Mono ethylene glycol
The most common use of ethylene glycol is as an antifreeze in cooling in cars and air conditioning systems. Mixing ethylene glycol with water provides additional benefits to coolant and antifreeze solutions, such as preventing corrosion and acid degradation, as well as inhibiting the growth of most microbes and fungi. In the plastics industry, ethylene glycol is an important precursor for polyester fibers and resins. Polyethylene terephthalate, which is used in making plastic bottles for soft drinks, is made from ethylene glycol.
