The Content of E-Liquid
What is an e-liquid? And what is it that makes all that vapor? The main ingredients found in e-liquid are propylene glycerol, vegetable glycerin, nicotine and flavoring which those two occupied about 8% to 10% of the total composition of e- juice.
Three of the four ingredients in e-liquid are food grade substances. However, the nicotine found in e- liquid is a pharmaceutical grade and extracted from tobacco plant. Therefore, electronic cigarettes is classified as a tobacco product by the FDA.
Vegetable glycerin is a very important ingredient in making vape juice because it produces a lot of vapor.The vapor produced by vegetable glycerin is nice and gentle compared to vapor produced by propylene glycerol. In addition, vegetable glycerin can make mass of clouds of vapor. The one weakness of vegetable glycerin is that it does not carry flavor as well. However, the vapor production is still wonderful.
