For the components of this UVCB substance adsorption to the solid soil phase and suspended particles is expected. Therefore, low mobility in soil can be assumed.
The Koc for this UVCB substance can not be determined experimentally due
to its low water solubility and because it is a reaction product
consisting of a variety of constituents. Therefore, it is not possible
to calculate a single Koc.
Therefore, the adsorption potential was estimated on the basis of the
Koc values of the representative constituents of this UVCB substance.
The calculated logKoc values derived with KOCwin v.2.00 for the C4, C8
mono-, di-and tri- alkylated diphenylamine derivatives range from
approximately 3.8 to 8.1 L/kg (BASF SE 2017).
LogKOC values derived with the logKow method, were not considered
relevant for structures with a logKow > 8 as the this log Kow lies out
of the applicability domain of the model.
