Applicant's summary and conclusion
- Conclusions:
- NOAEL was considered to be 100 mg/kg/day for maternal study and 200 mg/kg/day for teratogenicity study when female rat were exposed to 2-chloro-p-phenylenediamine (o-chloro-p-PD).
- Executive summary:
In a teratogenicity study, female Sprague-Dawley rat were exposed to 2-chloro-p-phenylenedia mine (o-chloro-p-PD) orally in the concentration of 0, 100, 200 and 400 mg/kg/day. In the parental generation, decreased in mean body weight were observed in 200 and 400 mg/kg/day treated rat as compared to control . In addition,significant increase in the number of resorptions were observed in female rat. Effect on male and female fetal weight was observed when treated with 400 mg/kg/day. Therefore, NOAEL was considered to be 100 mg/kg/day for maternal study and 200 mg/kg/day for teratogenicity study when rats are exposed to 2-chloro-p-phenylenediamine (o-chloro-p-PD) orally for 10 days.
