Additional information

The test substance is a dark-red brownish powder. The substance did not melt or boil under the conditions of the test. Because the substance is solid at room temperature, the flash point could be waived. The density at 19.5°C is 1766 kg/m3 with a mass median diameter of 41.8 µm and the particle size distribution in a range from approximately 0.3 µm to 200 µm. The vapour pressure of the two main components of the test substance was estimated to be: 9.8E-25 and 1.7E-24 based on the calculated boiling points by using the Modified Watson Correlation. The calculated partition coefficient between n-octanol and aqueous phase is: log Pow: <-5.5. The water solubility of the test substance is ≥419 g/L at 20°C and the surface tension of aqueous solution at 21°C was determined to be 75.3 mN/m at a concentration of 0.1%. The auto flammability temperature was 342°C and the test substance is considered not to be highly flammable. The test substance is not explosive, has no oxidizing properties, but dissociates in water. Classification of the test substance is not needed according to the Directive 67/584/EEC and according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
