Science
Mechanism of Action
Upon application, DMAPA Acrylates/Acrylic Acid/Acrylonitrogens Copolymer rapidly constructs a flexible, non-occlusive polymeric film. This protective layer acts as a barrier, effectively smoothing the skin's texture and contributing to a soft, supple sensation. Its inherent film-forming capacity is crucial for enhancing the water repellency of cosmetic products.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that Acrylates Copolymers, a group inclusive of this ingredient, are safe for use in cosmetics when formulated to be non-irritating. For leave-on dermal products, the maximum reported safe concentration is 25%. Related vinylpyrrolidone polymers with high molecular weights and low residual monomer levels are generally considered safe, mitigating concerns regarding dermal absorption. While instances of skin irritation or contact dermatitis are uncommon, formulators are advised to conduct patch-testing for individuals with sensitive skin.
