Applicant's summary and conclusion

- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute oral median lethal dose (LD50) of the test material in male and female Hanlbm: WIST (SPF) strain of rat was greater than 2000 mg/kg body weight.
- Executive summary:
The study was performed to EU Method B.1 and OECD 423 in accordance with GLP to assess the acute oral toxicity of the test material in the Hanlbm: WIST (SPF) strain of rat. The test material was administered orally, after fasting for 1 hour, once only by gavage. The test material concentration in the vehicle was 200 mg/ml and the administered volume of suspension was 10 ml/kg body weight. 3 male and 3 female test animals were dosed at 2000 mg/kg body weight. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy after an observation period of 15 days. There were no deaths but slight rales were noted in all female animals on test day 2. Somnolence was observed in all male animals from 2 to 5 hours after the administration and slightly ruffled fur was observed in the same males from 1 to 5 hours (2 males) or from 2 to 5 hours (1 male). Hunched posture was observed additionally in one male animal (no.4) from 1 to 5 hours after the administration. Animals showed expected gains in bodyweight during the study. No test-related abnormalities were noted at necropsy. The acute oral median lethal dose (LD50) of the test material in the male and female Hanlbm: WIST (SPF) strain rat was greater than 2000 mg/kg bodyweight.
