Ethylene glycol is a clear, colorless syrupy liquid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams.

Separated from strong oxidants and strong bases. Dry. Ventilation along the floor.
Polyethylene glycols are chemically stable in air and in solution, although grades with a mol wt < 2000 are hygroscopic. Polyethylene glycols do not support microbial growth, and they do not become rancid. Polyethylene glycols and aqueous polyethylene glycol solutions can be sterilized by autoclaving, filtration, or gamma irradiation Ideally, sterilization should be carried out in an inert atmosphere.

Ethylene glycol Use and Manufacturing
Mainly used in the production of polyester resins, alkyd resins, plasticizers, antifreezes, and also used in cosmetics and explosives; used as analytical reagents, chromatographic analysis reagents and capacitor media; ethylene glycol is the fungicide tebuconazole and moxa The intermediate of the spirit. Gas chromatographic stationary liquid (maximum use temperature 50℃, solvent is chloroform), separation and analysis of low-boiling oxygen-containing compounds, amine compounds, nitrogen or oxygen heterocyclic compounds. Determination of calcium oxide in cement, solvents, antifreeze, manufacture of polyester resins, plasticizers, cosmetics, explosives, cold-resistant lubricants, surfactants, varnishes, dyes, inks, etc., organic synthesis.
