what is ?)(
At 9%, it is a major component of ben oil (or behen oil), which is extracted from the seeds of the drumstick 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.
