Description of key information

BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) determinations were carried out for the test substance using the EU Method C.6 (Degradation, Chemical Oxygen Demand) cited as Directive 84/449/EEC, C.9 and EU Method C.5 (Degradation: Biochemical Oxygen Demand) cited as Directive 84/449/EEC, C.8. The study was carried out in accordance with the OECD principles of Good Laboratory Practice. 
The 5-day BOD value was found to be an average of 0.0069 grams of oxygen per gram of the test substance at percent concentrations of 0.020, 0.030, and 0.060. The 20-day BOD value was found to be an average of 0.011 grams of oxygen per gram of the test substance at percent concentrations of 0.020 and 0.030. The COD result is the mean of three measurements and was found to be 0.791 grams of COD per gram of the test substance. The test material is not readily biodegradable based on a BOD5/COD ratio less than 0.5. The BOD5/COD ratio was found to be 0.0087.
