Most e-liquid companies will use some sort of mix between vegetable glycerin (VG) and propylene glycol (PG). Each of these bases has their own benefits and drawbacks, but there are certain advantages to using only VG.
No Need for Sweeteners
VG already has a slightly sweet taste to it. It makes fruit liquids taste sweeter and dessert juices taste a bit more delectable.
Many times, in a PG base, the manufacturers will add some sorbitol or other artificial sweetener to make the juice more palatable. But these can contain manmade chemicals that, while approved by the FDA for human consumption, are not completely understood. There may be side effects to them that have yet to be discovered because we simply do not fully understand all the ways in which they interact with our bodies.
The best part of vaping an e-liquid is the hit you get from the nicotine and the flavor hitting the back of your throat. This leaves a wonderful sensation in your mouth and throat, and it differs due to the base you are using. With a PG base, you get a thin vapor that doesn’t remain in the air as long, so it can dissipate quickly in your throat, offering you only a slight hit.
But with a VG base, you get a nice, thick vapor and it is often full of flavor that lingers. The entire reason VG is added to a PG base is for its thicker, milkier vapor. Without it, the liquid tastes too flat and thin. So with a full VG base, you get a much more satisfying hit and a thicker vapor. It isn’t diluted or held back by other ingredients.
Easier on the Body
Another reason that the two vapors are often mixed is because of the frequency with which PG causes allergic reactions. When it is diluted with VG, it is not as likely to cause those problems.
So once again, a complete VG base wins out. If you don’t have any PG in your base, then you are far less likely to experience any allergic reactions. You can breathe easier and not suffer an irritated throat. Very few people ever have an allergic reaction to VG, so if you are sensitive to such interactions, it is a good idea to opt for a VG base entirely.
Those who have allergies of any kind, who cannot eat certain foods, who suffer from asthma and other breathing difficulties should all avoid PG bases when possible. And there are e-liquid companies that offer fully VG bases for their products. If you want something that is all natural and won’t give you any allergic reaction, then this is definitely the way to go.
Ultimately, you will have to experience the bases for yourself to see which offers you the more satisfactory experience. People often come away with different preferences, but if you want a healthy vapor, there is not a better option than a VG base.
