Hair spray package with low volatile organic compound emission

Claim 1

An improved self-propelled aerosol hair spray package comprising, in combination, a pressurized aerosol container sealed with an aerosol valve containing an actuator button having an exit orifice in flow communication with said valve and an alcoholic hair spray composition sealed within the container, the improvement comprising the valve being a low delivery rate valve capable of discharging the hair spray composition through the exit orifice at a rate of 0.20 to 0.38 grams per second and the hair spray composition comprises from about 1% to about 10% by weight of the total composition of at least two compatible hair fixative polymers in a weight ratio of at least 99:1 to 1:99, wherein one polymer present differs in weight average molecular weight from at least one other by a factor of at least 1.5 and at least one polymer present has a weight average molecular weight of at least 100,000 wherein the polymers and their total weight present in combination with the aerosol valve and actuator button on the package results in a discharged atomized aerosol spray having a volume means particle size in the range of from about 60±12 microns, the remainder of the composition comprising both a solvent selected from the group consisting of C 2 -C 4 alcohols, water and mixtures thereof, there being no more than about 10% by weight water present based upon the total weight of the hair spray composition, and a propellant, wherein the package gives relatively the same number of uses, but has from about one-third to one-half of the volume of hair spray composition, as does a second package having (a) at least twice the discharge rate, (b) a volume mean average particle size in the same range, and (c) about one-half by weight of the hair fixative polymer content.
