Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The adsorption/desorption coefficient was estimated by using KOCWIN v2.00 from EPI SUITE 2000 (U.S. Environmental Protection Agency). The methods applied produced the following values: 3.45 for the MCI method and 4.39 from method using log Kow value (6.5).

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

The highest log Koc value (4.39) was used for chemical safety assessment (CSA) and for the derivation of Predicted No-Effect Concentrations (PNEC) in sediments and soil.

This value was considered as a worst-case value, as an increase in the adsorption/desorption coefficient value leads to a significant increase of the PEC soil value.
