Science
Mechanism of Action
This copolymer operates by creating a fine, non-occlusive film upon the skin's surface, which contributes to a smoother tactile experience and extended product longevity. Furthermore, it efficiently increases the viscosity of formulations, optimizing texture, and provides water-resistant properties. It can also serve as an opacifying agent, reducing product translucency.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined Ethylene/Calcium Acrylate Copolymer, alongside related acrylates copolymers, to be safe for cosmetic use when formulated to prevent irritation. While generally tolerated, some reports indicate potential for skin irritation, with a heightened risk of allergic reactions at higher concentrations. The maximum reported usage for leave-on dermal products is 25%, though it can be used up to 98.6% in nail formulations. Its use is sanctioned by the FDA as an indirect food additive in packaging and is approved for cosmetic applications under European Union regulations.
