Science
Mechanism of Action
This copolymer functions by depositing a continuous, non-occlusive polymeric film on the skin's surface. This structured film imparts beneficial properties such as improved adhesion, hydrophobicity, and resistance to physical wear or environmental factors, thereby enhancing the functional performance and longevity of cosmetic products.

Formulation
Stability
The constituent monomers (Cyclohexyl Methacrylate and 2-Ethylhexyl Methacrylate) typically require stabilization with inhibitors (e.g., MEHQ) and the presence of oxygen for inhibitor effectiveness. Storage should be maintained below 35 °C. These monomers exhibit heat sensitivity and incompatibility with strong acids, strong oxidizing agents, and strong bases. Information regarding the optimal pH range for the copolymer's stability within a finished formulation is not available.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel included Cyclohexyl Methacrylate/Ethylhexyl Methacrylate Copolymer in its assessment of acrylates copolymers, concluding it is safe for use in leave-on products at concentrations up to 25%. While the monomer Cyclohexyl Methacrylate was deemed safe for nail products with specific labeling to avoid skin contact, the broader assessment of methacrylate ester monomers indicates generally low acute toxicity.
