This blog is based on my own experiences and is written as my own personal opinion and should be taken as that only. Please remember to follow and observe all safety precautions.
nicotine composition as it pertains to VG, PG and flavoring and how they react with each other as it relates to taste.
You first have to understand that the VG and PG solutions are carriers for nicotine. The nicotine will not change it's chemical composition regardless of what carrier it's put in. The nicotine will still be nicotine so it does not matter what nicotine solution you start with if your end result is going to be a 50/50 base. You will still have equal parts of PG and VG and the nicotine chemical composition will not change.
It starts making a difference in taste when you move away from the 50/50 ratio because VG has a natural sweetness and it is thicker. So if your mix is lets say 80VG and 20PG the mix will be thicker and sweeter but the nicotine chemical composition will be the same and unaffected. It also does not affect nicotine strength. If you mixed it down to 12mg it will be 12mg regardless whether the predominant carrier is PG or VG.
How flavoring effects VG/PG composition
How flavoring effects VG/PG composition is a different story. Flavoring as far as I know will not affect nicotine composition but in a way does affect pg/vg composition. Not so much in the steeped finished product but in freshly mixed product you sill notice a difference. As VG is thicker it takes longer for the flavor molecules to move through and blend or bond with the molecules of the vg solution thus the final taste is slower to arrive then if the mixture was PG. You also have to realize that PG is a better desolving agent then VG so the solid flavoring molecules will quickly disperse through the solution. Further you also have to consider the added sweetness when flavoring a high VG mix. But the final taste result after it is steeped will be the same. So I don't really agree with most that say higher VG mixes need more flavor then higher PG mixes. I believe the mix just needs more time to mature.
It also should be noted when formulating a base that there are other factors that will also influence the final mix such as what the flavoring base carrier liquid is (PG/VG or alcohol). The additional PG/VG or alcohol contained in the flavoring itself is additive to the base and needs to be taken into concideration when formulating the base.
