Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the test conditions, the acute oral medial lethal dose (LD50) of the test substance was found to be >2,000 mg/kg in male and female wistar rats.
- Executive summary:
A study was conducted to assess the acute oral toxicity of test substance in wistar rats equivalent or similar to EU Method B.1. and OECD guideline 401 in compliance with GLP.
A group of five male and five female rats received a single oral dose of 2000mg/kg (adjusted for water content) of the test sample as a preparation in corn oil. The animals were assessed daily for any signs of toxicity and their bodyweights were recorded at intervals.
None of the animals died and there were no significant signs of toxicity. There were no treatment-related abnormalities at post mortem examination. The acute oral median lethal dose was in excess of 2000mg/kg to male and female rats.
Under the test conditions, the acute oral medial lethal dose (LD50) of the test substance was found to be >2,000 mg/kg in male and female wistar rats.
