Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 registered substance was readily biodegradable in a study according to OECD test guideline 301B under GLP (meeting the 10-day window).
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The registered substance was investigated in a study according to OECD test guideline 301B (CO2 Evolution Test). The mean cumulative CO2 from the test substance, procedural control, toxicity control and blank control test vessels was 37.61, 47.36, 64.14 and 18.71 mg/L, respectively, at day 29.
The cumulative net percent CO2 production (blank control values substracted), or percent ultimate biodegradation, for the test substance, procedural control, and toxicity control was calculated to be 63.63, 78.14, and 68.44%, respectively.
The cumulative net CO2 evolved from the sodium benzoate procedural control was 66.12% of theoretical by day 11, thus exceeding the "pass" criterion of the test and confirming the presence of an active microbial population and system integrity.
Based on the CO2 results, the test substance is readily biodegradable according to the OECD test guideline 301B.
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.
