The ready biodegradability of the test item 2,3-Epoxypropyl
neodecanoate, oligomeric reaction products with toluene-4-sulfonic acid
was determined with a non adapted activated sludge over a test period of
28 days in the Modified Sturm Test according to OECD 301 B. The
biodegradation was calculated for each titration time. The percentage
degradation of the functional control reached the pass level of 60 %
after 6 days and a biodegradation of 88 % after 28 days. The
biodegradation of the reference item was not inhibited by the test item
in the toxicity control. Both test item replicates reached the 10 %
level (beginning of biodegradation) after 18 days and came to a
biodegradation of 13 % and 20 %, respectively, after 28 days. The test
item is considered as not readily biodegradable under test conditions.
Since the risk assessment showed that the risk for the use of the
substance is reasonably controlled there is no need to further
investigate the degradation potential for the substance.
