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. 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.[1]
