Description

1,2-Distearoyl-Rac-Glycerol is a high-purity synthetic glyceride, specifically a diacylglycerol (DAG) with two stearic acid chains. This compound is a critical intermediate and functional excipient valued for its role in lipid metabolism research and its excellent emulsifying and stabilizing properties. It is essential for manufacturers and researchers in the pharmaceutical, nutraceutical, and advanced cosmetic industries seeking reliable, high-quality lipid components for formulation development.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of more complex phospholipids and prodrugs.
• Biochemical Research: Used as a standard or substrate in studies of lipid digestion, absorption, and metabolism.
• Nutraceutical Formulations: Employed as a component in lipid-based delivery systems for fat-soluble vitamins and bioactive compounds.
• Cosmetic & Personal Care: Acts as a non-ionic emulsifier and emollient in high-end creams, lotions, and ointments.
• Food Science: Utilized in research on fat crystallization and as a model system for studying food emulsion stability.
• Liposome & Nanoparticle Preparation: Serves as a structural lipid in the development of drug delivery vesicles.
