Description of key information
Under the conditions of the study, the test material was determined to have d(0.1), d(0.5) and d(0.9) values of 24, 61 and 120 µm, respectively.
Additional information
The particle size distribution of the test material was determined in accordance with the standardised guideline CIPAC MT 187 under GLP conditions using particle size apparatus based on laser diffraction. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Under the conditions of the study, the test material was determined to have d(0.1), d(0.5) and d(0.9) values of 24, 61 and 120 µm, respectively.
