I see that they all have the same molecular formula. So does it matter if it's made from vegetable oil or petroleum? assuming USP grade?
thanks

Is vegatable glycerin same as glycerol, which is same as glycerin produced from petroleum?

Glycerol - Wikipedia, the free encyclopedia
VG is derived from plant oils.

I understand that it can be made from vegetable oil, but it can also be made from animal fat, or even petroleum product, but it seems the end result is same, they all have the same molecular formula. So as long as you don't care if it's "vegetarian" or "kosher", then it's practically the same isn't it?
For example, ethanol is the same whether it's synthesized in a lab or distilled from grains.

Vegetable Glycerin is made from vegetables. Glycerol may have animal products used in the making of it.. At least that is what Wikipedia says. Two different things. VG is all vegetable. So if your asking If you have made up your mind so be it. LOL
Glycerine is identical no matter where it came from--animal, vegetable, or mineral. Glycerol is just another name for it.
Whether I produce glycerine when soapmaking using coconut oil, palm oil, or rendered pig fat doesn't make any difference to the molecule (it does to the amounts of lye used to break the triglyceride into glycerine and soap, however, as the saponification index differs for each fat used). A chemist can't determine the difference between them (there is no difference) given only a sample of the resulting glycerine. One could, of course, if given the entire soap.
However, to call it vegetable glycerine it has to have a 100% vegetable oil used in production.
Fun fact: The story about glycerine crystallation that floats around (just cool to 17 C!) isn't true. The uncrystallized glycerine in my fridge, at 1 C, puts the lie to that one!

If you want to make sure you're getting vegetable glycerin, look for kosher USP glycerin.
Well considering the price of gas the last time i drove by the gas station, I'm pretty sure it's safe to say they're not using petroleum to make vape juice. Though that might explain the prices some people want to charge.
The determination by whom ever that Glycerol and Vegetable Glycerin are the same is dependent on their ability to measure that difference. Science is not as absolute as they like to think. Every time they think they have reached the peak of a mountain they find later there is yet another. I would rather er on the side of caution and use VG and to a lesser degree PG than Glycerol. Only reason I can see to use glycerol is because it's cheap. Is it worth that savings. Not for me.
