Description of key information
Additional information
The tests performed by BASF indicate that the substance is at least biodegradable without being readily biodegradable according to OECD criteria. Due to the formation of an unknown metabolite which suppresses further biodegradation, biodegradation stops after 4 days of test duration when non-adapted inoculum is used. If adapted inoculum is used, this metabolite is also degraded and the test results in degradation rates between 90 -100% after 28 days, slightly failing the 10-day window. Furthermore, phthalonitrile can be easily eliminated from water.
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.
