readily biodegradable (OECD TG 301 F)

Additional information

In a study conducted according to OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test) the following results were obtained:

The reference substance sodium acetate reached the pass-level (biodegradation>60%) already after 2 d. According to the results obtained in the toxicity control Amphopropionates C12 -18 (40% a.i.) is not inhibitory to the inoculum in the concentration used in the test (100% biodegradation after 14 d). The test item (test concentration: 70 mg/L corresponding to COD=89.6 mg O2/L) proved to be readily biodegradable and fulfilling the 10-d window criterion (71% biodegradation after 28 d; the 10% level was reached after 3 d and the 60% pass level after 12 d).

As the substance was demonstrated to be readily biodegradable, no further testing (Simulation testing on ultimate degradation in surface water, Soil simulation testing) is required in accordance with REACh regulation, Annex IX, 9.2.1, column 2.
