![]() ![]() Such emulsions are known as microemulsions. Rather, a transparent appearance was achieved by making the size of the dispersed droplets small enough (i.e., less than about 0.08 microns) so as to be unresolvable by visible light. However, these emulsions did not achieve their transparency by matching refractive indexes. Transparent emulsions first became commercially available in the early 1960s. Emulsions must therefore include emulsifiers which help create and maintain the uniform fine dispersion of the inner phase in the outer phase, and retard or prevent coalescence of the droplets and eventual separation of the emulsion into its constituent phases. Emulsions are inherently unstable and tend to separate into their constituent phases. Conversely, in a water-in-oil emulsion, the water phase is finely dispersed in the oil phase and is referred to as the inner, discontinuous, phase, while the oil phase is the outer, continuous phase. It is therefore referred to as the inner or discontinuous phase, while the water phase is referred to as the outer or continuous phase. In this type of emulsion, the oil phase is composed of droplets that are finely dispersed in the water phase. In an oil-in-water emulsion, for example, the oil phase is comprised of ingredients which are substantially insoluble in water.
