Propylene Glycol vs polyethylene glycol (PG vs PEG)

[sbmqcy]

What's the story. Wikipedia references both as a primary ingredient in eliquid. By my reading, it is propylene glycol that is GRAS. Polyethylene glycol? Are both used in eliquid? Is it confusion and only one is used?

I started vaping on V2s, and I got super congested. (Same time as quitting analogs). I did some reading and thought maybe I was sensitive to PG, so I've only vaped 100%vg juices. I wonder what V2 uses, and whether I might be able to try some PG containing liquids to see what happens.

I am not aware of them using PEG in ejuice. PEG is Polyethylene glycol. We use Propylene Glycol. Wikipedia is notorious for their inaccuracies. I have never seen PEG in any of my juice. PG yea but that is Propylene Glycol. Different thing.

I haven't seen any e-liquid sellers claim PEG on any ingredients... where did you see that, or who is selling that?

Hi all,
totally wicked in the uk and here in the US uses it. At least you can buy it from them. It is more expensive so that is probably why PG is used instead of PEG..

I hate to say it, but this time Wiki is correct. I have seen PEG used in limited juices, primarily over seas. It has many of the same uses as PG, but I believe you will find its largest use is in the laxative and stool softener OC medicines. I personally have not tried it in any of my mixes. Maybe someone else has.

I'm a asthma sufferer and I found that by limiting PG has helped me a lot with the fluid congestion. I am unable to eliminate it entirely since my favorite flavors are diluted in PG (ie Loranne, TFA, etc.) I find that if I mix my stuff at around 80% VG or greater I do a lot better. I may try to go even higher the next time I purchase my NIC. It think I'll buy it in a VG base instead of the PG base I have now.

Hope this helps.

Forgot to mention I am a member of Wikipedia and while they are great it is a primarily volunteer service there is no screening and I can go in and add something even if it's wrong. I sent them a message mentioning that I feel this is an error. I don't feel qualified to go delete that entry. LOL

You can find a lot of stuff in eliquid from overseas especially in the Far East. That is why I don't buy liquids from there. You won't find that in any Reputable Eliquid. I've heard of laxatives being used in Eliquid so I guess that was it. But it is not used buy the good guys. Another reason that 90% of my eliquid is DIY. I would not be surprised an anything you found in that stuff from the Far East.

Some of the more knowledgeable vapers here should set the record straight on wikipedia as far as safety and research that actually has been done on e-cigs. That's probably where any layperson will get their information from and form their first opinions about them. It would be good to have a solid, positive representation of them with links to good research articles for those who care to verify.

 

[sbmqcy]

I saw several posts here that reference polyethylene glycol. That's where I first started to wonder and looked at Wikipedia. I initially assumed it was an error on the individuals' part, but then I saw the Wikipedia article.

Relying on Wikipedia for scientific fact is like asking Atilla the Hun advice about human rights issues. You just don't do it.

Sorry Steve but you're wrong--Sugar and Spice is right! Decadent Vapours, one of the best British eliquid providers, also carries PEG:

Diluents

I am a contributing member of Wikipedia. I don't make changes but I could. I sent a message challenging the information. They are not like the old Encyclopedia. Not to many paid people. So they do make mistakes. FYI I had no background check in order to join. I just make a donation every so often. My College major was Architecture not publishing or Journalism. If that will give you an Idea.

Ok I stand corrected. But it must be uncommon as I have bought a lot of juice..

No actually it is used on the other side of the pond. Some UK sites I've been on have PEG juices.

Haven't seen any available in the US. Dunno why. Don't know exactly what PEG is, just that it's used in some overseas e-liquids...

 

[BardicDruid]

PEG is commonly used to thin eliquid, it doesn't take much to do it that's why they use it.

 

[steved5600]

I did some further research LOL asked someone in the know about PEG400 which is used by some companies. PEG is considered to be an ACTIVE ingredient and not a neutral one. It may taste better but I don't want it in my lungs I don't even like much PG in my juice.

 

[Slots]

I don't even like much PG in my juice.

... PG is a germicide.
With regard to PG, if you were born in a hospital, the first breaths you drew on this earth were well laced with PG -- it's been in use in hospital ventilating systems for many decades.
PG is a germicide. Because of the PG scum problem, it's mostly been replaced with micropore filters.
Also, many surgeons and OR nurses have spent 12 hours per day, five or six days per week in operating theaters for their whole careers, and operating theaters used to get really heavy doses of PG via the ventilation systems.
And an awful lot of stuff we breathe, put in our mouths or eat are well laced with PG.
The FDA has called it "generally recognized as safe."

Is the basic ingredients in Sno-Cone, as it makes the flavoring "stick" to the ice.
Used in asthma inhalers, babyfood, pills, all kinds of food in the grocery store, in cosmetics like lipstick etc etc
Ever been to a disco, or concert with a "fog" machine ... vapor, duh, PG,VG, or both are used
All FDA approved.
Not that that in it'self is reassuring !

Poly (ethylene glycol) is a more accurate expression of PEG as it is a repeated chain of Ethylene Glycol. Apparently PEG is non-toxic, biologically inert and hydrophilic, but I'd steer clear. I know for a fact that Ethylene Glycol is super toxic.

As Slots said, I wouldn't worry about PG unless you are having problems with it. PG metabolizes in four hours and there's no bioaccumulation.

Not to make light of your concerns, but that does remind me of the old chem joke:

Two chemists walk into a bar. The barman asks one "what'll it be?", and he responds "I'll have a H²O". The barman hands over a glass of water and turns to the second: "and for you?". "I'll have a glass of H²O too." Barman hands him his glass, both down their drinks, and the second chap drops dead.

[Spoiler: H²O² is hydrogen peroxide, commonly known as bleach]

Anyway, point is I'd be wary of warning people off PEG purely because they could have mucked it up and put in a different compound (or version of), same can be said of anything. I do get your point, and it's a valid concern, but we have enough it's-harmful-if distractions floating about, better to focus on what it is than what it could be in the wrong hands, and stick to vendors you trust not to forget to carry the one.

 

[ZombeApocalips]

I get your point. I was just trying to explain the chemistry between PEG and PG. Yes, h2o2 is not so good for drinking.

The only reason I warn people off of any of the propylene glycol or polyethylene glycol is because some are sensitive to it, all experience dehydration (thus the need to increase water intake), and the fact that minor chemical changes equate to a huge difference in effect, as illustrated by your joke.

That is all certainty. That said, I'm not a scientist or e-cig guru.
