Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

The biodegradability of test item was investigated following the testing procedures outlined into the OECD guideline 302 B. The test item resulted to be mainly eliminated during the first 3 hours, when 100 % of the initial DOC was removed. However, no information about the biodegradation of the test item can be deduced by the study outcomes.

The substance is a organometallic complex; it is not expected to be ready biodegradable, based on its chemical structure and its specific function. Commonly, dyes undergo a primary transformation, i.e. discolouration due to the interrupting the conjugation. Nevertheless, the degradation process involves more steps and take more time.
