Bis-Stearyl Dimethicone
What Bis-Stearyl Dimethicone is & what it does
Bis-Stearyl Dimethicone is a silicone modified with two long-chain stearyl groups, combining the smooth slip of a dimethicone with the waxy, conditioning feel of a fatty alcohol derivative. In creams and sunscreens it acts as an emollient and texture enhancer, giving products a silky glide and helping form a soft, water- resistant film on the skin surface. It is a wax-like solid at room temperature, so it can also help thicken and stabilize anhydrous or oil-rich formulas.
