- other: not classified based on CLP criteria.
- Conclusions:
- The acute dermal median lethal dose (LD50) of phenethyl propionate in rabbit was observed to be greater than 5000.0 mg/kg b.wt (>5000 mg/kg bw).
- Executive summary:
The acute toxicity study was examined to evaluate the toxic effects of administration of phenethyl propionate (CAS No. 122-70-3) in rabbit by the dermal route.The test material was administered topically to 10 rabbits followed by a 14 day observation period.Mortality was observed in one animal on day four. There were no clinical signs of toxicity.The acute dermal median lethal dose (LD50) of phenethyl propionate in rabbit was observed to be greater than 5000.0 mg/kg b.wt (>5000 mg/kg bw). Thus, according to CLP criteria for acute toxicity rating for the chemicals, it infers that of phenethyl propionate (CAS No. 122-70-3) can be classify under non toxic category at the tested dose level of 5000.0 mg/kg body weight.
