Description

1,2,3-Propanetriol=1-Palmitate 2-Myristate 3-Stearate is a high-purity, mixed triglyceride ester of glycerol with palmitic, myristic, and stearic acids, offering a unique and controlled fatty acid profile. This compound is valued for its ability to provide specific melting characteristics, texture, and stability in formulations, making it a critical functional ingredient. It is primarily sought by manufacturers in the cosmetics, personal care, and pharmaceutical industries for use in emollients, stabilizers, and controlled-release matrices.

Application

• Cosmetic & Personal Care Emollient: Used in creams, lotions, and lipsticks to provide a smooth, non-greasy feel and improve skin texture.
• Pharmaceutical Excipient: Serves as a base or lubricant in tablet formulations and as a matrix for controlled drug delivery systems.
• Food-Grade Additive (where compliant): Functions as an emulsifier, texturizer, or coating agent in specialized food products.
• Industrial Lubricant & Plasticizer: Employed in the production of specialty lubricants, plastic films, and polymer processing aids.
• Candle & Wax Manufacturing: Modifies the melting point and burn characteristics of wax blends for enhanced performance.
• Research & Development: Used as a standard or reagent in biochemical and chemical synthesis research.

Quality Control

Our 1,2,3-Propanetriol=1-Palmitate 2-Myristate 3-Stearate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) upon request, detailing key parameters such as assay, fatty acid composition, and impurity profiles. Specifications can be tailored to meet USP/NF, FCC, or Kosher standards as required.

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 material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve stability and prevent rancidity. Keep away from strong oxidizing agents.
