Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
For Acid Red 211 only few data on biodegradation in water are available to cover this endpoint. Among these two studies were selected as key study to cover this endpoint. FAT 20028/B was investigated to determine the biological oxygen demand (BOD5) and the chemical oxygen demand (COD). BOD5of FAT 20028/B was found to be 80 mg/g O2and COD was found to be 1071.24 mg/g O2. The corresponding BOD5/COD quotient can be calculated to 0.077, which demonstrates the substance to be not biodegradable. In another supporting study with FAT 20028/A, the inherent elimination after 21 days is 71 %. Additionally, few supporting studies available also consider the substance to be not biodegradable. Therefore, based on the biodegradation in water -screening tests, Acid Red 211 was considered as non-biodegradable.
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.
