Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2. It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations.
Ethylene glycol (EG) fluids are still in use for aircraft deicing in some parts of the world because it has a lower operational use temperature (LOUT) than propylene glycol (PG). However, PG is more common because it is less toxic than ethylene glycol. [6]: 2–29 [2]
^2 Includes mono- and di- ethers of ethylene glycol, diethylene glycol, and triethylene glycol R−(OCH 2 CH 2) n −OR' where; n = 1, 2, or 3 R = alkyl C7 (chain of 7 carbon atoms) or less; or phenyl or alkyl substituted phenyl R' = H or alkyl C7 or less; or OR' consisting of carboxylic acid ester, sulfate, phosphate, nitrate, or sulfonate.

The most common source of ethylene glycol is automotive antifreeze or radiator coolant, where concentrations are high. [9] Other sources of ethylene glycol include windshield deicing agents, brake fluid, motor oil, developing solutions for hobby photographers, wood stains, solvents, and paints. [9]
DeCarlo said nearly all the readings were higher than 11 parts of ethylene oxide per 1 trillion parts of air — a level that translates to a one in 10,000 cancer risk for long-term exposure to ...
The precursor to PEGs is ethylene oxide, which is hazardous. [42] Ethylene glycol and its ethers are nephrotoxic (poisonous to the kidneys) if applied to damaged skin. [43] The United States Food and Drug Administration (FDA or US FDA) regards PEG as biologically inert and safe. [citation needed] A 2015 study appears to challenge the FDA's ...
A former Air Force base responsible for potentially exposing hundreds of thousands to toxic chemicals is now a desolate wasteland that has remained abandoned in California for 32 years.
