Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River (UK)
- Age at study initiation: 8-12 weeks
- Weight at study initiation: 227-243 g (males) and 200-214 g (females)
- Fasting period before study:
- Housing: The animals were housed in groups of up to 5 by sex in solid-floor polypropylene cages furnished with woodflakes.
- Diet: ad libitum; with the exception of an overnight fast immediately before dosing
- Water: ad libitum
- Acclimation period: 5 days
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19-22
- Humidity (%): 50-56
- Air changes (per hr): 15
- Photoperiod: 12 hours dark/light cycle
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- arachis oil
- Details on oral exposure:
- The volume administered to each animal was calculated according to its fasted body weight at the time of dosing.
- Doses:
- Based on the results of a range-finding study a group of animals was treated as follows:
Dose level: 2000 mg/kg
Concentration: 200 mg/ml
Dose volume: 10 ml/kg - No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- not specified
- Details on study design:
- The animals were observed for deaths or overt signs of toxicity 0.5, 1, 2 and 4 hours after dosing and subsequently once daily for 14 days. Individual body weights were recorded prior dosing on day 0 and on days 7 and 14. At the end of the study the animals were killed and subjected to gross pathological examination. This consisted of an external examination and opening of the abdominal and thoracic carvities for examination of major organs. The appearance of any macroscopic abnormalities was recoded. No tissues were retained.
- Statistics:
- no data
Results and discussion
- Preliminary study:
- There were no daeths or clinical signs of toxicity. Based on this information, a dose level of 2000 mg/kg body weight was selected for the main study.
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- There were no deaths
- Clinical signs:
- other: No signs of systemic toxicity were noted during the study.
- Gross pathology:
- No abnormalities were noted at necropsy.
- Other findings:
- no
Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information at the tested dose Criteria used for interpretation of results: EU
- Conclusions:
- The acute oral median lethal dose of the test material was found to be greater than 2000 mg/kg body weight. No symbol and risk phrase are required according to EU labelling regulations.
