A surfactant is the most important part of any cleaning agent. The word surfactant is short for "Surface Active Agent." In general, they are chemicals that, when dissolved in water or another solvent, orient themselves at the interface (boundary) between the liquid and a solid (the dirt we are removing), and modify the properties of the interface.
