Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The sorption behaviour of substances in soils or sewage sludge can be described through parameters experimentally determined by means of the test method C.18.
An important parameter is the adsorption coefficient which is defined as the ratio between the concentration of the substance in the soil/sludge and the concentration of the substance in the aqueous phase al adsorption equilibrium.
The adsorption coefficient normalised to the organic carbon content of the soil Koc is a useful indicator of the binding capacity of a chemical on organic matter of soil and sewage sludge and allows comparisons to be made between different chemicals.
The experimental method described in the test uses HPLC for the estimation of the adsorption coefficient Koc, as described in the C.19 test method.
Following the criteria reported in the method C19 "Estimation of the adsorption coefficient (Koc) on soil and on sewage sludge using HPLC", the sample of FEXO-03 presents a medium value in the adsorption scale.
[LogKoc: 2.63]
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
