Description

1-Stearoyl-3-Linoleoyl-Rac-Glycerol is a structured triacylglycerol (TAG) molecule, a mixed triglyceride composed of stearic and linoleic fatty acids. This specific configuration is valued for its unique physicochemical properties, which make it a versatile intermediate and functional ingredient. It is primarily sought after by manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries for research, formulation, and synthesis applications.

Application

• Pharmaceutical Excipient & Drug Delivery: Used as a lipid matrix component in solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) for controlled release formulations.
• Nutraceutical & Functional Food Ingredient: Serves as a structured lipid in specialized nutritional products and dietary supplements designed to modulate fat absorption and metabolism.
• Biochemical & Metabolic Research: Acts as a standard or substrate in enzymatic studies, particularly for lipases and metabolic pathways involving triglyceride hydrolysis and synthesis.
• Cosmetic & Personal Care Formulations: Employed as an emollient and conditioning agent in high-end skincare products for its skin-compatible lipid profile.
• Chemical Synthesis Intermediate: Provides a defined starting material for the synthesis of more complex lipids, phospholipids, and other ester derivatives.
• Reference Standard: Used as an analytical standard in chromatography (HPLC, GC) for the identification and quantification of triglycerides in complex mixtures.
