Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- Based on the results of this study the test article has an oral LD50 in the rat is greater than 2000 mg/kg.
- Executive summary:
The acute oral toxicity of the test article was evaluated in Wistar rats. This study was performed in accordance with Swiss GLP (2000) and OECD GLP (1997). The study design was based on OECD 423 (1996) and Directive 96/54/EEC, B.1 (1996).The test article was diluted in PEG 300 just prior to dosing. One group of 3 female rats and one group of 3 male rats received 2000 mg/kg of the test article via oral gavage at a dose volume of 10 mL/kg. The rats were observed at least 4 times during the first day postdose and then once daily for 14 days. Body weights were recorded pretest, weekly, and at termination. After the observation period, all animals were euthanized and examined for gross pathology. RESULTS: All animals survived. There were no abnormal clinical observations, body weight changes or necropsy findings in any animals. Based on the results of this study, the oral LD50 of the test article is greater than 2000 mg/kg.
