Science
Mechanism of Action
This acrylate polymer functions by forming a coherent, flexible film on the skin. This film acts as a physical barrier that improves the adherence and stability of cosmetic products, thereby increasing their durability and enhancing smooth application across the skin.

Stability
While the polymer itself is generally stable, its monomer precursor, 2-ethylhexyl acrylate, polymerizes readily and requires stabilization with inhibitors (e.g., MEHQ) and storage conditions below 35°C in an air atmosphere. Formulations utilizing Polyethylhexyl Acrylate should ensure minimal residual monomer content to prevent potential irritation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Polyethylhexyl Acrylate, alongside 125 other acrylates copolymers, safe for use in cosmetics under current practices and concentrations, provided it is formulated to be non-irritating. The polymer is not absorbed by the skin. Primary safety considerations involve ensuring low levels of residual monomer (2-ethylhexyl acrylate), which is recognized as an irritant and sensitizer; however, CIR reports confirm that cosmetic-grade polymers adequately address these monomer impurities. Its listing in the FDA's Inventory of Food Contact Substances also suggests approval for certain indirect food contact applications.
