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