Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The test item had an LD50 of 1310 mg/kg in the current study.
- Executive summary:
In the current study the acute oral toxicity of the test item was assessed. The methodology of the study was not described, therefore, it is assumed it was not according to OECD guideline. It was not indicated that the study was according to GLP.
In total 50 rats (10 rats/dose) were treated by oral route with a single dose of the test item at dose 830 mg/kg, 1040 mg/kg, 1310 mg/kg, 2050 mg/kg and 5000 mg/kg.
Following dosing, the animals were observed for 14 days.
At dose level 1040 mg/kg bw, 3/10 animals died on Day 2 after dosing. At dose level 1310 mg/kg, 5/10 animals died (3 on Day 1 after dosing and 2 on Day 2 after dosing). At dose level 2050 mg/kg, 8/10 animals died (1 on Day 1 after dosing and 7 on Day 2 after dosing). At dose level 5000 mg/kg, 9/10 animals died (3 on Day 1 after dosing, 5 on Day 2 after dosing and 1 on Day 3 after dosing).
No clinical signs were observed. Body weight was not specified in the study report. Skin irritation occurred: slight redness in 4/8 animals, moderate redness in 2/8 animals, and slight edema in 2/8 animals.
As the test item induced the death of the half of the animals at dose level 1310 mg/kg, the test item should be classified according to 1272/2008 CLP regulation as Acute Oral toxicity Category 4.
