Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Stability

Hydrolysis

The read across substance Direct Red 83:1has been determined to undergo less than 10% hydrolysis in pH 4, 7 and 9 buffer solutions after 5 days at 50.0 ± 0.5 °C.  The Half-life (t1/2) is considered to be greater than 1 year, and therefore the  test substance was considered  hydrolytically stable.

 

Biodegradation

Biodegradation in water: screening test

The read across substance Kayarus Supra Rubine BLN attained only 6% degradation with 28 days, therefore the test substance is considered to be as not readily biodegradable.

 

Transport and distribution

Adsorption / desorption

A study on adsorption/desorption does not to e conducted because the substance has a low octanol water partition coefficient (log Kow = -2.14 at 20 °C) and the adsorption potential of this substance is related to this parameter.
