Ethylene glycol is a colorless, practically odorless, low-volatility, low-viscosity, hygroscopic liquid. It is completely miscible with water and many organic liquids.
The primary use of ethylene glycol is as the main ingredient in antifreeze for vehicles and coolant in industrial cooling systems. It is also used in the production of polyester resins and can be found in some cosmetics as a humectant and solvent.
