1-(Octahydro-2,3,8,8-tetramethyl-2-naphthalenyl)ethanone

Iso E Super (1-(Octahydro-2,3,8,8-tetramethyl-2-naphthalenyl)ethanone) is a synthetic woody-amber fragrance molecule developed by International Flavors & Fragrances (IFF) in the 1970s, belonging to the cedryl ketone family. It is renowned for its unique 'skin-like' warmth, velvety cedar-wood character, and remarkable tenacity, and is famously used as a near-solo ingredient in Escentric Molecules' Molecule 01 perfume. Formulators prize it for its exceptional blending versatility and its ability to amplify and smooth other fragrance notes, acting as a transparent woody base that enhances the overall olfactory profile of a composition.
