A micelle may be defines as the cluster or aggregated particles formed by associated collides in solutions. The formation of micelle takes place above certain concentration called Critical Micellization Concentration (CMS) and above a particular temperature called Kraft Temperature (Tk). Every micelle system has a specific value of CMC.Micelles are used as detergents and drug carriers and find applications in froth flotation and petroleum recovery. In the action of a detergent, the dust particle to be removed is carried away in the hydrocarbon interior (hydrophobic) of a micelle.
