Science
Mechanism of Action
As a film former and humectant, this copolymer operates by drawing moisture into the skin while simultaneously creating a thin, protective barrier on the surface. This dual action significantly reduces trans-epidermal water loss, contributing to enhanced skin hydration, softness, and elasticity. In haircare, it improves combability, imparts shine and softness, and functions as an antistatic agent.

Polyquaternium-10, a key component of this copolymer, generally maintains stability within a pH range of 3.0-7.0, exhibiting high cationic activity across this useful pH spectrum.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that this polymer, as part of a group of 8 acryloyloxyethyl phosphorylcholine polymers, is safe for use in cosmetics under current practices and concentrations. Initial evaluations noted significant data needs; however, the final assessment relied on read-across data from structurally similar polymers like Polyquaternium-51 and Polyquaternium-61. The maximum use concentration for this specific copolymer was not reported in the 2020 Council survey; a related ingredient, Acrylic Acid/Phosphorylcholine Glycol Acrylate Crosspolymer, had a reported maximum use concentration of 0.18%.
