Behenic acid (also docosanoic acid) is a carboxylic acid, the saturated fatty acid with formula C21H43COOH. In appearance, it consists of white to cream color crystals or powder with a melting point of 80 °C and boiling point of 306 °C.
At 9%, it is a major component of Ben oil (or behen oil), which is extracted from the seeds of the Ben-oil tree (Moringa oleifera). It is so named from the Persian month Bahman, when the roots of this tree were harvested.
Behenic acid is also present in some other oils and oil-bearing plants, including rapeseed (canola) and peanut oil and skins. It is estimated that one ton of peanut skins contains 13 pounds (5.9 kg) of behenic acid.
Commercially, behenic acid is often used to give hair conditioners and moisturizers their smoothing properties. It is also used in lubricating oils, and as a solvent evaporation retarder in paint removers. Its amide is used as an anti-foaming agent in detergents, floor polishes and dripless candles. Reduction of behenic acid yields behenyl alcohol.
