Description of key information

According to the key ready biodegradability test (OECD Guideline 301F with GLP compliance, 2012), the registered substance attained 67.6 % biodegradation after 28 days of incubation. Therefore, the substance is readily biodegradable but does not fulfill the 10-day window criteria. From the graph 60% of biodegradation seems to be reached just after the 10-day window, on the 18th day of experiment (with the measurement just below 10% occurring on day 7). The second study (EU Method C.4 -E with GLP compliance, 2008) showed that 50 % of the registered substance biodegrades after 36 days and that the pass-level is almost reached, but the 10-day window criteria is not fulfilled either. As the substance was dissolved in a partially biodegradable solvent, it cannot be ascertained directly to what extent the chloroform degradaded in the solutions containing test substance. Consequently, the results of the study are not interpretable and the study is considered technically invalid.

In conclusion, according to the key biodegradation study (OECD Guideline 301F) the registered substance is readily biodegradable but does not fulfill the 10-day window criteria.
