A study was made of the effect of zeolite in detergent on the removal of soils correlating the characteristics of soil components. The detergency of natural soil was increased with increasing zeolite concentration but the effect on detergency was inferior to STPP. In case of carbon black based artificial soils. The detergency of soil containning non-polar oily soil was not improved by zeolite but the detergancy was increased with increasing zeolite concentration when polar oily soils were added to the soil. In case of iron black based artificial soils. Though the detergency was better than that of carbon black based soils, the detergency was not improved by zeolite regardless of oily soil components. The effect of zeolite on removal of oily soil was studied with tripalmitin and palmitic acid as model soils. The effect of zeolite and STPP on the removal of tripalmitin, the detergency was increased with in creasing STPP concentration but not zeolite.
