Micelles formation is done by substances soaps and detergents when dissolved in water. The aggregate of colloidal particles which have both hydrophobic and hydrophilic parts are called micelles. These are formed above a particular temperature called Kraft's temperature (Tk) and above certain concentrations, called Critical Micellar Concentration (CMC).
When present in water, these substances arrange themselves in the spherical structure in such a manner that their hydrophobic parts are present towards the centre, while the hydrophilic parts are pointing towards the outside (as shown in the given figure). This is known as micelles formation.
These molecules are arranged radially with the hydrocarbon or non-polar part towards the centre and the periphery.
Some examples of Micells System:
Sodium Stearate + Water
Sodium dodecyl + Water
Cetyltrimethylammonium bromide + water
