Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): negative
The substance doesn't induce micronucleus in the mouse - Executive summary:
The micronucleus test has been performed in mouse (males and females) with the substance by ip injection of 200 to 2000 mg/kg. The micronucleus were determined at 24 or 48 h after treament for the highest tested dose and at 24 h only for 200 and 670 mg/kg. Sign of toxicity were observed at 2000 mg/kg.
In the conditions of this test, the substance didn't induce positive results.
