Castor Oil Pharmaceutical Excipient Manufacturer in India
Castor Oil is a natural vegetable oil obtained from the seeds of Ricinus communis. It is widely used in pharmaceutical formulations as an excipient, emollient, vehicle, lubricant, and formulation aid.
Pharmaceutical-grade Castor Oil is valued for its distinctive fatty-acid composition, high viscosity, and good solvency characteristics for certain active and inactive ingredients. It can be used in topical, oral, and other pharmaceutical formulation systems depending on the applicable grade and formulation requirements.
Castor Oil Pharmaceutical Excipient Overview
Castor Oil consists predominantly of ricinoleic acid glycerides, which provide its characteristic physical and chemical properties. The oil is generally a clear to pale-yellow, viscous liquid and is practically insoluble in water.
It is used in pharmaceutical formulations where an oily vehicle, emollient, lubricant, or solubilizing/formulation aid is required.
