Many of us enjoy e-liquids on a regular basis, but a lot of people don’t actually know what goes into them. In this post we will help you understand what your favourite juices contain.
Propylene Glycol (PG)
This colourless, organic compound is one of the base ingredients in e-liquid and it provides the throat hit when vaped. It is thinner than vegetable glycerin (VG), meaning that it leaves less build-up on coils and can be absorbed by the wick of the e-cig much faster. As well as this, PG has no smell or taste, meaning it won’t have an effect on any flavours used. PG also has many uses other than just e-liquids. It is used in many food items such as ice-cream, soft drinks and coffee based drinks and is also used in smoke machines to produce the fog. Propylene Glycol can make up anywhere from 10 – 70% of an e-liquid depending on whether it is mixed with Vegetable Glycerin or not.
Vegetable Glycerin (VG)
When people ask, “what is in e-liquid?” this is one of the main answers. Along with PG, VG is a main base ingredient in e-liquids. Made with vegetable plant oils, VG provides more vapour than PG as it is a lot thicker. However it doesn’t provide as much of a throat hit as PG does. Vegetable glycerin already has a taste, meaning it could affect flavourings in an e-liquid. The viscosity of VG means it will leave quite a bit of build up on the coils and insides of your e-cigarette and will take more power to vape. Most e-liquids use both PG and VG; different mixes will create different experiences for the vaper.
Nicotine, which is exists naturally in tomatoes, peppers and potatoes as well as tobacco, is used in most e-liquids. There are many different nicotine strengths available when it comes to e-liquids, including nicotine free options. This gives vapers freedom to choose what level is right for them. Nicotine content of e-liquids can be anywhere from 0 – 2.4%.
E-cigarette manufacturers use food-grade flavourings that are the same as ones used in food production. E-Liquids can be anywhere from 15 – 25% flavourings.
Distilled water is used to dilute the mixture slightly if needed. Anywhere from 0 – 12% of an e-liquid may be water.
