Sodium Behenate
What is Sodium Behenate?
Sodium behenate is the sodium salt of behenic acid, a long-chain saturated fatty acid (docosanoic acid) typically sourced from vegetable oils such as rapeseed or peanut. In cosmetics, it appears mainly in rinse-off products like bar soaps, syndet bars, body washes, and shampoos. As an anionic surfactant, it reduces surface tension between water and oils, enabling the formation of micelles that encapsulate dirt, sebum, and impurities for easy rinsing. This mechanism supports cleansing without stripping the skin's natural barrier excessively. It also aids emulsification, helping blend oil and water phases in formulations, and contributes to product texture by providing opacity control in some cleansers. Its mild profile makes it suitable for everyday personal care items.
