In what cases do you not use musks, iso e super, and/or hedione as 40%, 50%, or more of your formula? Or rather, how do you decide how much of these low-slope materials to use? The amount doesn't seem to change the fragrance much. Just the fact that they're in there at around at least 5% seems to make the difference. Is it just a way to make fragrances more difficult to decipher through GCMS by diluting the main fragrance with fillers that hardly do anything? This is the only thing i can think of. But mainly, im just interested in how y'all decide exactly how much you want to use for a fragrance. And if you ever don't use them in a fragrance and why.
