Applicant's summary and conclusion
- Conclusions:
- The NOEL (No Observed Effect Level) for general toxicity in males and females was considered to be below 50 mg/kg/day, but the NOAEL (No Observed Adverse Effect Level) for general toxicity in males and females was considered to be 200 mg/kg/day.
The NOEL (No Observed Effect Level) and the NOAEL (No Observed Adverse Effect Level) for reproduction/developmental toxicity was considered to be 200 mg/kg/day. - Executive summary:
