- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Mortality / Viability: Daily during the acclimatization period, at approximately 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2-15.
Body weights: On test days 1 (prior to administration), 8 and 15.
Clinical signs: Daily during acclimatization and at approximately 1, 2, 3 and 5 hours after administration on test day 1. Once daily during days 2-15. All abnormalities were recorded.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the observations the median lethal dose of the test substance is greater than 2000 mg/kg body weight
- Executive summary:
In a GLP compliant oral toxicity study, performed according to OECD guideline 423, Wistar rats (2 groups of 3 females) were administered the test substance (2000 mg/kg bw) by oral gavage followed by a 14-day observation period. All animals survived until the end of the study period. No clinical signs were observed during the course of the study. Three out of six animals showed dark feces on test day 2. The body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were recorded at necropsy. Based on the observations, the median lethal dose of the test substance in female rats observed for a period of 14 days was greater than 2000 mg/kg bw.
