Abstract
The invention relates to the use of graft copolymers obtained by radical graft copolymerisation of a) at least one open-chained N-vinylamide compound of general formula (I) wherein R1, R2, R3 represents H or C1-C6-alkyl and b) optionally, one or several other copolymerizeable monomers on a polymergraft base c) for cosmetic applications, with the proviso that if the polymer graft base is compound containing polyether, the copolymerizeable polymer b) does not represent vinylester. 1
Claims18
The use of graft copolymers obtainable by free-radical graft copolymerization of
- a) at least one open-chain N-vinylamide compound of the formula (I)
- 15
- where R1, R2, R3=H or C1-C6-alkyl, and
- b) optionally one or more further copolymerizable monomers
- to a polymeric graft base c), for cosmetic applications, with the proviso that if the polymeric graft base is a polyether-containing compound, the copolymerizable polymer b) is not a vinyl ester.
