Cleansing action of Soaps and detergents. Most of the dirt is oily in nature and oil does not dissolve in water. The molecule of soapconstitutes sodium or potassium salts of long chain carboxylic acids. ... Therefore, it forms an emulsion in water and helps in dissolving the dirt when we wash our clothes.

A soap is made of sodium/potassium salts of long chain carboxylic acids.
For example:
C17H35COONa
A soap is made of two parts, one is the hydrophilic part and the other is hydrophobic. The hydrophilic part is soluble in Water while the hydrophobic part is soluble in oil(most of the dirt is oily).
In the figure, the zig-zag lines represent the bond line formula of the Hydrophobic part and the circular part represents the hydrophilic part and the middle substance is the dirt. As you can observe the molecules form a cluster, the hydrophilic ends are on the surface of water while the hydrophobic ends accumulate the dirt. This formation is a micelle. These micelles stay in water as collioid(emulsion) and do not precipitate because of repulsion of hydrophilic ends. This formation can easily be washed away and the dirt is removed.
Detergents are the ammonium/sulphonate salts of long chain carboxylic acids. Detergents have a stronger cleansing property than soaps.
