Applicant's summary and conclusion

Interpretation of results:
other: Not classified
Conclusions:
The acute oral LD50 value was determined to be 2900 mg/kg bw, with 95% confidence limit of 2400-3400 mg/kg bw, when male and female CFY rats were treated with the given test substance via oral gavage route.
Executive summary:

The acute oral toxicity study was conducted by using of the given test chemical inmale and female CFY rats at the dose concentration of 2900 mg/kg bw.

The given test chemical was prepared as 10% suspension in 0.5% carboxymethylcellulose and administered via oral route.

The animals were observed for mortality. 50% mortality was observed at 2900 mg/kg bw in treated animals.

Hence, the LD50 valuewas determined to be 2900 mg/kg bw, with 95% confidence limit of 2400-3400 mg/kg bw, when male and female CFY rats were treated with the given test substance via oral gavage route.
