All electronic cigarettes, whether using pre-filled cartomizers or a fluid tank system, require e-liquid to produce the inhaled vapor. The e-liquid is a simple solution that contains the following components:
Nicotine: The stimulant in cigarettes and the substance that is addictive in cigarettes is the nicotine. Nicotine is a relatively simple alkaloid, called pyridine. It is naturally formed in tobacco leaves and is released, along with all the related toxic products of combustion, when a cigarette is burned. The nicotine used in our e-liquid, is natural nicotine produced from tobacco leaves. It is produced by mechanically and chemically stripping the nicotine from the leaves and then under the most stringent control, distilled out of solution, using fractional distillation techniques, to produce the highest possible levels of purity.
Flavoring: Nicotine is produced from tobacco leaves, the distillation process produces extremely pure nicotine, which has no residual tobacco flavor. To provide an e-liquid that has a taste that resembles a normal cigarette, flavors must be reintroduced to the nicotine solution. Due to the development of the e-liquid industry there are an infinite number of flavors that can be added to make whatever flavor you desire. At The Vapor Stop USA we offer ranges of flavors manufactured here in the USA.
Diluents: The third ingredient of e-liquid is a diluent. The diluent essentially performs two functions. Firstly it is added to dilute the mixture of nicotine and flavors to the correct strength. Secondly it adds the part of the solution that produces the vapor that is inhaled and transports both the flavor and nicotine from the electronic cigarette to the user.
Propylene Glycol (PG): It is a colorless, nearly odourless, clear, viscous liquid with a faintly sweet taste. It is a common base solution used in a range of pharmaceutical products and a food additive often referred to as E1520.
Vegetable Glycerine (VG): Again Vegetable Glycerine, like Propylene Glycol, is a common food and pharmaceutical additive. It is used to provide similar functions of bulking, diluting and stabilising a range of common products. It is often referred to as E422.
The strength of e-liquid is essentially how much nicotine the fluid contains in a set volume of e-liquid. Most use a basic measure of milli-gram of nicotine per milli-litre of total fluid volume (mg/ml).
This is how the solutions it offers denote the amount of nicotine they contain. This notation was defined to compare directly e-liquid to conventional cigarettes. For example, if a cigarette package states that there is 1.8mg of nicotine in the product, it means that each cigarette contains 1.8mg of nicotine. Therefore in a pack of 20 cigarettes there is a total of 36mg of nicotine.
In comparison, an e-liquid of 18mg/ml strength denotes that there is 18mg of nicotine in each milli-litre of fluid. Therefore if you were to vape 1ml of this fluid then it would contain the same amount of nicotine as in 10 1.8mg conventional cigarettes.
More experienced users are now often referring to the percentage of nicotine in the solution. For example, each 1mg/ml of e-liquid contains by volume 0.1% nicotine i.e. 99.9 parts are diluent and flavoring mixture and only 0.1 parts of the fluid is nicotine. Using this notation, an 18mg/ml e-liquid contains 1.8% nicotine.
