This castor oil which is a mixture of saturated and unsaturated fatty acids has gained a reputation as the important bio-based raw material for industrial applications, medicines and in other technologies. This oil is extracted colorless to a very pale yellow liquid with a mild taste and mild odor.

In the era where environmental protection is of major concern for governments and industries, people are looking for renewable resources that help in sustainable development. Castor oil and castor oil products with their unique formulation and properties have been accepted worldwide as the potential replacement of the petroleum-based starting chemicals for the production of materials with a variety of properties. In the global market, there is a huge demand for this oil owing to its other special characteristics like non-competition with food, biodegradability, low costs, and eco-friendliness. The oil is currently used in sectors such as agriculture, food, plastic, rubber, paper, pharmaceuticals, inks, additives, biofuels, cosmetics, electronics, etc.

This oil contains 85 to 90 percent of Ricinoleic acid along with Oleic acid, Linoleic acid, Alpha-Linolenic acid, Palmitic acid, Stearic acid, Dihydroxystearic acid and others. The dominant ricinoleic acid and the presence of the three functional groups in the acid play a significant role in making castor oil highly beneficial for various uses. The presence of this ricinoleic acid and the other three functionalities contribute towards making the oil highly versatile for the production of castor-oil based products.

Apart from the industrial uses, there is also evidence of ricinoleic acid being useful for digestive issues.
