- Based on:
- test mat.
- Mortality:
- None of the animals died during the study period.
- Clinical signs:

- No abnormalities were noted at necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the study, the acute oral LD50 of the test material was determined to be in excess of 5000 mg/kg bw.
- Executive summary:
The acute oral toxicity of the test material was evaluated in a study which was conducted under GLP conditions and in accordance with the standardised guidelines EU Method B.1 and OECD 401.
During the study, the test material was administered by oral gavage to one group of five male and five female Sprague-Dawley rats at 5000 mg/kg bw. The volume administered to each animal was calculated according to its fasted bodyweight at the time of dosing. All animals were subject to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice on day 15.
None of the animals died during the study and no clinical signs were noted. The mean body weight gain shown by the animals over the study period was considered to be similar to that expected of normal untreated animals of the same age and strain. Furthermore, no abnormalities were found at macroscopic post mortem
examination of the animals.
Therefore, under the conditions of the study, the oral LD50 value of the test material in male and female Sprague-Dawley rats was in excess of 5000 mg/kg bw, the highest permissible dose level tested.
