Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
On the basis of the available data, formaldehyde, reaction products with ethylenediamine, if released into the environment, will mainly distribute into the aquatic compartment (i. e. saltwater), where it is expected to biodegrade of 70% in 20 days. Hydrolysis is not expected to be a relevant removal pathway. In the aquatic environment, the substance is not expected to bioaccumulate in the aquatic organisms because of the low predicted BCF (1,41 L/kg ww) and logPOW(-2). The logKoc for formaldehyde, reaction products with ethylenediamine is > 5 at pH 3.5 and < 1.5 at pH 9.5 and the pKa is 8.18. If released in sea, formaldehyde, reaction products with ethylenediamine has a low tendency to bind to sediment, because the seawater pH is about 8 and the logKoc value is expected to be near 1.5, while, if release in soil, formaldehyde, reaction products with ethylenediamine is expected to have a low to high mobility, depending on the soil pH. If released in the atmosphere, formaldehyde, reaction products with ethylenediamine may be present, at a moderate extent, as vapour, basing on a vapour pressure of 2,176 Pa at 20°C (water: 3,200 Pa at 25°C).
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.
