Polyphosphates gave renewed life to soap products at a time when surfactants were a threat though expensive , and these same polyphosphates spelled the decline of soap usage when the synergism between polyphosphates and synthetic detergent actives was recognized and exploited .

Physicochemical investigations of anionic surfactants , including the soaps , have shown that there is little polymerization or agglomeration of the chain anions below a certain region of concentration called the critical micelle concentration .

In the cleaning process , sorbed greasy soils become coated in this manner with an oriented film of surfactant .
