If you’re new to the vaping scene, you’re probably hearing a lot of terms that are very unfamiliar. Two terms that might have you scratching your head are the terms PG and VG. The two terms are thrown around a lot and you’re probably wondering just exactly what the terms actually mean and if there’s a reason to choose one over the other or if it’s entirely inconsequential.
Common Ingredients in e-Liquid
First, even the novices know that you can’t really use an electronic cigarette without any E-Liquid and E-Liquids are normally composed of four ingredients: nicotine, the flavoring, PG, VG, or a combination of the two, and sometimes distilled water if needed. PG is an abbreviation for propylene glycol while VG is an abbreviation for vegetable glycerin. There are other ingredients in e-Liquids, but propylene glycol and vegetable glycerin are the common bases found in all e-Liquids.
Moderation is the Key
Both propylene glycol and vegetable glycerin are generally regarded as safe. In fact, they’re found in a lot of the food consumed on a regular basis. They’re also found in a lot of medication, cosmetics, and even toothpaste. Although some users have complained about propylene glycol (PG) causing mild throat and skin aggravation. If a user is experiencing these symptoms, it is recommended that they lower the amount of PG in the E-Liquids being vaped.
Vegetable Glycerin (VG)
It’s often recommended that users not use more than thirty percent vegetable glycerin E-Liquid when vaping. The reason for this is consistency which can be quite viscous. Vegetable glycerin is rather thick which can lead to coagulation in a device. Also, due to its sweetness, vegetable glycerin-based E-Liquid can affect the flavor. While the vegetable glycerin typically produces a thicker, fuller vapor, it also has a tendency to minimalize the throat hit. Too much vegetable glyercin can cause a dry mouth, thirst, and sore throat.
Vegetable glycerin is also used more often for liquids that want to give out thicker vapor. When people use “diy” techniques to make their own e-juices. There are a lot of events which compares vapor viscosity and vapers who participate call it cloud chasing. They will often stand back to back like a duel, inhale and exhale the e-liquid. The following are everyday items that consist of vegetable glycerin:
- Make-up, shampoo, deodorant, and other similar beauty products.
- Desserts and baked foods.
- Pet food.
- Eye and ear products.
Propylene glycol (PG)
Propylene glycol is quite a bit thinner than vegetable glycerin which makes it the optimal base for mixing. The dilute does however produce a lot less vapor than its counterpart. Due to its more aqueous nature, propylene glycol-based e-Liquid exposes users to more nicotine so precaution it strongly recommended when handling it since nicotine can be absorbed into the skin. High amounts of nicotine can be poisonous. Since propylene glycol-based e-Liquid delivers more nicotine to the user and the liquid itself has less viscosity than vegetable glycerin-based e-Liquid. PG is recommended as the dominant base for any vaping mixture.
Individual Mixture of Your Liquid
There is a lot of debate about how just much VG or PG should be used in a mixture for the greatest vaping results. There has even been scientific research conducted which stated that the best mixture for vaping is thirty percent vegetable glycerin and seventy percent propylene glycol. In the end, it’s going to come down to the user. Some people are going to want less VG and some will want more for thicker vapor while others are going to alter the PG in their mixture for better throat hit and more vapor. However, it is generally recommended that users use the 30/70 mixture as a rule making changes for personal preferences as they see fit.
