Abstract: The present invention discloses zeolite 4A with molar oxide composition of 1.017Na 2 O • Al 2 O 3 • 1.973SiO 2 • 4.725H 2 O that has external specific surface area of 2.37-4.43 m 2 /g according to Brunauer-Emmett-Teller (BET) isotherm; and - external surface roughness as indicated by the ratio of RSSA/GSSA within the range of 2.58-2.81. Particles size of zeolite 4A are ranging from 0.4 μm to 5 μm, wherein 50% of all particles size are smaller than 1.45 μm, and 90% of all particles size are smaller than 2.35 μm. Invention can be used as detergent builder, ion-exchange agent, sorbent, and carrier of organic molecules.
