The E Liquid For Vapes also named as e-juice is the liquid you put in an electronic cigarette to produce vapor and imitate smoking. It is basically composed of up to 4 kinds of ingredients normally; PG or propylene glycol, VG or vegetable glycerin, and the nicotine which you can choose from 0mg up to the higher level. However, you can also possibly add some distilled water to mitigate the e-liquid if you think it is too thick for you, just like 100% VG based e-juice.
All about the VG vs PG
The VG or Vegetable Glycerin and the PG or Propylene Glycerin are the two main ingredients based on e-liquid. They are equally safe and of course, both are FDA or Food and Drug Administration approved. The VG is an essential organic liquid based on organic oil. It is thick and sweet which is gummier than PG. The preeminent applications of Vegetable Glycerin are for e-juices, food production, and cosmetics products. The PG is a colorless and clear liquid which typically has been used in food products as the flavoring carrier. The principal applications of vegetable glycerin are food production, cosmetics products, and e-juice. The VG is thicker while the PG is thinner. A-liquid can be made of 100% VG base or 100% PG base or it can also be a combination of these both.
Analyzing which one is better between VG vs PG
You need know its differences when looking forward to its categories. From there, you seem to know which one among them is better. You can determine its character by initializing the throat hit it gives. PG based e-juice gives you a stronger throat hit and higher natural flavor taste compared to the VG based ones. About the production of its vapor, this VG based e-liquid produces vapor more than this PG based ones. It also gives you a little sweet aftertaste. When speaking about its storage time, well, these VG based ones have the shorter time because of its powerful moisturizing properties. The PG based e-juice has the longer time to store.
Temperature Opposition and Atomizer Friendliness
The VG based e-juice has the higher temperature opposition compared to the PG based ones. Therefore, with VG based e-juice, higher power is needed to be able to produce better vapor. However, if using high power with the PG based e-juice, it might give you some burnt tastes after all. Propylene Glycerin has low density because it is thinner and can be consumed much quicker by wick materials. It means that you will probably get fewer gunks and start vaping faster compared to Vegetable Glycerin. VG can produce thicker clouds because it is thicker and actually has high density. Furthermore, it is also more likely to heat elements, build up your wicks and some other vaping ingredients that required you to do more cleaning and maintenance of your vape. Therefore, it is best to recommend you to use with the re-buildable atomizers. You also need to be aware that there is a small percentage of vapers have an allergy to PG, like having troubles with their stomach and some rashes.
