Diethylene glycol

Diethylene glycol (CAS 111-46-6 ), commonly sourced as DEG, is a hygroscopic diol used across industrial manufacturing as a solvent, plasticizer, and chemical intermediate.

Its moderate volatility and water miscibility make it a practical carrier and processing aid in formulations where slower evaporation is commercially advantageous for the manufacturer.

In polyester resin and polyurethane production, DEG functions as a monomer or co-monomer, directly influencing the flexibility and softness of the finished polymer during the synthesis process.

Natural gas processors use it as a dehydration agent to remove water vapor from gas streams before pipeline transmission. Textile and leather finishing operations apply DEG as a softening agent.

These applications improve the hand-feel and workability of treated materials. Printing ink and packaging adhesive formulators incorporate it as a solvent and humectant to control viscosity.

This prevents premature drying during processing. Diethylene glycol is supplied as a clear, colorless liquid in bulk quantities, including ISO tank, flexi-tank, and drum packaging options.

Technical grade is the standard commercial specification, meeting purity requirements suitable for industrial polymer, solvent, and gas processing applications across various global markets.

High-purity grades are available for specialty applications where tighter quality parameters are required by the end formulation to ensure consistent performance and chemical stability.
