Soaps and Detergents , contain particles we call miciles , these miciles have two ends -
one is hydrophobic(afraid of water) and another is hydrophillic(water loving), so when we apply soap on a dirty cloth , and put water on it the hydrophobic end sticks to dirt , whereas the hydrophillic end sticks ,to water, creating a sphere like body , with dirt in between and water at the outside , when we rub it , and dry , the water , the water takes the dirt with it , and the clth is cleaned.

The colloidal sized particle formed in water by association of simple molecules each having a hydrophilic end and hydrophobic end is called micelle
soap is sodium stearate in water soap gives the ions stearate anion and sodium ion
In stearate anion COO- group as affinity for water is called hydrophilic group
C17 H35 affinity for water is called hydrophobic end.(tails of the anion)
The tail part dissolves the grease and forms micelle, removed by washing with water.
For this a critical concentration of soap solution is required.
