E-liquid or vape juice is the liquid vapers use to produce vapor or clouds and simulate the act of smoking cigarette. It is composed of 4 ingredients, PG or Propylene glycol, VG or Vegetable Glycerin, flavoring and nicotine. These four ingredients are the essential component of an e-liquid. Some manufacturers add distilled water to make the juice a little diluted if it is too viscous like most 100% Vegetable Glycerin based vape juice.
Propylene glycol vs Vegetable Glycerin
PG or Propylene glycol and VG or Vegetable Glycerin are the primary components of e-juice. All juice ingredients are FDA approved, so it is very safe to use. PG is a clear and colorless liquid that is usually used as a flavoring base for pastry products. VG is traditionally used in food production, cosmetics or vape juice. It is an organic compound made from vegetable oil. It is sweeter and more viscous compared to PG. There are different ratios of ingredients when making e-liquid, depending on the user’s preference. You can make a 100% VG or PG based juice or you can mix both components. But the question is, which is better, a VG or PG based vape juice?
If you based it on throat hit, PG based juices are far stronger compared to VG based. It also has more flavor and taste. Vapor production wise, vegetable glycerine produces more vapor than PG, and because VG is made from vegetable oil, it has a sweeter aftertaste. PG also has a longer shelf life because of its greater moisturizing properties. The e-liquid requires heat to produce vapor. The VG based liquid has a higher heat resistance compared to PG, that’s why it produces more vapor. The downside is, VG will create a burnt aftertaste if used in a high-powered mod
Because PG produces thinner vapor and has a lower density, it is absorbed faster by the cotton in your atomizer and produces less gunk compared to VG. It means that PG is a lot cleaner and atomizer friendly. VG produces more vapor, and due to its natural sweetness, it will stick to the cotton and coil, and produces gunk. It will be harder to remove the stain to the coil, and the atomizer will need more maintenance if VG based juices are used. It is best to use rebuildable atomizer like Trident or Omega.
Most juice lines mix PG and VG to get both of the ingredient’s advantages. While Vegetable glycerin gives the more vapor and sweetness, PG, on the other hand, will provide a throat hit and better taste. Most users prefer 70/30 VG to PG ratio. Vape juice with 50/50 and 60/40 mixture is more popular among people who join vaping tournaments since it produces a lot of vapor compared to 70/30 mix ratio.
For new vapers or recreational users (non-smokers), we suggest that they use e-liquid that don’t have nicotine because as we know, nicotine is very addictive. The number of milligrams per milliliter of nicotine in the liquid is used to measure its content level. For example, in a 12mg/ml nicotine content, there are 12 milligrams of nicotine for every one milliliter of base liquid. For former cigarette smokers, you can use a stronger e-liquid with a higher nicotine content. The best thing when using vape is you can increase or decrease your nicotine intake without increasing the amount of vape juice you are consuming. One more thing, the reason you are using an e-cigarette is that you want to quit smoking, so you need to use e-juice with lower nicotine content to help you completely stopped smoking.
Flavoring is one of the essential ingredients in e-liquid that provides the taste users want. You can buy it in vape shops or buy it online. There are websites like http://www.organicvapejuice.org that offers a wide variety of vape juice flavoring from pastry to fruity or mentholated. Most e-liquid uses 5-20% flavoring in their mix, except for tobacco flavored which uses 1-3%.
The best e-liquid
There’s no such thing as best vape juice. Every user has a different preference. Some people like VG based liquid because they want more vapor or PG based because they want a throat hit and better taste. Every user is different. If you are new in this scene, the best way to start is to choose a 70/30 mixture and adjust from there.
