Examples of emulsions include vinaigrettes, homogenized milk, liquid biomolecular condensates, and some cutting fluids for metal working. Two liquids can form different types of emulsions. As an example, oil and water can form, first, an oil-in-water emulsion, in which the oil is the dispersed phase, and water is the continuous phase.

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.
Therefore, since micro- means 10 −6 and emulsion implies that droplets of the dispersed phase have diameters close to 10 −3 m, the micro-emulsion denotes a system with the size range of the dispersed phase in the 10 −6 × 10 −3 m = 10 −9 m range. Note 3: The term “micro-emulsion” has come to take on special meaning. Entities of ...
A container with cream. Topical cream formulation is an emulsion semisolid dosage form that is used for skin external application. Most of the topical cream formulations contain more than 20 per cent of water and volatiles and/or less than 50 per cent of hydrocarbons, waxes, or polyethylene glycols as the vehicle for external skin application.

Examples include amongst others blood, pigmented ink, cell fluids, paint, antacids and mud. Artificial sols can be prepared by two main methods: dispersion and condensation. In the dispersion method, solid particles are reduced to colloidal dimensions through techniques such as ball milling and Bredig's arc method .
A Ramsden emulsion, sometimes named Pickering emulsion, is an emulsion that is stabilized by solid particles (for example colloidal silica) which adsorb onto the interface between the water and oil phases. Typically, the emulsions are either water-in-oil or oil-in-water emulsions, but other more complex systems such as water-in-water, oil-in ...
Commonly invert emulsions look much like a paste or thick cream and typical examples are mayonnaise, margarine (especially "low-fat" grades of margarine), pharmaceutical ointments, and cosmetic "creams". Emulsion inversion differs from emulsion breaking in that a breaking emulsion tends to separate the two phases into un-emulsified continuous ...
