Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
It is considered scientifically unjustified to perform a hydrolysis study for this substance.
Key value for chemical safety assessment
Additional information
Basic Yellow 28 Methylsulfate is produced in aqueous solution. The test substance is then spray-dried under mild conditions, due to its rather low melting point. Basic Yellow 28 Methylsulfate has a sufficiently high solubility in water. The substance is stable at high temperatures. Before the dyeing process starts the substance is dissolved in hot water / acidic acid at about 80 °C to form the dye acetate (dyeing takes place at 96 to 105 °C at pH 3 to 4.5). It is hence considered scientifically unjustified to do an additional study for abiotic degradation of this substance.
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.
