Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Results of examinations

Details on results:
Clinical observations:
No systemic toxicity was observed in body weights or food
consumption.

Laboratory findings:
No real treatment-related trends occurred.

Effects in organs:
Statistically significant increases in relative liver
weights in the males were observed in the 500 and 1000 mg/kg
groups but no increases were seen in the absolute weights
and were thus considered to be biologically significant.


No histopathology occurred which was compound-related.
