100% PG is used for DIY e-juice when you mix your own e-juice, see the 'DIY?' tab for more info on DIY e-juice. Remember that this is 100% PG and need to be mixed with both 100% VG and flavor essences. If you want a pre mixed product we recomend you look for Chemnovatic - VPG which consist of PG/VG: 70/30%.

100% PG is colorless, almost odorless, low viscosity and density. It does not contain demineralized water that reduces nicotine quality by delivering oxygen. The fact that it is oxygen-free provides the extended durability and keeps the color for a long period of time.

Each bottle also contains a QR code that takes you to Chemnovatics site where you can access tests, certificates and more technical specifications (also linked below).
