Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The calculated log Koc values for substances in this category range from 2.07 - 5.365.

Key value for chemical safety assessment

Additional information

As these are poorly soluble UVCB substances it is extremely difficult to measure a Koc value experimentally. The Koc for these substances has therefore been calculated based on a measured Kow value, following the equation in the EU Technical Guidance Document (2003) and the ECHA Guidance Document R7a (2008): log Koc = 0.81 Log Kow + 0.1.
