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.
