Sex:
female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Mortality:
no
Clinical signs:
0.5 - 4 hrs after dosing piloerection was noted in all 6 rats. In addition, all 6 rats showed a hunched posture 2 hrs after dosing. 6 hrs after dosing and from days 1-14 all rats were free of any abnormalities.

Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
The oral LD50 is > 2000 mg/kg bw
Executive summary:

The acute oral toxicity of the test item was examined in female Wistar rats in a study according to OECD Guideline 423 with GLP compliance. Apart from piloerection and hunched posture seen 0.5 - 4 hrs after dosing no other adverse effects were reported. The oral LD50 was > 2000 mg/kg bw.
