Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The substance demonstrated a 30% mortality rate and has been completed as a limit test at 5000 mg/kg The LD50 is considered to be >5000 mg/kg.

Executive summary:

The test sample was dosed orally to 5 male and 5 female rats at a dose of 5000 mg/kg. Assessed over a 14 day period, 1 male and 2 female deaths occured and the study was completed as a limit test. The LD50 is considered >5000 mg/kg.

No classification is applicable on the basis of the results.
