Description of key information

Biodegradation degree: <10% CO2/ThCO2 after an exposure period of 28 days (mean value from two test assays)
Sudan Marker 455 was poorly biodegradable under the conditions of this test. Evaluation in accordance to criteria of the OECD Test Guideline:
Sudan Marker 455 was not readily biodegradable under the conditions of this test.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
