Abstract

Abstract Copolymer of (a) an unsaturated acid having the formula R-CH = CH-(CH2-O-CH2)n-COOH wherein n = 0 or 1, and when n = O, R = CH3 and when n = 1, R = H, (b) a vinyl ester of the formula O PARALLEL R-C-O-CH=CH2 wherein R is CH3 or C2H5, (c) at least one branched allyl or methallyl ester of the formula R1O ¦ PARALLEL R2-C-C-O-CH2-C=CH2 ¦¦ CH3R' wherein R' represents hydrogen or CH3, R1 represents a saturated hydrocarbon chain, linear or branched, having 1-6 carbon atoms and R2 represents CH3 or CH(CH3)2, with the proviso that the sum of the number of the carbon atoms in R1+R2 is equal to or less than 7 and (d) a monomer selected from the group consisting of a vinyl ether of the formula CH2 = CH-O-R3 wherein R3 is linear or branched alkyl having 1-12 carbon atoms, a vinyl ester having a fatty chain and having the formula O PARALLEL R4-C- O-CH= CH2 wherein R4 is linear alkyl having 7-11 carbon atoms and a linear allyl or methallyl ester of the formula O PARALLEL R5-C-O-CH2-C=CH2 ¦ R' wherein R' is hydrogen or CH3 and R5 is linear alkyl having 1-11 carbon atoms. The copolymer 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 an amount of about 1-4 weight percent of the composition.

Claim 2
Dependent Claim 273 words
A hair lacquer composition or a hair setting composition comprising a hydroalcoholic carrier or an alcoholic carrier and a copolymer of 2-15 weight percent of an unsaturated acid having the formula R -- CH = CH -- (CH 2 -- O -- CH 2 ) n -- COOH wherein n = 0 or 1 and when n = 0, R = CH 3 and when n = 1, R = H; 55-89.5 weight percent of a vinyl ester having the formula ##EQU9## wherein R is CH 3 or C 2 H 5 ; 8-20 weight percent of at least one branched allyl or methallyl ester having the formula ##EQU10## wherein R' represents hydrogen or CH 3 , R 1 represents a saturated hydrocarbon chain, linear or branched, having 1-6 carbon atoms and R 2 represents CH 3 or CH(CH 3 ) 2 , with the proviso that the sum of the number of the carbon atoms in R 1 +R 2 is equal to or less than 7; and 0.5-10 weight percent of a monomer selected from the group consisting of a vinyl ether having the formula CH 2 = CH -- O -- R 3 wherein R 3 is linear or branched alkyl having 1-12 carbon atoms, a vinyl ester having a fatty chain and having the formula ##EQU11## wherein R 4 is linear alkyl having 7-11 carbon atoms and a linear allyl or methallyl ester having the formula ##EQU12## wherein R' is hydrogen or CH 3 and R 5 is linear alkyl having 1-11 carbon atoms, said copolymer being present in an amount of about 1-4 weight percent of said composition.
Claim 3
Dependent Claim 68 words
