The use of granular solid masterbatches reduces problems with dust typically inherent to the use of finer-grained solid additives. Solid masterbatches have longer shelf lives than solutions in solvents, which evaporate over time. The masterbatch usually contains 40–65% of the additive, but the range can be as wide as 15–80% in extreme cases ...
High-shear mixers are used in industry to produce standard mixtures of ingredients that do not naturally mix.

The molecules in a drop of food coloring added to water will eventually disperse throughout the entire medium, where the effects of molecular diffusion are more evident. However, stirring the mixture with a spoon will create turbulent flows in the water that accelerate the process of dispersion through convection-dominated dispersion.
