The two main components that make up the vaping experience are the device which is used for vaping and secondly the e-liquid that is vaped.
In this guide we will be looking at the e-liquid in a bit more detail. We often find that customers are sometimes unsure of the type of e-liquid they require. The aim of this guide is to try and make it easier for you, the customer, to decide as to which type of e-liquid is going to solve the problem of nicotine and flavour delivery.
What makes up the e-liquid?
The two main ingredients of e-liquid are VG, Vegetable Glycerine and PG, Propylene Glycol. These two ingredients are widely used in the food and medicine industries. In e-liquid manufacture the VG serves as a thickener and the PG is used as a carrier to carry the flavouring and the nicotine.
All e-liquids regardless of flavour or brand carry a mixture of VG and PG. The mixture of VG and PG Is written down as a percentage, together this equals to 100% of the total liquid. For example the most common mixtures of VG and PG we are as follows 50% VG 50% PG, 70% VG 30% PG, 60% VG and 40% PG. E-liquids sold in the UK have to follow strict guidelines imposed by the MHRA which is the Medicines and Healthcare Regulatory Agency. The role of the MHRA to is enforce laws set up in the Tobacco Products Directive TPD which is a larger EU directive set up to moderate vape products. The TPD came into force on the 20th of May 2016 and states that all e-liquid must have full toxicology and emission reports published before it can reach the market. The main consequence of the TPD for the EU vaping industry was the restriction in volume of nicotine containing e-liquids to 10ml. This gave birth to the short-fill market. A short-fill is primarily a bottle of non-nicotine containing e-liquid ranging from 30ml to usually 120ml that has one or more 10ml 18mg “shots” of nicotine added to it to produce the overall desired, e-liquid nicotine, strength.
So what else is in e-liquid?
An e-liquid will usually contain nicotine in addition to the flavouring, VG and PG. The nicotine is the addictive chemical that is found in the tobacco, in conventional cigarettes. Cigarettes are basically a nicotine delivery device. It is the addiction of nicotine that causes what we know as cravings. Therefore, the role of the e-liquid and the vaping device is to deliver nicotine to the body. However this is a much less harmful way of getting a nicotine into the body as vaping contains no tar and it does not contain carcinogens. This was one of the main reasons why Public Health England (PHE) found that vaping e-liquid on the whole is 95% less harmful than cigarettes. https://www.gov.uk/government/publications/e-cigarettes-an-evidence-update
A table to show what type of Vape Kit and E-Liquid combination to use.
|Type of Vape Kit||Coil Resistance/Ohm||Type of E-liquid|
|MTL= Mouth To Lung||⇧ than 1||0-60% VG|
|DTL=Direct To Lung||⇩ than 1=Sub Ohm||60%-100%|
What flavour of e-liquid should I go for?
It is best to choose a flavour that you are going to feel comfortable vaping all day. The most popular flavours in the UK seem to be tobacco, menthol and strawberry. At Vape Charmer the most popular flavour of E-Liquid is Heisenberg. The Heisenberg flavour profile is a perfect mix of berries, blue raspberry and grape as you inhale, with a cool and icy sweet menthol on the exhale. There are many weird and wonderful flavours available to vapers, although it is best to start off with something simple and progress onto something a bit more adventurous as your taste buds start to come back to life. It is often said that the best way to stay off tobacco is to avoid tobacco type e-liquid flavours. You can be the judge of that one!
What nicotine strength of e-liquid should I go for?

What is the difference between Freebase nicotine e-liquid and Salt nicotine e-liquid?
Regular e-liquids contain freebase nicotine, which delivers a noticeable throat hit. Freebase nicotine is pretty much free to float around in the e-liquid, hence the name. The throat hit is sought after by heavy smokers. However, salt nicotine e-liquid does not give the vaper a typical throat hit. This is because conventional e-liquids have a higher pH value (more alkaline) than salt nicotine liquids so that is why they produce more of a throat hit. One of the advantages of using salt nicotine e-liquid is that the nicotine enters the bloodstream a lot quicker which is similar to smoking a conventional cigarette without the harshness on the throat. Salt nicotine is bonded or stuck to a salt molecule, this gives it a quicker path into the bloodstream. Which in turn leads to a quicker satisfaction of the nicotine craving.
Salt nicotine liquids give a faster absorption of nicotine into the body with a more noticeable hit which satisfies the nicotine cravings for longer. Juul were the first company to produce salt nicotine blends in 2015, this has led to a huge growth in popularity amongst vapers. Almost all of the e-liquid producers now have a salt nicotine range. Salt nicotine e-liquids are best suited to a MTL or Pod device.
