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.
