Description

1,2,3-Propanetriyl=2-Laurate 1,3-Distearate is a high-purity mixed triglyceride, specifically a structured lipid where lauric acid is esterified at the sn-2 position and stearic acid at the sn-1 and sn-3 positions of the glycerol backbone. This specific molecular configuration provides unique physical properties and functional performance, making it a valuable intermediate and functional ingredient. It is primarily sought after by manufacturers in the specialty chemicals, cosmetics, and advanced lubricants sectors for its tailored melting profile and stability.

Application

• Cosmetics & Personal Care: Acts as a high-performance emollient, viscosity modifier, and skin-conditioning agent in creams, lotions, and lipsticks.
• Pharmaceutical Excipients: Used as a matrix former or lipid carrier in controlled-release drug delivery systems and topical formulations.
• Specialty Lubricants & Release Agents: Serves as a biodegradable and stable base or additive in food-grade and industrial release agents and lubricants.
• Food Science Research: Employed as a structured lipid model in nutritional studies and for developing functional food ingredients with specific digestibility.
• Chemical Synthesis: Functions as a key intermediate for the synthesis of more complex lipids, surfactants, and polymer precursors.
• Plasticizers & Stabilizers: Can be utilized as a secondary plasticizer or stabilizer in specific polymer formulations to enhance flexibility and processing.

Quality Control

Our 1,2,3-Propanetriyl=2-Laurate 1,3-Distearate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing including chromatography (HPLC, GC) and spectroscopic methods to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting key parameters such as assay, fatty acid composition, and impurity profiles. Specifications can be aligned with cGMP and ISO guidelines for relevant applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is easily oxidized; for long-term storage, consider filling the headspace with an inert gas (e.g., nitrogen or argon). Keep away from strong oxidizing agents, heat, and ignition sources.
