Description

1,2-Dilinoleoyl-3-Stearoyl-Rac-Glycerol is a structured triglyceride composed of linoleic and stearic acid residues. This specific fatty acid configuration is valued for its unique physical and chemical properties, making it a versatile intermediate and functional ingredient. It is primarily sought by manufacturers in the cosmetics, personal care, and specialty chemical industries for formulating advanced lipid-based products.

Application

• Cosmetic and Personal Care Formulations: Acts as a high-performance emollient, skin-conditioning agent, and carrier oil in creams, lotions, and serums.
• Pharmaceutical Excipient: Used as a lipid component in drug delivery systems, including lipid nanoparticles (LNPs) and self-emulsifying drug delivery systems (SEDDS).
• Biochemical Research: Serves as a standard or substrate in lipid metabolism studies and enzymatic assays.
• Specialty Lubricants and Release Agents: Employed in niche industrial applications requiring bio-based or food-contact compliant lubricating properties.
• Structured Lipid Synthesis: A key intermediate for the production of other tailored triglycerides with specific nutritional or functional profiles.

Quality Control

Our 1,2-Dilinoleoyl-3-Stearoyl-Rac-Glycerol is produced and controlled under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, fatty acid composition, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) to minimize oxidation. Keep the container tightly sealed in a cool, dry, and well-ventilated area away from incompatible materials.
