Abstract
An improved hydrocarbon tolerant, aerosol hair spray resin composition includes a fixative polymer which is a tetrapolymer consisting essentially of (1) vinyl acetate, (2) vinyl neodecanoate or vinyl neononanoate, (3) monoisobutyl maleate and (4) N-t-butyl acrylamide, N-t-octyl acrylamide, or isobornyl (meth)acrylate, in a molar ratio from 10:10:15:1 to 26:1:15:1, preferably in a molar ratio of 12.5:7.5:15:1, exhibits advantageous small spray particle size, short tack and drying times, and hydrolytic stability, which are the desired performance characteristics on hair.
