Two groups, each of three female WISTAR Crl: WI(Han) rats, were treated with the test item by oral
gavage administration at a dosage of 2000 mg/kg body weight. The test item was dissolved with the
vehicle aqua (sterile water) at a concentration of 0.2 g/mL and administered at a dose
volume of 10 mL/kg.

- Remarks:
- aqua (sterile water)
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 0.2 g/ml
- Amount of vehicle (if gavage): 10ml/kg bw
- Justification for choice of vehicle: non-toxic characteristics.

Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- none
- Clinical signs:
- other: minor signs of toxicity with slight piloerection within 4 hours after application. One animal continued to show slight piloerection on the day after application and recovered within 2 days post-dose.
- Gross pathology:
- no findings
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the present study, a single oral application of the test item TMA-TEMPO to
rats at a dose of 2000 mg/kg body weight was not associated with signs of toxicity or mortality.
The median lethal dose of TMA-TEMPO after a single oral administration to female rats, observed
over a period of 14 days is:
LD50 cut-off (rat): >5000 mg/ kg bw
