Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Validity criteria fulfilled:
yes
Conclusions:
Applying the MCI method of the QSAR model KOCWIN v2.00 implemented in EPIWIN v4.1 the KOC of all the main organic moeities of the registered substances was 1 L/kg (logKoc = 0 L/kg).
Executive summary:

The KOC of the registered substance was calculated by QSAR for the main organic constituents. Applying the MCI method of the QSAR model KOCWIN v2.00 implemented in EPIWIN v4.1 the KOC of all the main organic moeities of the registered substances was 1 L/kg (logKoc = 0 L/kg).
