What Is In E-Liquid Vapour?
Within the e-liquid which produces the vapour for your device are the following ingredients: vegetable glycerin, propylene glycol, flavourings and nicotine, depending on the juice.
Vegetable glycerin is the main ingredient in eliquid; it is derived from vegetable oil, typically palm, coconut or soy. It is a sweet thick liquid which makes it great at producing huge clouds, although because of its thickness, a lower resistance coil is best suited if your juice has a higher ratio compared to pg.
Propylene glycol is another main ingredient you'll find in e-liquid. PG is a colourless, low viscosity liquid. It is an extremely good carrier of nicotine and flavouring. It produces a smaller cloud but can deliver much better nicotine hit with a more intense flavour.
The flavourings used in vapes are what make the liquid taste like the many varieties of flavours available in juices. They're a food-grade ingredient which is suspended in PG.
Nicotine concentrate is used within e-liquid to create the strength of nicotine required. Nicotine comes mixed in PG and is only available to purchase at a max of 20mg.
All the ingredients above are what create e-liquid and can come in several different ratios depending on the desired effect of the juice.
What Is In The Juice Of An E-cig?
Inside an e-cig or a disposable, you will usually find a nic-salt e-liquid containing a mix of propylene glycol, vegetable glycerine nicotine and flavourings.
Nicotine salt e-liquid is commonly used in e-cigarettes and disposable vapes because it is the best option for those looking for aid to help them quit smoking.
Nic-salt offers a 50/50 VG PG ratio and comes in a nicotine strength of up to 20mg. It carries a very similar feeling to cigarette smoke when the vapour is inhaled, making it a great follow-on device.
What Is Liquid E Used For?
E-liquid is used in a vape; it is heated by the coil to be vapourised into an aerosol, which is then inhaled.
The coil within your vape device is one of the most vital components. It is responsible for heating your e-liquid and creating the vapour.
There is a wicking material, usually cotton, which works by absorbing the e-liquid, which is then heated by the coil and thus expelling a vapour really for inhale.
For different ratios of e-liquid, you will need different coils;
You will need a lower residence coil for a high VG percentage, and the liquid is much thicker. Because VG is thicker, you can expect a much larger cloud if you're using a higher VG ratio than PG.
The higher the PG percentage, such as 50/50 VG PG, you will need a higher residence coil. The liquid is much thinner than the VG, so it will not require as much heat to create vapour production. You can expect to experience a much smaller cloud with he higher percentage of PG used.
