Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Mixed Hexanoate And Octanoate is a specialized polyethylene glycol (PEG) derivative, specifically a mixed ester of caproic (hexanoic) and caprylic (octanoic) acids. This chemical modification imparts unique amphiphilic properties, making it a highly effective non-ionic surfactant and solubilizer. It is essential for formulators in the pharmaceutical, personal care, and specialty chemical industries who require reliable, high-purity excipients to enhance product stability and performance. The compound is supplied under strict quality control to ensure batch-to-batch consistency for critical applications.

Application

• Pharmaceutical Excipient: Used as a solubilizer and emulsifier in oral, topical, and parenteral drug formulations to improve the bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Personal Care & Cosmetics: Serves as a key ingredient in creams, lotions, and ointments for its emulsifying, skin-conditioning, and stabilizing properties.
• Industrial Surfactant: Acts as a wetting agent, dispersant, and emulsifier in specialty chemical formulations, agrochemicals, and textile processing.
• Food-Grade Additive (where certified): Potential use as an emulsifier in food products, subject to compliance with relevant purity and safety standards like FCC.
• Polymer Plasticizer: Functions as a processing aid and plasticizer in select polymer systems to modify flexibility and processing characteristics.
• Lubricant & Release Agent: Employed in industrial lubricants and as a mold release agent due to its low surface tension and stability.

Quality Control

Our Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Mixed Hexanoate And Octanoate is manufactured under a cGMP-compliant quality management system. Each batch undergoes rigorous analytical testing to ensure it meets stringent specifications for identity, purity, and performance. We provide full traceability and Certificates of Analysis (COA) are available upon request. The product can be tailored to meet various pharmacopeial standards (e.g., USP-NF, EP, JP) or industrial grade requirements.

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 or after opening, consider storing under an inert atmosphere (e.g., nitrogen) to maintain product integrity. Keep away from strong oxidizing agents.
