Iso E Super is an abstract synthetic molecule characterized as a cedarwood note with a warm, velvety cocooning sensation. Iris is a natural extracted from the root of several varieties of iris."It's not easy to describe iris' smell as such, but if you smell a fragrance without it, and then with it, you understand immediately what it does. It adds a creamy powderiness. It brings a physical dimension to a fragrance. I have had a longstanding love affair with iris. Every Escentric fragrance has an iris note somewhere in there. To me, iris is luxury. The iris pallida absolue I've used here is one of the most expensive ingredients in perfumery. You can find iris extracts for way less than that. But they do not have the great and subtle beauty of this absolue. It's radical to put this much in a fragrance. The sillage is fantastic. This is a bomb, but a subtle bomb." Geza
