Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 coefficient for soil or sewage sludge could not be experimentally determind by the HPLC method. Therefore, the Koc was estimated at 4.913 L/kg  by using the U.S. Environmental Protection Agency EPI Suite KOCwin v2.00 Program.

Additional information

The adsorption coefficient for soil or sewage sludge could not be experimentally determined by the HPLC method. Therefore, QSAR modeling utilizing EpiSuite version 4.10, from the U.S. Environmental Protection Agency (EPA), a validated QSAR program which is part of the OECD (Q)SAR Toolbox was used to calculate an adsorption coefficient for Polycat 9. The Log Koc for Polycat 9 was estimated at 0.6913 and the Koc was estimated at 4.913 L/kg by using the U.S. Environmental Protection Agency EPI Suite Program. This suggests that Polycat 9 exhibits low sorption onto soil and sediment.
