I just found an interesting list that someone has compiled of the chemicals/ingredients that are used in fragrances. I don't know how accurate it is (it was compiled in 1997) but the quick scan I've had looks about right. It's a scary looking list and what I find more scary is that cosmetics companies don't have to disclose what chemicals make up the fragrance part of their products.

Anyway, just for reference. Enjoy
