ETHYLENE/ACRYYLIC ACID/VA COPOLYMER.

Valuable CAS 26713-18-8 / FILM FORMING

This versatile copolymer creates a thin, elastic film on the skin, effectively reducing moisture loss and enhancing product adherence. It also contributes significantly to formulation stability and acts as a binding agent for various cosmetic ingredients.

Science

Mechanism of Action

ETHYLENE/ACRYYLIC ACID/VA COPOLYMER functions primarily as a film former, establishing a subtle yet effective barrier on the skin's surface. This protective layer actively minimizes transepidermal water loss (TEWL), thereby aiding in moisture retention and ensuring sustained product efficacy. Furthermore, it stabilizes emulsions by preventing the separation of oil and liquid phases, binds diverse cosmetic components, and can serve as an opacifying agent to reduce transparency.

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that ETHYLENE/ACRYYLIC ACID/VA COPOLYMER and related acrylates copolymers are safe for cosmetic use when formulated to be non-irritating. These large polymers demonstrate minimal toxicity, with residual monomer levels meticulously maintained at low concentrations (typically below 20 ppm, though occasionally up to 1000 ppm). For leave-on dermal applications, a maximum reported concentration of 25% has been observed. This ingredient adheres to the general provisions for cosmetics within the European Union.
