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
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
As the screening study indicated a low
potential for adsorption, no higher level testing for this endpoint has
been proposed by the registrant
