Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 water solubility of EDTA-ZnNa2 is at least 534 g/L at 0°C.

Key value for chemical safety assessment

Water solubility:
534 g/L
at the temperature of:
0 °C

Additional information

This is supported by an earlier study: 14025-21-9, Water solubility, Van den Berg, 1993, SS:

The water solubility of EDTA-ZnNa2 is at least 44% w/w at 30°C.

Since the water solubility is very high the accuracy of the data and the purity by current product specification is considered to be sufficient.

This determination has sufficient reliability for environmental risk assesment purposes.
