Arachidic acid,also known asicosanoic acid,is a saturatedfatty acidwith a 20-carbon chain. It is a minor constituent ofcupuaçubutter (7%),[2]perilla oil(0–1%),[3]peanut oil(1.1–1.7%),[4]corn oil (3%),[5]andcocoa butter(1%).[6]The salts and esters of arachidic acid are known asarachidates.
Its name derives from the Latinarachis—peanut. It can be formed by thehydrogenationofarachidonic acid.
Reduction of arachidic acid yieldsarachidyl alcohol.
Arachidic acid is used for the production of detergents, photographic materials and lubricants.
