Claims
- 1. A hair fixing composition containing low residual levels of residual monomer, the composition comprising a solvent selected from a group consisting of 1,1,1-trichloromethane, methylene chloride, ethanol, isopropanol, and water, and from 0.25 to 7%, by weight, of an interpolymer of 30 to 60% of a comonomer selected from the group consisting of N-alkyl acrylamide and N-alkyl methacrylamide wherein the alkyl group hereof contains from 2 to 12 carbon atoms; 12 to 18% of an acidic copolymerizable comonomer selected from the group consisting of acrylic acid, methacrylic acid, crotonic acid, itaconic acid, maleic acid, fumaric acid, and the (C.sub.1 -C.sub.4) alkyl half esters of maleic and fumaric acids; and 20 to 55% of at least one copolymerizable comonomer selected from the group consisting of (C.sub.1 -C.sub.12) alkyl acrylates, (C.sub.1 -C.sub.12) alkyl methacrylates, (C.sub.2 -C.sub.4) hydroxyalkyl acrylates, hydroxystearyl acrylate, hydroxyalkyl methacrylates, hydroxystearyl methacrylate, (C.sub.1 -C.sub.4) alkyl (C.sub.2 -C.sub.4) amino alkyl acrylates, (C.sub.2 -C.sub.4)alkyl (c.sub.2 -C.sub.4) aminoalkyl methacrylates, vinyl acetate, vinyl propionate, diacetone acrylamide, styrene,and alpha-methyl styrene; said interpolymer being sufficiently neutralized with an alkaline reagent to effect its solubility in water, wherein said polymer is prepared in homogeneous form in the presence of an organic solvent using, the solvent containing at least 40% ethanol as the polymerization initiator, a water soluble initiator in sufficient water to dissolve the initiator, the amount of water comprising 5 to 25% by weight of the total solvent.
- 2. The hair fixing composition of claim 1, wherein from 50 to 100% of the available carboxyl groups of the interpolymer are neutralized with an alkaline reagent.
- 3. A hair fixing composition of claim 1 wherein the polymer is formed from the polymerization of 30 to 50% N-tert octyl acrylamide, 12 to 18% acrylic or methacrylic acid, 32 to 38% methyl methacrylate, 2 to 10% hydroxypropyl acrylate and 2 to 10% of a (C.sub.1 -C.sub.4)alkyl (C.sub.2 -C.sub.4)aminoalkyl acrylate or methacrylate.
