Description of key information

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.
