Triethylene Glycol[edit]

Should there be a Triethylene Glycol page? To record its CAS and SMILES info more appropriately?

I think thats warranted, its an important chemical in the gas treatment HarmoniK 01:02, 29 August 2007 (UTC)[reply]

Article about usage/contamination in toothpaste[edit]

Found this article originally from AP. Is this the same DEG? --Silvaran 00:36, 2 June 2007 (UTC)[reply]

Yes. There ain't no other! --King Hildebrand 20:27, 20 June 2007 (UTC)[reply]

Neutrality and Toxicity[edit]

Diethylene glycol is very toxic however, this page appears to have been created for the specific purpose of warning about the toxicity. Information about the toxicity of a chemical should definitely be included in articles as should poison warnings. This article should be reworded so that references to toxicity are concentrated under one heading. To spread references about toxicity throughout the article make it sound more like a consumer warning than unbiased information. I would suggest the skull and cross bones poison symbol be added to the heading of any chemical that is poisonous and that the FDA has required be labeled as a poison. This could satisfy the need for a warning about toxicity.

I tried to correct the issue with POV. A problem with WE-chem articles is that toxicity trivia provides material for those with an urge to edit but who know no chemistry. Regarding your recommendation about "skull and cross bones": virtually every chemical can be considered poisonous (and our physical world is composed exclusively of chemicals). Not sure what to think about the U.S.'s FDA: NPOV? Authoritative? (Certainly it is large and powerful in the US). --Smokefoot 21:59, 3 June 2007 (UTC)[reply]
DEG has an estimated LD50 of around 3000mg/kg which is the same as table salt's. (arguably, the estimated human LD50 is ~12,000mg/kg, 4 times higher for salt). IOW, it is simply NOT TRUE that DEG is "very toxic". But its use as a solvent or adulterant means that the dose can be high enough to be toxic.40.142.185.108 (talk) 15:29, 18 July 2019 (UTC)[reply]

TEG uses[edit]

Under TEG there is a sentence, "Glycols are also used as liquid desiccants for natural gas and in air conditioning systems." The sentence as phrased appears to refer to glycols generally, not just TEG. Since I can't find in a quick check what desiccants are used for natural gas, I haven't adjusted the article text, but it doesn't read right the way it is. --King Hildebrand 20:31, 20 June 2007 (UTC)[reply]

Personal care uses[edit]

The phrase DEG is often substituted by the much less toxic diethylene glycol ethers is ungrammatical, and as a result ambiguous.

If it means "DEG is used instead of DEG ethers" (because it's cheaper), it should be written "DEG is subsitituted for...." If it means "DEG ethers are used instead of DEG" (because they're less toxic), it should be written "DEG is replaced by...." ABehrens 16:46, 15 July 2007 (UTC)[reply]

Good point. Thanks. Been there; done that! --King Hildebrand 14:21, 29 August 2007 (UTC)[reply]

More Explanation Please[edit]

While I pretty much understand the article inasmuch as it describes DEG as a substance that causes water to bind to it, a desiccant, it is not clear at all to me why it is used in toothpaste or cough syrup. Could we have a sentence such as: "for example, a without such a substance in toothpaste, the toothpaste would absorb water and become [overly mushy?] and in cough syrup, the cough syrup would absorb water and become [too thin and lose its viscosity?]

Contradictory information[edit]

"Like ethylene glycol, a solution of diethylene glycol and water is used as a coolant. It both lowers the freezing point of the solution and elevates its boiling point making it more suitable for hot climates."

Diethylene glycol does decrease the freezing temperature, but generally is used for its other properties. Freezing point being around -10 C it's not effective as a practical antifreeze. The information above is not contradictory as there is a big difference between ethylene glycol and diethylene glycol. Perhaps the article could be reworded to specifically address this common misconception as I recall there being media hysteria about this in the past.Blue Leopard (talk) 14:27, 18 November 2008 (UTC)[reply]

I'll get into it in the next 24h. Perhaps I need to start hunting thru refs before I copyedit in future... (!) Freestyle-69 (talk) 21:07, 18 November 2008 (UTC)[reply]

Mass poisonings section[edit]

The article is becoming swamped with this section, as would the article on water if we listed all the people that died via ingestion of that. Unless there are any qualified objections I will be reducing/compacting this section. Freestyle-69 (talk) 21:42, 26 November 2008 (UTC)[reply]

The epidemiology section seems too large and unbalanced - Can we move it to a separate Mass poisonings with diethylene glycol or similar ? Rod57 (talk) 13:57, 29 July 2010 (UTC)[reply]

Synthesis[edit]

It would be nice if the article included a section on the synthesis process(es) used to make diethylene glycol. —Preceding unsigned comment added by Joelthelion (talk • contribs) 12:17, 11 February 2009 (UTC)[reply]

Contradictory Statements[edit]

Under Toxicology: "DEG is not allowed in food and drugs" vs. Fed Regulations allow no more than 0.2% as part of polyethylene glycol (which is allowed). My reading of this is that 21CFR172.820 allows DEG as a food additive (as part of polyethylene glycol). Is this not right? The statement that DEG is not allowed in food and drugs appears to be false.Chemqueen (talk) 21:22, 28 December 2009 (UTC)[reply]

Diethylene glycol in antifreeze[edit]

Most commercial Ethylene glycol antifreeze in the US contains a few percent Diethylene glycol. Why? Because it is a common contaminant of the production process, that would be trouble or expense to remove? Does it add desirable properties?-96.237.78.13 (talk) 15:46, 22 August 2010 (UTC)[reply]

Improper use of the noun 'epidemic'[edit]

"...this has resulted in numerous epidemics..." In this use, 'epidemic' is a noun which means 1. an outbreak of disease that spreads quickly and affects many individuals at the same time or 2. an outbreak or product of sudden rapid spread, growth, or development. Mass ingestion of a poison is not an epidemic, is it? Leveretth (talk) 05:34, 19 July 2017 (UTC)[reply]
