For w o microemulsion, one start with o w emulsion stabilized with an ionic or nonionic surfactant. this emulsion is titrated with a co surfactant and the emulsion passes through a gel phase, after which further addition of co surfactant result in the production of w o microemulsion.

Lec 1 Emulsion Pdf Emulsion Surfactant Emulsions are thermodynamically unstable, as fusion or coalescence of droplets, the dispersed and continuous phases can revert back to distinct phases, oil and water. a mechanical force is necessary to disperse one phase into another and produce an emulsion. Definition: an emulsion is a heterogeneous mixture of two immiscible liquids where one liquid (the dispersed phase) is dispersed in the form of small droplets throughout the other liquid (the continuous phase). Microemulsions are liquid dispersion of water and oil that are made homogeneous, transparent and stable by the addition of relatively large amount of a surfactant and a co surfactant. they appear to represent a state intermediate between thermodynamically unstable emulsions and solubolised systems. Emulsions are liquid liquid colloidal systems where one liquid is dispersed in another immiscible liquid in the form of fine droplets. common examples are milk and vanishing cream.

An emulsion is a thermodynamically unstable mixture of two immiscible liquids, requiring an emulsifying agent for stabilization. various types of emulsions exist, including macro emulsions, nano emulsions, and micro emulsions, each with distinct size ranges and stability characteristics. The purpose of this review article is to provide information about types of emulsions, stability mechanisms and rheological studies as well as factor affecting the stability of emulsions. keywords: emulsion, emulsion type, stability mechanism, viscosity, droplet size. 4.1 emulsion and foam structure as droplet microemulsions, emulsions are dispersions of spherical oil or water drops, covered with a layer of surface active agent.
