ABSTRACT:
The present invention relates to hairspray compositions comprising from about 50% to about 99.9% by weight of an alcohol solvent, and from about 0.1% to about 30% by weight of a silicone-containing adhesive block copolymer having a weight average molecular weight from about 10,000 grams/mole to about 10,000,000 grams/mole and which is formed from the free radical polymerization of an ethylenically unsaturated monomer with select silicone macroinitiators, preferably silicone macroazoinitiators. The hairspray compositions, when dried, preferably have a cohesive strength of greater than about 0.5 kgf/mm.sup.2, a total energy absorption per unit volume of greater than about 0.55 kgfmm/mm.sup.3, an impact strength of greater than about 7000 ergs, and an improved removeability from hair as defined by a hair stiffness value of from 0 to about 3.5 (0 to 4 scale) and a hair flaking value of from 0 to about 3.5 (0 to 4 scale). These hairspray compositions provide improved hair styling performance, and in particular provide improved maintenance or hold when applied to dry hair and causes minimal or no drooping of the hair during or immediately after application.
