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)

Reference List Correction

I was going through the references and I found an error with reference #3. The reference points to the correct page number (26) but the wrong volume of the book series. This should cite Volume 2 "Major Oxygenated, Chlorinated, and Nitrated Derivatives" with an ISBN number of "2-7108-0563-4". I tried to edit the reference section although all that shows up is "reflist". Can someone else make this modification (or point me towards a resource that would rectify my ignorance)?

Duplicate reference

The last paragraph of "Humans" and the last paragraph of "Allergic reaction" refer to the same Swedish study. Footnote 37 is a duplicate of footnote 29. --88.73.3.182 (talk) 15:51, 29 January 2012 (UTC)[reply]

Confusion with Ethylene Glycol

I added the Template:Distinguish for Ethylene Glycol. As many people confuse the two when citing human toxicity. For example Austin News called Electronic cigarette poisonous as "They use the same ingredient as car antifreeze". When in fact car antifreeze uses Ethylene Glycol and ecigarretes use Propylene Glycol. Charles Dayton (Talk) 17:01, 11 March 2012 (UTC)[reply]

Actually car antifreeze could be either which is actually why I am here. I wish to have both the boiling points and freezing points in this article.

(article.http://www.acustrip.com/specs/2-wayafauto.html)

Would this meet wiki standards for authoritative? it does have both freeze and boil for propylene glycol used as a coolant. Propylene glycol seems to be most effective at 60% concentration as opposed to70% for ethylene glycol. propylene glycol also seems to have a slightly narrower range of protective temperatures. I understand that it is not so good to mix them and some cars that require one will over heat with the other, but have no good sources for this.

Use in E-Cigarettes

Propylene Glycol is used as a solvent for Nicotine in almost all E-Cigarettes, although it is often mixed with normal (vegetable based) glycerine in various proportions to reduce its unpleasant taste and also because vegetable based glycerine is considered too viscous to use alone, Propylene Glycol is much less viscous and thins the mixture down to a more manageable viscosity. Since E-Cigarettes are becoming more and more popular especially in the last year, I feel it may be worthwhile adding it as a valid application. 86.149.118.241 (talk) 18:17, 17 January 2013 (UTC)[reply]
