Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Log Koc for the environmentally relevant constituent of the UVCB test item was predicted to be 5.14 (KOWWIN v1.68).

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C

Additional information

Experimental determination of partition coefficient was not possible because the test item is a complex, surface active, UVCB where the components exist as ion pairs. Log Kow for the environmentally relevant constituent of the test item was therefore predicted using EPISUITE (KOWWIN v1.68). The Log Kow calculated was 5.14.
