Applicant's summary and conclusion
- Interpretation of results:

- Remarks:
- according to EU CLP (EC No. 1272/2008 and its amendments).
- Conclusions:
- The oral LD50 in rats was determined to be 4500 mg/kg bw.
- Executive summary:
In an acute oral toxicity study conducted using a protocol similar to OECD guideline 401 (performed before GLP principles were implemented), undiluted test substance was administered via oral gavage to fasted Wistar rats (five males + five females/dose) at dose levels of 3.18, 3.96, 5 and 6.30 mL/kg. The animals were sluggish soon after administration. In the higher dose groups mortality was observed within 24 hours of dosing, while no mortality was observed after 7 days. Necropsy did not reveal any pathological effects. The LD50 was 4.21±1 mL/kg bw (4500 mg/kg bw) both for the 24 hour and 7 day observation period.
