It is a substance used to enhance the cleansing action of water. A detergent is an emulsifier, which penetrates and breaks up the oil film that binds dirt particles and a wetting agent, which helps them to float off. Emulsifier molecules have an oil-like nonpolar portion which is drawn into the oil and a polar group that is water-soluble; by bridging the oilwater interface, they break the oil into dispersible droplets (emulsion). As a surfactant, a detergent decreases the surface tension of water and helps it penetrate soil.
