Molecule 01 Perfume by ESCENTRIC MOLECULES, Molecule 01, 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.
