Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
EPIsuite (KOCWIN v2.00) QSAR predicted the fpollowing log Koc values:
Estimate from MCI: 0.404
Estimate from Log Kow: 0.0826
These are highly consistent with the hydrophilic nature of the test item.
