Description of key information

logKoc estimated= 3.39

Key value for chemical safety assessment

Koc at 20 °C:
2 487

Additional information

The LogKoc was estimated by using calculation software EpiSuite 4.1 based on a LogKow ca. 3.4 and water solubility <0.1 mg/l.

The based structure was the amide derivative and the results are Koc: 2487 and logKoc 3.39 (>3). Even though the value of the logKoc would trigger the testing for adsorption/desorption for characterising the partitioning between environmental compartments, Basic Brown 1 Acetate is expected to have a lower adsorption potential based on its greater polar characteristic with respect to its amide derivative.
