Science
Mechanism of Action
As part of the acryloyloxyethyl phosphorylcholine polymer family, this ingredient works to condition the skin, contributing to its overall health and appearance. It can form a delicate, non-occlusive film on the skin's surface, attract and retain moisture from the atmosphere, and significantly enhance the texture and stability of products by increasing their viscosity.

Stability
Research on a related hydrogel, 2-methacryloyloxyethyl phosphate (PMOEP), indicates minimal response to acidic pH conditions. Increased swelling properties were observed around neutral pH 7, remaining consistent at higher basic pH levels, suggesting robust stability across a wide pH range, with potential optimal performance in neutral to basic environments.
Safety
Safety Profile
The Expert Panel for Cosmetic Ingredient Safety (CIR) concluded this ingredient, as part of a group of 8 acryloyloxyethyl phosphorylcholine polymers, is safe for use in cosmetics under current practices and concentrations. While no specific maximum concentration is set for this ingredient, related polyacrylamides are subject to EU Cosmetics Directive restrictions on residual acrylamide content: 0.1 mg/kg for leave-on body care products and 0.5 mg/kg for other cosmetic products.
