Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 study was conducted according to OECD Guideline 121, Estimation of the Adsorption Coefficient (KOC) on Soil and on Sewage Sludge using high performance liquid chromatography (HPLC).
At pH values of 2 and 10, the kâ for phenol, dodecyl-, sulfurized, carbonates, calcium salts, overbased could not be calculated for both the 5.0 and 10 mg L-1 test concentrations. This was because there were no substantial sample peaks observed in any of the chromatograms. It has been demonstrated that the test substance has a chromophore and therefore is assumed to have been retained on the column and has been assigned a log10 KOC value of >5.0.
Key value for chemical safety assessment
Additional information
The key study for this endpoint is considered to have a reliability rating of 1, however the study is being used as read across to a structurally similar substance (EC 701 -251 -5) as there was no available data to fulfil this endpoint for the test material and so the reliability rating will be reduced to 2, according to the criteria of Klimisch, 1997.
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.
