Propylene Glycol and Lactic Acid

[dave654678]

i'm new here also..

i'd like to have the information regarding the speed of propylene glycol oxidation in air at temperatures in the range of the an electronic cigarette heats it up to.

i found this paper. http://fire.nist.gov/bfrlpubs/build85/PDF/b85010.pdf
indicating the degredation to acids is so slow, even at 101 degrees C that its neglegible. the units are part per million over lots of hours.
a 510 atty tested heats up to approx 180 F which translates to approx 80 degrees
(http://www.e-cigarette-forum.com/fo...pylene-glycol-vaporization-atomizer-temp.html), bearing in mind the temperature of PG vapourization is about 60+ degrees c


i'd also like to point out, that you will be using mouthwash that contains propylene glycol, as will your tooth paste...

at some point i will find the concentration of lactic acid in the blood, and compare this to the maximum amount of possible conversion of propylene glycol conversion to its respective acids @4mg solution. and then i will compare.
but it took me long enough to find that paper.

having said that, my vanilla has started tasting sour... which indicates acidity.. and some other posts have mentioned this occuring in some flavours

It seems there is a lot of false information being stated as fact. Like:

(jokingly paraphrasing)

"too much exercise causes lactic acid buildup which is what hurts you!"

"You get a massage and it releases lactic acid so you need to use a colonic cleanse!"...

These claims probably come from the same people that update their FB status/mass e-mail people about how mars is going to look as big as the moon, or how 11/11/11 only happens once every thousand years. I'm not even sure how these people have survived this long believing everything their hear without first verifying the information.

Not to be the ******** **** ******** that I am, but c'mon people, stop being so ignorant and learn to look some stuff up before regurgitating the stupidity.

this paper is also highly relevant,

it is not the full paper, but the abstract indicates a relationship between dry mouth and an increase of tooth decay.
as can be seen, there is a very large increase of dental problem when saliva rates drop below a certain value

Elsevier

ofc, this is only one paper
