what's the difference

[christina7]

between "propylene glycol" and "Pure Glycerin" ? I have the pure glycerin (usp) that I got a time back when I just started vaping. I would add a few drops to my carts to extend the liquid before I learned about e-juice. Now I just read somewhere where someone puts a few drops of PG in his atty at the end of the day to preserve it. But I"m wondering if I got the right stuff. The both have the initials PG. but the little explanation that pops up is propylene glycol...

thanks kindly,

When glycerin is discussed on this site it is usually refered to as VG, or vegetable glycerin, since it can be a vegetable derivative. When you see PG here, that is propylene glycol. The pure glycerin you have refers to the fact that it has no other ingredients, so it would be pure VG here. I hope this helps.

Glycerin is VG. VG is a bit thicker then PG But if you cut it with some PGA it should do the same thing. Even the way it is now might be ok but i would cut it a bit if it was me.

And VG will give you more vaper and it will hang in the air much longer.
