DEG- Diethylene glycol

DEG- Diethylene glycol

Chemical Name: Diethylene glycol

Trade Name: DEG


Diethylene glycol (DEG) is an odorless, colorless, clear and viscose liquid with a sweet taste, which is produced from the reaction between water and ethylene oxide. In fact, it is the co-product of ethylene glycol alongside with triethylene glycol (TEG). It is miscible with water, alcohols, acetone, ether and has the chemical formula of C4H10O3.

In terms of chemicals properties, diethylene glycol is similar to MEG (mono ethylene glycol), but it has a higher specific gravity, viscosity and boiling point.

General Applications:

Diethylene glycol is used in the manufacture of unsaturated polyester resins, plasticizers and polyurethanes. It is also used as textile lubricant, solvent in textile dyeing and printing, humectant, selective solvent for aromatics in petroleum refining, plasticizer for paper, cork and synthetic sponges, raw material for the production of esters used as emulsifiers and demulsifiers, constituent of hydraulic fluids and solvent in printing inks.
