Abstract
Abstract A hydroalcoholic, pressurized hair spray composition containing an anticorrosive agent for reducing corrosion in tinplate aerosol cans. Such compositions contain a hydrocarbon, water, a film-forming polymeric material, an organic base neutralizer, ethanol or isopropanol and as an anticorrosion agent, a phosphate salt of a quaternary ammonium compound.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
A hair spray composition comprising (a) about 60 to 90 percent by weight of a liquid concentrate phase, and (b) about 10 to 40 percent by weight of a propellant phase selected from the group consisting of propane, n-butane, isobutane, or mixtures thereof; said liquid concentrate phase, based on the total weight of (a) and (b), consists of from about 1 to 7% of a film-forming polymeric material; from 2 to 40 percent by weight water; from 0.05 to 0.6 weight percent of an organic base neutralizer; 0.1 to 3 percent by weight of a phosphate salt of a quaternary ammonium compound represented by the formula: ##STR3## wherein x is an integer from about 12 to 18 and m, n, and p are integers the sum of which total from about 3 to 12 as a corrosion inhibitor; and sufficient ethanol or isopropanol, or mixture thereof, to total 100 percent.
Claim 2
Dependent Claim
150 words
A hair spray composition comprising (a) about 60 to 90 percent by weight of a liquid concentrate phase, and (b) about 10 to 40 percent by weight of a propellant phase selected from the group consisting of propane, n-butane, isobutane, or mixtures thereof; said liquid concentrate phase, based on the total weight of (a) and (b), consists of from about 1 to 7% of a film-forming polymeric material; from 2 to 40 percent by weight water; from 0.05 to 0.6 weight percent of an organic base neutralizer; 0.1 to 3 percent by weight of a phosphate salt of a quaternary ammonium compound represented by the formula: ##STR3## wherein x is an integer from about 12 to 18 and m, n, and p are integers the sum of which total from about 3 to 12 as a corrosion inhibitor; and sufficient ethanol or isopropanol, or mixture thereof, to total 100 percent.
Claim 3
Dependent Claim
21 words
A composition according to claim 1 wherein x is an integer from 14-16 and m+n+p has an average of about 10.
Claim 4
Dependent Claim
49 words
A composition according to claim 1 wherein said film-forming copolymeric material is a vinyl acetate-crotonic acid copolymer, a polyvinylpyrrolidone copolymer, a vinylpyrrolidone-vinyl acetate copolymer, copolymers of methylvinyl ether and monoethyl ester of maleic acid, or monobutyl ester of maleic acid, or a copolymer of methyl methacrylate and methacrylic acid.
