Description

Ricinoleic Acid CAS NO 141-22-0 is a monounsaturated, 18-carbon fatty acid characterized by a hydroxyl group on the 12th carbon, making it a unique and versatile oleochemical. This bifunctional nature (carboxylic acid and hydroxyl group) is the key to its value, enabling its use as a reactive intermediate in the synthesis of specialty chemicals and polymers. It is an essential raw material for manufacturers in the cosmetics, lubricants, plastics, and pharmaceutical industries seeking sustainable and performance-driven ingredients.

Application

• Surfactants & Esters: Primary feedstock for the production of sodium ricinoleate (a surfactant) and various esters like methyl ricinoleate, used in soaps, detergents, and emulsifiers.
• Lubricants & Greases: Used to formulate biodegradable lubricants, cutting oils, and lithium-based greases, offering excellent viscosity and lubricity properties.
• Polymer & Plasticizer Synthesis: Serves as a monomer for polyesters and polyamides (nylon-11) and is a precursor for sebacic acid, a key component in plasticizers and engineering polymers.
• Cosmetics & Personal Care: Valued in formulations for its emollient and moisturizing properties, found in creams, lotions, and lipsticks.
• Pharmaceutical Intermediates: Utilized in the synthesis of certain prostaglandins and other active pharmaceutical ingredients (APIs).
• Coatings & Resins: Acts as a modifying agent in alkyd resins and coatings to improve flexibility and drying time.

Quality Control

Our Ricinoleic Acid is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, acid value, hydroxyl value, iodine value, and color. Our quality commitment aligns with industrial and specialty chemical standards, and we can support requirements for ISO, GMP, or REACH compliance as needed.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal quality. Keep away from strong oxidizers and heat sources.
