Description of key information

In a OECD301F (manometric) study with 9% mineralisation at 28 days was observed. In three inherent tests, mineralisation was ranging  from 20-36% after 28 days.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Biodegradation screening tests in water are available for NLP3 a structural analogue of CAS 102-60-3.

In an OECD 301F (manometric ready biodegradability) study with NLP3 9% mineralisation after 28 days was observed based on oxygen consumption (Bayer, 1993). NLP3 exhibited inherent (primary) biodegradability in OECD 302/302B, EU C.4.D/C.9; mineralisation was ranging from 20 -36% after 28 days based on DOC removal (Bayer AG, 2002).

Comparable degradation rates are expected for Ethylenediamine, +4PO und thus the substance is expected to be inherent (primary) biodegradable, and it is therefore not expected to persist indefinitely in the environment.
