Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation in water:
A study was performed to assess the ready biodegradability of the test material in an aerobic aqueous medium. The test followed that described method in the OECD TG 301B, "Ready Biodegradability; CO2 Evolution Test" referenced as Method C.4-C of Commission Directive 92/69/EEC.
The test material, at a concentration of 10 mg Carbon/L, was exposed to activated sewage sludge micro-organisms with culture medium in sealed culture vessels in the dark at approximately 21 °C for 28 days. The degradation of the test material was assessed by the determination of carbon dioxide produced. Control solutions with inoculum and the standard material, sodium benzoate, together with a toxicity control were used for validation purposes. The test material attained 78 % degradation after 28 days and satisfied the 10-Day window validation criterion. The test material can, therefore, be considered as readily biodegradable under the test conditions.
Additional information
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.
