Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

One study (REACH&Colours, 2012) was performed on the similar substance 1 following OECD 301D for assessing ready biodegradability. The substance under test conditions after 28 days showed a degradation of 0.6%. One study (Clariant, 2007) was instead performed on the similar substance 2, following OECD 302B for assessing inherent biodegradability: the biodegradation of the tested item reached 13 % after 28 days of incubation.

Direct Black 80:1 can be considered not biodegradable for Read across with similar substance 1 and 2, and also according to the estimation by prediction tool.
