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: In principle, the methods described in the OECD Guideline 401 were used. Several groups of 5 rats per sex and dose were treated simultaneously by gavage with preparations of the test substance in suitable vehicle. The concentrations of these preparations were used to achieve comparable volumes per kg body weight. Group-wise documentation of clinical signs was performed over the 14 day study period. Body weight was determined before the start of the study only, as it was needed for determination of dose.
- GLP compliance:
- no
- Test type:
- standard acute method
- Limit test:
- no
