Description of key information

The substance is not biodegradable in tests on the ready and inherent biodegradability.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The ready biodegradability and the inherent biodegradability of the test item FAT 40850/A TE were tested in two valid GLP studies according to EU Methods C.4-D and C.9, respectively. The substance did not fulfil the criteria for a readily biodegradable substance, but showed a certain potential for biodegradation under the test conditions since about 13% of the substance was found to be degraded after a period of 28 days. The potential for biodegradation could not be confirmed in the Zahn-Wellens test on inherent biodegradability and the substance was considered as not inherently biodegradable. It can be concluded that FAT 40850/A TE is not biodegradable.
