A question for the chemists, please.
What comments could you make about the following three 100% VG unflavored 36mg liquids:
1. A clear liquid, faint 'wet dog' smell.
2. An almost clear liquid with the faintest pale yellow tinge, strong 'wet dog' smell.
3. A pinky-red liquid, faint smell as above.
I'm just interested in why three liquids can look and smell so different when in theory they are the same thing. Seem to remember that the no-smell liquid has maybe had citric acid added to remove the smell. What are the implications of that? And the red color is remaining reaction compounds from the extraction process. Again, what implications does this have?
Sorry, but I haven't tested them for nic strength. They seem about right.
