The physico-chemial properties of the detergents (sodium linear alkylbenzenesulfonate 25%, builder 25%, sodium silicate 5%, sodium sulfate 44%, and carboxymethyl cellulose 1%, ) were studied in order to decrease the quantity of sodium tripoly-phosphate (STPP) in the detergents. Builders were examined for binary systems consisting of STPP and sodium citrate in the ratios of 1 : 0, 3 : 1, 1 : 1, 1 : 3, and 0 : 1 by weight. The detergents were also examined for pH, surface tension, foam performance, dispersion capacities, soil redeposition, and detergency. The detergents with binary components of STPP and sodium citrate behaved more effectively than a detergents with single component of sodium citrate.
