Why PG and VG in liquid e juice

1. Why PG and VG in liquid e juice

2. VG (Vegetable Glycerin) vs. PG (Propylene Glycol) When it comes to e-juice, two terms constantly crop up: VG and PG. Typical e-juice or e-liquid contains four ingredients. These ingredients are- Propylene Glycol (PG) or Vegetable Glycerin (VG), water, flavoring, and nicotine The presentation will give a brief understanding about both.

3. What are PG and VG? PG and VG are the odorless liquids that are combined with flavor and nicotine to create e-juice. Both PG and VG technically belong to the alcohol chemical class (despite the name, they are not intoxicating). They are deemed sugar alcohols and are included in many consumable products. They produce vapor when heated, which allow them to be inhaled. PG and VG are not oils, and can’t cause any of the medical issues — like lipoid pneumonia — that inhaling actual oils can. The two fluids have a different consistency to each other and a slightly different taste. They have distinct mouth and throat sensations when vaped. Most modern e-liquid uses a combination of the two fluids, though the ratio can vary dramatically.

4. Propylene Glycol (PG) E-juice It is less viscous than Vegetable Glycerin and easier to handle when (re)filling your atomizer, cartomizer, or clearomizer. Propylene Glycol (PG) has low density which means you will get less gunk when compared to Vegetable Glycerin (VG). It is absorbed much faster by wick material and polyfill fabric, which means that you can start vaping faster. Since Propylene Glycol is tasteless and odorless there is little or no flavor distortion.

5. Vegetable Glycerin (VG) E-juice Vegetable Glycerin (VG) is less popular when compared to Propylene Glycol (PG) base. It has much higher viscosity, which makes it a perfect base for vapers who love a thicker and higher density vapor cloud. It is easier on your throat which means it delivers less throat hit.  higher viscosity of Vegetable Glycerin (VG) typically requires more power and longer time to achieve optimal vaping temperature. Unlike PG base, Vegetable Glycerin contains preexistingflavor and sweetness. This means that in many cases the added flavoring will be diluted and final product (e-liquid) will be sweeter.

6. How to choose between PG and VG E-liquid? PG e-liquid tends to give you a better throat hit and a lot more flavor. VG e-liquid on the other hand, allows your atomizer to produce a lot more vapor. VG e-liquid is a thicker and more sticky fluid, and although most people do not show signs of allergy with VG, there are minority groups who complain about having phlegm buildup in their throats. The more VG e-liquid you use, the less of a throat hit you’re going to get – that’s the general idea. The vaping community is evenly divided when it comes to e-liquid preference. Some enjoy the intense throat hits more than flavor and vapor, others enjoy the sweet, thick plumes of vapor.

7. Can You mix PG and VG? 60 / 40 mix of VG and PG in your e-liquid can produce great vapor and more flavor. If you like, you can tend to use mix of both PG and VG in particular ratios, such as 70 VG / 30 PG. This is the optimum ratio for most each uses as it provides a nice throw hit, good flavor as well as tons of vapor production. Vegetable Glycerin (VG): more vapor, less throat hit. VG e-liquid is thick and a little sweet. It produces luscious clouds of vapor.  VG e-liquid also imparts a sweeter taste to your liquid. (VG eliquid is available in Tobacco and Mentholflavors). Propylene Glycol (PG): better throat hit and flavor. PG e-liquid is thinner and produces  more of a “throat hit” than VG e-liquid does, which simulates the feel of smoking better.  PG e-liquid also has a higher rate of sensitivity for some people, meaning that some people just can't use PG in their vape. Usually side effects are mild allergy symptoms.

8. What should I be aware of when vaping PG? Some people find a high level of PG irritating to the throat. If you find yourself coming out in a rash or suffering other unpleasant reactions after using PG-based e-fluid, you may have a more common mild sensitivity to PG, and should look at using high-VG juice instead. The most common side effects of using e-liquid containing propylene glycol are symptoms of dehydration, like dry mouth, sore throat, and increased thirst. It is advised to drink more water and liquids than usual for the first few weeks of using your e-cigarette. If hydrated properly, these symptoms usually last anywhere from a few days to a week as the body gets used to the propylene glycol.

9. What should I be aware of when using VG? The increased thickness of VG means it can reduce the life of atomizers quicker than PG-based juice. High VG liquids clog up coils more rapidly, and will not work well, if at all, in certain tanks. Older products are especially susceptible, particularly models that use smaller coils such as clearomizers. As with PG, the most common side effects of vaping high VG e-liquid are those of dehydration: dry mouth, sore throat, and increased thirst. Again, be sure to drink plenty of water and take a break from vaping if necessary.

10. Conclusion The basics of PG and VG are quite easy to grasp. They both work in different ways, and each has advantages and disadvantages. It is better to start with a 50-50 PG to VG ratio then try out various combinations and see which you prefer. Many vapers like to use different levels of PG and VG at different times, and with various devices and flavors. Tobaccos, fruits and beverage flavors often go well with PG. Similarly, flavors based on cream, custard and yogurt tend to work well with high VG. There are no fixed rules, just follow what your taste buds tell you!
