Emulsion is a mixture of two or more liquids in which one is present as droplets, of microscopic or ultramicroscopic size, distributed throughout the other. Emulsions are formed from the component liquids either spontaneously or, more often, by mechanical means, such as agitation, provided that the liquids that are mixed have no (or a very limited) mutual solubility.
There are two basic types of emulsions: oil-in-water (O/W)-cream
and water-in-oil (W/O). -butter

An emulsion is a mixture of two or more liquids that are normally immiscible (nonmixable or unblendable). It means that in an emulsion the dispersed phase and dispersion medium are both liquids.

There are two basic type of emulsions: oil in water and water in oil.

In every emulsion there is a continuous phase(dispersion medium) that suspends the droplets of the other element which is called the dispersed phase.

(i) Oil-in-water emulsions (O/W) : The emulsion in which oil is present as the dispersed phase and water as the dispersion medium (continuous phase) is called an oil-in-water emulsion. Milk is an example of the oil-in-water type of emulsion. In milk liquid fat globules are dispersed in water. Other examples are, vanishing cream etc.
ii) Water-in-oil emulsion (W/O) : The emulsion in which water forms the dispersed phase, and the oil acts as the dispersion medium is called a water-in-oil emulsion. These emulsion are also termed oil emulsions. Butter and cold cream are typical examples of this types of emulsions. Other examples are cod liver oil etc.

If both dispersed phase & dispersion medium are liquud (immiscible ), then that collidal system is called an emulision 
Types of emulision 
a) olive dispersed in water (O/W type)
Dispersed phase =oil 
Dispersion medium=water 
e.g,milk vanishing cream ,etc.
b)water dispersed in oil (W/O type )
Dispersed phase =water 
Dispersion medium =oil
e.g,butter ,cold cream,etc.

Emulsions are colloidal solutions with both dispersed phase and dispersion medium being liquid. Thus, finely divided droplets of one liquid are dispersed in another medium. Emulsions can be formed from any two imiscible liquids.
Two types of emulsions include oil in water emulsion and water in oil emulsion.
Oil in water emulsion :
                    The dispersed phase is oil. It is present in small amount. The dispersion medium is water. It is present in large amount. 

For example, milk is an emulsion of soluble fats in water.
Water in oil emulsion :          
  The dispersed phase is water. It is present in small amount. The dispersion medium is oil. It is present in large amount. 
For example, butter is an emulsion of water in oil.
