Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 log Koc of the test substance in non-ionised form was determined to be log Koc = 3.3 (Koc=2000) and for the ionized form log Koc = 3.2 (Koc=1600). Taking into account the classification scheme of Blume & Ahlsdorf (1993), a high sorption onto soil organic matter has to be expected.

Additional information

The soil sorption coefficient log Kow (Koc) was determined in a study conducted according to OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC) 2001) and EU Method C.19 (Estimation of the Adsorption Coefficient (KOC) on Soil and Sewage Sludge Using High Performance Liquid Chromatography (HPLC) 2008).

Study data were conducted without GLP, however the criteria of REACH Annnex XI, section 1.1.1 are met and therefore data were valid for the endpoint being investigated.

Based on the results with the reference substances, the log Koc of the test substance in non-ionised form was determined to be log Koc = 3.3 (Koc=2000) and for the ionized form log Koc = 3.2 (Koc=1600). Based on the results and taking into account the classification scheme of Blume & Ahlsdorf (1993), a high sorption onto soil organic matter has to be expected.
