PG in antifreeze?

[raverreturns]

So, no doubt this topic has been handed around before, but my limited search techniques came up pretty scarce for this site. When I Google "what is propylene glycol" I got a myriad of sites stating that it is something used in antifreeze and some cosmetics, soaps, etc. Most sites said that it is dangerous and something to avoid. Since I am new to this, I'm still learning about all that I can. What are peoples thoughts on this?

Now that I am learning more about ingredients and checking sites for which ones have which main ingredient, is there a simple way to explain what is the difference between PG and VG pertaining to usage? Does one perform better than the other? Are there any health concerns pertaining to one over the other?

PG is used in RV antifreeze that has to be safe for human consumption as it is used to winterize pipes. Ethylene Glycol is what is used in automotive antifreeze and is highly toxic.

Here is one site I found that lists some of the uses of PG. You want to make sure you are getting USP grade.

Propylene glycol is used:

* As a solvent in many pharmaceuticals, including oral, injectable and topical formulations. Notably, diazepam, which is insoluble in water, uses propylene glycol as its solvent in its clinical, injectable form.[5]
* As a humectant food additive, labeled as E number E1520
* As an emulsification agent in Angostura and orange bitters
* As a moisturizer in medicines, cosmetics, food, toothpaste, mouth wash, and tobacco products
* As a carrier in fragrance oils
* As an ingredient in massage oils
* In hand sanitizers, antibacterial lotions, and saline solutions
* In smoke machines to make artificial smoke for use in firefighters' training and theatrical productions
* In electronic cigarettes, it is used to deliver vaporized nicotine
* As a solvent for food colors and flavorings
* As an ingredient, along with wax and gelatin, in the production of paintballs
* As a moisture stabilizer (humectant) for snus (Swedish style snuff).
* As a cooling agent for beer and wine glycol jacketed fermentation tanks
* As a non-toxic antifreeze for winterizing drinking water systems, and in applications where the used antifreeze eventually will be drained into the soil, water, or a septic system.[6]
* As a less-toxic antifreeze in solar water heating systems
* As a solvent used in mixing photographic chemicals, such as film developers
* In cryonics
* As a working fluid in hydraulic presses
* As a coolant in liquid cooling systems
* To regulate humidity in a cigar humidor
* As the killing and preserving agent in pitfall traps, usually used to capture ground beetles
* As an additive to pipe tobacco to prevent dehydration.
* To treat livestock ketosis
* As the main ingredient in deodorant sticks.
* To de-ice aircraft.[7]
* As an ingredient in UV or blacklight tattoo ink

Propylene glycol has properties similar to those of ethylene glycol (monoethylene glycol, or MEG). (Note: Infrequently propylene glycol may also use the acronym MEG, but as an abbreviation of methyl ethyl glycol- the industry standard acronym for propylene glycol is PG or MPG (monopropylene glycol)). The industrial norm is to replace ethylene glycol with propylene glycol when safer properties are desired

Lots of good information. Thanks, guys. What about the people's experience with PG and VG in e-cigs? I'm sure it's to one's own preference as to which is better, but I was wondering what differences can someone expect from vaping either one over the other.

You could search for info here in the forum. Results would probably be more applicable to e-cigs and vaping. Try a search for the keywords "propylene glycol" in threads here using the search button near top of screen.
E-Cigarette Forum - Search Forums

When you are done reading those (around August or September)
Try the same search using "Vegetable Glycerin".
When you are done reading those (around January or February of next year),
the replacement PEG will probably be considered acceptable for vaping.

Most people say that PG is good for throat hit and VG is good for vapor production. I've tried both, and PG is it for me

yeah what rocket said!!!! and I also rock the 100%pg

 

[justwonderin]

I'm fairly new to vaping and I do want to say that the things I have read here so far have a lot of great info...thanks

Hey, Raver!
If you have ever been to a rave you have already been breathing PG. I used to own a rave venue in Atlanta, and breathing PG for years (fog machines). They even have scented fog juice.

glycerin both VG and PG are used in just about every way as water would be an it just as safe. glycerin is axualy more usefull then water is come cases.

What truly matters is that when you vape enough it keeps you warmer in the winter!

 

[portguy]

If my kid can drink a cough syrup that is about 89% PG i think i can vape it.

 

[vandrixfly]

I was addressing this concern myself a few months ago until I went to work (I manage a breakfast restaurant) and found that PG is the second ingredient in common table syrup. It's safe for you, your kids, the elderly, and pancakes I wouldn't worry about the safety of consuming PG.

"the theory" is we don't inhail crest into our lungs.

But people with asthma inhale PG all the time from inhalers and nebulizers. And it's used to suspend the medicine they give lung transplant patients to inhale. I think if it's safe fro them it's safe for me .

Its also used in misters (things which spray fine mist) in hospital wards during a swine flu breakout - its antibacterial properties are supposed to help. And its in my neightbour's 'resuce inhaler' for his asthma. If its safe in those I'm not worried.
As for which is better to vape - well its very much personal preference I think. I usually have 70-80% PG and 20-30% Vg in the majority of my juices. I have tried all PG (was ok) and all VG(same) - my choice tends to be based on flavor not suspension medium makeup

Propylene glycol is FDA APPROVED. It is said to be a food-grade additive meaning it is SAFE for consumption.
