Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ready biodegradability
The carbon dioxide evolution test (former Sturm test) is a static method to evaluate the ultimate aerobic biodegradability of a test substance in water. The test substance, a defined inorganic medium and a non pre-adapted inoculum (e.g. activated sludge or effluent of a municipal waste water treatment plant) were incubated and aerated at up to 28 days. The biologically produced carbon dioxide is trapped and measured. The biodegradation degree is expressed as produced carbon dioxide in relation to the calculated theoretical carbon dioxide value (ThCO2) using the initial concentration of total organic carbon of the test substance (TOC).
Biodegradation degree: 50-60 % CO2/ThCO2 after an exposure period of 28 days (mean value from two single test assays). The test substance was partly or moderately biodegradable under the conditions of this test.
Evaluation in accordance to criteria of the OECD Test Guideline: The test substance was not readily but inherently biodegradable under the conditions of this test.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
