Relationship between SC Stability withParticle Size and Size Distribution

The relationship between milling time of SC formulation processing with particle size and size distribution in suspension was described by studying the relationship of SC stability with particle size and size distribution. The result showed suspension physical stability could be improved by adjustment of milling time and decrease of particle size and size distribution, while suitable adjuvant and processing conditions were selected. Increase the viscosity of the suspension due to longer milling time and smaller particle size, would be more helpful to physical stability of the suspension.
