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:
