Description of key information
Based on visual observation made upon receipt by Defitraces, a testing laboratory involved in the performance of phys-chem tests in view of REACH registration (Klimisch score 2, Demangel, 2017), the test item can be described as a white powder. Additionally, based on the safety data sheet of a manufacturer (Klimisch score 2, TIAG, 2015), the test item is a white odourless powder. Both data sources have been included in a weight of evidence approach for endpoint coverage.
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
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.
