Formula IngredientEmollientBehenic Acid
INCI: Docosanoic Acid
Behenic acid (INCI: Docosanoic Acid) is a long-chain C22 saturated fatty acid naturally found in plant oils such as moringa (ben oil), rapeseed, and peanut oil. In cosmetics it functions primarily as an emollient and skin-conditioning agent, softening the skin surface by filling gaps between skin cells and reducing transepidermal water loss. It also serves as an emulsifier, opacifying agent, and surfactant/cleansing co-agent, contributing texture, slip, and stability to formulations.
