Description and Uses

Diethylene glycol (DEG) is a commonly used solvent and ingredient in numerous commercial products. It is used as a dehydrating agent for natural gas processing; as a lubricating and finishing agent for textiles; a constituent in brake fluids, lubricants, antifreeze formulations, wallpaper strippers and in artificial fog solutions; a solvent for printing inks and textile dyes; and is used as an intermediate in the production of some resins, triethylene glycol, surfactants, and diethylene glycol esters and ethers.
