Process for preparing a stable, freeflowing dishwashing composition

Claim 1

A PROCESS FOR PREPARING A STABLE, FREE-FLOWING DISHWASHING COMPOSITION FOR MACHINE DISHWASHERS CHARACTERIZED IN HAVING A BULK DENSITY OF AT LEAST 0.6 GRAM PER CUBIC CENTIMETER WHICH COMPRISES THE STEPS OF HOMOGENEOUSLY MIXING TOGETHER (A) SOLID PARTICLES FORMED BY (1) INTIMATELY ADMIXING GRANULAR ALKALI METAL TRIPOLYPHOSPHATE, AN ALKALI METAL SILICATE HAVING A SIO2 TO ALKALI METAL OXIDE MOL RATIO OF FROM ABOUT 4:1 TO ABOUT 0.5:1, FROM ABOUT 0.1 TO ABOUT 5.0% BY WEIGHT, BASED ON THE WEIGHT OF THE MIXTURE, OF A NON-SOAP SYNTHETIC ORGANIC DETERGENT SELECTED FROM THE GROUP CONSISTING OF NON-SOAP SYNTHETIC ANIONIC SURFACE ACTIVE AGENTS AND NON-SOAP SYNTHETIC NONIONIC SURFACE ACTIVE AGENTS, AND SUFFICIENT WATER TO FORM A HOMOGENEOUS MASS CONSISTING ESSENTIALLY OF A MIXTURE OF (A) FROM ABOUT 45% TO ABOUT 65% OF HYDRATED ALKALI METAL TRIPOLYPHOSPHATE, (B) FROM ABOUT 55% TO ABOUT 30% OF AN ALKALI METAL SILICATE HAVING THE AFOREMENTIONED SIO2 TO ALKALI METAL OXIDE MOL RATIO AND SELECTED FROM THE GROUP CONSISTING OF ANHYDROUS ALKALI METAL SILICATE, PARTIALLY HYDRATED ALKALI METAL SILICATE AND MIXTURES THEREOF, (C) FROM ABOUT 0.1, TO ABOUT 5% BY WEIGHT OF A NON-SOAP SYNTHETIC ORGANIC DETERGENT SELECTED FROM THE GROUP CONSISTING OF NON-SOAP SYNTHETIC ORGANIC ANIONIC DETERGENTS AND NON-SOAP SYNTHETIC ORGANIC NONIONIC DETERGENTS, AND (D) FROM ABOUT 10% TO ABOUT 25% BY WEIGHT OF WATER IN THE FORM OF WATER OF HYDRATION IN SAID TRIPOLYPHOSPHATE AND SAID SILICATE, AND (2) FORMING SAID MASS INTO SOLID PARTICLES, AND (B) SOLID PARTICLES OF FROM ABOUT 0.5 TO ABOUT 3.0% BY WEIGHT OF THE COMPOSITION OF AN AVALIABLE CHLORINE-CONTAINING COMPOUND SELECTED FROM THE GROUP CONSISTING OF CHLORINATED TRISODIUM PHOSPHATES AND ORGANIC AVAILABLE CHLORINE-CONTAINING COMPOUNDS AND HAVING A PARTICLE SIZE SUCH THAT AT LEAST 90% OF THE LAST MENTIONED SOLID PARTICLES ARE RETAINED ON A NO. 100 MESH U.S. STANDARD SCREEN THEREBY FORMING SAID COMPOSITION.
