Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a good quality, based on OECD Guideline 106 and to GLP, an overall mean log Koc value of 5.3 (Koc = 199,526 l/kg) was derived for a C10 and for a radiolabelled C13 chlorinated paraffin (55% chlorination) in soil and sediment (Thompson et al. 1998).
Key value for chemical safety assessment
Additional information
In a GLP study based on OECD Guideline 106 (with modifications due to the low solubility of the test materials and difficulties with analysis), log Koc values were determined for a C10 and a radiolabelled C13 chlorinated paraffin (both 55% chlorination) with repsect of soil and sediment by batch equilibrium experiments. For both test substances, irrespective of whether the treatment was to a soil or to sediment, log Koc values of approximately 5.3 were derived. Close similarity of the log Koc values for the test substances suggest an overall mean log Koc of 5.3 (koc of 199,526 l/kg) can be used for SCCPs chlorinated to 55% by weight (Thompson et al. 1998).
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.
