As for what you're talking about, INO, that's a part of marketing one-brand-over-others pushy kind of promotion and all about marketing wars. Like stuff about atypical pneumonia, cattle rabies in Europe, birds flu and that kind of stuff, but less political since its smaller (socially) fragrance field.
Companies adore, I guess, to scatter and spread various public fears bashing each other on the market.
Really, A LOT of stuff around that we use contains hazardous chemicals (air, food, water ...).
AFAIK, it's been a long time since a substantial part of fragrance ingredients became chemicals (as opposed to natural essences). That's a part of industrial way of production.
I'm not buying "Creed uses all natural materials". That's marketing BS, IMO.
I do think all-natural stuff exists but more in a way of attars from Arabian East, priced sky high.
Indian oils are nit that pricy, but you have to do the composition yourself since it's mono-scent stuff.
Not that hazardous, really ;D
