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.
