Refined Castor Oils
Vertellus supplies an unsurpassed variety of castor oil grades. Application choice is dictated by acid value, moisture level, color and purity.
Castor oil is a triglyceride of fatty acids. Approximately 90% of the fatty acid content is ricinoleic acid which is an 18-carbon acid having a double bond in the 9-10 position and a hydroxyl group on the 12th carbon. Its remarkably constant composition, hydroxyl functionality and unsaturation make it uniquely versatile as a naturally occurring compound.
Castor oil is a renewable, sustainable natural oil polyol for urethane reactions as well as a starting point for a variety of derivative chemistries.
