This is a great thread. I wish I found it sooner, and not so late in the evening. My mixes are a little bland also and I have been disappointed with them but still vaping them none the less. I added a little distilled water to a small batch I made earlier in the week and had hoped the H2O would spring the flavor to life but is hasn't done much at all. May be a little easier to vape but not as flavorful as I hoped.
The saline additive is an interesting thought. I looked at some local stores online and I was wondering if there is a concern using the contact or nasal saline solutions? There is a bunch of other additives in these I don't want to vape if they are an issue and I don't want to be my own guinea pig. In the mean time I will check out the local pharmacy for what they have on hand.
At the beginning of the thread there was posts about additives like Acetyl Pyrazine so I went looking for more info on this additive and found the blending kit at The Flavor Apprentice -
Perfumers Apprentice - Tobacco Blending Kit. It lists all the additive plus some others that were in an early posting.
Molecules in set: Acetyl Pyrazine, Carvone, Cinnamic Aldehyde, Damascone Beta, Ethyl Acetate, Ethyl Maltol, Ethyl Vanillin, Lialool, Menthol, Menthyl Acetate, Methyl Cyclopentenolone, Syringol, Tabanon, Tetramethyl Pyrazine, Trimethyl Pyrazine, Vanillin.
It's a nice kit if you want to invest in the kit as a whole.
