Diethylene Glycol

The characteristics of MEGlobal’s diethylene glycol (DEG) products supplement our  monoethyleneglycol(MEG) portfolio, augmenting our capabilities to include applications that require hygroscopicity, lubricants and low volatility.

Products that capitalize on these and other DEG properties include:

  • Plasticizers
  • Glass- and cement-grinding aids
  • Furniture and shoe polishes
  • Printing ink
  • Drywall joint compound
  • Thermoplastic polyurethanes
  • Emulsifiers

Diethylene Glycol is a colorless, low-volatility, low viscosity, hygroscopic liquid. Under normal conditions, diethylene glycol has no detectable odor; however, under high vapor concentrations, a slightly sweet odor may be detected.

It is completely miscible with water and many organic liquids.

Because of its higher molecular weight, diethylene glycol is considerably less volatile than ethylene glycol and differs sufficiently in that it has specialized uses. The reactivity and solubility of diethylene glycol provide the basis for many applications.


The hydroxyl groups on glycols undergo alcohol chemistry, providing opportunities for production of a wide variety of derivatives. Hydroxyls can be converted to aldehydes, alkyl halides, amines, azides, carboxylic acids, ethers, mercaptans, nitrate esters, nitriles, nitrite esters, organic esters, peroxides, phosphate esters and sulfate esters.
