Castor OilsTraded & Blended | Lubricant, Emulsifiers, Pharmacutical |
Obtained from the seeds of Ricinius Commanis, a plant which is cultivated in several tropical areas of the world. The oil has a high percentage of Ricinoleic acid and a hydroxyl group on the 12th atom, which gives unique chemical and physical properties.
- Castor Oil NO1 - commercial, quality refined grade castor oil. Applications include: soaps, lubricants, sealants, pigment wetting, disinfectants, hydraulic fluids.
- Castor Oil BP - pharmaceutical grade castor oil. Applications include: pharmaceutical, cosmentics and personal care, polyurethane foams and resins.
- Hydrogenated castor oil - Esterified Castor Oil. Viscosity modifier, thickening agent, emulsifier, lubricant.
