Patent ID: 7025973

Claim:
An acidic cosmetic, dermatological or pharmaceutical liquid or gel composition which comprises an inorganic or groan ic acid and at least one copolymer obtained by free-radical copolymerization of A) acryloyldimethyltaurine or acryloyldimethyltaurates, and mixtures thereof, B) optionally, one or more further olefinically unsaturated, noncationic, comonomers which have at least one oxygen, nitrogen, sulfur or phosphorus atom and possess a molecular weight of less than 500 g/mol, C) optionally, one or more olefinically unsaturated, cationic comonomers which have at least one oxygen, nitrogen, sulfur or phosphorus atom and possess a molecular weight of less than 500 g/mol, D) one or more silicon-containing components capable of free-radical polymerization and having a functionality of at least one, E) optionally, one or more fluorine-containing components capable of free-radical polymerization and having a functionality of at least one, F) optionally, one or more olefinically mono- or polyunsaturated, macromonomers each possessing at least one oxygen, nitrogen, sulfur or phosphorus atom and having a number-average molecular weight of greater then or equal to 200 g/mol, the macromonomers not being a silicon-containing component D) or fluorine-containing component E), and where at least one macr6monomer is a macromonomer 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 Y is selected from the group consisting of —O—, —C(O)—, —C(O)—O—, —S—, —O—CH 2 —CH(O—)—CH 2 OH, —O—CH 2 —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 the components D) to G), and wherein said acid ranges from 0.05 to 20 weight percent of said composition.
