PG and VG, or Propylene Glycol and Vegetable Glycerine, are both substances found in many e-liquids. PG is a colourless liquid and VG is a thickening liquid that is also often colourless. Depending on the ratio, these ingredients can dictate the type of experience an e-liquid provides.

What Are the Common Differences between PG and VG in E-Liquids

Given both VG and PG are ingredients typically found in most e-liquids, encountering an e-liquid containing only VG or PG could be considered unusual. The type of vaping experience a device provides is partially dependent on the e-liquid and the levels of VG & PG within it - known as the VG/PG ratio, and most e-liquids contain a certain percentage of each substance. For example: an e-liquid could have a combination of 70% VG/30% PG, or 60% VG/40% PG.

High PG ratio e-liquids (typically above 60%), provide a stronger flavour experience. This is due to PG being a thinner substance - meaning it can dissolve quickly. As PG itself doesn’t often contain any natural flavour, it’s used to help to blend the other flavours within an e-liquid.

High VG ratio e-liquids (typically above 60%), provide less flavour, but more vapour production. Since VG is a thicker substance, more vapour is produced compared to high PG ratio e-liquids when VG is used as the majority base for an e-liquid

E-liquids with around a 50/50 of PG and VG split often offer a smooth vaping experience.

Another common difference between VG and PG is the nature of the substance itself:
PG is a synthetic substance with a longer shelf life and VG is an organic substance with a shorter shelf life. Learn more about the VG/PG ratio with the article What Does PG, VG Mean?

VG and PG are not usually the only ingredients in e-liquids. Nicotine, for example, is a substance that is usually present in e-liquids.

Nicotine in PG and VG E-Liquids

Nicotine VG and nicotine PG base products are commonly both available online. However, these are not usually e-liquids by themselves - they are ingredients that adult vapers can use to make their own e-liquid – which may be possible for certain vape devices designed to be used with certain e-liquids in this way. heck the vape device’s manufacturer guidance to determine which e-liquids are suitable for your device.

Which Device and VG, PG Ratio Is Right for Me?

Fundamentally, the type of device you are using matters when it comes to choosing an e-liquid. Many e-liquids are designed for certain vaping styles, and so are the devices. This means that particular vapes will match particular e-liquids. For example, a high VG e-liquid is likely to go well with a Sub-Ohm vape, for those adult vapers who desire a Sub-Ohm vaping experience. On the other hand, a high PG e-liquid typically works well with most devices – typically providing a stronger flavour.

PG and VG in IQOS VEEV

The innovative VEEV is a device where the PG/ VG ratio have already been set and predefined by VEEV. VEEV operates in a closed pod system, consisting of a battery and a pod, filled with e-liquid. There are plenty of flavours available for adult smokers. Discover the VEEV pods collection in the online store

Does VG and PG Matter in Heated Tobacco?

Heated tobacco works differently to vaping, and these products don’t usually require the use of e-liquid. This means there is no VG or PG to worry about. Instead, heated tobacco devices should heat tobacco.
