Biodegradation in water:
readily biodegradable

Additional information

The biodegradation of the substance was evaluated according to the OECD guideline 301F. A measured volume of inoculated mineral medium, containing a known concentration of test substance (100 mg test substance/l) as the nominal sole source of organic carbon was incubated with the activated sludge for 28 days. The consumption of oxygen was determined and was expressed as a percentage of ThOD or Chemical Oxygen Demand (COD).

The test substance was considered as readily biodegradable as the removal of ThOD within 28 days is greater than 60 % and this pass value was reached in a 10 -day window.
