Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test substance is found to be not hydrolytically stable at pH 7 and 9 but hydrolytically stable at pH 4. Decolorization at 60 and 81 % of the test item was observed in two studies. Such observations are also supported by a publication of Esteves F and Sousa E demonstrating an Advanced Electrochemical Oxidation Process (AEOP) concerning the electrochemical degradation of the vinylsulphone form of Reactive Black 5, in the presence of hydrogen peroxide and copper ions. The reaction between H2O2 and electrochemically generated Cu+ ions leads to the production of hydroxyl radicals, causing dye oxidation and degradation.
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.
