Now I may have spent too much time around liars in my youth and lawyers in my adulthood, but that statement by Chanel completely skates on a pre-emptive reformulation. As in, "Thank God the reformulation went out in time, well before the new standards were issued, and nobody noticed." Not saying it's true - just saying it's possible.
Personally, I think the solution is for the industry to move to the sale of limited edition original formula stuff with fancy bottles and heavy warnings on shocking orange tied-on tags. The people who want the real McCoy are going to frankly drool at the orange tags hanging from the nice packaging, as in "OMG! REAL oakmoss! Original strength!" The perfumistas take off the tags, throw them in the garbage, and it's all over. Or keep the tag in the packaging for resale. The companies can sell the unlabeled stuff to everybody else. It's a win-win situation for everybody. What I'm thinking is something in between the absurdly priced corporate gifts in real crystal and the regular department store stuff.
The problem with IFRA is that is says everybody has to drink beer, not wine or whiskey. It's clearly ridiculous. There's no need to have a lowest common denominator.
