Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Based on the molecular structure the endpoint can be waived. No hydrofobic tail is present. Moreover,  measurement of the surface tension of an aqueous solution of EDTA-MnNa2 at a concentration of 1.04 g/L and at a temperature of 22.0 degrees C showed a value of 72.7 mN/m. This is nearly the same surface tension as water.

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 040
