Description of key information

No adsorption desorption studies are available for Distilled tall oil, maleated. However, a measured Kow value is available and this has been used to calculate the Koc value for Distilled tall oil, maleated.
The Koc value for this substance was calculated to be >43651.58 (log Koc >4.64) based on a measured log Kow value of >5.6.

Key value for chemical safety assessment

Additional information

No adsorption desorption studies are available for Distilled tall oil, maleated.

As Distilled tall oil, maleated is a poorly soluble UVCB substance it is extremely difficult to measure a Koc value experimentally. The Koc for this substance 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.

The Koc value for this substance was calculated to be >43651.58 (log Koc >4.64) based on a measured log Kow value of >5.6.
