One of the most common questions we get asked on support chat is: what is the difference between PG and VG? We wanted to create this simple infographic to give you the basic overview.
We know that many people have heard the claims that elquid (or vape juice) contains anti-freeze, and that is simply not true. Do not confuse PG (or Propylene Glycol) with the very toxic Ethylene Glycol that is found in most antifreeze products. To be fair, PG is used in some antifreeze applications, such as in food-processing systems or in water pipes in homes where incidental ingestion may be possible.

Now, back to the main point of this article. PG, VG, and vaping - what's the difference?
ALL eliquids contain four basic ingredients, which are: PG (Propylene Glycol), VG (Vegetable Glycerin), Nicotine (unless you get 0mg), and flavoring. We do know that there are some eliquids marketed as 100% VG, and that may be possible, but we can tell you that the vast majority of flavorings on the market are concentrated flavors that are diluted in PG.
Knowing that all eliquids have the same ingredients, you need to determine how much of each of those ingredients would be best suited for your vape. Over the years in the vape industry, many new terms have cropped up that may seem confusing. "tank blend", "dripper blend", "Max VG", 80/20, 70/30, etc. It can all be very overwhelming for the new vaper. Let me try and decode the mystery for you.
The 'blends' are actually the ratio of PG to VG. It used to always be stated as PG first, so for example 80/20 would mean that the liquid is 80% PG and 20% VG. Somewhere along the way, the standard got blurred and now you would actually have to ask what the ratio is. 50/50 is the easiest of course. Tank blend typically indicates that it is a higher PG than VG. Dripper blend would mean more VG. Most manufacturers have taken to just describing their liquids as Max VG which usually means that the liquid has as much VG as possible without losing the flavor profile.
To make this simple for you, if you are using an older style vape, such as a model that looks like a cigarette or slightly larger like a pen style eGo model, you are going to want to stick with liquids that are higher in PG. As you can see from the graphic above, the flavor will be awesome, but you won't get as much vapor.
If you are using a vape mod or box mod with a subohm tank or a rebuildable atomizer, you will want to go for the higher VG liquids. You will get lots of vapor out of these liquids with the right setup.
I hope that you found this guide helpful in understanding the difference between PG and VG.
