Behenic acid, also known as docosanoic acid, is a long-chain saturated fatty acid consisting of a 22-carbon backbone. It occurs naturally in plant-derived oils including rapeseed, peanut, and moringa seed oils, as well as in some animal fats. Due to its high melting point, it is widely employed in the formulation of cosmetics, waxes, lubricants, and emulsifiers. In the food industry, it appears in trace amounts in certain vegetable oils and is regarded as safe for human consumption. Behenic acid exhibits typical carboxylic acid reactivity, forming salts, esters, and amides, and serves as a precursor in the synthesis of behenyl alcohol and other derivatives used in personal care products.
