Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 and sediment: simulation tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: simulation testing on ultimate degradation in surface water
- 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 highly insoluble in water
- the study does not need to be conducted because the substance is readily biodegradable
- Justification for type of information:
- According to Regulation (EC) No. 1907/2006, Column 2 of Annex IX, simulation testing on ultimate degradation in surface water does not need to be conducted if the substance is readily biodegradable or is highly insoluble in water. The substance has been determined to be readily biodegradable (i.e., 80% degradation in 28 d and meeting the 10-d window) and is insoluble in water (i.e., 0.08994 mg/L at 25˚C); therefore, simulation testing on ultimate degradation in surface water is waived.

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.
