Abstract:
An anhydrous aerosol hairspray composition comprising:(a) from about 0.1% to about 10% by weight of a silicone-grafted polycarboxylic acid copolymer having a weight average molecular weight of from about 10,000 to about 300,000, wherein the silicone-grafted polycarboxylic acid copolymer has a vinyl polymeric backbone, and a polysiloxane macromer grafted to the backbone wherein the polysiloxane macromer has a weight average molecular weight of from about 500 to about 50,000;(b) a neutralizing system comprising a combination of an organic and inorganic base, wherein the organic base is at a level sufficient to neutralize from about 25% to about 80% of the acid groups on the silicone-grafted copolymer while the inorganic base is at a level sufficient to neutralize from about 0.5% to about 20% of the acid groups on the silicone-grafted copolymer;(c) from about 5% to about 50% by weight of a nonhydrocarbon propellant that is substantially free of hydrocarbon propellants; and(d) the balance comprising a carrier suitable for application to hair;wherein said composition contains less than about 5%, by weight, of water; andwherein said composition contains less than about 5%, by weight, of hydrocarbon propellants.
