Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: Laser scattering (Mie scattering theory)
- Deviations:
- not specified
- Principles of method if other than guideline:
- In general, the scattering of the incident light gives distinct pattern which are measured by a detector. The particle size distribution of test substance was determined by a particle size analyzer GSL-101BI. Details refer to report attached.
