Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The US EPA EPI Suite (v3.12) program (US EPA 2000) was used to estimate the sediment partition coefficient (Koc) or log Koc in order to assess the adsorption/desorption potential, The main components (e.g., C20-C22) in the registered substance have calculated log Koc values ranging from 5.81 to 6.37. Based on these findings, the registered substance and its main components or constituents have the potential to significantly adsorb to organic matter in sediment.
Key value for chemical safety assessment
Additional information
The US EPA EPI Suite (v3.12) program(US EPA 2000) was used to estimate the sediment partition coefficient (Koc) or log Koc of the C18 to C24 components in order to assess the overall adsorption/desorption potential of the registered substance (the reaction products of 1-decene, 1-dodecene, and 1-octene, hydrogenated).
The calculated log Koc values for the C18-C24 components were:
C18 H38 log Koc = 5.28-5.31
C20H42 log Koc = 5.81-5.84
C22H46 log Koc = 6.37
C24H50 log Koc = 6.90
Registrant's comments: The US EPA EPI-Suite modeling program has been extensively used in the OECD SIDS and the US EPA High Production Volume (HPV) programs and more importantly, the US EPI-Suite program is an integrated predictive tool in the OECD Toolbox to calculate physico-chemical and environmental fate properties for chemicals. Hence, the need to supply QMRF and QPRF for commonly applied EPI-Suite models is not warranted given its already accepted use in global regulatory notifications and its integration and underpinning in the OECD Toolbox for REACH
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.
