Description of key information

The biodegradation potential of Orivone in water was determined in a screening study according to OECD TG 301D (Closed Bottle Test) and in compliance with GLP criteria (IFF, 2016). The test was performed according to slightly modified OECD, EU and ISO Test Guidelines: ammonium chloride was omitted from the medium to prevent oxygen consumption due to nitrification. In this study, 2 mg/L test substance was inoculated with river water for 28 days under aerobic conditions. At regular intervals throughout the incubation period the oxygen consumption was measured and compared to the ThOD as indication of biodegradation. The observed biodegradation percentages did not exceed 3%. Based on these findings the substance is classified as not readily biodegradable.
