Description

1,3-Dilinoleoyl-2-Oleoylglycerol is a structured triglyceride where the sn-1 and sn-3 positions are esterified with linoleic acid and the sn-2 position with oleic acid. This specific molecular configuration is valued for its unique physical and metabolic properties, making it a sophisticated ingredient for advanced formulations. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and specialty chemical industries for its role in lipid-based delivery systems and structured lipid research.

Application

• Pharmaceutical Excipient: Used as a lipid matrix in the development of solid lipid nanoparticles (SLNs) and self-emulsifying drug delivery systems (SEDDS) to enhance the bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Nutraceutical Ingredient: Incorporated into specialized dietary supplements and medical nutrition products designed for targeted metabolic effects and improved fatty acid absorption.
• Biochemical Research: Serves as a critical standard and substrate in lipidomics research, enzymatic studies (e.g., lipase specificity), and metabolic pathway investigations.
• Cosmetic Formulations: Employed in high-end skincare products as an emollient and carrier for active compounds, leveraging its skin-compatible lipid structure.
• Structured Lipid Synthesis: Acts as a key intermediate or model compound for the chemical or enzymatic synthesis of novel triglycerides with tailored nutritional and functional profiles.

Quality Control

Our 1,3-Dilinoleoyl-2-Oleoylglycerol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatographic purity assessment and identity confirmation, to ensure it meets precise compositional specifications. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. For long-term storage, keep under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation. Allow the container to reach room temperature before opening to prevent moisture condensation.
