Anyone with PG allergies ever try PEG400 and have it be OK? Not sure what the real difference is.

Itās a sensitivity not a allergy 
Peg400 is for the other āoilsā we donāt speak aboutā¦here lol
It wonāt work with regular eliquid, as short answer.
However thereās apparently a liquid out there, that steeps faster, gives higher flavor and can be used like pg, but isnāt pg. I think chemovatic sells it? I will look into it, only heard about it couple months ago and forgot all about it lol.

PDO is what I could find on the Chemnovatic site. Is this what you are referring to?
I remember ppl blaming PDO for flavor fade on the RFSC threads. This is 1,2 propanediol, and I think Walt was using 1,3 propanediol. Oddly, when I googled 1,2 peopanediol wikipedia says is another name for PG!
Hmmm.

I canāt remember but Iāve it book marked at home. All I heard was, itās not pg, it āsteepsā your juices faster, sold in Europe and better flavor carrier.
Too me it sounded so stupid that I didnāt look further into it. You know like when someone says go on the roof your juice steeps faster, all you think off is : yeah right!
But Iāll post the link tonight if I can find it. Sorry for not being much more help atm.

That is funny! Iād ignore that bit as well. An alternative to PG that works is of interest, though!
They say āAllergy free: dedicated for people with allergies or sensitive to pertroleum-based substancesā
umm, it always annoys me when things are marketed as āallegen freeā cos thereās no such thing . Whatever the substance , you can probably find somebody somewhere in the world whoās allergic to it! That said, , Iāve nothing against this partuicular manafacturer, on that count. They all do it!
More annoyingly, the stuff is made out of unspecified āvegetablesā, as they very clearly and e4xplicitly assume that PG senstivity is due to the petrochemical origin. So who would care what vegetables they use, eh?
Good grief! That is one huge- and quite possibly false- assumption.
This post triggered a little burst of research on my part into how these various PG -related sunstances are made (so thanks for that!) And I fouund out that, increasingly often they are made from cornā¦and that includes PG itself! You certainly canāt assume a pertrochemical origin for PG. And that might be the real problem
I found speculation from some PG-allergy sufferers who happened to also be sensitive to corn that these two . seeminly different sensitivities are just two faces of the same thing, at least in their case. That gives me pause for thought Iām also sensitive to both PG and corn. And Iām wondering how many others ? Corn sensitivity is pretty damned hard to uncover, because corn is added to almost every damned thing, and doesnātt always appear on the label. You might pick up on the fact that youāre having bad reactions to a whole host of processed foods, cosmetics, medicines etc, but tracking down the culprit is insanely difficult, especially if youāve never even heard of corn sensitivity. (which is the exact boat I was in, a few years back , when my corn troubles started)
Iām now wndering if I can safely vape PG which actually does come from petrochemical sources? But who the heck ever tells you what theyāve made their PG out of? Thatās a million miles from being a labelling requirement. So Iāll just have to go on wonderng, I guess .

I would think the official scientific explanation would tell us that 1-2 propandiol (which is PG) is that chemical and nothing more regardless of the source material the end result, chemically speaking, is the same. I do not trust science or the FDA however

Agreed 
thereās always something that āscienceā never thought to take into account . And when most research āscientistsā are in the pay of Big Industry , you can multiply that factor one hundredfold *sigh *. One way or another, they just get the results they want, donāt they?

The chemical is the āsameā (PG and PDO) but the molecular structure is ārotatedā. Same is true of Starch and Cellulose ā¦exactly the same āchemicallyā but the glucose molecules are alternately rotated in Cellulose. The difference is one is PAPER (cellulose) and one is food (starch). Termites can eat wood (cellulose) because they have a bacteria in their gut that can break the bonds of cellulose making it digestible as glucose ā¦most other animals cannot (Ruminants can).

I believe you misread or misinterpreted my sentences, good sir. I stated that PG whether derived from petroleum based sources or vegetable the end result is still chemically speaking still just PG. PDO is indeed a different animalā¦

Apologies my friend, that was not intended as a correction, just an attempt to clarify overall. I tried PDO for a YEAR and I count it as lost time ā¦but then I donāt have a PG sensitivity. I was just looking for a better ācarrierā flavorwise, and it was not. The āfadeā thingy was real. It seemed better at first (SnV) but usually ended out weirder over time. It wasnāt bad ā¦it just wasnāt better. It became unpredictable (steeped Custard flavorwise) ā¦and expensive, but I wasnāt looking for a solution to my PG sensitivity. It might be a solution for that (because the molecule is rotated), but I have zero insight there. Bro Hugs

All good, wanted to clarifying my opinionā¦ Yes i heard PDO was responsible for flavor fade and it was speculated that was a problem with RF SC flaves. Whether it was PDO to blame or simple overflavoring is still up for debate as peoples percentages where all over the map. I have considered Trying PEG(not food safe though correct?) And or PGA and would like to experiment with 0.5-1% DW as wellā¦

RF was putting out flavors with PDO instead of PG before they offered the current SC line
Is that what was in the āextractsā then?
Edit: lmao i remember now they were having people test out PDO flaves, before the extracts, then followed the SCā¦
