Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The ability of the substance to adsorb to soil was investigated in a screening study in accordance with the standardised guidelines OECD 121 and EU Method C.19 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
The soil adsorption/desorption screening test was carried out using the HPLC estimation method at a column temperature of 30 °C in a mobile phase of methanol : reverse osmosis water (55:45 v/v). As the test material is a salt of a dicarboxylic acid, testing was performed at a neutral pH with the test material in its ionised form only. The adsorption coefficient (Koc) of the test material has been determined to be <17.8, logKoc <1.25. This low value is considered consistent with the low partition coefficient.
This value indicates a low potential for the substance to adsorb to soil/sediment and suggests high mobility in the environment.
As the screening study indicated a low potential for adsorption, no higher level testing for this endpoint has been proposed by the registrant
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
