PG vs VG

Two terms usually pop up when e-juice is mentioned; Propylene Glycol (PG) and Vegetable Glycerin (VG). Novice vapers may find these terms confusing. However, having knowledge of these two e-liquids could really make your vaping experience enjoyable.

Here is a simple guide of all you need to know about PG and VG.

What PG and VG are?

  • Non-intoxicants: PG and VG are both odorless liquid substances which are combined with nicotine and a variety of flavors to create or produce e-juice. As much as they are classified under the same alcoholic chemical mass, they aren’t intoxicating. To be precise, they are categorized as sugar alcohols and are used in many liquid consumable products.
  • Vapor-producing: When heated, they produce vapor which makes it easy for them to be inhaled. Thus, it makes it easier for vapers to easily take vaping sessions in convenient places.

They don’t cause medical problems that inhaling oils do: PG and VG are not oils and they can’t cause the same medical problems that inhaling oils can cause such as lipoid pneumonia.

  • Difference: These two liquids have slightly different taste and they also differ in terms of consistency. They also have a distinct sensation in the mouth and throat when they are vaped. Moreover, a plethora of e-liquid combines PG and VG in its production, but the ratio in quantity varies.

It is also essential to note that some vaper starter kits can work with a specific level of PG and VG. Also, choosing the wrong PG/VG ratio can have a negative impact on novice vapers. Thus, you must be careful in choosing the appropriate level.


Now that we’ve looked at PG and VG peripherally, let’s look at them each in detail.

What exactly is PG?

PG is a petroleum by-product fluid which is colorless, odorless, and less viscous when compared to VG. While vaping it provides a ‘throat hit’ which many users claim to have a similar effect of tobacco-smoking. It is more effective in carrying flavors and it is often used as a suspension fluid for nicotine and different flavor concentrates.

It is used for:

  • Toothpastes and other oral hygiene products
  • Oral medical products
  • Nicotine inhalers
  • Beauty products
  • Lots more

SAFE?

Studies, as well as the FDA (Food and Drug Administration) has shown and deemed it safe for ingesting orally.

What exactly is VG?

VG is a natural chemical which is extracted from vegetable oils. It is often used in the production of e-juice or e-liquid to thicken the produced vapor during vaping. It has a slightly sweet taste and it has more viscosity than PG.
VG offers a smoother ‘throat hit’ than PG which makes it suitable for sub-ohm vaping.


It is used for:

  • Sweeteners products (sugar replacement)
  • Beauty products
  • Soap and hand cream
  • Toothpaste and other dental products
  • Lots more

SAFE?

The FDA has categorized it as “generally recognized as safe.” Given the fact that it is used in food and medicine, it is quite safe for human consumption.

Final Thougts

It is quite simple to grab the basics of PG and VG. They work differently and the ideal thing in using them for vaping if you’re starting out will be to begin with a 50-50 PG/VG ratio before trying different combinations to detect your preference.
