Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

According to column 2 of Annex VIII of the REACH Regulation (EC 1907/2006), the study on adsorption/desorption does not to be conducted if the physicochemical properties of the test item indicate low adsorpton potential, such as a low octanol/water partition coefficient. As test item has a log Kow < 0 and a high water solubility, it can be concluded that the substance has a low adsorption potential and the study on adsorption/desorption is not run.

A default value for Koc of non-hydrophobic substances is proposed by EUSES 2.2.0; this value is 3.162 l/kg and it is used in the chemical safety assessment.
