Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
Substance will primarily partition to the aqueous phase
Executive summary:

Mackay fugacity modelling (level 1) indicates that, in the absence of degradation, virtually all of the substance (>98%) would partition to the aqueous phase. Of the remaining amount, this is partitioned approximately 2:1 between the air and soil.
