E-Liquid Ingredients: What Goes Into Your E-liquid?

e-liquid ingredients

Ever wondered what e-liquid ingredients you’re vaping? This blog will lay that out for you, we’ll first briefly mention the four main ingredients you’d find, propylene glycol, vegetable glycerine, flavourings and nicotine (optional).

E-Liquid Ingredients

Propylene Glycol

A very important e-liquid ingredient, propylene glycol. PG  is a thin, odourless liquid which carries the flavour of e-liquid. It also provides the ‘throat hit’ feeling that a lot of new vapers strive to get when they make the switch from smoking to vaping. 

In addition, ts thinner consistency makes it easier to vape. You could find PG in everyday items as food enhancers for the same purpose (maximising flavour). 

Vegetable Glycerine 

Vegetable glycerine is a thicker, odourless, and sweeter liquid which is responsible for vapour production. VG is added into e-liquids to make them smoother to inhale and adds a thicker consistency to your e-liquids.

Similar to PG, VG is also used in a variety of household items such as caramel, soap and toothpaste.

Thousands of flavours exist from all types of flavour profiles in the market. You could get any flavour you could possibly want, from coffee, tobacco, dessert to exotic flavours.

Additionally, there are over thousands of chemicals that go into creating the flavours, however one chemical to avoid at all costs is diacetyl. Diacetyl is commonly used to create that buttery texture in popcorn. Vape manufacturers used to add diacetyl to their dessert e-liquids for that same reason.

In theory, this chemical is deemed safe to ingest, however, there has been evidence that inhaling diacetyl can trigger an incurable condition, Obliterative bronchiolitis, also known as ‘Popcorn Lung’.

Nicotine is the addictive e-liquid ingredient that you would find in traditional cigarettes. It stimulates the central nervous system and raises blood pressure, respiration and heart rate. 

Furthermore, nicotine stimulates the brain, it enables the release of dopamine, a neurotransmitter that plays a role in how we feel pleasure. E-liquid manufacturers tend to release their products in varying ranges of nicotine content, from 0mg to 20mg making sure it follows the TPD compliance.

How Does the Blend of PG:VG Work? Which Should I Choose?

We’re going to start off with saying that there’s no optimal PG:VG ratio, as it all depends on what you want to receive from your vaping experience. Here are a few things to look out for when looking at which blend to go for:


If you’re looking to get as much flavour as you can from your e-liquid, you want to choose an e-liquid with a balanced PG:VG ratio, so a 50:50. You could also go for an e-liquid that has slightly more PG in the e-liquid as it carries the flavour, however keep in mind that the throat hit will also be more pronounced. 

Throat Hit

If you’re looking to get an intense throat hit, any e-liquid that has a higher ratio of PG will do. Look around for PG:VG ratios around 60:40 or 70:30.


Thick Cloud Production 

E-liquids with a higher ratio of VG will deliver those thick, big clouds that you’ve been striving for. You’ll want to look for e-liquids with PG:VG ratios of 30:70 or 20:80. 

Important to note, these e-liquids do not suit all types of vape devices as they are more tailored to sub ohm kits. 

Discreet Vaping 

A 50:50 PG:VG ratio is perfect for those looking to be discreet with their vaping without losing flavour or vapour production. Not everyone wants to be blowing out plumes of vapour when they walk around so this is the perfect option for someone who wants less vapour production, and a cigarette-like feel when vaping.

If you’re looking for a specific criteria for your e-liquid blend, you could always delve into the world of mixing your own e-liquid ingredients to tailor it to your needs.
