Science
Mechanism of Action
Functioning primarily as a skin protectant, this copolymer forms a protective, non-occlusive film on the skin's surface. This film aids in maintaining skin hydration and can facilitate the transport of beneficial compounds. Its polyethylene glycol foundation ensures a non-toxic and non-immunogenic profile, contributing to its favorable skin tolerance.

Formulation
Stability
This ingredient exhibits good solubility in both water and most organic solvents. The water solubility and hygroscopicity of related polyethylene glycols generally decrease with increasing molar mass. It is capable of forming crosslinked polymer networks and PEG hydrogels upon polymerization.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has assessed acrylates copolymers, including this ingredient, as safe for use in cosmetics when formulated to specific concentration or use limitations, and when designed to prevent irritation. Due to its large molecular size, this polymethyl methacrylate-based ingredient is unlikely to penetrate the stratum corneum, thereby minimizing systemic toxicity concerns. However, a general likelihood of irritation exists, which may increase when combined with other problematic ingredients.
