Patent ID: 7022791

Claim:
An electrolyte-containing cosmetic, dermatological or pharmaceutical composition comprising an electrolyte and which comprises at least one copolymer obtained by free-radical copolymerization of A) acryloyldimethyltaurine and/or acryloyldimethyltaurates, B) optionally, one or more further olefinically unsaturated, noncationic, comonomer which has at least one oxygen, nitrogen, sulfur or phosphorus atom and has a molecular weight of less than 500 g/mol, C) optionally, one or more olefinically unsaturated, cationic comonomer which has at least one oxygen, nitrogen, sulfur or phosphorus atom and has a molecular weight of less than 500 g/mol, D) optionally, one or more silicon-containing component capable of free-radical polymerization and having a functionality of at least one, E) optionally, one or more fluorine-containing component capable of free-radical polymerization and having a functionality of at least one, F) optionally, one or more olefinically mono- or polyunsaturated, macromonomer 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, the macromonomer not being a silicon-containing component D) or fluorine-containing component E), and where the at least one macromonomer is of formula (IV) in which R 3 , R 4 , R 5 , and R 6 independently of one another are hydrogen or n-aliphatic, iso-aliphatic, olefinic, cycloaliphatic, arylaliphatic or aromatic (C 1 –C 30 ) hydrocarbon radicals, v and w independently of one another are from 0 to 500, the sum of v and w is on average ≦1, and V is a bridge selected from the group consisting of —O—, —C(O)—, —C(O)—O—, —S—, —O—CH 2 —CH(O—)—CH 2 OH, —O—CH(OH)—CH 2 O—, —O—SO 2 —O—, —O—SO 2 —O—, —O—SO—O—, —PH—, —P(CH 3 )—, —PO 3 —, —NH—, and —N(CH 3 )—, G) optionally, the copolymerization taking place in the presence of at least one polymeric additive having number-average molecular weights of from 200 g/mol to 10 9 g/mol, H) with the proviso that component A) is copolymerized with at least one component selected from one of component D) to G).
