ACRYLIC ACID/ACRYLONITROGENS COPOLYMER.

Valuable CAS 61788-40-7 / BINDING, FILM FORMING, SKIN CONDITIONING, VISCOSITY CONTROLLING

ACRYLIC ACID/ACRYLONITROGENS COPOLYMER is a synthetic polymer valued for its film-forming properties, creating a smooth barrier on the skin. It significantly enhances formulation stability and contributes to a product's water resistance.

Summary

Binding Film Forming Skin Conditioning Viscosity Controlling Thickening Suspending Water Resistance

Science

Mechanism of Action

This copolymer operates by forming a breathable, micron-sized film on the skin's surface, which imparts a smooth tactile sensation and enhances the formulation's water-repellent characteristics. Beyond skin interaction, it serves as a critical rheology modifier, thickening formulations and acting as a suspending agent to uniformly disperse particles like pigments or inorganic sunscreens, ensuring even coverage and effortless application.

7%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that acrylates copolymers are safe for use in cosmetic applications when formulated to be non-irritating and used in concentrations up to 7%. Higher concentrations may increase the potential for irritation or allergic reactions. Manufacturers typically maintain residual monomer levels between 10 to 1000 ppm, with an upper limit of 1500 ppm, to ensure optimal safety and minimize potential adverse reactions.
