Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

logKOC = 4.9820 (worst case QSAR on representative theoretical hydrolysis product )

Key value for chemical safety assessment

Koc at 20 °C:
95 940

Additional information

Adsorption of the substance itself is not expected due to the fast hydrolysis after contact in water.

However, to consider the worst case, the calculated logKoc of 4.982 for the representative hydrolysis product (ASA T16 H) is used for risk assessment.
