N2 - The existing information supports the use of this material as described in this safety assessment. 2,6-Nonadienenitrile was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that 2,6-nonadienenitrile is not genotoxic. Data on read-across analog E- and Z-2(+3),12-tridecadiennitrile (CAS # 124071-40-5) provided 2,6-nonadienenitrile 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 III material, and the exposure to 2,6-nonadienenitrile is below the TTC (0.0015 mg/kg/day and 0.47 mg/day, respectively). Data show that there are no safety concerns for 2,6-nonadienenitrile for skin sensitization under the current declared levels of use. The phototoxicity/photoallergenicity endpoints were evaluated based on ultraviolet/visible (UV/Vis) spectra; 2,6-nonadienenitrile is not expected to be phototoxic/photoallergenic. The environmental endpoints were evaluated; 2,6-nonadienenitrile 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.
