Talk:Ethylene glycol

bio ethylene glycol
www.plasticsnews.com/article/20130607/NEWS/130609933/cokes-plantbottle-use-swells-globally it seems that their is a bio source for this, perhaps something sould be added about how its obtained. — Preceding unsigned comment added by 98.116.80.153 (talk) 21:28, 15 November 2013 (UTC)

teratogen
My edit naming and sourcing ethylene glycol as teratogen was reverted by with the reason "we [sic!]'d need a better resource for this." This appears unreasonable and heavy-handed.

First, the source is the Canadian government, a tertiary source, no little peer-reviewed article. Second, the prior, unsourced claim of teratogenicity in birds was in the article with a citation needed sign. If Smokefoot really had an issue with this claim, he could have removed that. Thus t fact that a properly sourced claim is reverted, smells of WP:POV. Third, if Smokefoot was interested in the issue he could have added a source he likes, there are numerous to choose from.

IMHO a general problem with the chemistry sites is, that they have no toxicology section in their template and most chemists appear uncomfortable with the material. --Wuerzele (talk) 18:11, 27 August 2014 (UTC)

which one is it?
"first prepared ethylene glycol in 1859, he actually first prepared it in 1856". I think this needs fixed, does it not?--Craxd (talk) 13:23, 24 November 2014 (UTC)
 * The cited reference says 1856, so I rephrased the sentence to agree with that. -- Ed (Edgar181) 14:53, 24 November 2014 (UTC)

Polyethylengylcol - PEG - Macrogol
Hi,

maybe it should be mentioned that in some Areas (Europe) it is the No. 1 for obstipation (I hope it is in English correct too), if it is not just a easy one, but for me for example, high methadone dosage... and when a clear "intestinal"(?)-tract is needed a high dose and than Macrogol 4000 or higher is used, against long-term obstipation, the Macrogol 3350 (mmol/L I think it is, since it comes with a mmol/L like 44, but is not really solutable in water than), however the heavy packs contain like Macrogol 4000 from 50 to 100g to REALLY make everything clean. The other bags usually have Macrogol 3350 with 13.125g combined with 3 substances to keep body in balance (Caliumchlorid, Natriumhydrogencarbonat, Natriumchlorid).

It is the best long-term medication compared to things like Lactulose (which sucks...) or older salts. I think the production of Polyethylenglycol (PEG/Macrogol) goes far beyond 1 million tons, I can't believe that it is only used in German speaking countries?! Movicol is the "trademark" best known there, Generica of course exist... It is over the counter but for people getting Opioid medication the medical insurance I have (the most common) pays only 2 medications, this being one of them.

So I guess they get heavy discount than... I first did not believe it could help on dosages equivalent to far over 1000 mg or Morphine, but if you drink enough it works... Poly... always "plastic" for me, and somehow I think it is? But wayne, wouldn't it be safe it would not be registered and so widely used in Germany. Even kids get it ("Movicol Junior") with lower dosage of course than. I am taking Methadone so long now, I think next weekend with Take-Home I will try the dose they use for colonoscopy to get everything clear since I once saw a ugly picture. However, it is made from crude oil or?!

 * Polyethylene glycol has its own page, it is a common laxative in the US and many other countries. In the US, it is often referred to by the trade name MiraLax. It is over-the-counter in the US. I would estimate that polyethylene glycol and cellulose are the two laxatives most often recommended by doctors in the US for long-term use. Polyethylene glycol is the most common laxative for colonoscopy preparation in the US. Fluoborate (talk) 18:54, 17 June 2017 (UTC)

Pure propylene glycol is not bitter
Several months ago, I removed a claim that propylene glycol tastes bitter, whereas ethylene glycol tastes sweet. My edit was reverted because the source cited actually does claim that propylene glycol tastes bitter. This is a reasonable misunderstanding, a Google search indicates that commercial-grade propylene glycol often tastes bitter or acrid, but the taste is variable because it depends on impurities. Propylene glycol is also a common food additive, it serves a role similar to glycerol as a hygroscopic liquid and solvent. I added two citations to the Merck Index, which describes the flavor of both ethylene glycol and propylene glycol (and thousands of other chemicals). In my opinion, the Merck Index is a more reliable source when the fact in question is the taste of a common chemical. A scientific study where volunteers rate the taste would be even higher-quality evidence, but I doubt such a study exists. Here is some original research that I did not include in my footnote: I have tasted pure propylene glycol, and the taste is very mild and a bit sweet. Propylene glycol tastes similar to glycerol, but far less sweet. They both are a tiny bit bitter, similar to aspartame or many other non-sugar sweeteners. The bitterness is so mild that a small child would definitely drink a large volume of propylene glycol or glycerol, if given the chance. In contrast, isopropanol (the analogous compound with only one hydroxyl group) tastes very foul, similar to ethanol, and a child would not want to drink it.

Toxicity?
Moderately toxic? No. Very toxic.Longinus876 (talk) 14:42, 16 February 2018 (UTC)
 * Compared to many other poisonous things it is only moderate. But because it is sweet, it can be consumed with awareness of the danger. With some substances you would be killed by 0.05 grams, but not this. Graeme Bartlett (talk) 11:19, 17 February 2018 (UTC)

Incorrect formula for ethene
Under "Production" -> "Industrial routes" it states the formula for ethene is C2H4O whereas it should be without the final oxygen atom. Or am I missing something..? — Preceding unsigned comment added by Wikikrema33 (talk • contribs) 09:08, 21 January 2021 (UTC)

Replacing a citation to berrymanchemical.com with one to atamanchemicals.com
The article cites a dead link from berrymanchemical.com as supporting: It also can be used as a formaldehyde substitute when preserving biological specimens. I have looked at web archive, and this produces archived pages to the berrymanchemical.com site that say "page not found". I searched for "Monoethylene Glycol" on the berrymanchemical.com site and found: [https://www.berrymanchemical.com/products/specialty-and-commodity-chemicals/ Specialty and Commodity Chemicals. Berryman Chemical provides the specialty and commodity chemicals, packaging, shipping and support you need.] This says: Monoethylene glycol (MEG) is a basic building block in applications that require chemical intermediates for resins, solvent couplers, freezing point depression solvents, and humectants. MEG is also used in chemical intermediates such as antifreeze, automotive coolants, resins, water-based adhesives, electrolytic capacitors, latex paints, asphalt emulsions, textile fibers, paper, and leather.

The citation and the text was added by Editor755 on 5 August 2020, with a citation template that gave the access date as 5 August 2020. The text at that date included in vaccine manufacture or.

atamanchemicals.com Monoethylene Glycol is a citation that also supports the current text. So I have replaced the berrymanchemical.com citation with one to atamanchemicals.com. -- Toddy1 (talk) 13:09, 21 August 2023 (UTC)

Solubility
the solubility says it is "partially miscible" in some solvent. That's not a thing. A liquid is either miscible with another liquid or it isn't. Miscible means that they can be mixed in any proportion without phase separation. Science Is My Life (talk) 23:40, 18 April 2024 (UTC)

why would the substance be green? 🤔
