Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Reactive Blue FC 75311 displays a low ready biodegradability in that it achieved 0% biodegradation in a 28-day study closed bottle test and was not inherently biodegradable, achieving 0% biodegradation in a modified Zahn-Wellens test. This indicates that the substance is unlikely to achieve a half life of less than 40 or 60 days within fresh water attributed to ready biodegradation alone.
