Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 to soil was estimated by using the Estimation Programs Interface Suite™ for Microsoft® Windows, v 4.10. United States Environmental Protection Agency, Washington, DC, USA. The adsorption to soil was separately calculated with KocMin v.2.00 for the components of the target substance. The MCI method resulted a Koc value from 8.412 to 16.4 L/kg. The log Kow based method resulted a Koc ranging from 0.03356 to 0.62 L/kg. The value calculated with the MCI method for the main constituent  (tetramethylammonium hypochlorite) was selected as a key value.

Additional information

The target substance is a multi-constituent substance. The estimated Koc-values were calculated with KOWWIN v.2.00 estimation tool (US EPA 2014). The highest estimated adsorption coefficient value by using the MCI method for the main constituent of the target substance (tetramethylammonium hypochlorite) was selected as a key value for CSA.
