Process of making heat dried detergent compositions containing form ii sodium triphosphate

Claim 1

IN THE PROCESS OF MANUFACTURING A HEAT DRIED DETERGENT COMPOSITION SUBSTANTIALLY FREE OF DUST AND OF STICKNESS AND CAKING PRPERTIES, THE STEPS OF INCORPORATING FORM 22 SODIUM TRIPHOSPHATE IN A FLUID MIXTURE CONTAINING ESSENTIALLY AN ORGANIC DETERGENT OF THE GROUP CONSISTING OF ALKALI METAL SOAPS AND WATER SOLUBLE NONSOAP SYNTHETIC DETERGENTS AND MORE THAN SUFFICIENT WATER TO EFFECT SUBSTANTIALLY COMPLETE HYDRATION OF THE SAID TRIPHOSPHATE TO THE HEXAHYDRATE, THE AMOUNT OF SAID TRIPHOSPHATE INCORPORATED BEING IN EXCESS OF THE AMOUNT OF DETERGENT; AGITATING AND AGING THE MIXTURE WITHIN THE TEMPERATURE RANGE OF 120* TO 200* F. FOR AT LEAST ONE HOUR AND UNTIL HYDRATION TO THE HEXAHYDTRATE IS SUBSTANTIALLY COMPLETE AS DETERMINABLE BY MEASURING THE TIME REQUIRED TO REACH A MAXIMUM IN A MASS VISCOSITY TEST OF A LIKE MIXTURE OF SAID COMPONENTS, BUT NO LONGER THAN THAT TIME REPRESENTED BY THE POINT ON THE CURVE IN FIGURE 1 WHICH CORRESPONDS TO 10 PER CENT REVERSION OF THE TRIPHOSHPATE AT THE AGING TEMPERATURE EMPLOYED; AND HEAT DRYING THE AGED MIXTURE TO THE SOLID FORM.
