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.

Abstract: Non-aerosol pump hair spray compositions herein are applied as a fine spray mist, without nozzle clogging, and dried rapidly, to provide superior hair holding power. The compositions includes a hair fixative resin which is a terpolymer of a vinyl ester, an alkyl maleate half ester, and an acrylate ester of a saturated, hydroxylated bicyclic hydrocarbon, in an amount between 6 and 20% solids, and at a relative viscosity of from 1.10 to below 1.30.

Abstract: Non-aerosol pump hair spray compositions herein are applied as a fine spray mist, without nozzle clogging, and dried rapidly, to provide superior hair holding power. The compositions includes a hair fixative resin which is a copolymer of maleic anhydride and an alkyl vinyl ether, and the ethyl and butyl half-esters thereof, in an amount of between 6 and 20% solids. In suitable embodiments of the invention, the resin is the C.sub.2 -C.sub.4 alkyl half-ester of maleic anhydride and C.sub.1 -C.sub.5 alkyl vinyl ether having a relative viscosity of about 1.20 to 1.35 (1% in ethanol).
