Hydrogenated Castor Oil Powder occurs as a fine, almost white or pale yellow powder or flakes.
The PhEur 6.0 describes Hydrogenated Castor Oil Powder as the oil obtained by hydrogenation of virgin castor oil.
Hydrogenated Castor Oil Powder consists mainly of the triglyceride of 12-hydroxystearic acid.
Hydrogenated Castor Oil Powder — also called HCO or castor wax — is a hard, white, opaque vegetable wax.
Hydrogenated Castor Oil Powder's resistance to moisture makes it useful in many coatings, greases, cosmetics, polishes and similar applications.
The wax is created by hydrogenating pure liquid castor oil, which is obtained from castor beans.
Hydrogenated Castor Oil Powder is heated under extreme pressure using a nickel catalyst during the hydrogenation process.
Afterward, the hydrogen creates saturated molecules of castor wax, which gives the oil a higher melting point that allows it to remain solid at room temperature.
After hydrogenation, Hydrogenated Castor Oil Powder becomes hard and brittle to the touch.
Hydrogenated Castor Oil Powder is prepared by the hydrogenation of castor oil using a catalyst.
Uses
Greases: Lithium- and Calcium hydroxystearates dispersed in base oil to make multipurpose greases having higher dropping points, hardness, better rust-proofing, lubricity and durability than stearates.
Other lubricants: metal drawing lubes, PVC lubricants for PVC pipes, profiles, sheets, pharma tabletting, metal powders, ceramics.
cosmetics: HCO of different melting points used in lipsticks, deodorant and antiperspirant sticks, cosmetic creams.
slip additive in inks, paints, plastics (PE).
dispersing agent in plastic colour master batches, carbon papers, inks.
flow control and dispersing additive in powder coatings, hot-melt adhesives and sealants.
shoe polishing, furniture polishing creams.
Pharmaceutical Applications
Hydrogenated Castor Oil Powder is a hard wax with a high melting point used in oral and topical pharmaceutical formulations.
In topical formulations, Hydrogenated Castor Oil Powder is used to provide stiffness to creams and emulsions.
In oral formulations, Hydrogenated Castor Oil Powder is used to prepare sustained-release tablet and capsule preparations; the hydrogenated castor oil may be used as a coat or to form a solid matrix.
