Science
Mechanism of Action
As a polymer, Polyethylacrylate operates by forming a cohesive film upon application to the skin. This film-forming action aids in binding other ingredients together and can create a smoother surface appearance. Its polymeric nature also contributes significantly to the product's rheology and stability, influencing its texture and spreadability.

Stability
This polymer exhibits solubility in a range of organic solvents, including THF, hexanes (for lower molecular weights), toluene, and chloroform. It tends to precipitate in ethanol and methanol when these solvents contain 10-15% water. While certain copolymers incorporating ethyl acrylate can be pH-responsive, specific optimal pH ranges for the stability of the Polyethylacrylate homopolymer in cosmetic formulations have not been detailed in current research.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined Polyethylacrylate to be safe for cosmetic use, provided it is formulated to prevent irritation. It falls under the broader classification of acrylates copolymers, which the CIR Panel generally considers safe when formulated to be non-irritating. While a related copolymer showed no irritation at 3% and no sensitization at 5% in a 70% mixture, specific maximum safe concentrations for Polyethylacrylate as a standalone ingredient were not established in the available data. The weight of evidence for potential skin, eye, or lung irritation specifically for Polyethylacrylate remains unknown or unassessed by CIR.

Verdict
Polyethylacrylate serves as a functional binding and film-forming agent, deemed safe with restrictions when properly formulated, but comprehensive clinical efficacy and detailed safety data for specific skin concerns are currently limited.
