Type A zeolite of various sizes from 1.4 μm to 0.15 μm in average were synthesized. in an anionic surfactant solution. The synthetic conditions such as mixing temperature of starting solutions, aging time and Na\2O/SiO_2 ratios in the reaction mixtures were explored for obtaining the crystals of desired sizes. Calcium-ion exchange capacities of the fine particle zeolites are as high as those of commercial products of several microns in average diameter. As to the relation of the mean particlediameter, the turbidity of detergent solutons containing the fine zeolites was expressed as : In I_0/I=0.4+0.18 ln D where D is a mean particle diameter in μm. Builder effects of the fine zeolites on the detergency were discussed on the basis of mean particle diameter.
