Description of key information

The ready biodegradability of FAT 41043/A TE was investigated according to OECD Guideline 301 F, EU Method C.4-D and GLP principles (NOTOX study 498117). No biodegradation of FAT 41043/A TE was observed after 28 days.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

NOTOX study Nr. 498117:

FAT 41043/A TE was not ready biodegradable under the conditions of the 'Manometric Respirometry Test.

NOTOX study Nr. 497918:

Due to the physical chemical properties of FAT 41043/A TE, especially the limited solubility in water, performance of a Zahn-Wellens/EMPA test was not possible. NOTOX study Nr. 498116: According to the general principle of the BOD5 test a solution of FAT 41043/A TE of at least 2 mg/l in mineral medium should be inoculated and incubated under aerobic conditions in the dark or in diffuse light. Due to the physical chemical properties of FAT 41043/A TE, especially the limited solubility in water, performance of a BOD5 test was not possible. Therefore, it is not possible to perform the BOD5 test (EEC Directive 440/2008, Part C.5. 2008; ISO Standard 5815, 2003).
