Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 401 (Acute Oral Toxicity)
- Principles of method if other than guideline:
- BASF-test: The study was conducted according to an internal BASF method which in principle is comparable to the OECD Guideline 401. A test group consisting of 5 animals/sex was treated by single gavage application with an aqueous solution of the test substance. The animals were observed for mortality and for clinical symptoms of toxicity. At the end of the observation period of 7 days, the surviving animals were sacrificed for the purpose of necropsy; animals that died during the observations period also were subjected to necropsy.
- GLP compliance:
- no
- Test type:
- standard acute method
- Limit test:
- no
