Behenyl Dimethicone
What is Behenyl Dimethicone?
Behenyl Dimethicone is a synthetic organosilicon compound, formed by attaching a long-chain behenyl group (derived from behenyl alcohol, a C22 fatty alcohol) to dimethicone, which is a type of polydimethylsiloxane. This alkyl modification improves its lipophilicity and substantivity compared to plain dimethicone. Commonly found in skincare formulations such as creams, lotions, serums, and hair conditioners within the emollient and conditioning category, it works by spreading evenly to create a thin, flexible occlusive film. This barrier reduces transepidermal water loss while allowing skin to breathe, enhancing product slip and improving overall sensory experience without heaviness or residue. Its chemical stability resists oxidation, making it suitable for various pH levels and compatible with water- and oil-based systems.
