Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 this endpoint can be waived. No hydrofobic tail is present. Moreover, measurement of the surface tension of an aqueous solution of PDTA-Fe(NH4) at a concentration of 1 g/L and at a temperature of 20 degrees C showed a value of 73.2 mN/m. This is nearly the same surface tension as water, viz. 72.3 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 73.2
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
No surface active properties are expected, because of the absence of a hydrophobic tail in the structure.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
