Behenic acid comes from the ben oil tree, Moringa oleifera

Behenic acid (also docosanoic acid) is a normal 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.

Contents

Sources

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.[2]

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.[3]

Properties

As a dietary oil, behenic acid is poorly absorbed. In spite of its low bioavailability compared with oleic acid, behenic acid is a cholesterol-raising saturated fatty acid in humans.[4]

Uses

Commercially, behenic acid is often used to give hair conditioners and moisturizers their smoothing properties.[3] Also used in lubricating oils, as solvent evaporation retarder in paint removers. Amide as anti-foam in the manufacturing of detergents, in floor polishes and dripless candles. Reduction of behenic acid yields behenyl alcohol.

Pracaxi oil (from the seeds of Pentaclethra macroloba) is a natural product with one of the highest concentrations of behenic acid, and is used in hair conditioners.
