comonomer that contains at least one oxygen, nitrogen, sulfur or phosphorous atom and has a mol. wt. of less than 500 g/mol； (4) optionally an at least monofunctional silicon containing component that is suitable for radical polymerization； (5) optionally an at least monofunctional fluorine containing component that is suitable for radical polymerization； (6) optionally a mono- or multi-olefinically unsaturated, optionally cross-linkable macromonomer containing at least one oxygen, nitrogen, sulfur or phosphorous atom and a number average mol. wt. of at least 200 g/mol whereby the macromonomer (6) is not (4) or (5). The copolymerization is carried out in the presence of a polymeric additive (7) having a number average mol. wt. of 200 g/mol-10 9>； g/mol with the proviso that (A) is copolymerized with at least one of (4)-(7).
