Description of key information

In a study using the equilibrium method performed according to OECD 106, the substance showed limited, but irreversible adsorption to soil. The logKoc was determined to be 2.06 -2.70.

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

The value used for risk assessment is the average of the 3 values found in the test according to OECD 106. As in two other soil types no adsorption (<10%) was found, the value of 2.5 is expected to represent a worst case for the adsorption characteristics of the substance.

In addition the substance is a UVCB and it cannot be excluded that specific components exhibit a different adsorption/desorption behaviour.
