Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Basic Yellow 28 Acetate is only stable in presence of significant concentrations of free acetic acid; it can not be isolated as such.
The test substance is an aqueous solution in 40 % acetic acid. Therefore the acetic acid solution is relevant for the density and not the Basic Yellow 28 Acetate.
The density of acetic acid is 1.0446 at 25 ˚C
The density of Basic Yellow 28 Acetate is between 1.077 - 1.143
Key value for chemical safety assessment
- Relative density at 20C:
- 1.1
Additional information
The relative density of the methyl sulfate salt at ambient temperature (compared to water at 4 °C) is 1.34.
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.
