Materials and methods

Principles of method if other than guideline:
The particle size distribution of a sample of the test substance was performed using laser diffraction. A Malvern Master Sizer S was used. The sample was dispersed in deionized water and the solution was stirred mechanically and ultrasonically to guarantee homogenous dispersion of the particles.
GLP compliance:
not specified
Type of distribution:
volumetric distribution
