Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS- Age at study initiation: Young adult animals- Weight at study initiation: animals of comparable weight (150g - 300g) (+/- 20% of the mean weight)- Housing: stainless steel wire mesh cages, type DK-III (single housing)- Diet (e.g. ad libitum): ad libitum (feed assayed for chemical and microbiological contaminants)- Water (e.g. ad libitum): Tap water ad libitum per day- Acclimation period: acclimatization for at least 1 weekENVIRONMENTAL CONDITIONS- Temperature (°C): The animals were housed in fully air-contitioned rooms. Central air-conditioning guaranteed a range of 20 - 24 degrees centigrade for temperature and of 30 - 70 % for relative humidity. There were no deviations from these ranges, which influenced the results of the study.- Photoperiod (hrs dark / hrs light): 12 h/12 h
Administration / exposure
- Route of administration:

- No. of animals per sex per dose:
- 3 males / 3 females
- Control animals:
- not specified
- Details on study design:
- - Duration of observation period following administration: 14 days - Examinations performed: clinical signs and symptoms, body weight,mortality, pathology: yes
Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality.
- Clinical signs:
- other: Signs of toxicity noted in female animals comprised impaired general state, dyspnoea and staggering. These syptoms were considered to be unspecific toxicity symptoms. The animals appeared normal 2 days after application.The male rats did not show any sym
- Gross pathology:
- No abnormalities were noted at necropsy of animals sacrificed at the end of the study.
Applicant's summary and conclusion
- Conclusions:
- Under the test conditions, the LD50 value of the test substance was > 2,000 mg/kg bw.
- Executive summary:
A study was conducted to determine the acute oral LD50 of the test substance according to EPA OPPTS 870.1100, OECD Guideline 423 and EU Method B.1.
No mortality was observed at the dose level of 2,000 mg/kg bw .
Under the conditions of the study, the LD50 of the test substance was therefore >2,000 mg/kg bw.
