    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 dimensionally stable alkaline solid block warewashing detergent uses an E-form binder forming a solid comprising a sodium carbonate source of alkalinity, a metal corrosion protecting alkali metal silicate composition, a sequestrant, a surfactant package and other optional material. The solid block is dimensionally stable and highly effective in removing soil from the surfaces of dishware in the institutional and industrial environment. The E-form hydrate comprises an organic phosphonate and a hydrated carbonate.

    Abstract: Aqueous bleach solutions can be made by directing a spray of water onto a bulk or shaped solid (brick, tablet, block, etc.) comprising a continuous solid phase of an encapsulated source of an active halogen bleach or a solid comprising a source of an oxidizing active halogen bleach, and an encapsulated oxidizing halogen bleach source. Such shaped solids can be used to dispense an aqueous bleach concentrate to bleaching locus such as a washing machine.

    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.
