Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute oral toxicity dose (LD50) value was considered to be >5000 mg/kg bw, when male and female Sprague-Dawley rats were treated with test chemical via oral gavage route.
- Executive summary:
The acute oral toxicity study was conducted by using test chemical in 10 male and female Sprague-Dawley rats at the dose concentration of 5000 mg/kg bw. A 25% w/v suspension of the compound in a 50% aqueous solution of polyethylene glycol (vehicle) was administered as a single dose by gavage to rats which had been fasted for 18 hours, at a dose rate of 20ml/kg. (Equivalent to 5g/kg. compound). After administration of the compound, the animals were observed for 14 days. Deaths and clinical symptoms were recorded. At the end of the observation period surviving animals were killed by exsanguination under ether anaesthesia and an autopsy performed. Two male died at 164 and 175 hours respectively after administration of the compound. One male animal showed severe respiratory distress.At autopsy no changes in organs or tissues caused by the administration of the test compound were seen. Therefore, LD50 value was considered to be >5000 mg/kg bw, when male and female Sprague-Dawley rats were treated with test chemical via oral gavage route. This toxicity value does not fall in the range of classification within the EU CLP regulation and thus the substance is not considered to be classified in the toxic category.
