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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
PNEC values for the aquatic compartment have been derived using a combination of short-term toxicity data for the test substance and long-term data for structurally related substances (see IUCLID section 13 for read-across document).
For sediment and soil, no PNECs can be derived as not sufficient data is available. Based on the properties no adsorption of EDTA-FeHNa onto the sediment and soil has to be expected, thus the assessment of this compartment will be covered by the aquatic assessment and can be based on the pore water concentration only.
Conclusion on classification
By analogy with EDTA-FeNa (CAS 15708-41-5), EDTA-FeHNa is considered as not readily biodegradable. Based on its calculated log Kow (-10.6), it is not potentially bioaccumulable according to both criteria of DSD (Log Kow ≥ 3) and CLP (Log Kow ≥ 4). Short-term and chronic tests performed on the three trophic levels (i.e. fish, daphnids, algae) on the analogue EDTA-FeNa (CAS 15708-41-5) or other EDTA-complex indicate the substance EDTA-FeHNa is not considered as harmful to the aquatic environment after acute or prolonged exposure. As a result, EDTA-FeHNa is not classified regarding its environmental impacts, neither under the criteria of CLP, nor under those of DSD.
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.
