100% Pure Castor Oil ACS Grade

Product Overview

100% Pure Castor Oil ACS Grade is a high-purity triglyceride derived from Ricinus communis seeds, conforming to ACS (American Chemical Society) reagent standards. This product exhibits a pale yellow to colorless appearance, mild odor, and a high viscosity profile that supports demanding industrial and pharmaceutical formulations. With a boiling range around 313°C and a flash point of 232°C, it demonstrates thermal stability suitable for use as a carrier, solvent, and functional ingredient in lubricant and cosmetic matrices. The oil presents a density near 0.961 g/mL at 25°C and a molecular weight of 875.00 g/mol, reflecting its long-chain fatty acid composition dominated by ricinoleic acid, which contributes to unique lubricant, moisturizing, and plasticizing properties in end applications. Its low water content (<0.15%) and controlled impurity profile support compatibility with a wide range of formulation chemistries, while compliance to ACS Reagent Grade and USP-NF Monographs underscores its reliability for quality-critical processes.

This ACS-grade castor oil is suitable for industrial and pharmaceutical contexts requiring a consistent supply of high-purity castor oil with well-characterized physical properties. It can serve as a baseline ingredient for lubricants, cosmetic formulations, pharmaceutical excipients, biodiesel feedstocks, and as a plasticizer additive in flexible plastics, where viscosity, stability, and fatty-acid composition play pivotal roles in performance and processing. The product is produced and tested under stringent quality controls to meet established tolerances, helping formulators achieve reproducible results across batches.

Safety Precautions

Store in a cool, dry place away from direct sunlight, using containers made of HDPE or glass to avoid contamination. Maintain storage temperatures below 25°C and handle with appropriate PPE, including gloves and eye protection, to prevent skin and eye irritation. Keep away from strong oxidizing agents and ensure proper ventilation during handling to minimize exposure to vapors.

Adhere to SDS guidance: the product is labeled with a WARNING signal word and poses Eye Irrit. 2 and Skin Irrit. 2 hazards (H319 and H315). In case of contact with eyes, rinse cautiously with water for several minutes; for skin exposure, wash with soap and water and seek medical advice if irritation persists. Inhalation should be moved to fresh air, and ingestion should be rinsed from the mouth with medical attention if symptoms occur. Transport is UN 3082, Environmentally hazardous substance, liquid, n.o.s., Class 9, PG III.
