For example, in oil-water cutting fluid emulsion used for metalworking is formed by emulsifying oil in the water medium. Thus, we can say to emulsifying two immiscible liquids is called emulsification. In this process, one immiscible liquid is dispersed in another immiscible liquid. The process of formation of emulsions is called emulsification. The term emulsion comes from the Latin word ‘emulgere’ which means ‘to milk out’.Įxamples of Emulsions – Milk, mayonnaise, hand creams (lotions), Latex, cutting fluid, vinaigrettes, etc. For example, aerosol (Examples – Clouds, Fog, etc.) is also a colloidal solution in which the dispersion medium is gas and the dispersed phase is liquid. In colloidal solution, it is not necessary that both dispersed phase and dispersion medium will always be liquids. But it does not mean that all colloids are emulsions.
The term emulsion is specifically used for mixtures in which dispersed phase and dispersion medium both are liquids.
Generally, students get confused between the terms - emulsion, and colloid. In this article we will discuss various emulsions, properties of emulsions, what is emulsification and its mechanism, and much more related to emulsification.Ī mixture of two or more liquids that are normally immiscible is called Emulsion. These types of mixtures are known as emulsions. As we know oil and water are two immiscible liquids, but milk is an example of a mixture in which oil (fats) particles are suspended in water.
