Description

Castor Oil is a versatile, naturally occurring vegetable oil derived from the seeds of the *Ricinus communis* plant, prized for its high concentration of ricinoleic acid. This unique fatty acid profile imparts exceptional properties, including high viscosity, excellent lubricity, and solubility in alcohols, making it a critical raw material for numerous industrial syntheses. It is an indispensable ingredient for manufacturers in the cosmetics, pharmaceuticals, lubricants, plastics, and coatings industries seeking sustainable and high-performance bio-based solutions.

Application

• Cosmetics & Personal Care: Acts as an emollient, moisturizer, and viscosity modifier in lipsticks, soaps, shampoos, and skin creams.
• Pharmaceuticals: Used as a component in topical ointments, capsules, and as a stimulant laxative (when hydrolyzed to ricinoleic acid).
• Industrial Lubricants & Greases: Serves as a base or additive in high-performance, biodegradable lubricants, hydraulic fluids, and cutting oils.
• Polymer & Plasticizer Production: A key renewable feedstock for manufacturing sebacic acid, nylon-11 (Rilsan), and polyurethane coatings.
• Surface Coatings: Used in the formulation of alkyd resins for paints, varnishes, and lacquers to enhance flexibility and drying time.
• Textile & Leather Processing: Functions as a softening agent, dye leveler, and finishing agent for textiles and leather goods.
• Food Industry: Employed as a release agent, anti-foaming agent, and as a component in food-grade packaging (where compliant with FCC standards).

Quality Control

Our Castor Oil is sourced and processed under stringent quality management systems. We offer various grades, including Technical, USP, and FCC, each meeting specific industry requirements. Every batch is tested for critical parameters such as acid value, saponification value, hydroxyl value, iodine value, and fatty acid composition. Certificates of Analysis (COA) documenting purity, identity, and compliance are available upon request to ensure your quality assurance and regulatory needs are fully met.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Avoid prolonged exposure to extreme heat, moisture, and oxidizing agents to maintain product integrity and prevent rancidity.
