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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

not ready biodegradable.
Key value for chemical safety assessment
Additional information
No data on target substance was available, thus a read across approach was followed. In particular, available data on Similar Substance 01, i.e. one of the major components of target UVCB substance, was used. Such component shows slight differences with respect to other minor components of the UVCB substance. Further details are available in section 13.
Studies on BOD5/COD and biological elimination, as TOC removal, were available and gave evidence of not ready biodegradability of the substance.
Such data is consistent with the technical function of the substance, i.e. dye, for which ready biodegradability is not a desirable property.
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.
