Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The acute oral LD50 value was considered to be 850 mg/kg body weight, when rats were treated with the given test chemical orally.
- Executive summary:
Acute oral toxicity study was done in rat using test material at dose concentration of 850 mg/kg bw. Animals were observed for mortality and signs of toxicity. 50% mortality observed at dose 850 mg/kg bw. Clinical signs like Somnolence (general depressed activity); Ataxia and Alteration of classical condition were observed. Hence, the acute oral LD50 value was considered to be 850 mg/kg body weight, when rats were treated with the given test chemical orally.
