well, people use 100% VG for their eliquids all the time. So if it's vegetable food grade glycerine, it should be fine. As far as chemical formulas go, they may have similar compositions but you can't just go by that as far as being able to switch one for another. Meaning that just because C3H8O3 is only one number off C3H8O2, doesn't mean they're interchangeable.
I copied this from a website cause I'm not that smart. But it looks like you can use it to me. I hope this helps. If not, I'll google some more. heehee
I thought I would throw my 2 cent chemistry knowledge in here. ALL GLYCERIN is produced from vegetable or animal fat/oil. Mostly vegetable, therefore food grade or reagent grade are both the same thing chemically speaking (C3H8O3), just different levels of purification to remove the free anions. Glycerin is not produced from petroleum.
i.e. food grade is just that, acceptable by FDA standards for human consumption.
USP [United States Pharmacopeia] is a higher grade, and suitable for human consumption (like to thicken cough syrup and make it taste a little better, also used in booze like schnapps etc...to give a better mouth feel) and cosmetics.
Reagent Grade is of highest purity and used mainly in chemical analysis preparations where any deviant anions would skew results in an experiment.
So basically, use whatever is available and suits your personal tastes or belief in safety level.

So it says it's glycerin but not whether it's vegetable?? According to the above post, it should be fine and I've heard that elsewhere as well. But maybe for peace of mind, wait to see what the manufacturer says?
This is why before I buy any VG/PG or flavor, I make sure that they are ok to vape specifically. Like the last place I purchased from is an aromatherapy supply website, but there were reviews on there from people that use it to vape... so I knew it was ok, on top of it being listed as food grade.

Let me know what you find out. After googling... I'm not sure but I'm sleepy now so good luck. Sorry I couldn't help but I'm sure someone will be glad to help you.
Based on what I remember, you should be able to use them interchangeably. When the fiancee gets back from work I'll ask her since she actually has her degree in Chemistry.
So I asked her. She said they are similar but she wouldn't use it in place of PG because it is a different structure so it won't react the same way PG does. It could be major, it could be unnoticeable, but she doesn't feel like figuring it out right now haha.
propylene glycol and veg glycerin are two different things all together. and SHOULD have two different compositions. together they are used in for vaping and not sure how one could be substituted for another.
you can make juice with one, the other or both no need to substitute anything.
