Abstract
The present invention relates to cosmetic compositions which comprise a hyperbranched copolymer of the monomers dodecenyl succinic acid anhydride, diisopropanol amine and bis-dimethylaminopropyl amine having quaternary terminal groups and a liquid and/or solid organic UV-filter. The copolymer is used in a cosmetic composition comprising the UV-filter for reducing the material transfer to a contacted surface. Preferably the copolymer is polyquatemium-110.
Claims19
A cosmetic composition comprising:
- (a) a hyperbranched copolymer of the monomers:
- (i) dodecenyl succinic acid anhydride,
- (ii) diisopropanol amine, and
- (iii) bis-dimethylaminopropyl amine, wherein
- the hyperbranched copolymer has a molecular weight Mn of between 1200 and 4000 g/mol and includes terminal groups of the formula:
- and
- (b) at least one liquid organic UV filter and/or at least one solid organic UV filter, wherein
- the cosmetic composition is a sun care composition.
A method for reducing material transfer to a contacted surface of a cosmetic composition comprising at least one liquid organic UV filter and/or at least one solid organic UV filter, wherein the method comprises incorporating into the cosmetic composition an amount of a hyperbranched copolymer sufficient to reduce the material transfer of the cosmetic composition to the contacted surface, wherein
- the hyperbranched copolymer has a molecular weight Mn of between 1200 and 4000 g/mol and is a copolymer of the monomers:
- (i) dodecenyl succinic acid anhydride,
- (ii) diisopropanol amine, and
- (iii) bis-dimethylaminopropyl amine, and wherein
- the hyperbranched copolymer includes terminal groups of formula:
