Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute oral median lethal dose (LD50) of test chemical in male/female sprague-dawley rat was determined to be 8440-9710 mg/kg of body weight. LD50 value indicates that the test chemical does not exhibits acute toxicity by the oral route.
- Executive summary:
The acute oral toxicity of test chemical was performed in Sprague-Dawley rats . For this purpose, the product was administered once by gavage as a 50% solution in aqua dest . in doses of 5620, 6810, 8250 and 10000 mg/kg .
The median lethal dose (LD 50) after 14 days was observed to be 8980 (8440 - 9710) mg/kg in male and female rats.In male animals LD50 value was observed to be 9140 (8350 - 10510) mg/kg whereas in female animals ,8820 (7960 - 10090) mg/kg.
From the above study it is concluded that test chemical does not exhibits acute toxicity by the oral route.
