Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The 5-day biological oxygen demand (BOD5) is 0 mg O2/mg test substance. The theoretical oxygen demand (TOD) is 0.384 mg O2/mg test substance. Additionally, two QSAR calculations are available showing that the teat substance is not readily biodegradable.

Moreover, the pigment is practically insoluble and therefore considered to be essentially not bioavailable. Due to the large molecular size, cellular uptake of the pigment is unlikely. Hence intracellular biodegradation, which is the main degradation route of bacteria, is probably low. Therefore, in overall conclusion, it is likely that the test substance is persistent in the environment.
