The solution characteristics of the system linear alkylbenzene sulfonate (LAS)/Ca ++ /builder were studied using a dynamic surface tension technique. The results showed that the rate of CA ++ /LAS interaction is slower than the CA ++ binding rate of zeolite A. Consequently, zeolite A is effective in preventing precipitation of LAS by calcium ions. The data obtained from the study of Ca ++ binding detergent builders on solubilization of Ca(LAS) 2 showed that zeolite A was effective but the rate of solubilization was much slower than that for STPP. Incorporation of a small amount of phosphate with zeolite A in a detergent significantly increases the rate of solubilizing of Ca(LAS) 2 .
