Ethylene glycol CAS#107-21-1

Basic Information

Ethylene glycol

Ethylene glycol is an industrial glycol used as an antifreeze ingredient and a principal feedstock for polyethylene terephthalate. The resulting polyester materials serve fiber and plastics manufacture. Other applications include synthetic resins, lubricants, surfactants, softeners and wetting-agent formulations. Its solvent compatibility also supports selected chemical-processing and leather-treatment uses, although its toxicity limits suitability as a general-purpose formulation solvent.

product description

Versatile Industrial Applications: Ethylene glycol is widely used in automotive antifreeze, polyester production, synthetic resins, solvents, lubricants, surfactants, and other industrial applications.


Effective Raw Material for Polymers: It serves as a key precursor for polyethylene terephthalate (PET), the primary raw material for polyester fibers and plastics.


Substitute for Glycerol: Ethylene glycol can replace glycerol in various applications, functioning as a hydrating agent in leather processing and as a solvent in pharmaceutical formulations.


High Solubility: The compound exhibits strong solubility, making it compatible with a wide range of formulations and chemical processes.

Product Description of Ethylene Glycol (CAS 107-21-1)

Ethylene glycol is primarily used in the production of antifreeze for automotive cooling systems and as a key raw material for polyethylene terephthalate (PET), which is used in polyester fibers and plastics. It is also employed in the manufacture of synthetic resins, solvents, lubricants, surfactants, softeners, wetting agents, explosives, and other industrial products.

Ethylene glycol can often serve as a substitute for glycerol, functioning as a hydrating agent in leather processing and as a solvent in pharmaceutical applications. The compound exhibits strong solubility; however, it is easily metabolized and oxidized to form toxic oxalic acid, limiting its use as a general solvent.

Product Application of Ethylene Glycol (CAS 107-21-1)

Ethylene glycol is primarily used in the manufacture of synthetic resins, surfactants, and explosives. It is also widely applied as an antifreeze agent.
