The ready biodegradability of Beta-Ionon was tested in two different
test systems. In a guideline study following EEC Directive 79-831 Annex
V, part C, 5.2 the O2 consumption of domestic activated sludge was
recorded during 28 days exposure to Beta-Ionon. A degradation rate of 70
– 80 % was recorded at test termination (BASF AG, 1989). Comparable
results were detected by a second study using predominantly domestic
sewage as inoculum. The test was set up in compliance with guideline ISO
14593 and 73 % degradation were reported for an inoculation time of 28
days (Brixham Environmental Laboratory, 2000).
Based on these studies, Beta-Ionon is assumed to be readily
