    Abstract: Solid block alkaline detergent compositions are disclosed comprising a source of alkalinity, and other detergent additives including sequestrants. The solid block detergents of the invention used a mixed inorganic and organic sequestrant composition that successfully softens service water used in manufacturing aqueous detergents from the composition, but also obtains substantially improved organic soil removal on dishware or flatware. The solid block detergents of the invention comprise large masses of the chemical ingredients having a weight of greater than about 500 grams in a solid block product format that is typically dispensed using a spray on water dispenser that creates an aqueous concentrate that is used in a washing machine.

    Abstract: The invention provides a process for preparing a homogeneous, urea-based, solid cleaning composition, without the application of heat from an external source to melt the urea. Cleaning compositions for use in warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, and the like, made by the method are also provided. Preferably, the ingredients are processed in an extruder, and the mixture is extruded directly into a mold or other packaging system for dispensing the detergent. The consistency of the composition ranges from that of a fused solid block to a malleable article.

    Abstract: The invention includes a process for manufacturing an improved solid cast alkaline composition, that includes (a) reacting an alkali metal silicate with an alkali metal hydroxide of the formula MOH, where M is an alkali metal, in an aqueous environment to form a reaction product; and (b) solidifying the reaction product in a mold where the reaction product is formed and solidified at room temperature without the addition of externally supplied heat and the reaction product solidifies without the use of external cooling; and where the relative amount of alkali metal silicate, alkali metal hydroxide and water incorporated into the composition are effective for producing a reaction product having about 20 to 50 parts water per 100 parts of a combination of the alkali metal silicate, the alkali metal hydroxide and water in the cast solid composition and an M2O:SiO2 ratio of about 2.5:1 to 4.0:1 and M is an alkali metal; and where the process does not result in the deactivation of desirable operative cleaning components.
