The 4 Components of E-Liquids and Their Roles - What to Know

If you're a beginner to the world of vaping, you may assume that an e-juice is simply water and flavours with nicotine added to the mix. However, it is more complicated than it seems.

E-liquids, also called juices, are made of four different components: Propylene Glycol, Vegetable Glycerin, flavouring, and nicotine. In this article, we'll touch on these components and how they contribute to making an e-liquid.

Here are the four components of e-liquids and their roles:


Not every juice out there is going to contain nicotine. You know which ones don't by looking at the labels that state "Zero Nicotine" or "Nicotine Free."

Nicotine is a colourless substance that is found in the majority of juice. When absorbed by the bloodstream and carried to the brain, it can produce what some may call a "nicotine high." This happens because when nicotine interacts with the brain, the brain produces adrenaline and dopamine. This is what hooks most people to smoking and, in this case, vaping.


In the market, there are flavours of all kinds, from grape to even cheesecake! Whatever you have in mind, there may be a liquid that exists in that flavour. That said, there are three types of flavourings when it comes to liquids:

  • Natural Flavours
  • Nature-Identical Flavours
  • Artificial Flavours

As you can tell by their names, each is extracted from different sources. Natural flavours come from natural sources, such as plants. Nature-identical flavours are also derived from natural sources but are combined with other natural compounds to create a flavour profile. Artificial flavours are entirely synthetic, meaning that they are made in labs.

Vegetable Glycerin

Vegetable glycerin (VG) is responsible for carrying the vapour clouds. This is thanks to its stickiness of the liquid. If you're looking to create huge plumes of vapour, then a liquid with a high ratio of VG is the one to go for.

Propylene Glycol

Propylene Glycol (PG) is responsible for carrying the flavour and nicotine into the plume of vapour. PG it in itself has no flavour, smell, and colour, meaning that it entirely relies on the added nicotine and taste to pack a punch. Also, because it isn't as thick as VG, it won't create much of a cloud. However, its main strength, as mentioned, is to carry the flavour and nicotine into the vapour. Because of this, if you're more about enjoying a juice's flavour over creating vast plumes of vape to show off to your friends, look for liquids with a higher PG ratio.

Now that you know the four components of juices, you can buy your next e-liquid, confident that you're getting what you want. If you're looking for ones with nicotine, you know exactly how to, and if you don't want any nicotine, you know that as well.

Whether you're looking to create large plumes of vape to show off to your friends, or just want to lay back to enjoy the flavours of different juices, you know what to keep an eye out for.
