Talk:Propylene glycol
From Wikipedia, the free encyclopedia
One of the primary, if not the biggest use of propylene glycol is a safe alternative to ethylene glycol as an antifreeze. That is not mentioned.
This article appears to repeat itself. The second sections contains sentences also present inthe first. I've not got time to do it now (sorry), if someone reads this and it isn't done yet then go for it. I'm just meaning to draw attention to the problem. If it's been fixed then feel free to remove this message. ~Mullet
The cemical formular does not match the pitcher (Written by User:62.252.64.15)
- It does as far as I can see. Cacycle 21:32, 16 Jun 2005 (UTC)
- The chemical formula matches the picture, but the picture does not match the actual structure. One of the hydroxy groups should be attached to the central carbon atom, instead of a terminal one: CH3-CHOH-CH2OH -- Cvitols 6 July 2005 20:26 (UTC)
- Oops. I have corrected the image. Cacycle 6 July 2005 22:49 (UTC)

[edit] Merged
Merged from dup article Propylenglycol. Vsmith 14:21, 6 December 2005 (UTC)
[edit] needs infobox
This substance needs a standard chemical infobox, like other chemical compunds... for example Ethylene glycol. Jamie 01:38, 10 December 2005 (UTC)
[edit] antibacterial?
the deodorant page links to here claiming that propylene glycol is an antibacterial. is this so? source info is pretty weak, http://www.chemicalland21.com/petrochemical/PROPYLENE%20GLYCOL.htm Dreamer.redeemer 07:02, 21 January 2006 (UTC)
[edit] use as a laxitive?
A friend of mine said his mother was prescribed PG for relief of constipation at a hospital and that it worked very well. I haven't researched the net yet for this - any comments?
[edit] IUPAC name
This article says the IUPAC name is 1,2-propanediol. Should it be propane-1,2-diol instead? --Deryck C. 09:22, 24 October 2006 (UTC)
[edit] 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)
[edit] The tasteless flavoring agent?
I want to know how it's used "as a flavoring agent in Angostura and Orange bitters" when the description also says it's "tasteless". Something doesn't match up there. -- JdwNYC 21:33, 16 December 2006 (UTC)
- You're right. Using it as a flavoring agent doesn't make any sense. I did some reading, PG is used as an emulsifying agent in flavors and citrus concentrations. Because the citrus flavor is an oil, it won't mix evenly with water based solutions unless an emulsifier is added. Nice catch. Oasisbob 23:32, 16 December 2006 (UTC)
- ps. This will be a fun one to google in a few months and see how many sources still cite PG "as a flavoring agent in Angostura and Orange Bitters". Oasisbob 23:34, 16 December 2006 (UTC)
