- Executive summary:
Isobutyralacetate was tested for its ready biodegradability in the CO2 evolution test (Modified Sturm Test)
The study procedure was based on OECD guideline No. 301 B, July 17, 1992.
The test piece was added in a quantity of 20 mg/l DOC to the test medium.
The inoculum was derived from the secondary effluent of a treatment plant. Anillin was used as reference substance. The observed biodegradability was 19% after 28 days.
The criterion for ready biodegradability (at least 70% removal of DOC in a 10 -day window) was not met in these experiment.
The substance was found to be not readily biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
