Additional information

Ready biodegradability has been determined with a non adapted activated sludge in the Modified Sturm test. The substance reached the 10% level (beginning of biodegradation) after 9 days. The test item did not reach the 60% pass level within the 10-day-window, but after 24 days. The substance is regarded, as a minimum, as inherently biodegradable and can be regarded as readily biodegradable though failing the 10 -day window criterium.

With adapted sludge, primary degradation in excess of 99% occurred over 28 days and ultimate degradation, measured as CO2 evolution, was 76% after 28 days.

In accordance with REACH Regulation 1907/2006/EC (Annex IX - 9.2.1.2, 9.2.1.3, 9.2.1.4 - column 2) simulation tests of biodegradation in water, sediment and soil do not need to be conducted.
