Description of key information

Additional information

In a test for ready biodegradability of the submission substance according to EU-method C.4-A and OECD 301A ("DOC Die-Away Test") and performed compliant to GLP (reliability category 1), the following results had been achieved:

19% biodegradation within 28 days (18% and 20% for the replicate samples) for the submission substance.

No inhibition of the submission substance on activated sludge microorganisms was observed at a test concentration of 86 mg/L.

The positive control sample was degraded by 98% within 3 days, proving the functionality of the test system.

Therefore, the submission substance proved to be biodegradable to some extent but failed the criteria for ready biodegradability.

Further tests on biodegradability (simulation tests) have not been performed as no further relevant information could be expected from additional testing (waiving according to "column 2" in Annex IX of REGULATION (EC) No 1907/2006).
