Description

2-Octanoyl-1,3-Distearin is a structured triglyceride, a specific ester of glycerol where the sn-1 and sn-3 positions are esterified with stearic acid and the sn-2 position with octanoic (caprylic) acid. This precise molecular architecture provides unique functional properties, making it a valuable intermediate and functional ingredient. It is particularly relevant for manufacturers in the specialty chemicals, cosmetics, and pharmaceutical industries seeking tailored lipid materials for advanced formulations.

Application

• As a key intermediate in the synthesis of structured lipids and specialty esters for nutritional and pharmaceutical applications.
• As a texturizing and stabilizing agent in high-end cosmetic and personal care formulations, such as creams, lotions, and makeup.
• As a controlled-release matrix or carrier lipid in pharmaceutical drug delivery systems.
• As a model compound for research in lipid metabolism, digestion, and absorption studies.
• As a functional ingredient in specialty lubricants and release agents for industrial applications.
• As a base material for further chemical modification to create novel surfactants or emulsifiers.

Quality Control

Our 2-Octanoyl-1,3-Distearin is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay, fatty acid composition, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen or argon blanket) to maintain stability.
