Science
Mechanism of Action
Functioning as a film-forming agent and humectant, this copolymer establishes a protective, breathable layer that helps to lock in hydration and defend the skin barrier. Its phosphorylcholine segments are engineered to form highly hydrated structures, actively preventing protein and lipid adsorption, inhibiting cell and bacterial adhesion, and promoting lubricity for a supple skin feel and enhanced biocompatibility. The Hydroxyethylcellulose component further refines product texture as a gelling, thickening, and rheology-modifying agent, ensuring excellent slip during application.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed acryloyloxyethyl phosphorylcholine polymers, including this copolymer, as safe for use in cosmetics under current practices. While a specific maximum concentration for this exact ingredient is not provided, a related ingredient (Acrylic Acid/Phosphorylcholine Glycol Acrylate Crosspolymer) has been reported safe up to 0.18% in leave-on products. Due to its molecular weight, significant skin penetration is not anticipated. The Hydroxyethylcellulose component holds an EWG rating of #1, indicating a high safety profile.
