E-juice, also known as e-liquid or vape juice, is used in vaporizers and electronic cigarettes. It is made up of basic food grade ingredients and other ingredients like nicotine and flavouring that account for about 8% to 10% of the total composition of e-juice.
How does vape juice work?
Basically, an atomizer heats the liquid to the point that becomes vapor that you can inhale. This is the reason why smoking e-cigarettes is called vaping. It produces a cloud of vapor, and it has the subtle smell and taste of whatever flavour cartridge you buy, like tobacco, menthol, strawberry…
What is in a e-liquid?
Vape juice is made of water, aroma, propylene glycol (PG), vegetable glycerin base (VG) or/and nicotine. It is used in vaporizers and electronic cigarettes.
Propylene glycol, PG in the vaping community, is an organic substance that has been using for over a century. PG is found in everyday products from toothpaste to shampoo to medications. It has been deemed to be safe for human ingestion. The vaporized form of propylene glycol looks like smoke.
PG carries flavour very well, but it does absorb water. That means it has a dehydrating effect. As a result, some PG e-liquids can be harsh. This is the reason why most of e-liquids are largely balanced by vegetable glycerin, or VG.
Vegetable glycerin, also called VG, has been deemed safe for human consumption. There are different ways to get vegetable glycerin, but the main source used by vape companies, it is extracted from the palm plant. VG is a preservative and is used in many different types of foods. You will also find it in most lotions and cosmetics.
What makes VG such a good liquid for vape juice? It makes a lot of vapor, nice gentle cloud of vapor in comparison to PG. However, it does not carry flavour as well as PG, so both substances are necessary for a balanced e-liquid.
The nicotine used in e-cig liquid is pharmaceutical grade and extracted from tobacco plants. Nicotine is considered an addictive substance. E-liquid with nicotine is made for adult tobacco consumers only.
More recently, a new type of nicotine has emerged. Nicotine salt E-liquid is not extracted from tobacco leaves, rather it is extracted from the salts in the stems. The advantage of using a nicotine salt e-liquid is that you can vape a much higher nicotine content without experiencing harshness. Nicotine salt is smoother than regular pharmaceutical grade nicotine. The real advantage is that you can get a lot of punch and little bit of vapor. That’s why nicotine salts are often the preferred he liquid for smokers.
