Description of key information

Based on the components of the multi-constituent substance adsorption on the solid soil phase is possible.

Key value for chemical safety assessment

Additional information

Since Tinuvin 292 is a multi-constituent substance consisting of two components a single Koc value cannot be defined. Therefore, the adsorption potential was estimated separately for the two components by EPIWIN calculations. For the first substance (CAS 41556-26-7) a Koc value of 204400 (corresponding log Koc = 5.31) was determined. For the second substance (CAS 82919-37-7) a Koc value of 4726 (corresponding log Koc 3.67) was calculated [BASF SE 2010].
