Emulsifier Definition and simple Explanation

An Emulsifier which is one of the important property can be explained in many ways. Emulsifiers are used when one part is water and another  part is oil based, and you want to mix both this parts and would like to form an emulsion. It is one kind of substance which stabilizes an emulsion by increasing its kinetic energy for example (surface acting agents - Surfactants).

Emulsifier is explained with simple explanation, so let us find it out more about this important property with example.
Suppose if you keep oil and water is a same plate or a glass, but after some time you will find that they would not mixed properly, you will find separate  phase , one phase with water and other phase with oil, only little part of both of them will mix at the middle, which is known as surface tension. One barrier or a fence will create between both of them , Now we want to overcome with this problem , so what is the solution? The answer is to use emulsifiers which will allow to mix both this immiscible phase.
They make it possible for oil as well as water to easily and finely dispersed in each other creating homogenous, stable and smooth emusion.
