Escentric Molecules Molecule 01 Unisex Perfume, launched in 2006 by Escentric Molecules, is sure to be the most unusual and exciting scent in your collection. It contains one fragrance note: Iso E Super. Iso E Super is the trademarked name for a large organic molecule whose feminine, velvet-woody scent vanishes at first, only to reappear when the warmth of your skin and your unique body chemistry allow it to release a distinctive fragrance. This fragrance makes a fun and interesting gift for those interested in science or needing a new fragrance.
