Products Description of Ethylene glycol CAS 107-21-1

Ethylene glycol is mainly used to prepare antifreeze for automobile cooling systems and to produce polyethylene terephthalate (raw material for polyester fibers and polyester plastics). It can also be used to produce synthetic resins, solvents, lubricants, surfactants, softeners, wetting agents, explosives, etc. Ethylene glycol can often replace glycerol and is used as a hydrating agent and solvent in the leather and pharmaceutical industries, respectively. Ethylene glycol has a strong solubility, but it is easily metabolized and oxidized to produce toxic oxalic acid, so it cannot be widely used as a solvent.
