Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 deaths and no clinical signs of toxicity were observed.

Laboratory findings:

The following haematological and biochemical changes were generally within the historical control range nad thus of doubtful toxicological significance /the test laboratory discounted the findings)

In the top dose males, statistically significant decreases were seen in neutrophils and platelets, with a dose dependent trend at other doses. Cholesterol levels, were lower in top dose males and females, and in intermediate dose males, compared to concurrent controls, reaching statistical significance in male of both dose groups. Decreased ALT in top dose females ans decreased phosphorus in top dose males was also noted.

Effects in organs:
At the top dose, slight increases inrelative organ weights (<20%) were noted for the liver and kidney in both sexes. Minimal centrilobular hepatocyte vacuolation was noted in two to dose males, but this was not considered to be of toxicological signifcance.
