Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test item was considered to be not inherently biodegradable.
Additional information
A study was performed to assess the inherent biodegradability of the test item in an aerobic aqueous media according to OECD Guideline 302B, EU Method C.9 and US EPA Test Guideline OCSPP 835.3200. In this study, the test item was exposed to activated sewage sludge micro-organisms at a concentration of 100 mg carbon/L with mineral medium in the dark at temperatures of between 20 and 25 ºC for 28 days. The biodegradation of the test item was assessed by the determination of dissolved organic carbon removal. Control cultures with inoculum and the reference item, diethylene glycol and a toxicity control were used for validation purposes. The test item attained 0% biodegradation after 28 days. The test item cannot therefore be considered as inherently biodegradable under the experimental conditions employed in this study.
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.
