Description of key information
Additional information
Acid Violet 054 is a violet organic powder.
The DSC analysis showed release of water between 25-120 °C followed by substance decomposition between 263- 415°C. The decomposition onset is 291.0°C with an enthalpy energy equal to 141.5 J/g.
The particle size distribution of Acid Violet 054 was analyzed using the Mastersizer 2000 tool and the D50 resulted 11.427 µm (REACH&Colours Kft, 2015).
Acid Violet 054 is a soluble substance in water (2.26 g/l at 20 °C) and logPow was calculated as -0.994, showing a greater affinity with the water phase, than the octanol phase (REACH&Colours Kft, 2015).
The relative density of the substance, analyzed by means of pycnometer method, is 1.527 at 20 °C (REACH&Colours Kft, 2015).
Acid Violet 054 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.
