Description of key information

The results of a biodegradation test, performed according to OECD 301C, showed 1% biodegradation based on BOD and 2% biodegradation based on test material analysis at 28 days. No peak was observed in the HPLC chromatograms from a degradation product.

From the results of the ready biodegradation test, it is observed that no degradation products are formed in 28 days. If this is observed in a study with sludge, certainly no degradation products are anticipated in water/sediment/soil.
As the substance is not classified, no exposure and risk assessments are needed and thus no further degradation testing is proposed. Furthermore, as the substance itself is experimentally determined not to bioaccumulate (BCF < 61 L/kg) and thus not B/vB, no further information is needed on the Persistency (in accordance with the PBT Guidance Figure 11.3, step 4 (further information needed if substance also potentially B)).

As the substance is not classified, not a PBT/vPvB substance (as it is not B/vB) and no degradation products are formed, no further simulation tests are necessary.
