Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 estimated Koc of the mono- and di-condensation product of 400112 are both higher than 1000. Therefore adsorption of this substance is very likely.
Key value for chemical safety assessment
Additional information
The study was technically not possible as no suitable analytical method could be established for this surface active UVCB substance.
The calculated Koc of the mono-condensation product of 400112 is 1.252e+005 L/kg based on the first-order Molecular Connectivity Index (MCI) or 4.002e+004 L/kg based on the estimated log Kow of 7.51 (KOCWIN version 2.00 estimate). The calculated Koc of the di-condensation product is even higher (1.328e+009 L/kg based on MCI or 3.544e+008 L/kg based on the estimated log Kow of 14.81).
As both Kocs are higher than 1000 adsorption of this substance is very likely.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.
