Description of key information

The test substance was tested in an OECD 301 D . After 28 d no biodegradation (-3%) was observed, whereas after a test prolongation up to 60days a slight biodegradation activity of 10-20 % was observed. It is concluded that the test item is neither readily biodegradable nor inherently biodegradable under the chosen conditions.
Additional modelling using Biowin 1-6 by Biowin vs. 4.10 was performed with the test item to screen if the substance potentially fulfils criteria for PBT. In all 6 models the criteria for fast degradation were met.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
