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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test)
- Version / remarks:
- 1992
- Deviations:
- no
- GLP compliance:
- yes
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic (adaptation not specified)
- Reference substance:
- benzoic acid, sodium salt
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 99.2
- Sampling time:
- 28 d
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- The maximum average degradation percentage of the test substance is 99.2% (at plateau, after 28 days). Furthermore, 60% degradation is obtained within the 10-day window even if the samples is an UVCB. Therefore, the substance can be considered as readily biodegradable.

Description of key information
The maximum average degradation percentage of the test substance is 99.2% (at plateau, after 28 days). Furthermore, 60% degradation is obtained within the 10-day window even if the samples is an UVCB. Therefore, the substance can be considered as readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- freshwater
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.
