Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- oral LD50 ca. 3400 mg/kg (male/female)
- Executive summary:
In a study comparable to OECD guideline 401, the LD50 for oral acute toxicity in rats was calculated as ca. 3400 mg/kg body weight. Doses of 212, 1696, 2120, 2650, 3392, 4240, 5300, and 6784 mg/kg bw of an aqueous solution were applied by gavage followed by a post dose observation period of 7 days. Main clinical signs observed were staggering, apathy, irregular respiration, shallow flanks, abdomial position, closed eyes, ruffled fur. At necropsy, gastrorrhagia, sagged gastrointestinal tract and serous smeared snouts were observed.
