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

Typical Fatty acid composition (%):^[5] 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.
