- TEST ITEM PREPARATION
- The test item was placed into a glass beaker on a tared Mettler PK 300 balance, and the vehicle polyethylene glycol (PEG 400) was added. A weight by volume dilution was prepared using a homogeniser.

Applicant's summary and conclusion
- Interpretation of results:
- other: not classified according to the CLP Regulation (EC) No.1272/2008
- Conclusions:
- The LD50 (oral, rat) of test item was found to be greater than 5000 mg/kg bw
- Executive summary:
Acute oral toxicity of the substance was evaluated in an experimental study performed according to the OECD Guideline 401 (1987) and EU method B.1 (1984).
No mortality was observed at 2000 mg/kg bw, and 20 % mortality was observed at the higher dose of 5000 mg/kg bw. Toxic symptoms of sedation, dyspnoea, hunched posture and ruffled fur were observed in one male and one female animal administered 2000 mg/kg bw until day 4 and 5, respectively at 2000 mg/kg bw; toxic symptoms of sedation, dyspnoea, ataxia, hunched posture, diarrhoea and ruffled fur were observed in 1 - 2 male and 1 - 2 female animals until day 3 at 5000 mg/kg bw. Body weights of all animals remained constant. No gross pathological changes were observed among animals administered at 2000 mg/kg bw or the surviving animals administered at 5000 mg/kg bw; the two animals of the higher dose who died during the study period were found to have several dark red foci, partly black, of the lungs and black liver, stomach, intestines, kidneys, adrenal glands and spleen. The LOGIT-Model could not be applied to these data. Based on these findings, the acute oral toxicity of the test item in rats of both sexes, observed over a period of 15 days, was estimated to be greater than 5000 mg/kg bw Therefore, it can be extrapolated that the LD50 is greater than 5000 mg/kg bw.
