TETRAHYDRO-HEXAMETHYL-AS-INDACEN-3-ONE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

Tetrahydro-hexamethyl-as-indacen-3-one is a synthetic polycyclic ketone related to the indane and indanone families. The saturated tetrahydro ring system reduces reactivity compared to unsaturated analogs, while the multiple methyl substituents create a distinctive musky, ambery, and slightly woody odor profile reminiscent of certain timber notes. Indanone derivatives have a history of use in fine fragrances. No EU restrictions specifically apply to this compound class, and the saturated ring structure is favorable for skin tolerance.
