Understanding How Detergents Actually Work

Cleaning a soiled surface is a four-step process. In the first step, the surface to be cleaned is made wet with water. In the second step, soap or detergent is applied to the surface to be absorbed. Soaps and detergents are also called surface-active agents, or surfactants. Surface active molecules present in soaps and detergents dissolve in water.

Sodium dodecyl sulfate | C12H25NaO4S - PubChem

Sodium dodecyl sulfate is an organic sodium salt that is the sodium salt of dodecyl hydrogen sulfate. It has a role as a detergent and a protein denaturant. It contains a dodecyl sulfate. Dodecyl sulfate, [ sodium salt] appears as white to pale yellow paste or liquid with a mild odor. Sinks and mixes with water.

Science on the Shelves - Soapy Science

The detergent molecules also help to make the washing process more effective by reducing the surface tension of the water. Surface tension is the force which helps a blob of water on a surface hold its shape and not spread out. The surfactant molecules of the detergent break apart these forces and make water behave, well, wetter! Back to the top.
