Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 partition coefficient log Pow is estimated to be 1.69-1.9.
Key value for chemical safety assessment
Additional information
Since the study is technically not feasible, there is no experimental data for partition coefficient.
The log Pow for four constituents (C12 linear and branched, C13 linear and branched) of this substance is estimated by using KOWWIN programme v1.67a, Estimation Programs Interface Suite™ for Microsoft® Windows v 4.00. US EPA as well as ACD Labs Software (log D). Due to the postulated equal distribution of 4 single chains in the composition, arithmetic means of four outcomes are taken as boundary values: 1.69 (ACD Labs) and 1.9 (KOWWIN). Thus, log Kow= 1.69 -1.90.
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).
