Diethylene Glycol

Diethylene Glycol (DEG) is a versatile glycol compound widely used in industrial, consumer, and specialty applications for its excellent solvency, hygroscopicity, and chemical stability. It functions as both a solvent and humectant, making it valuable in formulations that require moisture retention and compatibility with a wide range of organic and inorganic compounds. DEG is also recognized for its role in heat transfer systems and as an intermediate in polymer and resin chemistry.

In industrial applications, diethylene glycol is used in the production of polyester resins, plasticizers, and polyurethanes, where it improves flexibility and durability. It is also a key component in antifreeze and coolant formulations due to its low volatility and thermal stability. In consumer and specialty products, DEG finds use in coatings, cosmetics, and pharmaceuticals, serving as a carrier, stabilizer, and processing aid. With its balance of performance, cost-effectiveness, and multifunctional properties, diethylene glycol remains an important raw material across industries ranging from automotive and construction to healthcare and specialty chemical manufacturing.
