A Comprehensive Explainer When It Comes to E-liquid Part 1

As the name suggests, e-liquid is a solution that comes in a plethora of flavours. It's what helps e-cigarettes to get going. It's added to the kit's vape tank component; the heated liquid then evaporates. That's how vapour, which is water-based, comes about. This is what users ultimately end up exhaling and inhaling as they vape.

E-Liquid: What Ingredients Do They Contain?

Five or six years ago, those steaming-hot puddings you ate at school were your favourite food! 

If someone had asked you what you had for lunch, you probably would have replied: “Burgers and pies and some ice cream.” If you're not the kind of person who likes stretching to more than a few words, you’re in luck. E-liquids only have three ingredients!

1. Flavouring - This may very well speak for itself, but it's worth expounding on. There's an incredibly basic formula involved when it comes to e-liquid flavours. Flowers like roses, drinks like coffee and even tobacco in e-liquid come from that simplicity. PG and VG's two core ingredients are taken, then taste is added in. When there are no flavourings, then e-liquid really won't fly off the shelves at all. The whole vaping experience then becomes not as enjoyable, if not wholly questionable.

Common flavours include:

  • Apple
  • Banana 
  • Coffee
  • Cotton candy
  • Grape
  • Mint
  • Tobacco

2. Propylene Glycol - The term 'propylene glycol' (PG for short) sounds like a complicated chemical, but propylene glycol is completely harmless. Propylene glycol is a clear, syrup-like liquid that has no odour or colour and practically no taste. Propylene glycol is found in a range of everyday items, including deodorants, cosmetics, and designer dyes. It is used in adhesives, and it carries flavours very well when mixed into e-liquid. Propylene glycol produces a throat hit when vaped on its own.

3. Vegetable Glycerin - Often shortened to VG, it's odourless, colourless and tastes quite sweet as a liquid. It's a chemical "alcohol" that goes a long way. Unlike PG, it's far more viscous and incredibly thick. This is largely what makes it responsible for vapour production. VG is usually found in aftershave, cough syrups, food flavourings, ointments and toothpastes. 

Ingredient Safety 

PG and VG are seen as safe for the most part in the United States by their Food and Drug Administration (USFDA) It should be noted, however, that VG is recognized as alright for the most part. Putting VG on skin can trigger allergic reactions. However, these are all topical and oral! Since vape juice isn't swallowed or placed in moisturizer, it's generally fine.


E-liquid plays a major role in the whole vaping experience to the point that it can make or break a person's whole experience. It has countless flavours available, despite essentially being made with three ingredients only every time. In this section, we've covered the basics alongside ingredient safety in the general next. We'll explore e-liquid even more, including the importance of PG/VG ratio alongside what role nicotine plays in all this, among many other factors. Watch this space!
