Ethyl 2-methyl-1,3-dioxolane-2-acetate (CAS # 6413-10-1) was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that ethyl 2-methyl-1,3-dioxolane-2-acetate is not genotoxic. Data from ethyl 2-methyl-1,3-dioxolane-2-acetate show that there are no safety concerns for skin sensitization under the current, declared levels of use. Data on ethyl 2-methyl-1,3-dioxolane-2-acetate provide a calculated MOE >100 for the repeated dose, developmental, and reproductive toxicity endpoints. The local respiratory toxicity endpoints were evaluated using the TTC for a Cramer Class III material, and the exposure to ethyl 2-methyl-1,3-dioxolane-2-acetate is below the TTC (0.47 mg/day). The phototoxicity/photoallergenicity endpoints were evaluated based on UV spectra; ethyl 2-methyl-1,3-dioxolane-2-acetate is not expected to be phototoxic/photoallergenic. For the environmental endpoints, ethyl 2-methyl-1,3-dioxolane-2-acetate is not PBT as per the IFRA Environmental Standards, and its risk quotients (i.e., PEC/PNEC) for the aquatic environment based on its current volume of use in Europe and North America are <1.
