Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
The substance did not induce a dose-related increase in the
number of revertant (His+) colonies in each of the four
tester strains (TA1535, TA1537, TA98 and TA100) and in the
number of revertant (Trp+) colonies in tester strain WP2uvrA
both in the absence and presence of S9-metabolic activation.
These results were confirmed in an independently repeated
experiment.


The compound was tested up to concentrations of 5000
µg/plate in the absence and presence of S9-mix. The
substance did not precipitate on the plates at this dose
level. The bacterial background lawn was not reduced at all
concentrations tested and no decrease in the number of
revertants was observed.
