About

A polycyclic woody/amber fragrance methoxy compound — used at low % with IFRA-class controls.

Hexahydromethoxy-methanoindenes are a class of polycyclic methoxy-terpenoid fragrance materials contributing woody/amber character to perfume compositions. Typical of modern specialty fragrance chemicals, they are used at fractional percentages in fine fragrance and functional products. IFRA/RIFM guidance governs maximum concentrations; independent public toxicology for the exact INCI variant is limited. Nothing in this class currently triggers high-concern classification; ordinary fragrance-sensitization guidance applies.
