the stubborn bonding (cohesive force) of dirt or grime is hard for water to break - though water posses the highest dielectric constant (80), amongst all liquids/gases.
The detergents when dissolved in water increase the dielectric constant so that all possible force of between grime is cancelled. In this way ionic contents are left either loose in the solution and/or are forced to form pairing with detergent constituents as per relative chemical affinities.
These dissociation or superposed associations are washed away with excess water and/or dilution (supports further dissociation)

I guess you would like to know how any soap cleans. The main problem with just trying to clean with water, is that water and oils do not mix.
The quick and easy answer is that soap acts as a bridge between the two.
Water is polar, and oil is non-polar; this is the reason that they avoid each other. Soap is a rather long molecule with one polar end and one non-polar end. In this way, it is kind of like an adapter, and allows the water to "grab" the oil molecule.

It depends on the composition of the detergent. You might want to start looking on Wikipedia because they have a pretty good article that I'd hate to basically repost.

The -OH ion when reacted with water makes it possilbe to break the weak bonds..
Example: when u put a drop of deterent on a floor with water u will understand..
