There are certain substances which behave as normal, strong electrolytes at low concentration but at higher concentration they behave as colloidal solutions due to the formation of aggregated particles. Such colloids are called associated colloids and the aggregated particles are called micelles. Soaps and detergents are the example of associated colloids. the formation of micelles takes place above certain concentration called critical micellization concentration (CMC) and a characteristic temperature. What type of molecules form micelles?
