Description
A clear, colorless, syrupy liquid that is the simplest glycol in its homologous series. While ethylene glycol has a sweet taste, it is extremely poisonous and should not be ingested. Ethylene glycol lowers the freezing point of water and is widely used in antifreeze formulations. Additionally, ethylene glycol is Hygroscopic and is used as a combined Humectant, Solvent, and Plasticizer in inks, paints, plastics, textiles, and leathers. It is also used as a component to synthesize explosives, alkyd resins, plasticizers, synthetic waxes, and synthetic fibers (Dacron®, Terylene).
