Description

Ricinoleic Acid CAS NO 61789-44-4 is a monounsaturated, 18-carbon fatty acid characterized by a hydroxyl group on the twelfth carbon, making it a unique and versatile oleochemical. This structural feature is responsible for its valuable properties as a reactive intermediate and a key building block in specialty synthesis. It is an essential raw material for manufacturers in the cosmetics, lubricants, polymers, and pharmaceutical industries seeking bio-based and functional ingredients.

Application

• Surfactant & Emulsifier Production: Serves as a key raw material for synthesizing sulfated castor oil (Turkey Red Oil) and other anionic surfactants used in textiles, leather processing, and agrochemical formulations.
• Polymer & Resin Intermediate: Used in the production of alkyd resins, polyamide adhesives (nylon 11), and bio-based polyesters, imparting flexibility and hydrophobicity.
• Cosmetic & Personal Care Ingredients: Employed in the manufacture of esters (e.g., methyl ricinoleate, butyl ricinoleate) which act as emollients, viscosity modifiers, and pigment wetting agents in creams, lotions, and makeup.
• Lubricant & Grease Formulation: Its polar structure makes it and its derivatives effective as friction modifiers and components in biodegradable lubricants, metalworking fluids, and lithium-based greases.
• Pharmaceutical & Chemical Synthesis: Functions as a chiral starting material or intermediate for synthesizing various compounds, including flavor & fragrance ingredients and medicinal agents.
• Plasticizer & Stabilizer: Used to produce derivatives that act as secondary plasticizers and stabilizers for PVC and other polymer systems.

Quality Control

Our Ricinoleic Acid is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, acid value, hydroxyl value, and iodine value. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C. Due to its hygroscopic (moisture-sensitive) nature and tendency to be easily oxidized (store under inert atmosphere), the container must be kept tightly sealed after each use to minimize exposure to air and moisture. Keep away from strong oxidizing agents.
