VP/VA Copolymer

Safety Information

Expert Panel for Cosmetic Ingredient Safety

The safety of vp/va copolymer has been assessed by Expert Panel for Cosmetic Ingredient Safety. The Expert Panel evaluated the scientific data and concluded that polyvinylpyrrolidone/vinyl acetate copolymer was safe as a cosmetic ingredient under present conditions of use and concentrations. In 2003, as part of the scheduled re-evaluation of ingredients, the Expert Panel considered available new data on vp/va copolymer and reaffirmed the above conclusion.

The Expert Panel reviewed acute oral toxicity studies which showed low to no toxicity. No effects were reported in chronic oral and inhalation studies of vp/va copolymer. VP/VA copolymer placed in the eye at concentrations ranging from 25% to 50% in alcohol produced no reaction to severe irritation at higher concentrations.

Acute skin irritation studies of 50% vp/va copolymer in alcohol on abraded and intact skin produced mild skin irritation. VP/VA copolymer was not a sensitizer after intracutaneous injections. Formulations containing 1.75%, 4.0% and 5.0% vp/va copolymer produced no irritation in 24-hour clinical patch tests nor any evidence of sensitization in a repeated insult patch test at a concentration of 5.0%.

VA/VP copolymer may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European Union.

VP/VA Copolymer

What Is It?

Polyvinylpyrrolidone/vinyl acetate (vp/va) copolymer is a white, free-flowing powder. In cosmetics and personal care products, vp/va copolymer is used primarily in the formulation of hair care products but can also be found in skin and nail products.

Why Is It Used?

VP/VA copolymer helps hair hold its style by inhibiting the hair’s ability to absorb moisture. VP/VA copolymer dries to form a thin coating on the skin, hair or nails. It is also used to hold together the ingredients of a compressed tablet or cake and helps to distribute or to suspend an insoluble solid in a liquid.

Scientific Facts

VP/VA copolymer is a polymer prepared by combining relatively small chemical compounds called monomers into a very large molecule that has very different properties. VP/VA copolymer is a large molecule made from vinyl pyrrolidone (VP) and vinyl acetate (VA) monomers. The copolymer only contains residual amounts of the original monomers.
