Specifically, here in the middle.
e-liquid

E-juice, e-liquid, juice - the liquid nicotine that you fill your cartridges with.
DIY - Do it yourself (homemade e-liquid mixture)
PG - Propylene Glycol
VG - Vegetable Glycerin(Glycerine = glycerin = vegetable glycerin(e) = glycerol)
PEG - Polylethylene Glycol
I'm sorry about the abbreviations. I try not to use them as much as I do.

Dow Chemical is a major supplier of Propylene glycol USP. The Dow product is Kosher and Halal compliant.
Propylene Glycol USP/EP | Dow Propylene Glycols

Glycerin USP is by definition vegetable-derived. Humco is a major producer of Glycerin USP found in US drug stores. Calling Glycerin USP "VG" or "vegetable glycerin" is a marketing ploy and confuses identification of pharmaceutical (USP) grade glycerin. Glycerin is also called glycerine or glycerol.

Only USP grade propylene glycol or glycerin should be used for vaping.

Propylene oxide is used in the production of propylene glycol which require further purification to yield propylene glycol USP.

Propylene oxide is derived from propene which a petrochemical (fossil fuel) product.

Propene is produced naturally by vegetation, particularly certain tree species.

Glycerin USP is by definition vegetable-derived.

Not exactly. Glycerin can be made from just about any biological source, including Pig Fat.
Dow Chemical makes millions of gallons (plants now operated overseas) of synthetic Glycerin called Optim made from similar petrochemical sources as Propylene Glycol.

I would be less concerned with how it is made and more concerned with its history of being safely used as an inhalant. PG vapor is used in hospitals to delivered inhaled medications, even for lung transplant patients. It's also used in concert fog. And it has been used in asthma inhalers and nebulizers since the 1950's.

PG is thin and lets through the most flavor and nicotine hit, as well as the most nicotine irritation. VG is thick (too thick to work alone in many popular methods of vaping), dulls everything PG lets through and adds thicker visible vapor. Most people use blends. I use high-PG blends like 80PG/20VG in cartomizers.
