Description

1,3-Dilinoleoyl-2-Stearoyl Glycerol is a structured triglyceride (TAG) composed of linoleic and stearic fatty acids in a specific positional arrangement. This precise molecular architecture is critical for applications requiring controlled lipid behavior, such as in specialized nutritional formulations and advanced material science. It is particularly valuable to manufacturers in the nutraceutical, food science, and cosmetic industries seeking to engineer specific physical and metabolic properties into their products.

Application

• Structured Lipid for Clinical Nutrition: Used in medical and infant formula to provide tailored fatty acid delivery and improved absorption profiles.
• Functional Food Ingredient: Incorporated into foods designed for metabolic health, leveraging the properties of its constituent fatty acids.
• Cosmetic & Personal Care Actives: Serves as an emollient and carrier oil in high-end skincare products for its skin-conditioning benefits.
• Pharmaceutical Excipient: Acts as a lipid matrix or solubilizer in lipid-based drug delivery systems (LBDDS) to enhance drug bioavailability.
• Biochemical Research: Utilized as a standard or substrate in lipid metabolism, enzymology, and nutritional studies.
• Specialty Lubricants & Release Agents: Employed in niche industrial applications requiring bio-based and food-grade lubricating properties.

Quality Control

Our 1,3-Dilinoleoyl-2-Stearoyl Glycerol is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure identity, purity, and consistency, with specifications tailored to meet the demands of food, pharmaceutical, and research applications. A comprehensive Certificate of Analysis (COA) detailing assay, fatty acid composition, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen) at 2-8°C. The material is easily oxidized; avoid exposure to heat, air, and pro-oxidants. Allow the container to reach room temperature before opening to prevent moisture condensation.
