Castor oil

Castor Oil is a vegetable oil extracted from the seeds of Ricinus communis and widely used in pharmaceutical and laboratory applications as a solvent, emulsifier, lubricant, and active ingredient in various formulations.

🏭⚗️ Production
Castor oil is obtained from the seeds of the castor plant through mechanical pressing or solvent extraction, followed by purification processes to remove impurities. The refined oil is suitable for incorporation into pharmaceutical and cosmetic products due to its high purity and consistent properties.

🔬 Properties
Castor oil is a clear to pale yellow viscous liquid with a mild odor. It is insoluble in water but soluble in most organic solvents. The oil contains a high proportion of ricinoleic acid, which provides emollient, lubricating, and anti-inflammatory properties, making it valuable in topical and oral formulations.

🧪 Applications
In pharmaceutical formulations, castor oil is used as a solvent in injectable preparations, an emulsifier in creams and ointments, a lubricant in tablet and capsule production, and a laxative in oral formulations. It also serves as a penetration enhancer and carrier for active ingredients in topical applications. In laboratory settings, castor oil is employed as a medium for biochemical studies, in the preparation of nanoparticles and lipid-based formulations, and as a component in experimental models requiring a viscous, biocompatible oil.

⚠️ Safety
Castor oil is generally recognized as safe for pharmaceutical and laboratory use when applied correctly. Excessive oral intake may cause gastrointestinal effects such as diarrhea, cramping, and nausea. Topical application can occasionally lead to skin irritation or allergic reactions in sensitive individuals. It should be stored in tightly closed containers, away from heat and light, to maintain stability and purity.
