Abstract
A polymer emulsion for use in a cosmetic composition includes an olefin copolymer; a copolymer of an acidic monomer to include acrylic acid, methacrylic acid or other unsaturated, carboxyl containing monomer; optionally, at least one stabilizing emulsifier; optionally, a resin selected from a group consisting of an acrylic resin and styrene-acrylic resin, said resin having an average molecular weight from about 500 to about 15,000 daltons; and, optionally, a polymer selected from a group consisting of oxidized polyethylene polymers and oxidized polypropylene polymers, said polymer modified with cationic end-groups such as tallow alkyl amines.
