Flavour, VG, PG, distilled water or vodka and diluted nicotine are the five basic ingredients of e-liquid. Whilst you can take the vodka and nicotine out of the equation—these two are dependent on the user’s likings—at the minimum, the juice can be made of VG/PG as the base and flavouring.
- VG or Vegetable Glycerol
A natural liquid that is derived from extracts of vegetables, it is thicker and has a minor hint of sweetness. This can somehow impact the taste of the juice, either in a bad or good way. This is an approved FDA product that is being used as well on food and even cosmetics.
- PG or Propylene Glycol
This is the most preferred base by DIYers due to the fact that it is tasteless. Unlike VG, it will not give any changes in the taste of the juice. It is federally approved, odourless, a colourless organic compound that is being used in many products like food, tobacco and a lot more.
PG is also present in different medicinal products that can be injected into the bloodstream, inhaled, used topically or orally. Most DIYers choose both VG and PG, as they have different characteristics to share on the e liquid.
- Vodka or Distilled Water
This is best used to thin out VG by 100%. It is not a critical ingredient but is still highly advised to be included in your e liquid. Vodka, on the other hand, is more preferred by people who want an added throat hit without the need of adding nicotine.
Flavouring comes in wide variety of options. The usual portion is around 10% to 20% flavouring but can be adjusted according to your liking. Before mixing the flavour you choose, make sure you read the label carefully regarding the right usage.
- Nicotine Liquid
This is available in different levels of strengths and can either be VG or PG base. If you can play around with the flavours, the same goes with the nicotine level.
On the other hand, to make your life a lot easier, you can always order e liquid online. You can let them do the mixing for you (the level of nicotine and the flavour of your choice) and wait for it to get delivered right to your doorstep.
