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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 292-602-7 | CAS number: 90640-80-5 A complex combination of polycyclic aromatic hydrocarbons obtained from coal tar having an approximate distillation range of 300°C to 400°C (572°F to 752°F). Composed primarily of phenanthrene, anthracene and carbazole

Description of key information
For anthracene oil itself, no data on biodegradation in water (screening tests) is available. The substance is poorly water soluble consisting of a wide range of polycyclic aromatic substances. The known characteristics and the complexity of the substance preclude performance of standard biodegradation screening tests.
As a substitute, biodegradation characteristics of individual PAH comprising anthracene oil can be used. For some of them (two- and three-ring PAH), there is evidence that they are at least inherently biodegradable. This information results mostly from non-standard biodegradation studies, as results of some of the standard tests are not consistent.
Taking into account that also recalcitrant PAH are present in anthracene oil, the substance as such has to be assessed to resist ready biodegradation.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
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.
