Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information on results:
Observations:
No toxicity was observed in CHO cells when heated for 4
hours in the absence or presence of S9-action regardless of
dose level.The percentage of cells with structural and
numerical aberrations in the test article-treated group was
not significantly increased above that of the solvent
control.
The positive and solvent controls fulfilled the requirements
for a valid test.
The positive controls, cyclophosphamide and mytomycin C,
induced a significant increase in the frequency of
aberrations. Negative control values were within the normal
range
