[Terminology] Dispersion effect
Definition of dispersion: A substance (dispersed phase) is dispersed in another substance (dispersed medium), and may form a dispersion system.
Typically, stability of dispersion system is controlled kinetic factors. Dispersion system may occur aggregation and flocculation; thereby stability of dispersion system is destroyed.
Surfactants can effectively control stability of dispersion system. When dispersion system is stable, this indicates that surfactants play dispersion effect.
Surfactants can also destroy stability of dispersion system. For example: surfactants also have flocculation, coagulation, aggregation effects.
