Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

In a guideline study, to GLP, celery ketone (at 30 mg/l) was not readily biodegradable (0% at 28 days) in activated sludge.

Key value for chemical safety assessment

Additional information

In a guideline 301F ready biodegradability test, conducted according to GLP, celery ketone (at 30 mg/l) achieved 0% biodegradation at 28 days. Thus, celery ketone should be regarded as not readily biodegradable under the conditions of this test.

In a guideline 302C inherent biodegradability test, conducted according to GLP, celery ketone achieved no biodegradation after 28 days, 41% after 60 days and 66% after 90 days. When assessing inherent biodegradability it is not necessary to define limits on test duration. Biodegradation above 20% may be regarded as evidence of inherent, primary biodegradation, whereas biodegradation above 70% may be regarded as evidence of inherent, ultimate biodegradability. Thus celery ketone should be regarded as inherently primarily biodegradable according to this test. Given that a level of 66% biodegradation was achieved indicates that the substance is not expected to be persistent in the environment.
