Emulsion
This article is about mixtures of liquids. For the light-sensitive mixture used in photography, see Photographic emulsion. Two immiscible liquids, not yet emulsified An emulsion of Phase II dispersed in Phase I The unstable emulsion progressively separates The surfactant (outline around particles) positions itself on the interfaces between Phase II and Phase I, stabilizing the emulsion IUPAC definition Fluid system in which liquid droplets are dispersed in a liquid. Note 1 : The definition is based on the definition in ref. [1] Note 2 : The droplets may be amorphous, liquid-crystalline, or any mixture thereof. Note 3 : The diameters of the droplets constituting the dispersed phase usually range from approximately 10 nm to 100 μm; i.e., the droplets may exceed the usual size limits for colloidal particles. Note 4 : An emulsion is termed an oil/water (o/w) emulsion if the dispersed phase is an organic material and the continuous phase is water or an aqueous solution and is termed water/...
