surface-active agent

A surface-active substance that when added to water lowers surface tension and increases the “wetting” capabilities of the water. Reduced surface tension allows water to spread and to penetrate fabric or other substances to be washed or cleaned. There are three categories of surfactants: detergents, wetting agents, and emulsifiers. “Surfactant” is a contraction for surface-active agent.
