Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Adsorption / desorption
The adsorption coefficient Koc in soil and in sewage sludge of test chemical was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 121 for testing of Chemicals. The study was performed at a temperature of 23°C and pH 4-10, respectively. . Each of the reference substance and test substance were were analysed by Modular HPLC system with UV/Vis detector. Acetonitrile was used as a mobile phase. 5µl of test chemical was introduced in the column. The dead time of the HPLC system was measure with formamide. The reference substance used for the study were formamide, methyl benzoate, naphthalene, methiocarb, pyrazophos, alpha-endosulfan, diclofo-methyl and DDT, respectively. The Log Koc value of test chemical was determined to be > 5.63 dimensionless at 23°C. This log Koc value indicates that the substance has a very strong sorption to soil and sediment and therefore have negligible migration potential to ground water.

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.
