100% Pure Castor Oil

Product Overview

100% Pure Castor Oil (Technical Grade) is a high-viscosity vegetable oil extracted from the seeds of Ricinus communis. Distinguished by its high concentration of ricinoleic acid, this triglyceride offers unique chemical properties, including high molecular weight and specific gravity, making it a critical raw material for industrial formulations. It appears as a clear to pale yellow liquid with a mild characteristic odor.

This technical grade material serves as a primary feedstock for the production of polyols in the polyurethane industry, a bio-based lubricant for machinery, and a plasticizer in coatings and adhesives. Its hydroxyl functionality allows for specific chemical modifications, rendering it essential for the synthesis of surfactants, greases, and bio-polymers. The product is manufactured under strict quality control to ensure low impurity profiles, consistent viscosity (900–1000 cP), and compatibility with standard industrial processing equipment.

Key Properties

Common Applications

• Polyurethane Manufacturing: Acts as a natural polyol feedstock for rigid and flexible foams, coatings, and adhesives due to its hydroxyl functionality.
• Industrial Lubrication: utilized in high-temperature greases and hydraulic fluids where shear stability and high viscosity are required.
• Coatings & Paints: Functions as a plasticizer and drying oil in lacquers, varnishes, and protective coatings to improve flexibility and adhesion.
• Chemical Synthesis: Raw material for the production of sebacic acid, undecylenic acid, and various surfactants.
• Release Agents: Effective mold release agent for plastics and rubber processing.

Safety & Handling

Store in a cool, dry, well-ventilated area away from direct sunlight and strong oxidizing agents. Recommended storage containers include HDPE or glass. Although Castor Oil is a vegetable derivative, standard industrial hygiene practices should be observed. Wear appropriate Personal Protective Equipment (PPE), including safety glasses and gloves, during handling to prevent skin and eye contact.

Refer to the Safety Data Sheet (SDS) for detailed health and safety information. In case of eye contact, rinse immediately with plenty of water. If spilled, contain the material to prevent entry into waterways, as oil can pose environmental risks to aquatic life.

Benefits

• High Purity Profile: Consistent assay ensures reliable reaction rates in polymer synthesis.
• Bio-Based Feedstock: Renewable alternative to petrochemical lubricants and polyols.
• Thermal Stability: High flash point and viscosity index support performance in elevated temperatures.
• Versatile Solvency: Compatible with a wide range of organic solvents and polar compounds.
