Use in Paintballs

Polyethylene Glycol is the main ingredient in paintballs, not Propylene Glycol. http://www.severepaintball.com/pdf/msds.pdf (link to a pdf for the MSDS for a certain brand of paintballs) http://paintball.about.com/b/a/079179.htm (about.com article that mentions polyethylene glycol as the main ingredient)

Recent stories relating to -e-cigarettes

Citation 25 relates to deaths suspected to have been related to vaping THC derivatives - no mention at all of link to Propylene Glycol — Preceding unsigned comment added by 194.168.131.146 (talk) 16:56, 10 October 2019 (UTC)[reply]

as energy source

Can the L-isomer (synonym of S-isomer?) be used as main energy souse in food instead of glucose to produce effect similar to that of keto-diet but without its negative sides? 79.181.84.239 (talk) 14:37, 12 June 2021 (UTC)[reply]

a) this is not a discussion forum, it's about a Wikipedia entry

b) the L-isomer is not a synonym of the S-isomer, they are isomers, not synonyms, but this is completely irrelevant

c) No. While you can get your calories from propylene glycol, foregoing sugar and fats, it is not recommended because in these amounts it would not be healthy any more. And more relevant to your question, it will not produce the same effect as to that of a keto-diet, because propylene glycol is metabolized via puryvate and lactate, which are not so called "ketone bodies". It is even used in cows to intervene when they enter a state of ketosis because it is considered to be unhealthy for them. Wolfgang.brehm (talk) 10:00, 29 December 2022 (UTC)[reply]

Acetaminophen aka Paracetamol in Cows

As a chemist I was surprised to read that cows produce paracetamol in significant quantities. Anything is possible, but better check the sources. The source indeed gives the quote, but cites another source, which does not substantiate this claim at all. The primary source shows that giving propylene glycol to hungry cows reduces their acetate, but nowhere do they mention acetaminophen. Perhaps, and this is just an educated guess, the secondary source meant to write acetoacetate or acetone, not acetaminophen, because these are common ketone bodies. In any way, the extraordinary claim that cows supposedly produce paracetamol would require extraordinary evidence. This is not substantiated by any evidence at all in my assessment. Do you agree to remove this quote and replace it with a more trivial statement as in reducing ketosis measured by acetate in their blood?

-== Please create a non-technical site ==
-Someone needs to create a non-technical version of Wikipedia. This page is useless for non-technical people. Propylene glycol is used in many flavorings (extracts or whatever) yet the "Applications" section in particular is highly technical. It would help to be able to understand why Propylene glycol is used in many flavorings and we need a non-technical site for that. Or maybe people should stop trying to show off how much they know and instead try to help people to understand technical things such as Propylene glycol.
