* Surface tension theory – according to this theory, emulsification takes place by reduction of interfacial tension between two phases
* Repulsion theory – According to this theory, the emulsifier creates a film over one phase that forms globules, which repel each other. This repulsive force causes them to remain suspended in the dispersion medium
* Viscosity modification – emulgents like [[Gum arabic|acacia]] and [[tragacanth]], which are hydrocolloids, as well as PEG ([[polyethylene glycol]]), glycerine, and other polymers like CMC ([[carboxymethyl cellulose]]), all increase the viscosity of the medium, which helps create and maintain the suspension of globules of dispersed phase
