Description of key information

The substance is classified as "not ready biodegradable". The substance exhibits inherent (primary) biodegradability, and therefore is not expected to persist indefinitely in the environment.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable, not fulfilling specific criteria

Additional information

Biodegradation in water was tested in two screening studies according to OECD 301F (ready biodegradability) and OECD 302B (inherent biodegradability). Diaminotoluene, propoxylated showed 23% biodegradability in the first test (Bayer, 2002) and 9% biodegradability in the second test (ISOPA, 2003) . In the OECD302B test, 22% degradation was observed after 27 days. The substance is classified as "not ready biodegradable". The substance exhibits inherent (primary) biodegradability, and therefore is not expected to persist indefinitely in the environment.
