Description of key information
mean hydrodynamic diameter = 1.0 μm
Additional information
The particle size distribution of the substance was evaluated by means of Dynamic Light Scattering (DLS). The powder sample were suspended in water at a concentration of 1 wt %. The suspensions thus obtained were placed in an ice bath and sonicated for 6 minutes using a sonicator with probe applying an intensity of 5 in continuous mode. The samples were left at room temperature for 5 minutes and then 1 ml of each sample in suspension was placed in disposable plastic cuvettes and examined by DLS analyzer. The sample was analyzed immediately after sonication.
Mean hydrodynamic diameter = 1.0 μm, Standard deviation = 0.3
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.
