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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 soil
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in soil: simulation testing
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is readily biodegradable
- Endpoint:
- biodegradation in soil: simulation testing
- Type of information:
- other: published data
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Justification for type of information:
- The test substance (sodium dodecylbenzenesulfonate as a read across for Sodium cumenesulphonate)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 307 (Aerobic and Anaerobic Transformation in Soil)
- GLP compliance:
- not specified
- Test type:
- laboratory
- Radiolabelling:
- yes
- Oxygen conditions:
- aerobic/anaerobic
- Soil classification:
- other: Alfisol
- Details on soil characteristics:
- - Soil : Air-dried and sifted to a particle size of 0.125 mmparticle size distribution ; Clay(<2 μm) 17%, silt(2-63 μm) 75%, sand(0.63-2 mm) 8%, organic matter 2.45%- Soil pH : 7.3
- Initial conc.:
- 15 other: μg
- Based on:
- test mat.
- Details on experimental conditions:
- - Experience vessels; 1 litre wide-mouth bottles- Incubation mixture; 50g soil and 150ml water were equilibrated for 7 days at 35 deg C in oxygen or nitrogen. Then 15μg of 14C-labelled chemical was added in aqueous solution ot suspension.- Mechnical mixing; continuous shaking in a water bath (35 deg C)
- % Degr.:
- >= 40.6 - <= 51.9
- Parameter:
- CO2 evolution
- Sampling time:
- 42 d
- Transformation products:
- yes
- Conclusions:
- The test substance (sodium dodecylbenzenesulfonate as a read across for Sodium cumenesulphonate) was readily biodegradable. And the degradation (mineralization) values in anaerobic environment was faster than those in aerobic environment

Description of key information
The study does not need to be conducted because the substance is ready biodegradable.
The test substance (sodium dodecylbenzenesulfonate as a read across for Sodium cumenesulphonate) was readily biodegradable. And the degradation (mineralization) values in anaerobic environment was faster than those in aerobic environment.
Key value for chemical safety assessment
- Half-life in soil:
- 42 d
- at the temperature of:
- 20 °C
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.
