Triethylene glycol, TEG, or triglycol is a colourless odourless viscous liquid with molecular formula HO((CH₂CH₂)O)₃H. It is used as a plasticizer for vinyl. It is also used in Air-Sanitizer products, like "Oust" or "Clean and Pure." When aerosolized, it acts as a disinfectant. Glycols are also used as liquid desiccants for natural gas and in air conditioning systems. It is an additive for hydraulic fluids and brake fluids.

Triethylene glycol (TEG) is a member of a homologous series of dihydroxy alcohols. It is a colourless, odourless stable liquid with low viscosities and high boiling points. Apart from its use as a raw material in the manufacturing and synthesizing of other products TEG is known for its hygroscopic quality and its ability to dehumify fluids. It is viscous liquid; miscible with water with a boiling point of 198 C and a melting point 13 C. It is also soluble in ethanol, acetone, acetic acid, glycerine, pyridine, aldehydes; slightly soluble in ether and insoluble in oil, fat, hydrocarbons. It is prepared commercially as a co-product of the oxidation of ethylene at high temperature in the presence of silver oxide catalyst, followed by hydration of ethylene oxide to yield mono-, di-, tri-, and tetraethylene glycols.
