Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
58 words
A non-aerosol hair spray composition consisting essentially of from about 1 to 10 percent by weight of a copolymer of 70 to 90 percent weight percent methylmethacrylate and 10 to 30 weight percent methacrylic acid, the carboxyl groups of which are 50 to 100 percent neutralized with a water-soluble base, dissolved in 65 to 99 percent aqueous ethanol.
Claim 2
Dependent Claim
58 words
A non-aerosol hair spray composition consisting essentially of from about 1 to 10 percent by weight of a copolymer of 70 to 90 percent weight percent methylmethacrylate and 10 to 30 weight percent methacrylic acid, the carboxyl groups of which are 50 to 100 percent neutralized with a water-soluble base, dissolved in 65 to 99 percent aqueous ethanol.
Claim 3
Dependent Claim
29 words
A non-aerosol composition according to claim 1 additionally consisting essentially of 0.05 to 0.5 percent by weight, based on the copolymer, of a silicone or fatty acid ester plasticizer.
Claim 4
Dependent Claim
40 words
A non-aerosol composition according to claim 1 having 3 to 6 percent by weight of said copolymer, the carboxyl groups of which are 60 to 100 percent neutralized with a water-soluble base, dissolved in 93 to 96 percent aqueous ethanol.
Claim 5
Dependent Claim
39 words
A non-aerosol composition according to claim 1 containing a copolymer of 80 to 90 percent by weight methylmethacrylate and 10 to 20 percent by weight methacrylic acid, the carboxyl groups of which are neutralized with a water-soluble organic base.
Claim 6
Dependent Claim
15 words
A composition according to claim 1 wherein said base is a water soluble organic base.
Claim 7
Dependent Claim
14 words
A composition according to claim 1 wherein said organic base is an organic amine.
