When it comes to e juice, some people never think about what's in it—they just notice how thick and rich the vapor is, and how much flavor it has. If you've ever heard vapers talk about PG, VG, or PG/VG blend, however, you've come across one of the important parts of how e juice is made: whether it uses propylene glycol (PG), vegetable glycerin (VG), or a blend of the two.
Both PG and VG are commonly used in vape liquids as a base, and both can be found in a wide range of consumer products, from foods to pharmaceuticals.
All our e juices include a base—either PG or VG—along with water, flavoring, and nicotine (except in 0% nicotine e juices, of course). The base is what gives the e juice its consistency, carries the flavor, and produces the vapor. Here's a little more detail about what these common bases are and the benefits of each one.
PG (Propylene Glycol)
Propylene glycol is the most common base for e juices. It's thinner, which makes it easier to clean up, and it doesn't cling to the inside of the tank or gunk up the coil as much as VG can.
Because it's a "humectant," PG is great at holding moisture. When it comes to vapor, that means it's perfect for delivering a strong throat hit with lots of flavor. PG has no taste of its own, so it won't affect the flavorings that are added to it.
One drawback is that some people are allergic to propylene glycol; if you suspect you're having a reaction, stop and try an e juice with only VG to test your suspicions.
VG (Vegetable Glycerin)
A little thicker and sweeter than PG, vegetable glycerin has a taste of its own that can affect the flavor of an e juice. While its thicker consistency can make it a little messier to clean up, it does tend to last longer because it drips more slowly into the wick.
But the real bonus of VG's consistency is that it creates a thick, rich vapor. This does detract from the throat hit, but some people prefer that anyway. However, for the best combination of flavor, throat hit, and vapor thickness, a PG/VG blend is the way to go.
As we mentioned above, a blend of PG and VG creates a vapor that is thick and rich, yet delivers the throat hit and flavor that every vaper is looking for in an e juice.
