Description of key information
Additional information
No data on Acid Yellow 049 sodium salt was available.
Available data on Acid Yellow 049 lithium salt was considered as representative and suitable to be used in a read-across perspective. Details on the read across are reported in section 13.
Acid Yellow 049 sodium salt is a yellow powder.
Based on read across data, the relative density is ca. 1.5 at 20 °C and the mass median diameter is ca. 38 µm. It is very soluble in water and it has a slightly negative log Kow.
In a DSC analysis between 25 and 450 °C, no melting or boiling point is recorded. Decomposition is observed between 319 and 388 °C. Vapour pressure can be considered as negligible; surface tension is not a desirable property of the substance.
It is non flammable, non oxidising, non explosive and has no spontaneous ignition property.
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.
