POLYSILICONE-15

About this ingredient

Polysilicone-15 is a high-molecular-weight silicone polymer that functions as a film-forming and skin-conditioning agent in cosmetics. It creates a durable, water-resistant protective layer on the skin surface, enhancing product substantivity and wear resistance—particularly beneficial in waterproof sunscreens, long-wear foundations, and aquatic cosmetics. It imparts a smooth, non-greasy feel and improves formula stability.
