説明
The existing information supports the use of this material as described in this safety assessment. 2,2-Dimethyl-3-methyl-3-butenyl propanoate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog rhodinyl formate (CAS # 141-09-3) show that 2,2-dimethyl-3-methyl-3-butenyl propanoate is not expected to be 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 2,2-dimethyl-3-methyl-3-butenyl propanoate 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 non-reactive materials (900 μg/cm
