A soap molecule is a sodium or potassium salt of long chain carboxylic acid. It consists of two parts, i.e., a long hydrocarbon tail and a negatively charged head. The hydrocarbon tail is hydrophobic, i.e., insoluble in water and repelled by water while the polar end is soluble in water and hydrophilic in nature. When soap is applied on a wet dirty surface, the polar end of the soap molecule dissolves in water while the non-polar end attaches it to dirt molecule, as dirt is non-polar in nature. This results in the formation of spherical clusters called as Micelles. In micelle the hydrophobic tails are in the interior of the cluster while the ionic ends are on the surface of the cluster. Due to ion-ion repulsion the micelle stay in the solution as a colloid and do not come together to form precipitate. Thus, an emulsion is formed which helps to dissolve dirt in water and it is finally washed with running water.

The principle of cleansing actionis based on the following principles:1.Dissolution of soap in water and formation of soap micelles.2. Its hydrophobic end attract towards dirt and grease while the hydrophillic ends remain separated in water by the action of ion repulsion.3. After rinsing of clothes these micelles get out of the clothes along with the water.
