Science
Mechanism of Action
Functioning as a film-forming agent, Polysilicone-5 is believed to create a breathable barrier on the skin's surface. This barrier may aid in moisture retention by reducing transepidermal water loss and could also offer protection against irritating external molecules. Beyond its protective qualities, it contributes to improved formulation aesthetics, imparting a smooth, silky skin feel and refining product texture.

Stability
No specific optimal pH range for Polysilicone-5's stability has been identified. However, polysilicones as a class are known for their high chemical stability, thermal resilience, and UV resistance, implying a broad stability profile under typical cosmetic conditions.
Safety
Safety Profile
The CIR Expert Panel concluded that Polysilicone-5 is safe when utilized as a surface coating for metal oxide particles. Crucially, the available data are insufficient to ascertain its safety profile for independent use in other cosmetic functions, preventing the determination of a maximum safe concentration. No specific SCCS opinion or FDA regulatory status is available for Polysilicone-5.
