Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No dissociation predicted due to the fact that a dissociation constant could not be calculated because no dissociation could be measured at 20 °C with a read-across substance in the category.

Key value for chemical safety assessment

Additional information

No conductivity could be measured which was ascribable on dissociated parts of the test item of the read-across substance.

The very low conductivity measured in the sample solution was caused by impurites (ions of the elements magnesium, sodium and sulfur (sulfate)).

Due to this fact the calculation of the dissociation constant was not possible.
