Abstract
Abstract This invention presents two series of novel hair fixing compositions, the first comprising copolymers of acrylates, N-substituted acrylamides and acrylic acid; and the second comprising copolymers of vinyl acetate or propionate, vinyl esters of α-branched carboxylic acids, and alkyl maleates. Such materials, when neutralized with NaOH, KOH, or mixtures of these bases with certain long chain amines, exhibit an enhanced tolerance of non-halogenated hydrocarbons and are particularly useful.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
97 words
An improved hair fixing composition having increased hydrocarbon tolerance, for use in aerosol formulations, comprising a copolyomer of 20-35% (by wt.) of vinyl acetate or vinyl propionate, 35-50% (by wt.) of a vinyl ester of a C₅-C₁₈ α-branched carboxylic acid, and 25-40% (by wt.) of a C₃-C₈ monoalkyl maleate, wherein percentages total 100% and all the improvement comprises neutralizing at least 70% of the carboxylic acid functionalities with an alkaline neutralizing agent comprising at least one base selected from the group consisting of NaOH or KOH, such that the tolerance of the copolymer to hydrocarbons is enhanced.
Claim 2
Dependent Claim
97 words
An improved hair fixing composition having increased hydrocarbon tolerance, for use in aerosol formulations, comprising a copolyomer of 20-35% (by wt.) of vinyl acetate or vinyl propionate, 35-50% (by wt.) of a vinyl ester of a C₅-C₁₈ α-branched carboxylic acid, and 25-40% (by wt.) of a C₃-C₈ monoalkyl maleate, wherein percentages total 100% and all the improvement comprises neutralizing at least 70% of the carboxylic acid functionalities with an alkaline neutralizing agent comprising at least one base selected from the group consisting of NaOH or KOH, such that the tolerance of the copolymer to hydrocarbons is enhanced.
