What it is
Caprylyl Trimethicone is a low-viscosity silicone fluid used in cosmetics as an emollient and conditioning agent. It gives formulas a light, silky slip and a non-greasy, smooth afterfeel, and it can aid the spreadability of pigments and UV filters. In sunscreens it is valued for helping the product glide on evenly while keeping a lightweight finish.
