Description of key information
THe d(0,5) of the test substance is : 10.6 µm, while d(0,9) is 32,2 µm and D(0.1) =4,7 µm
Additional information
The particle size of the test item was determined by Laser diffraction particle method. Water was used a dispersant in order to obtain test substance solution at 0.0139% (vol).
Before solulisation in water, the test substance is a white to grau granular solid with some powder formation during handling and storage.
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.
