What are the 3 types of emulsions?
There are three kinds of emulsions: temporary, semi-permanent, and permanent. An example of a temporary emulsion is a simple vinaigrette while mayonnaise is a permanent emulsion.

What are the 2 types of emulsion?
There are two basic types of emulsions: oil-in-water (O/W) and water-in-oil (W/O). These emulsions are exactly what they sound like, as pictured below. In every emulsion there is a continuous phase that suspends the droplets of the other element which is called the dispersed phase.
What is emulsion example?
An emulsion is a type of colloid formed by combining two liquids that normally don't mix. In an emulsion, one liquid contains a dispersion of the other liquid.

What is emulsion and types?
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 immiscible liquids. Two types of emulsions include oil in water emulsion and water in oil emulsion.
