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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 water:
- readily biodegradable but failing 10-day window
Additional information
A non-GLP guideline study according to OECD 301E is available for the assessment of the biodegradability of the test substance. In this study, the biodegradation degree was measured to be approx. 87 % (based on DOC removal) after a test duration of 28 days ( BASF AG 1/91/0040/20/1, 1991). Although there was no DOC-measurement implemented after 3 hours, an adsorption of the test item to the inoculum can be excluded since there was no elimination detectable after one day of exposure.
Since the substance is multiconstituent, the 10-days window concept does not apply. The very high degree of biodegradation after 28 days in the screening test (approx. 90 %) demonstrates however that the substance is rapidly and extesively removed from the environment via microblal degradation
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.
