Patent ID: 7943157

Claim:
A cosmetic, dermatological or pharmaceutical composition which comprises at least one copolymer obtainable by free radical copolymerization of: a. acryloyldimethylaurine or an acryloyl dimethyltaurate or a mixture thereof; b. optionally, one or more olefinically unsaturated, noncationic, optionally cross linking comonomer which have at least one oxygen, nitrogen, sulfur or phosphorous atom and possess a molecular weight of less than 500 g/mol; c. one or more olefinically mono- or polyunsaturated, optionally cross linking macro monomer 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 macro monomers not being a silicon-containing component or fluorine-containing component; and d. the copolymerization taking place optionally in the presence of at least one polymeric additive having number-average molecular weights of from 200 g/mol to 109 g/mol.
