Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Remarks:
- According to Regulation (EC) No 1272/2008
- Conclusions:
- The acute median lethal oral dose (LD50) to rats of BMI was demonstrated to be greater than 2000 mg/kg bodyweight.
- Executive summary:
An acute oral toxicity study in rats was performed by oral gavage according to internationally accepted guidelines and in accordance with GLP principles. Following a preliminary dose at 300 mg/kg/bw that showed no lethality, a limit test was conducted at 2000 mg/kg/bw. No mortality or adverse signs were observed. This results in an LD50 >2000 mg/kg/bw.
