Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Simon (2015) conducted a study following recent guidelines and in compliance with GLP. In the procedural controls, the reference substance sodium benzoate was degraded by an average of 85 % by exposure day 14, and reached an average biodegradation of 90 % by the end of the test (day 28), thus confirming suitability of the activated sludge. The biochemical oxygen demand of the test item in the test media was in the same range as the inoculum controls, so the test item exhibited no significant additional oxygen demand. Consequently, the test item was not biodegradable under the conditions of the test.

The study is considered complete, reliable and adequate. The results is carried forward for the purposes of risk assessment, classification and labelling.
