What Glyceryl Undecyl Dimethicone is & what it does

Glyceryl undecyl dimethicone is a silicone-based ingredient that combines a dimethicone (silicone) backbone with a glyceryl and fatty-chain modification, making it a hybrid emollient and conditioning agent. In a formula it typically provides a smooth, silky slip, improves spreadability, and can help give sunscreens and creams a non-greasy finish. Modified silicones like this are often chosen to balance silicone glide with better compatibility with water-based systems. No specific concerns are flagged for this ingredient here.
