Science
Mechanism of Action
Stearyl Methacrylate/Perfluorooctylethyl Methacrylate Copolymer functions primarily by forming a cohesive film on the skin's surface. The distinctive fluorinated segments within its polymer chains contribute to both water-repelling (hydrophobic) and oil-repelling (oleophobic) characteristics. This dual-repellent nature enables it to create a protective barrier, potentially enhancing product longevity and resistance to environmental factors. Additionally, it helps control the texture and flow of cosmetic products by modulating their viscosity.

The Formula
Formulation
Stability
Due to its inherent hydrophobic and oleophobic properties, derived from its fluorinated components, this ingredient is optimally soluble in oil-based systems or specific organic solvents rather than aqueous solutions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel, reviewing this ingredient as part of 'fluorinated-side-chain polymers,' concluded that the available data were insufficient to determine its safety. No specific safety status from the FDA or SCCS for cosmetic use has been identified for this exact ingredient.
