Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 submission substance is readily biodegradable, i.e. 76.5% within 28 days (OECD 301F, 2017).
Additional information
A reliable key study is available on the ready biodegradability of the submission substance according to OECD 301F and in compliance with GLP (RL1). The test item was investigated for its ready biodegradability in a manometric respirometry test over a period of 28 days. The biodegradation was followed by the oxygen uptake of the microorganisms during exposure. Degradation rate of test item was calculated from the oxygen consumption by the aerobic activated sludge microorganisms after 28 days of incubation. The mean biodegradation at test end after 28 days was 76.5% (based on ThOD_NH4). Therefore, the test item is considered to be readily biodegradable. The 10-day window requirement does not apply due to the substance characteristics (mixture of similar constituents for which a sequential biodegradation may be assumed). The study was classified acceptable and satisfied the guideline requirements for ready biodegradability studies.
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.
