The term e-liquid/e-juice is common among vapers. Those new to vaping may find the two words confusing. An e-juice/e-liquid refers to the liquid that is used to produce vapor in an electronic cigarette. An e-juice is made up of four ingredients, and they include: Propylene Glycol (PG), Vegetable Glycerin (VG), food flavors, and nicotine (you can choose one with no nicotine). In this article, we are going to discuss the two primary types of ingredients found in e-juice and their differences in vapor production, throat hit, viscosity, and how to choose between the two.
Propylene Glycol (PG) vs. Vegetable Glycerin (VG)
PG and VG are the primary additives to an e-liquid. Both ingredients have been approved the U.S Food and Drug Administration as safe for human consumption. Below are the differences between the two components:
Difference #1 Physical Attributes
Propylene Glycol is tasteless and transparent in appearance. As a result, the flavor added presents very well in PG. Propylene Glycol is also thinner and has a lower viscosity than the Vegetable Glycerin. Due to its low viscosity, Propylene Glycol is less gunky than the Vegetable Glycerin. It does cause clogging. Its light consistency makes PG to be absorbed quickly through the polyfill material when cartomizers are used. As a result, the juice is allowed to reach the coil constantly.
The Vegetable Glycerin, on the other hand, is characterized by a natural sweet flavor that can be noticed when vaping e-juices. Compared to the PG, it is thick and has a high viscosity. Due to this, it can easily clog inside the coil inside the cartomizer. The thickness is advantageous because it is difficult for it to leak from the tank. However, one will need to clean the tank to prevent clogging from occurring regularly.
Difference #2: Difference in Vapor Production
Those vapers who love huge clouds of vapor should consider going for the Vegetable Glycerin. An e-liquid that consists of 100% VG produces a thick cloud that has a smooth feel. It provides you with an opportunity to perform some cool smoke tricks.
Propylene Glycol, on the other hand, is suitable for vapers who aren't interested in thick vapors. It gives vapers a chance to enjoy the combination of its clean state and light vapor. Propylene Glycol is best for those who like vaping in public and do not want to attract much attention from the public with thick vapor clouds.
Difference #3: Throat Hit
Propylene Glycol has a strong throat hit compared to its counterpart. Such vapers enjoy more powerful throat hits which resemble that found in the traditional cigarettes. However, individuals who do not find any joy in a stronger throat hit should consider looking for the Vegetable Glycerin. E-juices with 100% VG hardly produce any throat hit. They have a smooth feel when one is vaping.
Difference #4: Storage Time
The Propylene Glycol has a longer storage time than the e-juices with the Vegetable Glycerin ingredient due to the powerful moisturizing properties.
Difference #5: Tank Types
• Clearomizer: It is the most famous tank for vaping. The length of its coils ranges from 1.2 to 2.5 ohms. It is not advisable to use the vegetable glycerin in these tanks. Its coils cannot handle the thick ingredient correctly. A 50/50 PG/VG ratio is the most suitable for a clearomizer tank.
• RDA/Drippers: These will offer you more choices regarding the ratio between PG and VG. The ratio will be determined by the strength of the coil that is being utilized. A mixture with a high amount of VG will need sub-ohm coils. High-ohm coils are necessary for the e-juice with a high PG ratio. The most recommended ratio for drippers is 30% PG and 70% VG.
When it comes to choosing between Propylene Glycol and Vegetable Glycerin, several factors should be put into consideration. The choice you'll make will depend on your personal preferences.
