Will nicotine liquid remain clear for the life of the PG/VG?

  • Will nicotine liquid remain clear for the life of the PG/VG?

NO!  PG/VG containing nicotine will not remain clear for extended periods of time. This does not mean the liquid is no longer good, it is just normal oxidation. Nicotine oxidizes with oxygen. Even if stored with as little air in the bottle as possible, the PG and VG itself contain oxygen molecules. There has been many discussions on this topic in the forums as well as on the internet.

Here are some links to the threads on ECF forum that will shed a lot of light on this subject.

  1.  ECF thread by DVap, a Chemist, on Nicotine Purity and Storage!
  2.  ECF post by Kurt, also a Chemist, on color change in nicotine liquid
  3. Another ECF post by Kurt on Pink tint in nicotine liquid
  4. Yet another post by Kurt on high mg nicotine liquid changing color
