Hydrogenated Castor Oil

Hydrogenated Castor Oil (HCO), also known as castor wax, is a solid, waxy derivative obtained by the hydrogenation of castor oil. It appears as a white to off-white, brittle, wax-like solid with a mild odor. The hydrogenation process saturates the unsaturated bonds in castor oil’s fatty acids, resulting in a product with enhanced melting point, oxidative stability, and hardness. HCO retains excellent emollient and lubricating properties while exhibiting improved resistance to oxidation and rancidity. It is widely used in cosmetics, pharmaceuticals, plastics, coatings, and industrial applications for its functional versatility and compatibility.
