Executive summary:

Study design

The test material was tested for acute toxicity in rats after single oral administration of 2000 mg/kg body weight. The study was performed according to the OECD Guideline for Testing of Chemicals, No. 423.

Results

No signs of toxicity were seen in the rats (3 males, 3 females) after treatment with 2000 mg/kg of the test item.
The body weight development of the rats was inconspicuous during the study.
There were no deaths during the course of the study.
The gross pathological examination revealed no organ alterations.

Conclusion

Based on the result of this study, it is concluded that the test material has no acute toxic potential and that the LD50value is higher than 2000 mg/kg after single oral administration in rats.
