Detergents work like soaps.

It contains the polar hydrophilic and non-polar hydrophobic ends.

"The polar ends bind with the water molecule which decreases the hydrogen bonding among the water molecules".

The hydrogen bonding in water molecules causes surface tension

The intermolecular forces that are found in soaps are Vander Waals attraction, hydrogen bonds along ion-dipole interactions
