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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ecotoxicological Summary
Administrative data
Hazard for aquatic organisms
Hazard for air
Hazard for terrestrial organisms
Hazard for predators
Additional information
EDTMP salts will fully dissociate in aqueous solution at concentrations relevant for environmental assessment, and will behave no differently to the parent EDTMP acid and its counter ions at equivalent concentrations. It is not expected that the counter ions (H+, Na+and Ca2 +) will contribute significantly to the overall toxicity of the substance. Therefore, the impact on aquatic, sediment and terrestrial organisms will be dominated by the effects of EDTMP acid and the environmental hazard assessment will be based on the acid form of the substances in this category.
Conclusion on classification
The substance is not classified for the environment according to Regulation (EC) No. 1272/2008/EC because short-term toxicity data report EC/LC50 values >100 mg/L and even though the substance is not readily biodegradable, the log Kow of the substance is -4.1.
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.
