Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water solubility: 400-700 g/l at 20-25°C

Key value for chemical safety assessment

Additional information

Three secondary sources cite water solubilities for trisodium citrate in the range 400 -700 g/l at 20-25°; very limited information about the methods, test substances and results is available. The measured solubility of trisodium citrate will vary for the various anhydrous and hydrated forms of the substance. All results are consistent with trisodium citrate being very soluble in water and the available data are considered sufficient to fulfil the endpoint requirements.
