Patent ID: 8865193

Claim:
A method for fixing a keratin-type structure, comprising the step of applying to the keratin-type structure a polymer emulsion comprising: a first copolymer; a second copolymer; and a resin distinct from the second copolymer, the resin having an average molecular weight from about 500 to about 15,000 daltons, 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 (C 1 -C 6 ) 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 (C 1 -C 6 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.
