Additional information

According to the study carried out by JME (2005), the test item is non readily biodegradable. However, no experimental details are provided.

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 89 % by exposure day 14, and reached an average biodegradation of 102 % 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 result is carried forward for the purposes of risk assessment and classification.
