Patent ID: 7901697

Claim:
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): wherein R 1 is hydrogen or methyl; R 2 , R 3 , R 4 are, one independently of the others, hydrogen or a C1-C4 alkyl; Y is NH or O; A is a C 1 -C 6 alkylene; and X is chloride; and iii. from about 25 to 45% by weight of a C 3 -C 5 anionic acrylic monomer containing a carboxylic group; wherein the weight ratio between the aqueous phase and the organic phase is from about 4:1 to about 2:1.
