Results and discussion
Effect levels
- Key result
- Sex:
- male
- Dose descriptor:
- LD50
- Effect level:
- 5 600 mg/kg bw
- Based on:
- test mat.
- Remarks:
- median-effect dose, calculated from the 14-day mortality data
- Remarks on result:
- other: No range is given because there was 100% mortality at 7.95 g/kg bw and 100% survival at 3.98 g/kg bw
- Mortality:
- All animals administered the higher dose died. No mortalities were seen at the lower dose.
- Clinical signs:
- other: 3.98 g/kg bw: no data available At 7.95 g/kg bw: Violent convulsions followed the administration of the doses and death ensued in a few hours.
- Gross pathology:
- 3.98 g/kg bw: no data available
At 7.95 g/kg bw: Lungs were hemorrhaged, livers and kidneys mottled and adrenals slightly congested at autopsy. - Other findings:
- No data available.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In an acute oral toxicity study available from an IUCLID summary, claimed to be conducted using a protocol comparable to the now deleted OECD Test Guidelines 401, but predating GLP, the LD50 was determined to be 5600 mg/kg bw/day in male Wistar rats.
