Why is “PG” necessary in Vaping oils?
Teresa P pretty much nailed it on the head! For further explanation, we do have some really great blogs and whatnot pertaining to this. Here's a quote from one of our blogs that I think explains it pretty well, " PG is a thinner liquid, and the make up of PG allows for "introduced" products (such as flavors and nicotine) to remain suspended throughout the liquid while it is in a resting state. This is the primary reason for many E-Juices to have PG in their recipes. With an additive such as PG, the juice stays more homogeneous and as one mixture, rather than separating into the different compounds as it sits over time. The oxidation process (steeping) can only occur if the mixture remains a mixture, AKA if there is nothing to keep your flavor and nicotine from separating completely (PG/VG!) it won't steep properly." That really explains the science behind choosing PG in vape juice over other additives!
