Description of key information

15708-41-5, EDTA-FeNa,
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-FeNa at a concentration of 1.02 g/L and at a temperature of 22.0 degrees C showed a value of 73.7 mN/m. This is nearly the same surface tension as water.

Key value for chemical safety assessment

Surface tension:
73.7
in mN/m at 20°C and concentration in mg/L:
