Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
There were no mortalities during the course of the study No
treatment-related clinical signs were recorded throughout
the treatment period in either sex. Body weigt and food
consumption were unaffected in any dose group in either sex.

Effects in organs:
Hematological investigations and clinical biochemistry did
not show changes of toxicological relevance at any dose
level in either sex. Mean terminal body weights revealed no
relevant changes when compared to controls. Decreased organ
weights of the pituitary in all male treatment groups in
comparison to control organs were not found to be of
toxicological relevance, because this change was not found
to be dose related and not associated with relevant
histopathological changes.
