Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
hydrolytically stable but readily biodegradable
Key value for chemical safety assessment
Additional information
In accordance with column 2 of REACH Annex VII, the study does not need to be performed if the substance is readily biodegradable or inorganic. N,N'-bis(3-aminopropyl)ethylenediamine is readily biodegradable. Therefore, a study is not required.
Nevertheless, in a read-across approach to the structurally similar substance triethylenetetramine dihydrochloride the hydrolytic stability was studied. The stability was determined after exposure of three concentrations (1, 100 and 200 g/L) exposed to light and at ambient temperature conditions. The recovery was greater 99% after 36 days. Therefore the substance was assessed to be hydrolytically stable in aqueous solutions (Hansen et al., 1985).
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.
