Abstract:
% to about 6% by weight of a carboxylated polyurethane resin;(b) 0% to about 6% by weight of a second hair fixative resin;(c) 0% to about 80% by weight of an alcohol;(d) about 15% to about 95% by weight water;wherein the carboxylated polyurethane resin has a weight average molecular weight of about 10,000 to about 80,000, a polydispersibility index of about 1 to about 4, an acid value of about 7 mg to about 50 mg KOH/g of resin, a melting point of about 40.degree. C. to about 100.degree. C., and is a reaction product of a mixture consisting essentially of:(i) about 10% to about 90% by weight of the mixture of a polyoxyalkylene diol having a number average molecular weight of about 200 to about 10,000(ii) about 0.01 % to about 20% by weight of the mixture of an alkylene glycol;(iii) about 3% to about 80% by weight of the mixture of an organic diisocyanate;(iv) about 10% to about 8% by weight of the mixture of a 2,2-di(hydroxymethyl)alkanoic acid; and(v) about 0.1% to about 0.5% by weight of the mixture of water, wherein a ratio of isocyanate groups to hydroxyl groups is about 0.5 to about 9.0.
