Thanks for your thoughts. Your statement above gets more at what I'm thinking about. But it
isn't all flavoring right? It's flavoring dispersed into a PG or VG base, right? So it seems to me that just like our recipes have a total flavoring-to-base ratio, each individual flavoring has its own flavoring-to base ratio (possibly the reason for weak vs strong flavorings?), and this should also be considered when thinking about minimizing flavorings in recipes.
Or I could just stop thinking about this
But it isn't all flavoring right?
- In "pure" form, most flavoring is either in a gel-like form or crystallized (if you'll see some notes from TFA/TPA - you'll see that they state some flavors may crystallize and need heating/shaking to recombine them). More often than not, they're in crystal form, similar to how Ethyl Malitol if it's not mixed with a solution, and they're mixed with PG, PG & VG, Alcohol, Water or a mix of all four solutions to develop a product that's usable.

I'm sure that would be the case since all flavoring is composed of different chemical structures, just as most fruits are. That doesn't mean they're all safe, but if we take TPA/TFA and soon, Capella's, as examples, they're identifying which flavors have the chemicals that are deemed unsuitable for vaping or, at the very least, chemicals that some prefer not to vape (such as Acetoin and Acetyl Proprionyl which is what gives custards their buttery flavor). There's no set X to PG, VG, Alcohol, Water ratio that we'll be able to identify. Such ratios are what comprise the flavor and such ratios probably will not be divulged.
That all being said, some flavors are simply going to be weaker than others. If we took caramel and espresso and compared them, I'd expect espresso to be much stronger, so usage would be less to achieve the same level of flavoring as 2-10x that of caramel. The same could be said of a true espresso flavor versus a standard coffee flavor due to the way espresso is made.
Much like how the usage rates vary, I'm sure Company X's dilution rates vary and giving up how much of Flavor X is mixed in with their diluted product isn't something many will venture to divulge.
