Description of key information

The test item must be regarded to be not readily biodegradable after 28 days. No primary biodegradation/elimination was determined at test end in a study according OECD 301 C.
Based on the residue analysis, biodegradation of the test substance was 30.8% in the “test” vessel during the testing period. The BOD results showed that biodegradation of the test substance was 41.2% after 28 days in an inherent study according OECD 302 C.
Therefore under the test conditions of both studies (OECD 301C and OECD 302C) the pass level was not reached. The test substance is not readily biodegradable and not inherently biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
