Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: > 750 g/L (pure Choline bicarbonate)
Mischible in all proportions (75 % aqueous Choline bicarbonate solution)

Key value for chemical safety assessment

Water solubility:
750 g/L
at the temperature of:
20 °C

Additional information

Due to the instability of the anhydrous salt, the test substance is provided as high concentration aqueous solution (75 % w/v), which is a colourless liquid, and it can be therefore considered soluble in water in all proportions.

Knowing that the Choline bicarbonate is completely solved, as there is no visible precipitation in the 75 % (w/v) aqueous solution, the water solubility of Choline bicarbonate can be stated to be at least 750 g/L.
