Abstract:
1. A procedure for preparing a cosmetic comprising preparing the cosmetic using an inverse emulsion having an aqueous phase and an organic phase comprising from about 20 to about 70% by weight of an acrylic polymer obtained by inverse emulsion polymerization of i. from about 55 to 76% by weight of an anionic acrylic monomer containing a strongly acidic functional group wherein the anionic acrylic monomer containing a strongly acidic functional group is 2-acrylamido-2-methylpropanesulfonic acid; ii from about 0.1 to 5% by weight of a cationic acrylic monomer of the formula (I): iii. from about 25 to 45% by weight of a C wherein the weight ratio between the aqueous phase and the organic phase is from about 4:1 to about 2:1.
