✦ Synopsis

The presence of a hydroxyl group, in addition to an olefinic linkage, in the predominating fatty acid of castor oil gives this vegetable oil many unique and interesting properties. It has been known for a long time as an industrial fluid and also has reputation for its medical use. Moreover, castor oil and its chemical derivatives are used as raw materials for different types of products in many chemical industries.

Castor oil is a topic of interest to the chemical industry for several reasons: intense international awareness of biodegradability of castor oil and its derivatives and reduction in the supply of petroleum, a non-renewable source, used for the manufacture of several oleochemicals. Commercial application of castor oil in the preparation of surface coatings, printing ink, surface active agents, plasticizers is very wellknown. But the recent trend consists of utilization of castor oil and its derivatives in the formulation of various lubricants and greases [1,2].
