- other: not classified according to the CLP Regulation (EC 1272/2008)
- Conclusions:
- LD0 = 2000 mg/kg
LD50 > 2000 mg/kg - Executive summary:
Method
Test substance was administered to 5/rat/sex by gavage at dose of 2000 mg/kg. Test animals were observed for 14 days after dosing.
Results
No mortality was recorded, thus LD0 = 2000 mg/kg and LD50 > 2000 mg/kg.
