Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adsorption / desorption

The adsorption coefficient (Koc) on soil and on sewage sludge using high performance liquid chromatography (HPLC) has been estimated andadsorption coefficients estimated to be log Koc,soil = 21.41 and log Koc, sewage sludge = 23.21. These values correspond to a Koc,soil = 2.582E21 and Koc,sewage sludge = 1.642E23. The McCall classification scheme classifies the substance as immobile in soil (Koc > 5000).

Henry's Law constant

The Henry's Law constant was estimated using the software HENRYWIN (v3.20). The value of 6.69 Pa m³/mol indicates that the substance is moderately volatile from surface water.

Distribution modelling

Distribution in environmental compartments was calculated using a Fugacity model according to Mackay, Level III. Distribution in various environmental compartments is estimated as: Air - 0.413%; Water - 3.5%; Soil - 27.2% and Sediment - 68.9%.

Sediment and soil are therefore considered to be the major target compartments.
