Applicant's summary and conclusion

Interpretation of results:
Category 4 based on GHS criteria
Conclusions:
LDLo (LD60) was considered to be 1600 mg/kg when mice were treated with 1-Butanaminium, N,N,N-tributyl-, iodide (1:1) orally.
Executive summary:

In acute oral toxicity study, micetreated with 1-Butanaminium, N,N,N-tributyl-, iodide (1:1) in the concentration of 1600mg/kg orally and observed for 72 hours.60 % Mortality was observed in treated mice at 1600 mg/kg. Therefore,LDLo (LD60) was considered to be 1600 mg/kg when mice were treated with 1-Butanaminium, N,N,N-tributyl-, iodide (1:1) orally.
