Description of key information

Adsorption to solid soil phase is expected.

Key value for chemical safety assessment

Additional information

Experimental data are not available. A study on the adsorption of the substance was not accomplishable due to the physico-chemical properties of the substance. However, the molecular structure and physio-chemical properties of the substance indicate that an adsorption of the substance to organic surfaces can be expected. This assumption is supported by calculated log KOC values of 9.95 for compound 1 and 19.85 for compound 2 of Tinuvin 123, respectively (KOCWIN Program (v2.00)).
