Abstract
Improved hair fixative compositions are prepared from copolymers containing specific alpha-aminoethylenephosphonate betaine monomers. The resulting fixative compositions exhibit an enhanced tolerance of non-halogenated hydrocarbons, yet also exhibit a high degree of shampoo removability, making them particularly useful in aerosol formulations using non-halogenated hydrocarbon propellants.
