Description

Decaethylene Glycol is a high-purity, linear polyethylene glycol (PEG) derivative characterized by its ten repeating ethylene oxide units. This compound serves as a versatile hydrophilic building block and intermediate, valued for its excellent solubility, low volatility, and non-ionic surfactant properties. It is essential for formulators and manufacturers in the pharmaceutical, personal care, and specialty chemical industries seeking reliable performance in synthesis and product development.

Application

• As a key intermediate in the synthesis of specialized surfactants and emulsifiers.
• As a hydrophilic spacer or linker in the production of pharmaceutical conjugates and drug delivery systems.
• In the formulation of high-performance lubricants, plasticizers, and hydraulic fluids.
• As a humectant and solvent in personal care products, including creams, lotions, and cosmetics.
• In chemical research and development as a standard or reagent for polymerization studies.
• As a component in specialty adhesives, inks, and coatings where moisture retention is beneficial.

Quality Control

Our Decaethylene Glycol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your procurement standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality.
