VP/VA Copolymer is a Vinylpyrrolidone/vinyl acetate copolymer, a nonionic film-forming polymer for hair care applications. It is a white powder with a slight characteristic odor.
The solubility in water depends on the proportion of vinyl-pyrrolidone (increasing vinylpyrrolidone content makes it more hygroscopic); the solution is clear, almost colorless to slightly yellowish. VP/VA Copolymer is soluble in ethanol or isopropanol.
VP/VA Copolymer is used in hair care and styling products as a fixative and film-forming agent. It has exceptional properties both for aerosol sprays (hairsprays) and non-aerosol products like liquid setting lotions, gels, and mousses.
Thanks to the polymer's nonionic nature, VP/VA Copolymer provides stronger adhesion to the hair, but its washing-out and combing-out properties remain excellent. It is known under the trade name Luviskol® VA.Synonyms
