Castor oil is obtained from the fruit seed of castor (Ricinus communis L.) a large shrub that grows mainly in India, Brazil and China. The seed has an oil content of 40-50%. The quality manly used is first pressed, known as fist special grade (FSG), it is a light-colored liquid, yellowish, with a characteristic odour and high viscosity.
It is the only oil containing fatty acid ricinoleic characterized by the presence of an OH group (more than 80%) which gives rise to the properties that make castor an exclusive oil.
Moreover the high reactivity of the OH group (hydroxyl) leads to a high range of products such as dehydrated castor oil, hydrogenated castor oil, 12-hydroxystearic acid, sebacic acid, ricinoleic acid. This is an oil wit flexibility and ductility and It is mainly used for the manufacturer of industrial resins, plastics, elastomers, dielectric, rubber products in general.
