Small amounts of ethylene glycol may be contained in holiday ornaments such as snow globes. [9] The most significant source of ethylene glycol is from aircraft de-icing and anti-icing operations, where it is released onto land and eventually to waterways near airports experiencing cold winter climates.

The US Environmental Protection Agency (USEPA) estimated in 2016 [139] that for low doses, the inhalation of ethylene oxide for a lifetime could increase an individual's lifetime cancer risk by as much as 3.0 × 10 −3 per μg/m 3 (without considering that early-life exposures are likely more potent). The USEPA estimated the slope of the dose ...
That can cause dangerous side effects in the long term, which is why doctors rarely prescribe oral corticosteroids for long-term asthma treatment. Another class of oral meds is called leukotriene ...
Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide. Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation. C 2 H 4 O + H 2 O → HO−CH 2 CH 2 −OH. This reaction can be catalyzed by either acids or bases, or can occur at neutral pH under elevated temperatures. The ...
Dimethoxyethane, also known as glyme, monoglyme, dimethyl glycol, ethylene glycol dimethyl ether, dimethyl cellosolve, and DME, is a colorless, aprotic, and liquid ether that is used as a solvent, especially in batteries. [2] Dimethoxyethane is miscible with water.
2-Hexoxyethanol was also known to cause kidney injury and depression. It is also a severe respiratory tract irritant. It may also have blood effects. [2] It may enter the body through ingestion, aerosol inhalation, and through the skin. [3] It may form explosive peroxides. It can react violently with strong oxidants. [3]
[75]: 162 As of 2014 the long-term effects of inhaled propylene glycol [202] [174] and glycerin were unknown. [197] Exposure to propylene glycol may cause eye and respiratory tract irritation. [ 14 ] Heated and aerosolized propylene glycol can turn into propylene oxide , which the International Agency for Research on Cancer (IARC) labels a ...
Polymerization of ethylene oxide is an exothermic process. Overheating or contaminating ethylene oxide with catalysts, such as alkalis or metal oxides, can lead to runaway polymerization, which can end in an explosion after a few hours. Polyethylene oxide, or high-molecular-weight polyethylene glycol, is synthesized by suspension polymerization.
