Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biotic degradation
Fe (III) IDHAwas identified to be "readilybiodegradable"in OECD screening test 301F(BAYER AG, 2003). In addition to that, the substance was found to be biodegradableacc. to OECD Guideline 302 B - Inherent Biodegradability. Method: Zahn-Wellens/EMPA-Test.
Conclusively, thesubstance will be degraded when entering the environmental compartment and therefore will not be persistent.
Bioaccumulation
Bioaccumulation in aquatic organisms is not expected for Fe(III)IDHA. The first indication for that conclusion is given by the substance specific logPow of -7.51 at 25 °C (calculated; ADOB, 2016). Bioaccumulation is expected for substances possessing a partition coefficient in the range of 4.5 to 6 according to ECHA Guidance R.11, PBT Assessment).
Transport and distribution
Soil adsorption is not expected for Fe(III)IDHA based on the intrinsic physico-chemical properties, i.e. logPow of -7.51 (ADOB, 2016).
The QSAR prediction with KOCWIN v2.00 (logKoc = 1.00 L/kg; ADOB., 2016) reveals that the substance possesses no strong binding capacity towards soil.
Henry´s Law constant was calculated by EPI Suite program (HENRYWIN v3.20) and amounts to 9.027E-019 Pa-m3/mole at 25 °C (ADOB, 2016). This value, as well as the key value of the Koc determination, will be taken into account for the chemical safety assessment (CSA), i.e. PNECsediment and PNECsoil derivation via the equilibrium partitioning method (EPM).
Additional information
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.
