Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
A hair spray composition comprising: (a) about 65 to 80 percent by weight of a liquid concentrate phase and, (b) about 20 to 35 percent by weight of a propellant phase consisting of a hydrocarbon; the propellant phase selected from the group consisting of propane, n-butane, isobutane, or mixture thereof, said liquid concentrate phase based on the total weight of (a) and (b), from about 1 to 5 percent by weight of a water soluble film forming polymeric material selected from a group consisting of an acrylic resin, a methacrylic resin and mixtures thereof, from 2 to 30 percent by weight--water; from 0.4 to 2 percent by weight--of an organic base neutralizer for said polymeric material and sufficient ethanol or isopropanol, or mixtures thereof, to total 100 percent.
Claim 2
Dependent Claim
128 words
A hair spray composition comprising: (a) about 65 to 80 percent by weight of a liquid concentrate phase and, (b) about 20 to 35 percent by weight of a propellant phase consisting of a hydrocarbon; the propellant phase selected from the group consisting of propane, n-butane, isobutane, or mixture thereof, said liquid concentrate phase based on the total weight of (a) and (b), from about 1 to 5 percent by weight of a water soluble film forming polymeric material selected from a group consisting of an acrylic resin, a methacrylic resin and mixtures thereof, from 2 to 30 percent by weight--water; from 0.4 to 2 percent by weight--of an organic base neutralizer for said polymeric material and sufficient ethanol or isopropanol, or mixtures thereof, to total 100 percent.
Claim 3
Dependent Claim
40 words

Claim 5
Dependent Claim
12 words
A composition according to claim 3 wherein said organic base is 2-methyl-2-amino-1-propanol.
Claim 6
Dependent Claim
14 words
A composition according to claim 1 wherein said liquid concentrate phase contains 25% water.
