  • Hydrocarbon tolerant hair fixing compositions
    Patent number: 4923695
    Abstract: This invention prevents 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 .alpha.-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.
