Description of key information
The test substance is black-green powder at room-temperature. The melting point of test substance is above 572 K. The relative density of the test material was determined to be 1.74 at 23 °C. The median of mass distribution (width) was determined to be 410 μm. The partition coefficient (Log Pow) was determined to be -1.14 at 25 °C. The water solubility of the test substance was determined to be greater than 48 g/L. The fat solubility of test substance is lower than 0.1 mg/100 g fat at 37 °C. The surface tension of FAT 45155/B was 61.5 - 61.7 mN/m (10.0 g/L aqueous solution at 20 °C). The self-ignition temperature was determined to be 365 °C. The test substance is not considered highly flammable, not explosive nor having oxidizing properties. Thermal stability of FAT 45155/B in air is considered to be stable with or without air. The dissociation constant of the test material were determined to be pKa1 as 8.02 and pKa2 as 11.97.
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.
