  • Patent number: 5061392
    Abstract: A method of forming a paste detergent composition includes forming two separate aqueous solutions. The first aqueous solution includes an effective concentration, generally 1 to 70% of potassium tripolyphosphate. The second solution is an aqueous solution of a water soluble sodium based detergent builder preferably sodium hydroxide. These are combined and due to the effective concentrations of the potassium tripolyphosphate and the water soluble detergent builder, the viscosity of the formed detergent substantially increases relative to either of the viscosities of the first or second aqueous solutions. This provides a unique method of forming paste detergent compositions particularly for use in warewashing machines.
