Hydrogenated Castor Oil

Whatsapp Order

Hydrogenated Castor Oil, also known as castor wax, is a hard, brittle, and high-melting-point wax derived by the hydrogenation of pure castor oil. This white to off-white, odorless substance is non-toxic and insoluble in water but dispersible in surfactant systems. Its primary component is hydrogenated ricinoleic acid triglyceride, and it is prized for its excellent lubricating, emulsifying, thickening, and consistency-enhancing properties.

Due to its stability, non-reactivity, and film-forming capability, Hydrogenated Castor Oil is widely used in cosmetics, personal care, pharmaceuticals, industrial lubricants, coatings, plastics, and more. It improves product texture, enhances emulsion stability, and provides moisture retention in skincare applications.
