About

Trimethyl-methylbutenyl-bicycloheptan-3-one is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This is a bridged bicyclic ketone with a trimethylnorbornane skeleton and a methylbutenyl substituent, creating a complex, rigid steroidal-like structure. Ketones of this type are used in fragrance compositions for woody, amber notes. Limited toxicological data are available for this specific compound. EU cosmetics regulation does not specifically list it, but it would fall under general fragrance safety provisions of IFRA and the EUallergen guidance framework.

Known concerns

  • Limited toxicological data available
