Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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


Experimental data are available concerning the hydrolytic potential of Fe(Na)HBED. The interaction of iron chelates was determined at different pH values. In general, the test substance was found to build extremely stable complexes (Lucena et al., 2009).


Chojnacka (2010) conducted screening test according to OECD 302 B, concluding that the test substance is not inherently biodegradable. However, based on the intrinsic properties of Fe(Na)HBED and the usage as fertilizer, no further investigations in soil and water/sediment are intended (REACH, Annex IX, Section and Section, respectively).


No experimental data available. Based on the substance specific logPow of -1.96 (OECD 107, Guzik, 2011) and in accordance to REACH, Annex IX, Section 9.3.2., column 2, no experimental investigation is required, since bioaccumulation is not to be expected. The predicted BCF is 3.16 L/kg (Chemservice S.A., 2012).

Transport and distribution

Soil adsorption was experimentally investigated for Fe(Na)HBED by Lucena, López-Rayo and Hernández (2009) on the basis of OECD 106. A low soil reactivity was concluded for the test substance and displacement by other cations seems to be of low importance. Furthermore, it is able to maintain a significant amount of Fe in solution when interacting with soil for a longer time. The Koc is predicted as 67.13 L/kg (MCI method by KOCWIN v2.00). Based on the applicability in high pH soils, the substance can not be highly adsorptive to soil particles; since bound to particles, it would not be able to transfer nutrients (iron) to the plant roots.

Environmental data

Neither monitoring data nor field studies are available for Fe(Na)HBED. No investigation is intended since these are only optional endpoint for a registration under REACH at a tonnage band of 100 - 1000 t/a.
