Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A maximum Koc value of 1.0E+06 L/kg is used in the assessment.

Key value for chemical safety assessment

Koc at 20 °C:
1 000 000

Additional information

No adsorption/desorption study is available for zinc bis(dibenzyldithiocarbamate). Therefore, the Koc was calculated with KOCWIN™ (U. S. EPA, 2008) using the Molecular Connectivity Index as zinc bis(dibenzyldithiocarbamate) is an ionic substance (for details see QMRF and QPRF as attached to the respective IUCLID entry and CSR Appendix A.2). The calculated Koc value is 2.6E+09 L/kg. A maximum Koc value of 1.0E+06 L/kg is used in the assessment.
