Diethylene Glycol (DEG), commonly known as ethylene diglycol, is an organic substance. It is a hygroscopic chemical that is toxic, colourless, odourless, and has a somewhat pleasant taste. Ethylene oxide is partially hydrolyzed to create it. DEG is typically employed as a solvent, despite the fact that it may be a contaminant in some consumer goods. As a result, there were many epidemics in the early 20th century. Governments in several nations have imposed strict limitations on its use as a result of this. DEG is used in a variety of industries, including the production of tobacco, paper and pulp, printing inks, and leather.
Additionally, it serves as a raw material for polyester resins, plasticizers, and thermoplastic polyurethanes.When ethylene oxide partially hydrolyzes, Diethylene Glycol (DEG) is produced. It is a sweet-tasting, colourless liquid with little volatility. It is soluble in acetone, water, alcohol, and other organic solvents. DEG is a well-liked solvent for printing, oils, resins, paint pigments, and textile dyes. In addition, it is used as a raw ingredient to make polyester resins, thermoplastic polyurethanes, and plasticizers.
