Diethylene Glycol (DEG)

Diethylene Glycol (DEG) is an organic compound with the chemical formula C₄H₁₀O₃. It is a colorless, odorless, and slightly sweet-tasting liquid that is hygroscopic and miscible with water, alcohol, and many organic solvents. It is a member of the glycol family and is produced through the hydration of ethylene oxide.

Solvent: DEG is used as a solvent for paints, coatings, inks, and in chemical formulations.
Antifreeze and Coolant: It is used in the production of antifreeze for cooling systems, especially in automobiles and air conditioning units.
Plasticizers: DEG acts as a plasticizer in the manufacture of plastics.
Humectant: It is used in cosmetics, personal care products, and pharmaceuticals to retain moisture.
Hydraulic Fluids: DEG can be found in hydraulic fluids used in heavy machinery and systems.
Production of Polyurethanes: DEG is an intermediate for manufacturing polyurethanes, particularly in flexible foams.
As a Reagent: It is used as a chemical intermediate in producing other chemicals such as esters and ethers.
