About
Hexahydro-methanoinden-6-yl-isopentenol is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.
Hexahydro-methanoinden-6-yl-isopentenol (also known under trade names such as Sandalore or similar woody aroma chemicals) is a synthetic fragrance ingredient. Its chemical structure contains a bicyclic sesquiterpenic core with an isopentenyl side chain. The fragrance community (IFRA/RIFM) has assessed this class for phototoxicity and sensitisation. The primary concern is that unsaturated sesquiterpenic structures can oxidise on air exposure, forming sensitisers such as hydroperoxides. Standard IFRA recommendations restrict oxidized material. Not listed on EU Annex II or III, suggesting it is not a confirmed high-concern restricted substance — hence the score in the 60s.

- Provides woody, amber fragrance notes in cosmetic formulations
Known concerns
- Fragrance allergen — potential for skin sensitisation upon oxidation
