Description of key information
Additional information
Acid Brown 349 is a brown organic powder.
The DSC analysis showed release of water between 25-150 °C. followed by substance decomposition between 269 - 382°C. The decomposition onset is 299.8°C with an enthalpy energy equal to 163.9 J/g
Therefore both melting and boiling points were not recorded but estimated with Epiwin.
The particle size distribution of theAcid Brown 349 was analyzed using the Mastersizer 2000 tool and the d(0.5) resulted 98.86 µm (REACH&Colours Kft, 2013).
Acid Brown 349 is a soluble substance in water (12.2 g/l at 20 °C) and logPow was calculated as -1.7042, showing a greater affinity with the water phase, than the octanol phase (REACH&Colours Kft, 2013).
The relative density of the substance, analyzed by means of pycnometer method, is 1.679 at 20 °C(REACH&Colours Kft, 2013).
Acid Brown 349 is not flammable and it is not expected to be auto-flammable; the substance does not meet the criteria to be considered as explosive and it is deemed to be potentially not oxidising based on the chemical structure, the oxygen balance values and the known experience in the handling and use of substances.
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.
