What’s Really In E-Liquid?
E-Liquid is key in the electronic cigarette world as the juice that fuels the modern and healthier alternative to old school tobacco cigarettes. Once the e-juice has been heated, a vaporised mist is created which is then inhaled just like the smoke from the conventional cigarettes – but what exactly is this e-liquid made from?
The main base ingredient of e-liquid is Propylene Glycol. This organic compound has no colour and hardly any odour and is a clear liquid with a high viscosity. As the Propylene Glycol is a relatively thin liquid it helps to prolong the life of the cartridge. It is also renowned for creating that strong hit to the throat and is responsible for producing the vapour. Propylene Glycol can be commonly found away from electronic cigarettes – not only is it used as a food additive in thousands of products consumed on a daily basis, it is also present in many personal care and skin care products. Another example of its use is with the smoke machines used in theatres! Therefore this compound is considered a safe one and is FDA approved.
Often Vegetable Glycerine is also used as a base ingredient for e-liquid, or e-juice as it’s also commonly known. This is considered to be one hundred percent safe as it is derived from vegetable plant oils and is a great substitute for those with allergies. Vegetable Glycerine has thicker properties than Propylene Glycol, which results in greater vapour levels, but not such a good hit to the throat and some companies use a combination of the two perhaps in a ratio of 60 to 40.
Nicotine is also present in most e-juice. This is a stimulant that is highly addictive but importantly is not responsible for causing cancer. Depending on the company, the e-juice will contain a certain strength of nicotine commonly described as so many milligrams per millilitre. Most companies offer various ranges of strengths including a nicotine-free option enabling the user to gradually reduce their intake.
Finally that then leaves the flavour usually made up of naturally occurring or FDA approved additives. Common flavours include tobaccos, menthols and fruits. A lot of companies ensure all of their batches are independently tested such as V2 Cigs for whom the health aspect of vaping is a very important one and who ensure that their batch testing results are fully traceable.
