Scroll down to the bottom of the first page where the article by Kathleen Kreiss starts.Sorry, SHS has been so disproven by so many other studies that I don't care to read another one, esp. from a colleague of Stanton Glantz at the UCSF.
No, not really. Much more to do with the process of formulating the flavors. Very interesting story. But it's for another day (sorry, not Thursday).Does it have anything to do with the 'right people' being formerly on the other side of the fence?
The short answer is yes it may, the diacetyl will/may form from alcohols being present in some flavors and when mixed with another water soluble or alcohol flavor it may start the chain reaction.. The link I posted to wiki's defining of diacetyl explains this alcohol chaining of diacetyl production. The long answer has to be explained by a chemist.. But yes it can..
Here's the chaining of how it occurs.
"A distinctive feature of diacetyl (and other 1,2-diketones) is the long C-C bond linking the carbonyl centers. This bond distance is about 1.54 Å, compared to 1.45 Å for the corresponding C-C bond in 1,3-butadiene. The elongation is attributed to repulsion between the polarized carbonyl carbon centers.[2] "
Bond together those chains and it starts forming, steep it long and it grows..
Ya its a tragedy to all of us whom enjoy complex ejuices but with proper chemistry rules in combining flavors we can eliminate it..
It will take proper professional research as with epoxy you have two separate chemicals mix them together and they make a whole different chain of chemical composition. Ya we definitely need some knowledge or just stick with basic juices known not to contain diacetyl..
That would indeed be an interesting experiment.Has anyone ever shown diketone test results for fresh mixed liquid, then again for the very same liquid after several months steeping?

Look - as pointed out by niknik - I addressed the wrong piece on the link from SJ. I saw Mark D. Eisner's name at the top - I knew about his junk science on second-hand smoke before I started vaping 6 years ago, and dismissed it out of hand without even scrolling down. And if there was a junk science piece as the first article, that doesn't say much for the second.
So here we have a juice company adamantly stating that there juice is clean but they have never tested it. ?????
It all makes me want to grab a Marlboro

I'm not sure it would make any difference. Diketones do not chemically change over time, nor do they break down or increase by any significant amount. Other flavors may be altered by the aging process, but the volume of diketones should remain pretty constant.
Part of the reason they are used as flavoring in microwave popcorn is because they remain at a consistent level of saturation and flavoring over extended periods of time on shelves. You wouldn't want your 4 month old bag of popcorn to taste any different from your fresh bag of popcorn.

Surely any article/study could be discussed on it's own merit though. I don't think it's tainted solely by it's proximity to another unrelated article.
Wasn't meaning to offend.
My point was any studies on tobacco are irrelevant...
I am not sure which post you are referring to, you posted excerpts and not the complete post, but yes it's likely those quotes came from one of my posts. My views on the topic are still evolving, but to me the real issue is vendor transparency. I don't want to persuade or dissuade anyone as to the potential risk of these compounds. I have a feeling i am more concerned than you, but i respect any informed decision others make re what they inhale."doesn't say much" doesn't totally dismiss - your right, but it can sometimes be a clue as to what follows, esp. it is combined in that fashion. And I had abandoned the thread earlier - said what I wanted to say - and took Mark Twain's advice with regards to some comments.
Ran by this looking up something else - your post from earlier - If you still hold that view, we agree on that aspect of the subject.
"Why can't they say that yes there is diacetyl in our products, but there is no "clear and present danger". I will make my own decision as a consumer."
