California's Campaign for Safe Cosmetics and a Toronto team tested 17 fragrances. On average, each contained 14 secret compounds.
Some had more -- Including American Eagle 77, Britney Spears Curious, Giorgio Armani Acqua Di Gio, Old Spice and Calvin Klein Eternity.
Some industry leaders say the amounts are so miniscule, and can't hurt you.
