100% Pure Castor Oil ACS Grade

Product Overview

100% Pure Castor Oil ACS Grade is a high-purity triglyceride derived from Ricinus communis seeds, manufactured to meet or exceed American Chemical Society (ACS) reagent specifications. This premium grade ensures minimal impurities, making it the preferred choice for critical laboratory analysis, chemical synthesis, and high-precision industrial formulations. Distinct from technical grades, ACS Grade Castor Oil offers a strictly controlled profile for viscosity, specific gravity, and acid value.

Characterized by a high concentration of ricinoleic acid, this oil exhibits unique chemical properties, including high viscosity (approx. 850 cP at 25°C) and excellent thermal stability with a flash point of 232°C. It serves as a superior renewable building block for polyurethanes, a plasticizer in coatings, and a bio-based lubricant in mechanical systems requiring high lubricity. Its solubility in alcohols and insolubility in water make it versatile for solvent extraction and phase separation processes.

Safety & Handling

Store in a cool, dry area away from direct sunlight and strong oxidizing agents. Keep containers tightly closed when not in use to prevent oxidation. Recommended storage temperature is below 25°C. Use appropriate Personal Protective Equipment (PPE), including safety glasses and chemical-resistant gloves, when handling bulk quantities.

Safety Data Information: Class 9 Miscellaneous Hazardous Material (UN 3082, Environmentally hazardous substance, liquid, n.o.s.). Causes serious eye irritation (Category 2A) and skin irritation (Category 2). Wash thoroughly after handling. Refer to the Safety Data Sheet (SDS) for detailed spill cleanup and emergency procedures.
