Arachidic acid, also called eicosanoic acid, is the saturated fatty acid with a 20-carbon chain. It is as a minor constituent of cupuaçu butter (7%),[2] peanut oil (1.1%–1.7%),[3] corn oil (3%),[4] and cocoa butter (1%).[5]

Typical Fatty acid composition (%):[6] 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.
