Description

1,2,3-Propanetriol 1-Palmitate 2-Stearate 3-Myristate is a high-purity, mixed triglyceride ester synthesized from glycerol and specific fatty acids. This compound is valued for its unique lipid profile and functional properties, making it a versatile ingredient for demanding industrial and specialty applications. It is particularly sought after by formulators in the personal care, cosmetics, and pharmaceutical industries seeking stable, non-greasy emollients and texture modifiers.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, and makeup products.
• Pharmaceutical Excipient: Used as a lipid-based carrier or matrix for controlled-release drug delivery systems.
• Food-Grade Lubricants & Release Agents: Serves as a base or component in formulations requiring food contact compliance.
• Specialty Chemical Intermediate: Employed in the synthesis of more complex esters and surfactants.
• Plasticizer & Softener: Imparts flexibility and reduces brittleness in specific polymer and resin applications.
• Research & Development: Used as a standard or model compound in lipid chemistry and material science studies.

Quality Control

Our 1,2,3-Propanetriol 1-Palmitate 2-Stearate 3-Myristate is manufactured 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 are available for every shipment. We can support compliance requirements for cGMP, ISO, and REACH as needed for your application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider an inert atmosphere (nitrogen blanket). Keep away from strong oxidizing agents, heat, and ignition sources.
