How does detergent break surface tension

WebBecause the surface of the water is aligned with air, the water molecules are attracted to one another from side to side. This creates surface tension. But when you add the … WebAs a detergent, Dawn contains surfactants that lower the surface tension of water. This allows the soap to spread and easily attach to grease in order to break it up, as well as wash it away. The professional liquid dish detergent by Dawn creates long-lasting suds that also help to attack food soils and oils for quicker results.
