Description

Ricinoleic Acid Ethyl Ester is a high-purity fatty acid ester derived from castor oil, serving as a versatile and reactive chemical intermediate. Its unique structure, featuring a hydroxyl group on the fatty acid chain, makes it a valuable building block for synthesizing specialized polymers, lubricants, and cosmetic ingredients. This product is essential for manufacturers in the personal care, polymer, and specialty chemical industries seeking to develop bio-based, high-performance formulations.

Application

• Polymer & Resin Synthesis: Acts as a reactive monomer or plasticizer in the production of polyurethanes, polyesters, and alkyd resins.
• Personal Care & Cosmetics: Used as an emollient, viscosity modifier, and carrier oil in creams, lotions, and lipsticks.
• Lubricant & Grease Formulation: Serves as a base stock or additive for bio-based lubricants, offering good low-temperature properties.
• Chemical Intermediate: A key starting material for the synthesis of surfactants, estolides, and other functional derivatives.
• Pharmaceutical Excipients: Employed as a penetration enhancer or solvent in topical drug delivery systems.
• Flavor & Fragrance Industry: Used in the synthesis of aroma chemicals and as a fixative.

Quality Control

Our Ricinoleic Acid Ethyl Ester is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and titration methods, to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) are provided with every shipment, and we support compliance with relevant standards such as REACH and FDA guidelines for specific applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C under an inert atmosphere (e.g., nitrogen) to prevent oxidation. Keep away from heat, sparks, and open flame. The container should be kept tightly sealed when not in use to minimize moisture absorption and contamination.
