Sex:

male/female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Mortality:

None

Clinical signs:

other: No significant signs of toxicity except for transient rough fur and reduced activity direct after dosing

Gross pathology:

No macroscopic findings

Any other information on results incl. tables

The limit dose of 2000 mg/kg showed no mortality in male and female rats. Although only 2 animals per sex were tested, the observations do not indicate a toxic effect.
