Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The adsorption coefficient Koc of the Similar subtance 2 on soil and sewage sludge was tested following Method C.19, Estimation of the adsorption coefficient (Koc) on soil and sewage sludge was performed using high performance liquid chromatography (HPLC) at pH 5.6 and 7.4. The mobile phase were citric buffer solutions since the tested substance is ionisable. The temperature was set at 25°C.
In the Sbovodova study (Sbovodova, 2012) using the HPLC method, the test substance DBk22 eluted rapidly, in fact elution was faster than the standard used to determine the dead-time. Therefore using the HPLC method was determined to be unsuitable for the determination of the Koc of DBk22 and the result on the similar substance 2 has been taken as a reference for risk assessment
Therefore no soil adsorption is expected
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
