An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used … Visa mer The word "emulsion" comes from the Latin emulgere "to milk out", from ex "out" + mulgere "to milk", as milk is an emulsion of fat and water, along with other components, including colloidal casein micelles (a type of … Visa mer A number of different chemical and physical processes and mechanisms can be involved in the process of emulsification: • Surface … Visa mer • Emulsion dispersion • Emulsified fuel • Homogenizer Visa mer Emulsions contain both a dispersed and a continuous phase, with the boundary between the phases called the "interface".
