Additional information


Two studies with validity 3 according to Klimisch were available. As the LD50 in rat was in the range from 3600 to 8500 mg/kg, no key study was chosen and a "Weight of Evidence" approach was applied.


Only one unpublished study from RIFM was available. As it was with validity 3, no purpose flag was chosen. The result gave a LD50 above 5000 mg/kg.
