What Is in E-Liquid?


How many times have you been asked what’s in your e-cig? Chances are your first response isn’t “a delicate mix of propylene glycol, vegetable glycerin and distilled water”. The most common response is usually ‘strawberry cheesecake’, ‘menthol breeze or whatever flavour it is that your non-vaping friends have detected in the air.

As vapers, it is important to know exactly what is in e-liquid. It helps you understand why you’re choosing to vape and it helps inform your decisions when finding the right e-liquid for you.

Although not all e-liquids have the same ratio, this is the typical breakdown of ingredients in an average e-liquid.

At first glance these ingredients don’t really mean much to the average vaper, but when you break each one down and look at what they bring to the mix, you will start to see how they work together to create that delicious vape hit.

What is Propylene Glycol (PG)?

PG is a colourless, organic compound that serves as one of the base ingredients in your e-liquid, providing the throat hit when you vape. It’s thinner than vegetable glycerin and leaves less buildup on coils, absorbing into the wick much faster. PG has no smell or taste, so it doesn’t affect the flavour that’s used in the mix. Along with e-liquid, PG is also found in food items such as ice-cream, soft drinks and coffee based drinks, it’s also what produces the fog in smoke machines! In a bottle of e-liquid, PG can make up anywhere between 10% and 70% of your e-liquid ingredients, depending on whether our next ingredient is present or not…

What is Vegetable Glycerin (VG)?

Made with vegetable plant oils, VG is another base e-liquid ingredients, providing more vapour than PG as it has a much thicker consistency but less of a throat hit. Unlike the flavourless PG, VG has a sweet taste and is commonly used as a sweetener in sugar replacements. Due to the taste, the amount of VG used in an e-liquid could affect the flavour.

The viscosity of VG also means that it leaves a build up on the coil and takes extra power to vape. Most e-liquids use a balance of PG and VG, using different mixes to create different vaping experiences.

Nicotine

Nicotine is used in most e-liquids although there are different strengths that you can choose from to ensure you’re getting the level that’s right for you. Nicotine content can be anywhere from completely nicotine free to 2.4%.

Did you know? Nicotine is found naturally in tomatoes, peppers and potatoes.

Nicotine levels at LiQuid

We offer a range of nicotine strengths, making it easy for you to choose the right one for you. If you were a heavy smoker and looking to use vaping as a way to help you quit, a higher nicotine level is recommended. For lighter smokers we recommend the lowest strength, moving up if you need more of a ‘hit’.

Distilled Water

Distilled water is used to dilute the mixture slightly if needed. Anywhere from 0 – 12% of an e-liquid may be water.

Flavourings

E-cigarette manufacturers use food-grade flavourings that are the same as ones used in food production, an e-liquid can contain anything from 15 – 25% flavourings. Flavours range from classic tobacco and menthol, all the way up to the more adventurous flavours including choc-o-nana, pina colada and even strawberry milkshake.
