Castor Oil & Castor Oil Derivatives


While castor oil by itself is used in diverse applications, chemical derivatives of castor oil find numerous uses in industrial applications and their domains of use are increasing rapidly.

This section of CastorOil.in provides info & resources for castor oil & castor oil derivatives/chemicals.

Castor Oil Characteristics & Facts

·         Castor oil consists almost entirely of the triglycerides ricinoleic acid

·         It ranges in colour from colourless to greenish

·         It is a viscous & non-drying liquid

·         It has a faint odour

·         It has a slightly acrid taste, and a nauseating after-taste

·         Castor oil does not become excessively viscous at low temperatures. It performs well as a high-temperature lubricant, well suited for use in jet, diesel, and race car engines.
