Description of key information
The test item is a brown, solid powder at 20 °C and 1013 hPa and the mean particle size (D50) of the test item is 25 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 1.7658 ± 0.0009 at 20.0 ± 0.2 °C.
The substance is very soluble in water at room temperature (266.9 ± 2.1 g/L at 20.0 ± 0.5 °C and pH 6.24 – 6.26) and its partition coefficient (n-octanol/water) stated as logPow < -2 at 21.0 °C and pH 7.27 - 7.54. 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. In addition, 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 224.7 °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.
Additional information
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.
