Data source
Reference
- Reference Type:
- study report
- Title:
- Unnamed
- Year:
- 2 010

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
