Science
Mechanism of Action
As a silicone-based copolymer, its dimethicone constituents impart a silky-smooth texture and a subtle sheen to the skin. It forms a protective, occlusive film that also functions as an emollient and skin conditioning agent, enhancing product spreadability and aiming for a lightweight, non-greasy skin feel. This ultra-thin film further aids in shielding the skin from external environmental stressors.

Stability
Exhibits good stability, typical of dimethicone components, which are generally chemically and physically inert. Related dimethicone polymers have demonstrated stability for at least 1 year under standard storage conditions.
Safety
Safety Profile
Safety data for this specific copolymer is currently deemed insufficient by the Cosmetic Ingredient Review (CIR) Expert Panel, particularly regarding manufacturing methods, impurities, and skin sensitization at maximum use concentrations. Furthermore, the Environmental Working Group (EWG) identifies this ingredient as a PFAS (Per- and polyfluorinated chemical), a class of chemicals flagged for potential health concerns including thyroid disruption, reproductive and developmental toxicity, and immunotoxicity in both humans and animals.
