In vivo test system
Study design: in vivo (LLNA)
- Vehicle:
- dimethylformamide
- Concentration:
- Groups of four mice were treated with the test item at 100% and diluted at 50% and 25% in the vehicle Dimethyl formamide (DMF).
- No. of animals per dose:
- four mice per dose
- Details on study design:
