Ricinoleic acid (12-hydroxy-9-cis-octadecenoic acid) is an unsaturated omega-9 fatty acid that naturally occurs in mature Castor plant (Ricinus communis L., Euphorbiaceae) seeds or in sclerotium of ergot (Claviceps purpurea Tul., Clavicipitaceae). About 90% of the fatty acid content in castor oil is the triglyceride formed from ricinoleic acid. Ricinoleic acid is manufactured for industries by saponification or fractional distillation of hydrolyzed castor oil. The zinc salt is used in personal care products, such as deodorants.
