- Vehicle:
- water
- Remarks:
- Buffered to pH 7.4
- Details on oral exposure:
- Buffered to ca pH 7 to avoid local corrosivity effects
- Doses:
- 296, 395, 500, 650, and 845 mg/kg reported (hydrated material)
ca 207, 277, 350, 455 and 591 mg/kg of anhydrous material. - No. of animals per sex per dose:

Results and discussion
Effect levels
- Sex:
- male
- Dose descriptor:
- LD50
- Effect level:
- ca. 290 mg/kg bw
- Based on:
- act. ingr.
- Mortality:
- The top dose of ca 590 mg/kg actives led to 10/10 mortality. Other dose levels showed reduced mortality and the lowest treatment level of 207 mg/kg had full survival.
- Clinical signs:
- other: The top dos caused ataxia, diarrhoea, irregular respiration and changes in cardiac rhythm. Clinical and physical signs typically appeared within 24 hours, and in surviving animals, had resolved 48 hours after administration.
- Gross pathology:
- Not reported
Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- Although precise details were not provided in the publication, the result allow for classification.
Further animal testing is not justified.
Only the rat data has been included in this summary.
