Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Experimental results from two studies on bioaccumulation conclusively show that the substances comprised by the Diarylide Yelow Pigments are not bioaccumulative. In both studies concentration in fish were lower than the limit of detection. Thus, the determined bioaccumulation factors are upper limits representing the detection limits of the analytical methods. This is expected as the log Powof the substances is low and they are highly insoluble in water as well as organic solvents / fat.
