Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Due to the LD50>2000 mg/kg bw the substance is not subject for classification for acute oral toxicity.
- Executive summary:
The substance was tested for acute oral toxicity to the Wistar-rat according to OECD guideline 401. A pre-test was performed with one male and one female rat for each dose of 500, 1000 and 2000 mg/kg bw. There was no mortality in this pre-test. For the main test 5 male and 5 female animals were administered a single dose of 2000 mg/kg bw by gavage. No mortality occured up to the observation period of 14 days but unspecific symptoms such as squatting posture, pinched in flanks and increased respiration could be noticed. Two dayas after the application these symptoms were completely reversible.
There was no effect on the development of the body weight and after section of the killed animals no macroscopic findings were present.
The LD50 is therefore greater than 2000 mg/kg bw
