Polymers having improved cosmetic wear properties

摘要

The present invention relates generally to improvements of wear resistant cosmetic compositions. Specifically, this invention relates to a cosmetic composition containing particular copolymers with glass transition temperatures greater than 70° Celsius that demonstrate enhanced wear in combination with a smooth, non-tacky feel. Since most carrier solvents formulated into cosmetics are weak solvents with high boiling points and slow evaporation rates the applied films remain wet and tacky resulting in poor cosmetic performance. The polymers of the present invention overcomes this deficiency due to the high Tg associate with the polymer which yields an apparent faster dry time in the applied coating thus improving the cosmetic's film integrity.
