Safety
Safety Profile
The Research Institute for Fragrance Materials (RIFM) has assessed its use as a fragrance ingredient, concluding it is not genotoxic and poses no phototoxicity/photoallergenicity risk. While existing data suggest it can act as a sensitizer, RIFM found no safety concerns at current fragrance use levels, as exposure remains below the Dermal Sensitization Threshold. Conversely, the European Chemicals Agency (ECHA) GHS classification indicates it is harmful if swallowed, may cause an allergic skin reaction, and is noted as 'Irritating to skin' and 'May cause sensitisation by skin contact'. The FDA lists it as a flavoring agent (FEMA 3421, JECFA 1857), though there is a record of the FDA no longer providing for the use of certain synthetic flavoring substances, which may relate to specific contexts for this ingredient.

Verdict
While a component of saffron, TRIMETHYL-2-CYCLOHEXENE-1,4-DIONE lacks documented skin-specific mechanisms or clinical efficacy data for skincare applications, and carries a moderate risk of skin irritation and sensitization based on regulatory classifications, despite RIFM's findings at low fragrance concentrations.
