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.
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.
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.
