Verdone (IFF) is primarily a powerful camphoraceous/minty odour, but don't click away just yet. 
 
In perfumery mint notes are remarkably hard to deploy, especially in fine fragrances where the association all too often veers towards toothpaste or toilet cleaner. So any minty or camphoraceous notes which resist this connotation are to be celebrated, in my view. 
 
Verdone, which is the ketone version of Verdol, is decidedly spiky but with an interesting metallic clinkiness a little bit reminiscent of Safraleine.  While Safraleine is primarily saffron/leather but with an almost kaleidoscopic powdery-fruity-tobacco (even benzaldehyde) adjacency, Verdone is completely monochromatically unfruity.
