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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data

Description of key information
The substance is degraded by > 70 % within 10 days and is considered to be “readilv biodegradable”.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of the substance was determined in the DOC DIE-AWAY Test in the course of 28 days.
The reference item Sodium benzoate achieved a degree of degradation of > 70 % in 14 days indicating that the inoculum used had a sufficient biological activity. The toxicity controls reached a degree of degradation of 85 % resp. 87 % in 28 days. No toxic/ inhibitorv effects of the test item concentrations used were observed.
The test substance reached a degree of degradation of 61 resp. 71 % (DOC decrease) in the course of 28 days.
Since the higher concentration of the substance is degraded by > 70 % within 10 days after the time at which the biodegradation has reached 10 %, the substance is considered to be "readily biodegradable“.
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.
