Test animals
- Species:
- rat
- Strain:
- other: Hanlbm: WIST (SPF)
- Sex:
- male/female
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5
- Details on study design:
- The test article was suspended in vehicle (bi-distilled water) at a concentration of 0.2 g/ml and administered at a volume of 10 ml/kg. Four times during day 1 and once daily during days 2-15 the animals were examined for clinical signs.
Mortality/viability were recorded together with clinical signs at the same time intervals. Body weights were recorded on day 1 prior to administration and on days 8 and 15. All animals were necropsied and examined macroscopically.
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No deaths occurred during the study.
- Clinical signs:
- No clinical signs of toxicity were observed during the observation period.
- Body weight:
The body weight of the animals was within the range of physiological variability known for rats of this strain and age.- Gross pathology:
- No macroscopic organ findings were observed at necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- other: not classified within the CLP Regulation (EC 1272/2008)
- Conclusions:
- LD50 > 2000 mg/kg bw
