Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
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.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
