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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
1. Appearance / physical state / color
The test substance is a brown microgranulate with sweetish odour (at room temperature).
2. Melting point
A gradual partially decomposition of the test item starts with the melting process at 250°C.
3. Boiling point
This study does not need to be conducted since the substance decomposes before boiling [decomposition temp. > 250 °C].
4. Density
The bulk density of the test substance was determined to be 769 kg/m3 at 20°C.
5. Granulometry
The results of the dry sieving test of are presented in the table below:
| Sieve Aperture | % of fraction |
| > 2.0 mm | 15 |
| 1.5 - 2.0 mm | 15 |
| 1.0 - 1.5 mm | 20 |
| 0.3 - 1.0 mm | 45 |
| 0.1 - 0.3 mm | 5 |
| < 0.1 mm | 0 |
6. Vapour pressure
At 20 °C the determined vapour pressure was 5.75x10-4Pa, at 25 °C it was 7.76x10-4Pa.
7. Partition coefficient
The logPow was determined to be -1.96 at 25°C.
8. Water solubility
The substance is very soluble in water, at 20°C following results for the water solubility as a function of pH have been obtained:
34.55 g/L with distilled water at pH 5.4;
15.68 g/L with buffer solution at pH 4.0;
18.02 g/L with buffer solution at pH 7.0;
28.45 g/L with buffer solution at pH 10.0.
9. Surface tension
This study does not need to be conducted, as surface activity is not a desired property of the material.
10. Flash point
This study does not need to be conducted based on the physical state of the substance (solid). According to ECHA guidance, flash point is only relevant to substances that are liquid at room temperature.
11. Auto flammability
The relative self-ignition temperature has been determined to be 212 °C.
12. Flammability
The test item was not flammable under the conditions of the test.
13. Explosiveness
The test item was not expolsive under the conditions of the test.
14. Oxidising properties
The test item has no oxidising properties under the conditions of the test.
15. Stability in organic solvents and identity of relevant degradation products
The study does not need to be conducted as the stability of the substance is not considered as critical. The substance is applied only in water solutions (recommended use).
16. Dissociation constant
A stability constant of 39.01 for FeHBED, which was based on the protonation constant of the chelating agent HBED by potentiometric, spectrophotometric methods in KCl supporting electrolyte (0.100 M) at 25.0 °C and calculation programs, was confirmed.
17. Viscosity
This study does not need to be performed as the substance is a solid and viscosity measurement is only relevant to liquids.
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).
