The way soap acts?
Liquid molecules experience mutual attraction forces, thus causing surface tension.
By getting into the surface layer of water, soap molecules noticeably weaken the surface tension forces.
Soap and laundry detergents reduce the surface tension of water, increasing its permeability. Therefore, soapy water soaks in and cleans fabrics and other materials, taking the dirt away with it.
