Castor Oil Derivatives

Castor seed harvested from field is dried till the pods open. Seeds are hulled by using de-hullers or by hand to remove the seed from the pod. Extraction of oil from castor seeds is done in a manner similar to that for most other oil seeds. The ripe seeds are allowed to dry. These seeds are cleaned, cooked and dried prior to extraction. Cooking is done to coagulate protein (necessary to permit efficient extraction). The first stage of oil extraction is pre-pressing, using a high pressure screw press – called the expeller. Extracted oil is filtered and the material removed from the oil is fed back along with fresh material. The Indian variety of castor has an oil content of 42-48%.

Castrol oil is unique among vegetable oils and uniqueness is derives from the presence of a hydroxyl fatty acid known as ricinoleic acid, which constitute around 90% of the total fatty acids of the oil. Castor Oil is also distinguished from other vegetable oils by its high specific gravity, thickness and hydroxyl value.

Castor oil is used either in its crude form or in the refined hydrogenated form. Typically, 65% of it is processed (about 28% is refined, 12% is hydrogenated, 20% is dehydrated and the balance 5% is processed to manufacture other derivatives). The major derivatives of castor oil used in the industry are hydrogenated castor oil (HCO), Dehydrated castor oil (DCO) and Sebacic acid etc.
Castor oil is used as a raw material in the manufacture of a number of chemicals, which are used in the manufacture of surfactants, specialty soaps, surface coatings, cosmetics & personal care products, pharmaceuticals, perfumes, plasticisers, greases & lubricants and specialty rubber etc.

Though India is meeting most of the world's requirement of castor oil but we are not capitalizing it. India still continues to export the oil rather than add value to it. We buy back our own castor oil as formulated products and derivatives at many times the price of the oil.

Export of castor oil by India

India is the first country in the world to exploit commercial scale in this crop. Major markets include European Union, USA, Japan and now China and Thailand. India is largest exporter of castor oil. India exports more than 80% of total castor seed output in the form of oil.

Although India is the world’s largest producer, consumer and exporter of castor oil, it has not been able to effectively leverage that dominant position for obtaining better prices abroad because of poor marketing infrastructure, inadequate investment in research & development and unhealthy competition among exporters.
