摘要:
The present invention provides cosmetic compositions containing a copolymer obtainable by the copolymerization of at least one methacrylic acid ester, methacrylic acid, acrylic acid, optionally at least one compound containing amino groups and polymerizable by free radical polymerization, and optionally other olefinically unsaturated compounds polymerizable by free radical polymerization. The copolymerization can be carried out in the presence of silicones f) containing polyalkylene oxide.
