What E-Liquid is:
Electronic cigarettes do not burn tobacco or rolling paper. Instead, a battery inside the device powers the atomizer which in turn converts the liquid solution into vapor. This solution, often called e-liquid, is housed in a pre-filled fluid tank system or cartridge.
The e-liquid is heated by the atomizer to deliver the sensation, taste and gives the exact feel of smoking. You can have the most powerful e-cigarette battery but your vaping experience or pleasure to be precise will not be that enjoyable without some high quality e-liquid.
E-liquids vary from brand to brand but usually contain the same main three ingredients like nicotine, flavoring and the diluents.
Nicotine is basically tasteless. In order to replicate the flavor of cigarettes, e-liquids are mixed with an infinite number of flavoring compounds. Some e-liquid manufacturers offer up to 90 different flavors ranging from classic tobacco and menthol to food concentrates such as coffee, chocolate, fruits, candy and spices. You can find banana flavored juices in forms of like : Banana, Banana Cream, Banana Graham, Banana Nut Bread, Banana Pudding, Banana Split and so on.
Nicotine in E-Liquid
Of the thousands of chemicals in cigarettes, nicotine is probably the least lethal. It is an addictive substance though. Smokers often switch to e-cigs to quit the tobacco and other harmful toxins while continuing to get their nicotine fix. E-liquids contain varying levels of nicotine, often measured in mg/ml or simply ml. Double extra strength e-liquids can contain up to 72mg/ml of nicotine while ultra light fluids are often in the 6-8mg/ml range. For those who want to quit the nicotine altogether, manufacturers produce zero-nicotine e-liquids.
Diluents in E-Liquid
The liquid nicotine and flavorings won’t turn into vapor without the third most important ingredient in e-liquids – diluents. The diluent base works two ways: first, it is added to dilute the mixture of nicotine and flavors to the correct strength, and secondly, it is responsible for turning the liquid solution into inhalable vapor. E-cig manufacturers commonly use any combination of these three diluents:
Propylene Glycol (PG): Pharmaceutical-grade propylene glycol helps produce what we refer to as ‘throat hit’ in combination with nicotine and flavors
Vegetable Glycerine (VG): Glycerine helps produce more vapor.
Aqueous Glycerine (AG): Pharmaceutical-grade Aqueous Glycerine is diluted with de-ionised water.
E-liquid strength refers to the amount of nicotine fluid contained in a set volume of e-liquid, measured in milligram of nicotine per milliliter of total fluid volume (mg/ml). This unit of measurement was defined to compare e-liquids directly with 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 36 mg of nicotine.
