VP/VA Copolymer

* A film former * Also known as Polyvinylpyrrolidone/Vinyl Acetate Copolymer

VP/VA Copolymer is a film former used primarily in hair care products, but also found in mascaras, nail polishes, and some skin care products, because of its ability to inhibit the hair (or lashes) from absorbing moisture; it dries and forms a thin barrier on hair, nails or skin. When used in hair care products, it allows hair to hold a style longer by preventing moisture from entering the hair shaft. VP/VA Copolymer 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 (CosmeticsInfo.org).

Functions:

VP/VA Copolymer is a film former used primarily in hair care products, but also found in mascaras, nail polishes, and some skin care products, because of its ability to inhibit the hair (or lashes) from absorbing moisture; it dries and forms a thin barrier on hair, nails or skin.

VP/VA Copolymer 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 (CosmeticsInfo.org).

VP/VA Copolymer is also used as viscosity builders of water-based and oil-based types of products. It is CIR approved.

Safety Measures/Side Effects:

The Cosmetics Database rates VP/VA Copolymer as a low hazard ingredient, only noting potential organ system toxicity as a concern, based on studies that showed some system effects at higher doses than those found in cosmetics and personal care products. "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%" (CosmeticsInfo.org).
