Monoethylene Glycol

Monoethylene glycol is a colorless, transparent and slightly viscous liquid. It tastes slightly sweet. It is hygroscopic. It is miscible with water, glycerol, acetone, acetic acid, etc., slightly soluble in ether, and insoluble in benzene, petroleum ether, and oils. It is used in the manufacture of resins, plasticizers, synthetic fibers, cosmetics and explosives, etc.
