Additional information

Based on the physicochemical properties the substance is expected to have a low potential for adsorption; it is characterized by a negative octanol water partition coefficient, due to the high capability to dissolve in water phase.

Nevertheless, the Koc and the partition coefficients necessary for the PNECs calculation (PNEC sediment freshwater, PNEC sediment marine and PNEC soil) were estimated using the EUSES 2.1.2 tool*.

Suspended matter-water partition coefficient: 0.924

Soil-water partition coefficient: 0.229
