Applicant's summary and conclusion
- Conclusions:
- Under the present test conditions, the test item requires no labelling, as LD50 > 2000 mg/kg b.w., p.o.
- Executive summary:
The test item is given to female rats by oral administration to obtain information on the toxicity, in particular, lethality of a test item
Under the present test conditions, a single oral administration of 2000 mg test substance to female rats did not reveal any signs of toxicity. No animal died prematurely. All animals gained the expected body weight.
No pathological changes were observed at necropsy
Therefore, the test substance is non toxic if swallowed, as LD50 > 2000 mg/kg b.w., p.o.
