@Sprkslfly @fidalgo_vapes - That could also explain why MF is so expensive. Not only their extraction process but also because they are using PDO; which is not cheap at all and very hard to get.
That’s POINT 4 and POINT 6 percent for everyone.
I strongly (and I can’t emphasize that enough) doubt it.
Why? I’ve never experienced fading issues with MF. In fact, just the opposite.
MF frequently gets stronger (in a mix) as time passes.
I understand there is a high interest in PG, but there is a whole lot of “blah, blah, blah”, between post 46 and 100.
Doesn’t seem like it, this is made both from petroleum and corn syrup… although Wikipedia is known to be wrong from time to time.
Production[edit]
1,3-Propanediol may be chemically synthesized by the hydration of acrolein, or by the hydroformylation of ethylene oxide to afford 3-hydroxypropionaldehyde. The aldehyde is hydrogenated to give 1,3-propanediol. Moreover, the bioconversion of glycerol to 1,3-propanediol is existent in certain bacteria.
Two other routes involve bioprocessing by certain micro-organisms:
- Conversion from [corn syrup](Corn syrup - Wikipedia) effected by a genetically modified strain of E. coli by DuPont Tate & Lyle BioProducts (See: bioseparation of 1,3-propanediol). An estimated 120,000 tons were produced in 2007".[3] According to DuPont, the Bio-PDO process uses 40% less energy than conventional processes,[4][5][4][5] Because of DuPont and Tate & Lyle’s success in developing a renewable Bio-PDO process, the American Chemical Society awarded the Bio-PDO research teams the “2007 Heroes of Chemistry” award.[5]
- Conversion from glycerol (a by-product of biodiesel production) using Clostridium diolis bacteria and Enterobacteriaceae .[6]
Ooh, only just caught this one. (replies coming too thick and fast for my little brain)
Well worth a trial. (and would be very intersted in the results) but do be careful not to make assumptions on that basis.
Strikes me that The PG content in MF might be low enough to be considerered merely a trace? (That might account for lack of acknowledgement) . and that being so , It might be that not even my highly sensitive bod has managed to notice it yet. But , like I said before, i wouldn’t count on that situation continunig. And I’m certainly reacting to something-or-other ATM., and my vape is making me cough a bit (I’m just not willing to include my vape in an elimination trial, ATM. I’ll try that , as a last resort, if everything else gets the green light)
Also, consider there are way too many variables involved : degree of sensittivity, underlying etiology (which, again, surely differs between indivduals ) and whether it’s the PG itself, or source material? (all-too-often unknown) . Hopefully, you can control enough of those variables to get meaningful ( and useful!) results, but then we can never safely generalise.
BTW, I’ve personally avoided PDO because it’s made from corn. So can’t add to the knowledge base there.
What MF flaves are making you cough ??? My understanding is not all have PG in them , however I could be wrong
currently, it’s a very old batch of Tangerine, and an equally old batch of Rum Truffle (containg MF rum and MF Dark Chocolate amongst other things. (The Dark Choc is already a bit of a calculated risk, you might say, because it’s somewhere between rare and impossible for me to find a chocolate I can tolerate. I’m not altogether certain I can handle cocoa , though the disappointments are probably due to hidden ingredients and/or cross contamination. I’d have to grinfd my own Cocoa beans to be sure! In short, i really wouldn’t leap to any conclusions! not even if I nailed to MF, and not even if that particular flavour had PG in it. )
The cough is not so bad. Very mild asthma perhaps, or mayvbe triggered by pure irritation, nothing more, since i’m trying to ease my way back into vaping after a recent lapse. Its my other symptoms, which are most likely due to ingesting corn in some form, that are really bugging me. and , no, you really don’t want to hear about those.
What I mean to say (in my long-winded fashion) is that MF is way down the bottom of the suspect list as yet. But I’d like to be forearmed with info in case it makes it’s way to the top. So thanks!
Not PDO …I had to confirm lol…
Sorry, couldn’t read the label, but happy to take your word for it. Not surprised. I wasn’t thinking of the PG that we (don’t) buy for ourselves, but rather of the countless other sources of PG, that @Plunderdrum and I would be (not altogether successfully) trying to avoid. That is, where Pg appears as an ingredient , or ingredient of an ingredient .
Btw, that’s by no means limited to vape juice and concentrates (though that’s the big concern on this forum ofc). It’s also in numerous foods, medicines , cosmetics, cleaning fluids, hair spray, nasal spray, inhalers, air fresheners, you name it. In most of those instances it would take some painstaking research to find out what the PG therein was derived from, or even if they contained PG at all (eg when it appears as an ingredient of an ingredient)
So, all in all, controlling your exposure to PG is a pretty difficult task, and keeping track of what ""kind " of PG you’ve been exposed to is just about impossible. PG is PG is PG, after all. The crucial difference (if such exists) would be in the impurities.
ummm. sorry @Nicotine_River , I’m afraid I have a bigger question.
I just looked at the picture on your website, and saw that it says “PG based” on the bottle. What gives? Pure MF are definitely not PG-based. indeed some of us started up with MF on account of PG-allergy , so this question really matters.
I suspect that’s just a labelling error? but I don’t want to just assume as much.
This will be changed by tomorrow once we get our team to make the changes.
OoH heck. sorry to be a flaming nuisance @Nicotine_River but that ingredient list on your website is all wrong, too. I mean totally wrong.
Ingredients: Extract from Co2, Natural and Artificial Flavor. Additives (e.g. carriers, preservatives, antioxidants): PG
There was definitely no artificial flavour in MF, last I checked . And these are not only natural , but organic. That’s surely worth mentioning?
Aso, my bottles of MF in my fridge say "NO ADDITIVES" on their labels, in bold. (I just checked, to be sure)
(BTW I got that list from the Raspberry Flavor page, but I imagine its the same for them all?)
@Nicotine_River, @jay210 is right about all of that ingredient wording. It’s as if you guys never looked at the MF website.
“Our flavors are cold-processed using extraction without the use of any colorants, fillers, diluting agents or preservatives.”
" Ingredient: genuine flavor extract*
*Apricot, Bergamot, White Cherry, Pink Grapefruit, Lemon, Lime, Mandarin, Orange and Rum flavors require additional alcohol extraction and may contain up to 5% residual grain alcohol."
This all seems very strange. I’m still thrilled that you’re carrying MF, just confused how so much incorrect info came with the roll-out.
Hello, we based all of our ingredient wording off of the SDS’s that were provided to us by Medicine Flower. However, we will still be making the adjustments to the labels tomorrow stating that they are water soluble instead so that it doesn’t cause any confusion!
Also, we will be rechecking the SDS’s to confirm that there are no typos or incorrect placements of words to be accounted for!
