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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Stability:
Rapid photodegradation is expected in air. Whereas, in water a slow photodegradation is expected (DT50 = 190 d). Due to structural properties, hydrolysis is not expected to be a relevant process.
Biodegradation:
The results of the conducted degradation tests demonstrate that 4,4'-methylenedianiline is not readily biodegradable and not inherently biodegradable under domestic conditions, but it is removed from surface waters within days either by mineralisation or transformation and migration into sediment. Hence, the test substance itself is not considered to be persistent in the environment.
Bioaccumulation:
No bioaccumulation is expected based on an experimental study. BCF values ranging from <3.1 to 15 were found for Cyprinus carpio after 42 days exposure.
Adsorption/Desorption:
Binding to soild soil phase and/or organic matter is possible.
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.
