Encyclopedic overview
Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. It is a four-carbon dimer of ethylene glycol. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. DEG is a widely used solvent. It can be a normal ingredient in various consumer products, and it can be a contaminant. DEG has also been misused to sweeten wine and beer, and to viscosify oral and topical pharmaceutical products. Its use has resulted in many epidemics of poisoning since the early 20th century.
