E-juice has four main ingredients: propylene glycol (PG), vegetable glycerin (VG), flavoring, and, depending on what you’re vaping, nicotine. If you’re new to the world of vaping, you’re probably not too surprised to discover that e-juice contains flavoring or nicotine, but you may be wondering what in the world those chemical compound sounding terms are… especially since they’re in a product you’re inhaling. So, here’s a little information on PG, VG, and the difference between the two.


PG is a thin liquid with no odor or taste. It’s added to lots of products that go on human skin and in human mouths, including toothpaste, mouthwash, and skincare products. The FDA has certified PG as safe to ingest orally and approved its use as a food additive. One of the purposes in adding it to e-juice is to give vaping that throat hit.


VG is a thicker liquid with a distinctly sweet taste. VG is also recognized as safe by the FDA as it is a benign substance. It’s a common additive in baked goods and sugary sweets and is even frequently used in medicines.

PG vs. VG

E-juices are all comprised of some combination of PG and VG. Different ratios have different characteristics. Juices that are high in VG produce larger clouds but don’t have you feeling much in your throat, while juices that have large amounts of PG deliver strong throat hits but lead to relatively small exhalations. All the different ratios in between represent different manifestations of the balance between these two main types of e-juice. The perfect sweet spot is different for everyone. You’ll have to try different ratios until you find out which one is right for you.

Luckily, all of our e-liquids come with adjustable PG vs. VG ratios, from 20% VG to 100% VG, so you can experiment away and find your ideal e-juice.
