Diethylene glycol (DEG) is a versatile glycol ether widely used as a solvent, humectant, and chemical intermediate. It is applied in the manufacture of resins, plasticizers, polyurethane products, brake fluids, printing inks, dyes, coatings, adhesives, and textile processing agents. It is also used as a solvent for water-insoluble substances and as a raw material for glycol ether derivatives.
