Stearyl Dimethicone is a silicone-based emollient derived from dimethicone with a stearyl (C18) fatty chain attached. This combination provides both the silky, smooth properties of silicones and the occlusive, moisturizing effect of long-chain fatty alcohols. It is widely used in personal care and cosmetic formulations to improve spreadability, skin and hair feel, and product stability.
