Applicant's summary and conclusion

Interpretation of results:
not classified
Conclusions:
LD50 was considered t be > 5000 mg/kg bw when rats were treated with nonan-2-one orally.
Executive summary:

In a acute oral toxicity study, 10 rats were treated with nonan-2-one in the concentration of 5000 mg/kg bw orally. Death of one out of ten rats was observed at 5000 mg/kg bw. Therefore, LD50 was considered t be > 5000 mg/kg bw when rats were treated with nonan-2-one orally.
