Description of key information
FAT 20043 is a red brown coloured, odourless solid powder. The test substance did not melt or boil until 350 °C and thermic decomposition started at about 350 °C. The average density of FAT 20043 was found to be 1.1408 g/cm³ at 20 °C temperature, with a median particle size of 28.117 μm. The vapour pressure of FAT 20043 is not determined. In accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.5, this study does not need to be conducted if the melting point is >300 °C. The partition coefficient n-octanol/water at 20 °C was determined to: POW = 0.00451; Log POW = -2.35. The water solubility was determined to be 41.2 g/l (without correction for the purity) at a temperature of 20 °C. The surface tension was determined to be 64.363 mN/m at room temperature ca. 20 °C. Because the test substance is a solid the flash point was not determined. In accordance with Section 2 of REACH Annex XI, information requirement section 7.9, this study does not need to be conducted based on the physical state of the substance. According to ECHA guidance, flash point is only relevant to substances that are liquid at room temperature. FAT 20043 showed no auto-ignition until 550 °C and the substance is considered not to be highly flammable and does not ignite spontaneously when in contact with water or humid air. The analysis of the chemical structure of the test substance reveals no alerts for explosive properties. The calculated chemical oxygen balance is below the trigger value of -200 and the determination of the exothermic decomposition energy demonstrated no energy release above the critical value of 500 J/g. Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required. Oxidising properties of FAT 20043 was not determined. In accordance with Column 2 of REACH Annex VII, this study does not need to be conducted as this substance is incapable of reacting exothermically with combustible materials on the basis of its chemical structure.
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.
