The markets for EG products are polyester fibres, polyethylene terephthalate (PET) plastics, coolants in automobile antifreeze, and resins. The excellent humectant (hygroscopicity) properties of EG products also make them ideal for use in fibres treatment, paper, adhesives, printing inks, leather and cellophane.  Ethylene glycol is also a commonly used with fog generators or artificial smoke production.
