Abstract

The existing information supports the use of this material as described in this safety assessment. Methyl-2,2-dimethyl-6-methylene-1-cyclohexanecarboxylate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that methyl-2,2-dimethyl-6-methylene-1-cyclohexanecarboxylate is not genotoxic. Data on methyl-2,2-dimethyl-6-methylene-1-cyclohexanecarboxylate provide a calculated Margin of Exposure (MOE) >100 for the repeated dose toxicity endpoint. The 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 methyl-2,2-dimethyl-6-methylene-1-cyclohexanecarboxylate is below the TTC (0.03 mg/kg/day and 1.4 mg/day, respectively). Data show that there are no safety concerns for methyl-2,2-dimethyl-6-methylene-1-yclohexanecarboxylate for skin sensitization under the current declared levels of use. The phototoxicity/photoallergenicity endpoints were evaluated based on ultraviolet (UV) spectra; methyl-2,2-dimethyl-6-methylene-1-cyclohexanecarboxylate is not expected to be phototoxic/photoallergenic. The environmental endpoints were evaluated; methyl-2,2-dimethyl-6-methylene-1-cyclohexanecarboxylate 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.
