Description of key information

In accordance to 7.8 of REACH Annex VII, the partition coefficient does not need to be conducted because the substance is inorganic.
As read-across from supporting substances three different logPow have been calculated using KOWWIN v. 1.67a from US EPA.

Key value for chemical safety assessment

Log Kow (Log Pow):
-2.4
at the temperature of:
20 °C
