Title: Hair-care composition containing a thermoplastic polymer

Abstract: The hair-care composition broadly comprises an ethanolic cosmetic vehicle and between about 1 and 20% by weight, based on the total weight of the composition, of film-forming thermoplastic resinous polymeric material which in dried condition is resistant to softening by humidity, insoluble in water alone but dispersible in water having a cosmetic pH, fully soluble in ethanol, and consists essentially of the addition free-radical polymerization product formed by polymerizing a monomeric mixture consisting essentially of, by weight percent: 1 to 20% of 1,1 dimethyl-1,(2-hydroxypropyl) amine methacrylimide; 8 to 45% of N-vinyl pyrrolidone; and 35 to 89% of vinyl acetate.
