Description of key information

OECD 111

The present study investigated the hydrolytic behaviour of the test item in aqueous solutions buffered at pH 4, 7 and 9 and at one elevated temperature. Samples were incubated in the dark. The test was carried out for 5 days. At the end of incubation, 99.6-100.3% of the nominal applied concentration were found and thus the test item can be stated as hydrolytically stable (t0.5 > 1 year at 25°C).


The test item was investigated for its ready biodegradability in a manometric respirometry test over a period of 28 days. The degradation rate of Acid Blue 182 never reached 60% within the 10-day window or after 28 days. Therefore, Acid Blue 182 is considered to be not readily biodegradable.
