Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Ethylenediamine is a liquid with moderate vapor pressure (13 hPa at 20 °C). A calculated Henry's law constant of 0.6 Pa-m3/mole, giving a partitioning coefficient air/water of 3.2 x 10-3 at 25°C suggests that volatilisation from water is low.
The substance has a very low octanol-water partition coefficient (log Kow = -1.6), which also indicates a low potential for uptake in aquatic organisms. The amino groups in ethylenediamine will be present as charged species (cationic) under the pH conditions encountered in the environment.
Based on an adsorption-desoprtion study, ethylenediamine is likely to sorb strongly to soil. The adsorption potential is more related to the cation-exchange capacity of the soil than to organic matter content.
The substance is not susceptible to hydrolysis or direct photolysis in the aquatic environment.
From the experimental ready biodegradation assay in water, the substance was assessed to be readily biodegradable. Therefore, biodegradation is anticipated to be the major contributing factor for the removal of the substance from the environment.
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.
