Applicant's summary and conclusion

Conclusions:
NOAEL was considered to be 405.0 mg/kg bw for P and F1 generation when Syrian female hamsters were treated with test material orally by gavage during gestation days 6-10.
Executive summary:

In a Reproductive Toxicity study,Syrian female hamsters were treated with test material in the concentration of 4.05, 21.15, 98.2 and 405.0 mg/kg bw/day orally by gavage during gestation days 6-10. No effect on survival of treated female hamsters and fetus were observed. Similarly, No effect on Reproductive performance of treated female hamsters was observed.In addition, No dose-related number of abnormalities in soft or skeletal tissues were observed in fetus of treated hamsters were observed.Therefore, NOAEL was considered to be 405.0 mg/kg bw for P and F1 generation when Syrian female hamsters were treated with test material orally by gavage during gestation days 6-10.
