Description of key information
The test item is a dark brown, solid powder at 20 °C and 1013 hPa and the mean particle size (D50) of the test item is 48.6 μm.
The evaluation of thermal properties was based on a DSC analysis (0-520 °C): the substance does not melt up to 520 °C and no endothermal or exothermal events were observed.
The relative density of the test item is 1.5526 ± 0.0006 at 20 ± 0.2°C.
The substance is very soluble in water at room temperature (9.39 – 68.18 g/L at 20.0 ± 0.5 °C and pH 5.90-6.15) and its partition coefficient (n-octanol/water) stated as Log Pow is -1.078 ± 0.156 at 22.2 ± 0.2 °C and pH 5.90-6.05. For both determination the shake-flask method was used, combined with a validated photometric method.
No reactions with water or emission of flammable gases have ever been noted. Furthermore, for soluble dyes a reaction with water is not a desirable property from the use point of view. Therefore, the substance is not expected as a substance that in contact with water may react emitting flammable gases.
The vapour pressure of the test substance is expected to be negligible as the melting point is above 300 °C.
The surface activity is not expected for the substance as it is not a desired property of the material.
The flash point of the test item is not a relevant property as it is a solid which does not melt up to 520 °C.
The substance is not flammable but a relative self ignition temperature of 272.2 °C was found.
Screening procedure failed to evidence any reason for concern related to both explosive and self-reactive properties of the substance, as no exothermic or endothermic events occur between 0 °C and 520 °C.
The substance is considered not to be potentially oxidising, based on a review of the properties of the substance.
