Description of key information
ORAL ROUTE
According to the key study (Richeux, 2017) conducted in accordance with the O.E.C.D. test guideline n° 423, the LD50 of
the test item is higher than 2000 mg/kg body weight by oral route in the rat.
DERMAL ROUTE
According to the key study (Richeux, 2017) conducted in accordance with the O.E.C.D. test guideline n°402, the LD50 of
the test item is higher than 2000 mg/kg body weight by dermal route in the rat.
INHALATION ROUTE
The pure substance is a paste. As a consequence, the study need not be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and the possibility of exposure to aerosols, particles or droplets of an inhalable size.

These observations were compared to historical control data. Clinical observations and mortality were recorded every day for 14 days.
- Periodical examinations: The animals were weighed on D0 (just before administering the test item) then on D2, D7 and D14. Weight changes were calculated and recorded.
- Examination at the end of the test: On D14, the animals were anesthetised with sodium pentobarbital (Dolethal). Macroscopic observations were entered on individual autopsy sheets. Only those organs likely to be modified in cases of acute toxicity were examined. No organ was removed and preserved in view to microscopic examinations. - Key result
