Description

(9Z,12Z)-9,12-Octadecadienoic Acid (2S)-2,3-Dihydroxypropyl Ester is a structured lipid derivative of linoleic acid, a key ω-6 fatty acid. This compound is valued for its amphiphilic properties, combining the hydrophobic fatty acid chain with a hydrophilic glycerol backbone, making it a versatile intermediate and functional ingredient. It is primarily sought by manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries for use in drug delivery systems, lipid-based formulations, and as a biochemical building block.

Application

• Pharmaceutical Excipient: Used as a solubilizer and bioavailability enhancer in lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS).
• Nutraceutical Formulations: Serves as a carrier for fat-soluble vitamins (A, D, E, K) and ω-3/6 supplements to improve absorption.
• Biochemical Research: Acts as a substrate or intermediate in enzymatic studies, lipid metabolism research, and the synthesis of more complex glycolipids.
• Cosmetic & Personal Care: Incorporated into emollients, moisturizers, and topical formulations for its skin-conditioning and stabilizing properties.
• Specialty Surfactant Synthesis: A key raw material for producing non-ionic surfactants and emulsifiers with specific hydrophilic-lipophilic balance (HLB) values.
• Polymer & Material Science: Used as a monomer or plasticizer in the synthesis of biodegradable polymers and specialty resins.
