- 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.

| Hazard Information | Back Directory | [Chemical Properties]
white flakes or powder | [Production Methods]
Hydrogenated castor oil is prepared by the hydrogenation of castor
oil using a catalyst. | [Pharmaceutical Applications]
Hydrogenated castor oil is a hard wax with a high melting point
used in oral and topical pharmaceutical formulations.
In topical formulations, hydrogenated castor oil is used to
provide stiffness to creams and emulsions. In oral formulations,
hydrogenated castor oil 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 is additionally used to lubricate the die
walls of tablet presses; and is similarly used as a lubricant in
food processing.
Hydrogenated castor oil is also used in cosmetics. | [Safety]
Hydrogenated castor oil is used in oral and topical pharmaceutical
formulations and is generally regarded as an essentially nontoxic
and nonirritant material.
Acute oral toxicity studies in animals have shown that
hydrogenated castor oil is a relatively nontoxic material. Irritation
tests with rabbits show that hydrogenated castor oil causes mild,
transient irritation to the eye.
LD50 (rat, oral): >10 g/kg | [storage]
Hydrogenated castor oil is stable at temperatures up to 1508℃.
Clear, stable, chloroform solutions containing up to 15% w/v of
hydrogenated castor oil may be produced. Hydrogenated castor oil
may also be dissolved at temperatures greater than 908℃ in polar
solvents and mixtures of aromatic and polar solvents, although the
hydrogenated castor oil precipitates out on cooling below 908℃.
Hydrogenated castor oil should be stored in a well-closed
container in a cool, dry place. | [Incompatibilities]
Hydrogenated castor oil is compatible with most natural vegetable
and animal waxes. | [Regulatory Status]
Accepted in the USA as an indirect food additive. Included in the
FDA Inactive Ingredients Database (oral capsules, tablets, and
sublingual tablets).
Included in nonparenteral medicines licensed in the UK. Included
in the Canadian List of Acceptable Non-medicinal Ingredients. |
