Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Estimated based on solubility ratio:

Log Pow= >4.2 at 20°C

Key value for chemical safety assessment

Additional information

Due to the fact that the test item shows different water soluble amounts, depending on the elements analyzed and methods applied and the differences between the sample sizes 0.1 g/L and 1.0 g/L (in case of TOC) the test item does not show a water solubility as a whole but contains different fractions with different water solubilities

Because of that it was not possible to estimate a general valid log Pow value. The log Pow values also depends on the method applied and the sample size.

The log Pow values were estimated based on the individual solubilities at 20°C and the results are as follows:

logPow= > 5.1 with the water solubilities by cobalt content at loading rate of 0.1 and 1.0 g/L

logPow = 4.9 with the water solubilities by TOC at loading rate of 0.1 g/L

logPow = 4.2 with the water solubilities by TOC at loading rate of 1.0 g/L

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
