Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Mackay fugacity modelling (level 1) indicates that, in the absence of degradation, more than 80% of the substance would end up in the water phase with the remainder in the soil phase. Insignificant amounts would remain in the air and sediment phases.
Executive summary:

Mackay fugacity modelling (level 1) indicates that, in the absence of degradation, more than 98% of the substance would end up in the water phase with the remainder in the soil phase. Insignificant amounts would remain in the air and sediment phases.
