- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Females nulliparous and non-pregnant: yes
- Age at study initiation: approx. 8 -12 weeks
- Weight at study initiation: 177-179 g
- Fasting period before study: Feed was withdrawn from the animals at least 16 hours before administration, but water was available ad libitum .
- Housing: individually housed in stainless steel wire mesh cages, type DK-III
- Diet: ad libitum
- Water: ad libitum
- Acclimation period: at least 5 days
ENVIRONMENTAL CONDITIONS
- Temperature: 20 - 24°C
- Humidity: 30 - 70%
- Photoperiod: 12h/12h (6.00 a.m. - 6.00 p.m. / 6.00 p.m. - 6 .00 a.m.)
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- other: Olive oil Ph .Eur./DAB
- Details on oral exposure:
- VEHICLE
- Olive oil Ph .Eur./DAB
- Justification for choice of vehicle: Inhomogeneous in aqueous preparations. Olive oil Ph .Eur./DAB had to be used to ensure homogeneity of the preparation.
MAXIMUM DOSE VOLUME APPLIED: 5 mL/kg
DOSAGE PREPARATION: The test material preparation was produced for each administration group shortly before administration by stirring with a magnetic stirrer. This formed a solution.
CLASS METHOD

Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: Clinical observation in the 2,000 mg/kg administration groups revealed impaired general state, dyspnoea, staggering and piloerection and were observed from hour 1 until including hour 4 after administration.
- Gross pathology:
- No macroscopic pathologic abnormalities were noted in the animals examined at termination of the study.
Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified in accordance with EU Criteria
- Conclusions:
- Under the conditions of this study, the median lethal dose of the test material after oral administration was found to be greater than 2,000 mg/kg bw in rats.
- Executive summary:
The acute oral toxicity of the test material was investigated in accordance with the standardised guidelines OECD 423, EU Method B.1 tris and EPA OPPTS 870.1100, under GLP conditions.
During the study, single doses of 2,000 mg/kg body weight of test material preparations in olive oil Ph .Eur./DAB were given to two administration groups of three fasted female animals each, by gavage in a sequential manner.
No mortality occurred. Clinical observation revealed impaired general state, dyspnoea, staggering and piloerection. Findings were observed 1 to 4 hours after administration. The mean body weights of the administration groups increased throughout the study period and no macroscopic pathologic abnormalities were noted in the animals examined at the end of the observation period.
Under the conditions of this study, the median lethal dose of the test material after oral administration was found to be greater than 2,000 mg/kg bw in rats.
