l-Carvone was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that l-carvone is not genotoxic and provided a No Expected Sensitization Induction Level (NESIL) of 2600 μg/cm2 for the skin sensitization endpoint. Data on l-carvone provided a calculated Margin of Exposure (MOE) >100 for the repeated dose toxicity and reproductive toxicity endpoints. The phototoxicity/photoallergenicity endpoint was completed based on data and ultraviolet/visible (UV/Vis) spectra; l-carvone is not phototoxic/photoallergenic. The local respiratory toxicity endpoint was evaluated using the Threshold of Toxicological Concern (TTC) for a Cramer Class II material (0.47 mg/day); the exposure to l-carvone is below the TTC. The environmental endpoints were evaluated; l-carvone was found not to be persistent, bioaccumulative, and toxic (PBT) as per the International Fragrance Association (IFRA) Environmental Standards, and its risk quotients, based on its current volume of use in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are <1.
