One of the 1st questions/concerns that my wife had when I started vaping was what I was breathing in. I didn’t know much about the eJuice other than it had nicotene, PG and/or VG, and that it had to be much better than inhaling the 1000’s of toxins and chemicals that I was inhaling as a smoker.
So what is in eJuice?
Most of the time, e-liquid is made up of primarily propylene glycol (PG) or vegetable glycerin (VG). Most e-liquids are made of entirely PG and are the most desired and some are made with a combination of PG and VG depending on the consistency desired. PG and VG are the base of most e-liquids and they are flavored with various food grade flavorings. Nicotene is added to most e-liquids and are mixed at various levels, measured in mg. Most full flavor e-liquids are 18mg to 24mg in strength.
Here are the ingredients found in most commercially available e-liquids or e-Juices.
Nicotine – The amount of nicotene in most e-juice is 0%-2.4% depending on the strength. Most major of e-juice makers use a pharmaceutical grade pure nicotine. The nicotine content in e-liquid is measured by the number of milligrams of nicotine per milliliter of liquid.
- VG (Vegetable Glycerin) – Vegetable glycerin, or glycerol, is a clear, odorless liquid produced from plant oils, typically palm oil, soy, or coconut oil. Palm and coconut oils are natural triglyceride mixtures; each triglyceride is composed of three fatty acids esterified with glycerin. Vegetable glycerin has a number of valuable applications that include cosmetic products, foods, and as a replacement for alcohol in herbal and botanical tinctures. VG is one of two types of base that makes up a large percentage of most e-liquids. It can be the entire base or can be mixed with PG. (Source)
- PG (Propylene Glycol) – Propylene Glycol, also known as PG is a viscous (thicker than water), clear and colourless liquid. It is considered odourless and tasteless. Propylene Glycol is a synthetic liquid so it is not extracted from natural recources. It is man made. Propylene Glycol is used in many applications accross many industries from foods to healthcare. Propylene Glycol is typically used as a base ingredient in E-liquid. This is the main ingredient (along with or instead of Vegetable Glycerin) that creates a vapour when heated. You will often find it used in products which are best kept moist as it help to stop products from drying out. (Source)
- Flavoring – Natural flavor from concentrates are used to give e-liquids the various flavors we enjoy. These flavorings are normally flavorings that are used in food and candy. It’s not known if vaporizing these flavors is good or bad for you officially, they are safe to consume in the foods we eat though.
That’s pretty much it. They are quite simple really.
