First, a little history about both products.
Propylene Glycol or short "PG", is also an organic compound used in a variety or commercial purposes. It is derived from petroleum resources and used as the base of many food flavorings. PG is colorless, odorless, and has a mild sweet taste. Is is used by the pharmaceutical industry in oral and topical applications. PG is approved by the Food and Drug Administration as "generally recognized as safe", or GRAS, product. In personal vaporizers uses, PG tends to be flavorless, allowing the flavor to really shine.
Vegetable Glycerin or short "VG", is a natural organic compound derived from vegetable fats. It is sweet, colorless, extremely viscous, usually used in food as a humectant or solvent.
In personal vaporizers uses, VG created a very thick vapor. VG produces more vapor than PG, and sometimes can mask over certain flavors. We add extra flavor to our 100% VG juices for this matter.
After all that being said, it comes down to personal choice. If you are not allergic or you don't have any reactions to PG, you can choose any product from our BasicPotion line.
Our recommendation is to always try our Exclusive OrganaTine line of products first and then move to a PG/VG mix.
