Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 5 mL/kg bw
- Based on:
- test mat.
- Mortality:
- There was no mortality
- Clinical signs:
- other: Yellow mucoid diarrhoea was observed in seven of the ten animals 3 h after dosing. All animals appeared normal for the remainder of the study.
- Gross pathology:
- Gross necropsy revealed a dilated pelvis of the right kidney in one male rat, but this was not considered to be related to the material dosed.
- Other findings:
- No other findings specified.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LD50 was >5.0 mL/kg (dosed undiluted).
- Executive summary:
The test material was administered undiluted to 10 fasted Wistar rats as a single oral gavage dose of 5.0 mL/kg.
Yellow mucoid diarrhoea was seen in all the male animals and two females 3 hours after dosing. No other clinical signs were observed and no mortality occurred.
The LD50 was therefore >5.0 mL/kg.
