Yep, they are not paying these scientists *not* to find things. "Doing a good job" pretty much by definition means finding more "dangerous" ingredients.
David is right : Perfumers will work with whatever they have, so they will always have work. But at the same time, I rarely hear rave reviews of frags that have been reformulated, so it's hard not to see these restrictions as having a negative impact on what's possible.
The part about even recent releases needing to be reformulated is something I think all aficionados are distressed by though. A person likes to think they have an understanding of things, but these days when I read back over the reviews in the directory, I have no idea what kind of faith I can put in them. Which of any number of iterations is the reviewer talking about ? The "real" stuff, or the "shadow of it's former self" stuff ? There is no way to really tell. And to think that this is only going to be a continuing problem, even with frags we think of as new on the market ?
When members of a groups can't trust that they are all talking about the same thing, those sorts of uncertainties don't provide much of a foundation for a hobby I'm afraid. Just look at all the anguish the Creed-heads go through. I can't imagine it's fun for them.
Of course the public just buys what's there at the counter, so perhaps it won't make much of an impact on sales as far as the manufacturers are concerned, but it sews distrust and uncertainty, and puts the hobby on a shaky footing I think. Particularly for those who may be new to it.
