N2 - The existing information supports the use of this material as described in this safety assessment. This material has not been fully evaluated for photoallergenic potential. 2,4,6-Cycloheptatrien-1-one, 2-hydroxy-4-(1-methylethyl)- was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, photoirritation/photoallergenicity, skin sensitization, and environmental safety. Data show that 2,4,6-cycloheptatrien-1-one, 2-hydroxy-4-(1-methylethyl)- is not genotoxic. The repeated dose, reproductive, and local respiratory toxicity endpoints were evaluated using the Threshold of Toxicological Concern (TTC) for a Cramer Class I material, and the exposure to 2,4,6-cycloheptatrien-1-one, 2-hydroxy-4-(1-methylethyl)- is below the TTC (0.03 mg/kg/day, 0.03 mg/kg/day, and 1.4 mg/day, respectively). The skin sensitization endpoint was completed using the Dermal Sensitization Threshold (DST) for reactive materials (64 μg/cm2); exposure is below the DST. Based on data, 2,4,6-cycloheptatrien-1-one, 2-hydroxy-4-(1-methylethyl)- is a photoirritant but is not a concern under the current declared use levels. 2,4,6-Cycloheptatrien-1-one, 2-hydroxy-4-(1-methylethyl)- was not evaluated for photoallergenicity. The environmental endpoints were evaluated; for the hazard assessment based on the screening data, 2,4,6-cycloheptatrien-1-one, 2-hydroxy-4-(1-methylethyl)- 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 (VoU) in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are <1.
