Behenoxy Dimethicone

Silicone

What is Behenoxy Dimethicone?

Behenoxy Dimethicone is a synthetic silicone polymer, chemically a dimethicone modified by attachment of a behenoxy group from behenic acid, creating a longer-chain structure for enhanced performance. Primarily used in hair care products like conditioners and styling aids, it also appears in skin creams, lotions, and serums within the emollient and conditioning category. In formulations, it works by spreading evenly to form a thin, flexible film on the skin or hair surface. This film lubricates, reduces friction for better slip during application, and mimics the protective barrier of natural sebum without adding oiliness or tackiness. Its hydrophobic nature helps repel water while allowing some permeability, aiding in surface hydration maintenance. Commonly incorporated at low levels, it contributes to product stability and sensory appeal.
