Patent ID: 7279154

Claim:
A method for thickening or emulsifying a cosmetic, pharmaceutical, or dermatological composition, said method comprising adding to said composition at least one copolymer obtained by only a single step process consisting of free-radical copolymerization of acryloyldimethyltaurine or acryloyldimethyltaurate or a mixture thereof, with at least one component selected from the group consisting of: a) one or more silicon-containing component capable of free-radical polymerization and having a functionality of at least one, c) one or more olefinically mono- or polyunsaturated, macromonomer according to formula (IV) wherein 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 are in turn stoichiometric coefficients relating to the ethylene oxide units (EO) and propylene oxide units (PO), wherein v and w amount independently of one another to from 0 to 500, it being necessary for the sum of v and w to be on average ≧1, and Y is a chemical bridge 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 )—, each macromonomer having a number-average molecular weight of greater than or equal to 200 g/mol, and mixtures thereof.
