The physico chemical properties of a detergent (Sodiumdodecylsulfate, 20%, builder 20%, sodium silicate, 5%, carboxymethyl-cellulose, 1%, and sodium sulfate, 54%, ) were studied to decrease sodium tripolyphosphate (STPP) in the detergents. Builders were examined for binary systems consisting of STPP and Zeolite in the various ratios. <BR>In this study, we used synthetic Zeolite being prepared from sodium aluminate and sodium silicate by the water phase method. The rate of calcium ion exchange was measured by a ionic-electrode method, and was also examined with calcium ionic sequestration in the binary systems of STPP/Zeolite. <BR>The detergents were also examined for pH, surface tension, foam performance, and detergency. As a result, it was found that the binary components of STPP and Zeolite behaved more effectively as detergent builder in the formula.
