As a result of this repulsive force, they can remain suspended in the dispersion medium. Repulsion theory: According to this theory, the emulsifying agent develops a film over one phase, resulting in the formation of globules that resist one another.Surface tension theory: A reduction in interfacial tension between two phases, according to the surface tension hypothesis, is what causes emulsification to take place between two phases.Emulsification Processes and MechanismsĪn emulsification process can involve various chemical and physical processes and mechanisms, all of which are discussed in detail below.

Mayonnaise, milk, lotions, and other mixed products are called emulsions. However, even though the terms colloid and emulsion are often used together, the emulsion is only used when both phases are liquid. Emulsions are classified into oil in water and water in oil.Īn ideal example of oil in water emulsion is butter and chilled cream.Emulsions are a type of colloidal system, a more general term for two-phase matter methods.

The emulsion is a immiscible combination of two or more liquids. What is an Emulsion?Įmulsions refer to two separate liquids that mix into one. An emulsion is made by mixing two or more liquids and making them mix. It comes from the Latin word for “milk” (milk is one example of an emulsion of fat and water). An emulsion is a mixture made by putting two liquids together that do not usually mix.

One of the two or more liquids has a small amount of the other liquid. When two or more liquids do not mix, they make an emulsion.
