What it is
Cetyl Dimethicone is a dimethicone derivative carrying a long cetyl alkyl group, giving it both silicone and waxy fatty character. In formulas it works as an emollient and conditioning agent that smooths skin and improves spreadability and after-feel. It can also help stabilize emulsions, particularly water-in-silicone systems.
Safety & warnings
Silicone-based emollients of this type are generally well tolerated, non-sensitizing for most users, and considered low in irritation potential.
Origin & sourcing
