By definition, vinaigrette is an emulsion of an acid within a fat. To create the emulsion, mustard is a great ingredient to use. It's key to keeping the vinaigrette from separating.
Making vinaigrette – pouring oil into vinegar and mustard prior to whipping into emulsion. In general, vinaigrette consists of 3 parts of oil to 1 part of vinegar whisked into an emulsion. Salt and pepper are often added. Herbs and shallots, too, are often added, especially when it is used for cooked vegetables or grains.

Homogenized milk – an emulsion of milk fat in water, with milk proteins as the emulsifier; Vinaigrette – an emulsion of vegetable oil in vinegar, if this is prepared using only oil and vinegar (i.e., without an emulsifier), an unstable emulsion results; Water-in-oil emulsions are less common in food, but still exist:
In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
Creaming, in the laboratory sense, is the migration of the dispersed phase of an emulsion under the influence of buoyancy.The particles float upwards or sink depending on how large they are and density compared to the continuous phase as well as how viscous or how thixotropic the continuous phase might be.
Emulsifying wax is created when a wax material (either a vegetable wax of some kind or a petroleum-based wax) is treated with a detergent (typically sodium dodecyl sulfate or polysorbates) to cause it to make oil and water bind together into a smooth emulsion. It is a white waxy solid with a low fatty alcohol odor.
Mini-emulsion: emulsion in which the particles of the dispersed phase have diameters in the range from approximately 50 nm to 1 μm. Note 1 : Mini-emulsions are usually stabilized against diffusion degradation (Ostwald ripening (ref. [ 6 ] )) by a compound insoluble in the continuous phase .
