Description of key information
The ready biodegradation of the test item was investigated in a study conducted according to OECD Guideline 301 F and EU Method C.4 -D over a period of 28 days and using activated sludge as inoculum collected from a sewage treatment which is mainly fed with municipal wastewater. The test item proved to be readily biodegradable and fulfilling the 10-d-window criterion (>85% biodegradation after 28 d of incubation). The functional control reached the pass level > 60% after 14 d. In the toxicity control containing both test and reference item 61 and 65% biodegradation based on oxygen consumption occurred within 14 d thus indicating that the test item was not inhibitory to the activated sludge microorganisms at the concentration tested.
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.
