Hydrogenated Castor Oil Powder is a hydrogenated form of castor oil that is insoluble in water.
Hydrogenated Castor Oil Powder has been used as an antimicrobial agent for various detergent compositions, pharmaceutical preparations, and topical formulations.
Hydrogenated Castor Oil Powder has also been used as a polymerization aid for the production of insoluble polymers, including polyurethane elastomers.
The hydrogenation process changes the chemical composition by increasing the number of hydroxyl groups and reducing the number of unsaturated bonds.
These changes can affect how the molecule interacts with other molecules and its solubility in water.
Low energy activation energies have been reported for Hydrogenated Castor Oil Powder compared to other oils such as olive or sunflower oils.
Hydrogenated Castor Oil Powder, with the CAS number 8001-78-3, is a semi-solid, waxy substance derived from the Hydrogenated Castor Oil Powder, which is extracted from the seeds of the Ricinus communis plant.
This modification process enhances its stability and alters its physical properties, making Hydrogenated Castor Oil Powder less prone to oxidation and rancidity.
Hydrogenated castor oil is characterized by its high viscosity, emulsifying properties, and ability to act as a thickening agent.
Hydrogenated Castor Oil Powder is commonly used in various applications, including cosmetics, pharmaceuticals, and food products, where it serves as an emulsifier, stabilizer, or lubricant.
Additionally, Hydrogenated Castor Oil Powder is valued for its skin-conditioning properties in personal care formulations.
Hydrogenated Castor Oil Powder is generally recognized as safe for use in food and cosmetic applications, although its specific regulatory status may vary by region.
Overall, Hydrogenated Castor Oil Powder is a versatile ingredient that combines the beneficial properties of castor oil with enhanced stability and functionality.
Hydrogenated Castor Oil Powder is a wax-like hydrogenated derivative of castor oil.
Hydrogenated Castor Oil Powder has many cosmetic and industrial applications.
Hydrogenated Castor Oil Powder is a white, brittle, insoluble wax flake with a high melting point.
Hydrogenated Castor Oil Powder is highly resistant to water and oils and finds many applications in protective coatings and sealers.

Hydrogenated Castor Oil Powder occurs as a fine, almost white or pale yellow powder or flakes.
The PhEur 6.0 describes hydrogenated castor oil 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, the oil becomes hard and brittle to the touch.
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.
Hydrogenated Castor Oil Powder is additionally used to lubricate the die walls of tablet presses; and is similarly used as a lubricant in food processing.
Hydrogenated Castor Oil Powder is also used in cosmetics.
