Castor Oil, also known as Ricinus Oil is like most other fats, a triglyceride of fatty acid. However, it is a unique fat in that it contains 87-90% ricinoleic acid cis-12-hydroxyoctadec-9-enoic acid, a resource of an eighteen carbon hydroxylated fatty acid with one double bond. Castor Oil is recovered from castor beans by use of hydraulic presses in continuous mechanical screw expellers, followed by solvent extraction. This yields castor pomace with about 1-2% residual content. The castor pomace has a protein content of about 3.5% and it is mostly used as a fertilizer
