Description of key information
The test substance is a dark orange powder. It does not melt or boil under the conditions of the test up to 400 °C. The density of the test substance is 1400 kg/m³ at 20.1°C ± 0.1°C. The mass median diameter of the test substance was determined to be 7 µm. The particle size distribution was found to range from approximately 0.5 µm to 30 µm. The vapour pressure of the test substance was estimated at 25 °C, based on the boiling point calculated and using the Modified Watson Correlation, to be 7.23 x 10 -25 Pa. The calculated partition coefficient of the test substance between n-octanol and aqueous phase is: log Pow = <-5.9. The water solubility of the test substance is 275 g/L at 20 °C. The surface tension of the test substance at 20.3 °C in water was determined to be 67.9 mN/m. The auto flammability temperature of the test substance is 279 °C. The test substance is not "highly flammable". The test substance is not explosive nor have oxidizing property. The behaviour of the test substance in aqueous solutions is dominated by the strongly acidic -SO3H-groups. Therefore, the molecule is negatively charged and is present in anionic form over the whole environmentally relevant pH range.
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.
