HYDROGENATED CASTOR OIL (Castor Wax) accounts for the largest single use of castor oil for a standard commodity. In the hydrogenation process, the ricinoleic acid becomes fully saturated and forms a viscous wax-like product with a high melting point of 86°C, which makes HCO valuable in resin and polymer mixtures. The HCO is insoluble in water and most organic solvents, but it is soluble in hot solvents. It is this insolubility that makes HCO valuable to the lubricants markets. It is water resistant while retaining lubricity , polarity and surface wetting properties. The early use of HCO in greases was to improve texture and oxidative stability of greases exposed to high sheer stress with little effect on structure or consistency. The introduction of HCO opened up a whole new world of possibilities to the formulator.

DEHYDRATED CASTOR OIL is obtained from the seeds of Ricinus Communis, which is a pale yellow, viscous, oily liquid insoluble in water. It contains more than 87% of a unique hydroxy fatty acid.

CASTOR OIL is a vegetable oil pressed from castor beans. It is a colourless to very pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm3. It includes a mixture of triglycerides in which about 90% of fatty acids are ricinoleates. Key Application: Lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold-resistant plastics, waxes and polishes.
