Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Annex VII, Column 2 of the REACH Regulation (EC 1907/2006), the study does not need to be conducted if, based on the physicochemical properties, the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient).

Target substance has a low logPow, i.e. -0.3993 at pH 3.17 and 20 °C, indicating a low potential for adsorption.

The low adsorption potential was confirmed by prediction carried out by KOCWIN v2.00 as implemented by EPI Suite v4.11.

Experimental water solubility and logPow were used as input and predicted Koc of 25.31 l/kg and logKoc 1.403 were found.

Such values are indicative of a low adsorption potential. As reported in Chapter R.7b: in general substances with a Koc <500 – 1000 l/kg are not likely sorbed to sediment (SETAC 1993). According to this, a log Koc or log Kow of ≥3 is used as a trigger value for sediment effects assessment.
