Results and discussion
Effect levels
- Sex:
- not specified
- Dose descriptor:
- LD50
- Effect level:
- ca. 30 mg/kg bw
- Mortality:
- no data
- Clinical signs:
- ataxia, dyspnea, tremor

Applicant's summary and conclusion
- Conclusions:
- The intraperitoneal LD50 in the mouse is approximately 30 mg/kg bw. As the intraperitoneal LD50 of indigo powder proved to be approximately 8000 mg/kg bw, the significantly lower dermal LD50 of Indigoküpe 60% Körner is most likely due to the 5% alkali content.
