Arachidic acid, also known as eicosanoic acid, is a saturated fatty acid with a 20-carbon chain. It is a minor constituent of cupuaçu butter (7%),[2] perilla oil (0–1%),[3] peanut oil (1.1–1.7%),[4] corn oil (3%),[5] and cocoa butter (1%).[6] It also constitutes 7.08% of the fats from the fruit of the durian species Durio graveolens.[7]
Its name derives from the Latin arachis—peanut. It can be formed by the hydrogenation of arachidonic acid.
Reduction of arachidic acid yields arachidyl alcohol.
Arachidic acid is used for the production of detergents, photographic materials and lubricants.
