Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The determination of the water solubility for EDTA-NiH2 is performed by EPI Suite, WSKOW v1.42 which is an accepted programm for the calculation of this endpoint.

Due to the structural similarity it can be concluded that the water solubility of EDTA-Ni(NH4)2 will not be significantly different.

Furthermore, EDTA-Ni(NH4)2 is produced, distributed and used as aqueous solution. As the highly concentrated solution is the commercial form of the product it is known that the water solubility is known to be very high at standard conditions (>> 1g/L). No further study has to be conducted due to that reason.

Key value for chemical safety assessment

Water solubility:
1 g/L
at the temperature of:
25 °C
