Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

L-Threonine mother liquor is only partly soluble in water
water soluble part: 396-490 g/L ;
water insoluble part: 406-856 g/L at 20°C and initial test substance concentrations of 40.1 and 67.3 g/50 mL

Key value for chemical safety assessment

Additional information

The determination of the water solubility according to EU Method A.6 and OECD Guideline 105 was not successful due to the fact that L-threonine mother liquor has a complex compostion with individual water solubilities of the separate components. Therefore, the equilibrium method according to REACH Chapter R.7a was used.
