Abstract
Abstract Terpolymer of crotonic acid, vinyl acetate and an allyl or methallyl ester having the formula R1O ¦ PARALLEL R2-C-C-O-CH2-C=CH2 ¦¦ CH3R' wherein R' hydrogen or CH3, R1 is a saturated hydrocarbon chain containing 1-6 carbon atoms and R2 is -CH3 or -CH(CH3)2, with the proviso that the sum of the number of carbon atoms in R1 + R2 is equal to or less than 7. The terpolymer is employed with a cosmetic carrier or vehicle to provide a cosmetic composition for the hair, such as a hair lacquer or hair setting lotion, generally in amounts of about 1-4 weight percent of the composition.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A hair lacquer composition or hair setting composition comprising a hydroalcoholic carrier or an alcoholic carrier and a terpolymer of 6-15 weight percent crotonic acid, 65-86 weight percent vinyl acetate and 8-20 weight percent of an allyl or methallyl ester of the formula ##EQU3## wherein R' is selected from the group consisting of hydrogen and --CH 3 , R 1 is a saturated hydrocarbon chain, linear or branched, having 1-6 carbon atoms, and R 2 is selected from the group consisting of --CH 3 and --CH(CH 3 ) 2 , with the proviso that the sum of the number of carbon atoms in R 1 and R 2 is equal to or less than 7, said terpolymer being present in an amount of about 1--4 weight percent of said composition.
Claim 2
Dependent Claim
130 words
A hair lacquer composition or hair setting composition comprising a hydroalcoholic carrier or an alcoholic carrier and a terpolymer of 6-15 weight percent crotonic acid, 65-86 weight percent vinyl acetate and 8-20 weight percent of an allyl or methallyl ester of the formula ##EQU3## wherein R' is selected from the group consisting of hydrogen and --CH 3 , R 1 is a saturated hydrocarbon chain, linear or branched, having 1-6 carbon atoms, and R 2 is selected from the group consisting of --CH 3 and --CH(CH 3 ) 2 , with the proviso that the sum of the number of carbon atoms in R 1 and R 2 is equal to or less than 7, said terpolymer being present in an amount of about 1--4 weight percent of said composition.
Claim 3
Dependent Claim
68 words
The composition of claim 1 wherein said terpolymer is present in an amount of about 1-4 weight percent, said carrier is alcoholic and comprises about 6-45 weight percent based on the total weight of the composition of a lower alkanol and about 54-90 weight percent based on the total weight of the composition of a liquified gaseous propellant, said composition being packaged, under pressure, in an aerosol container.
Claim 4
Dependent Claim
23 words
The composition of claim 1 wherein said terpolymer is present in an amount of about 1-3 weight percent and said carrier is hydroalcoholic.
