Water-based olefin-graft polymer system for multifunctional cosmetic applications

A method for fixing a keratin-type structure, comprising the step of applying to the keratin-type structure a polymer emulsion that includes:

• a first copolymer;
• a second copolymer;
• at least one stabilizing emulsifier;
• a resin distinct from the second copolymer, the resin having an average molecular weight from about 500 to about 15,000 daltons;
• and
• a polymer selected from a group consisting of oxidized polyethylene polymers and oxidized polypropylene polymers, said oxidized polyethylene polymer or oxidized polypropylene polymer including a cationic moiety,
• wherein:
• the first copolymer is a copolymer of ethylene and acrylic acid;
• the second copolymer includes two or more monomer units selected from the group consisting of an acrylic acid, methacrylic acid, ethyl acrylate, butyl acrylate, 2-ethyl hexyl acrylate, butyl methacrylate, methyl methacrylate, styrene, a (C1-C6) aminoalkyl ester of methacrylic acid or acrylic acid or a quaternized adduct thereof, a polyethylene glycol (PEG) modified acrylate or methacrylate, and a polypropylene glycol (PPG) modified acrylate or methacrylate, said PEG modified or PPG modified acrylate or methacrylate having 1-10 moles of ethylene oxide or propylene oxide per 1 mole of acrylic or methacrylic acid;
• and
• the resin includes two or more monomer units selected from the group consisting of a (C1-C6 ester of methacrylic acid or acrylic acid methacrylic acid, a polyethylene glycol (PEG) or a polypropylene glycol (PPG) modified acrylate or methacrylate, said PEG modified or PPG modified acrylate or methacrylate having 1-10 moles of ethylene oxide or propylene oxide per 1 mole of acrylic or methacrylic acid.
