Key result
Sex:
male/female
Dose descriptor:
LD50
Effect level:
> 2 009 mg/kg bw
Based on:
test mat.
Mortality:
No mortality was observed
Clinical signs:
There were no changes in behaviour or clinical signs in any of the treated animals during the observation period
Body weight:
Body weight changes in the treated animals were not influenced by treatment
Gross pathology:
There were no macroscopic findings that could be associated with treatment

Applicant's summary and conclusion

Interpretation of results:
Category 1 based on GHS criteria
Conclusions:
From the results obtained under the experimentals conditions employed, the LD50 can be expressed as follow:
LD50, by the oral route, in the rat (male + female) > 2009 mg/kg
Executive summary:

LD50, by the oral route, in the rat (male + female) > 2009 mg/kg
