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.
Abstract:
A device and method for cleaning and deororizing a unit having an enclosed space not otherwise easily accessible for cleaning and doedorizing. A variety of containers holding compositions for generating an antimicrobially active gas may be employed therein. One such container includes a unitary container housing having a plurality of sealed compartments. Each compartment contains a composition for generating an antimicrobially active gas upon exposure to moist air. The container may be employed in other applications as well.

Abstract:
2099362 9213061 PCTABS00014 A process for producing a solid cast silicate-based cleaning compositions which includes the step of combining appropriate concentrations of an alkali metal silicate, an alkali metal hydroxide and a source of water to form a reaction mixture that solidifies into a reaction product which is processable at temperatures below the melting point or decomposition temperature of the reaction product. The process provides for the rapid manufacture of a solid cast alkaline cleaning composition without melting of the cast composition. Incorporation of appropriate amounts of a combination of a polyacrylate and a phosphonate into the cleaning composition cooperate with the silicate present in the composition to form a threshold system which is effective for controlling precipitation of both calcium and magnesium in a use solution.

Abstract:
A solid heavy duty laundry detergent composition having a zero phosphorus content is disclosed that has the capability of effectively conditioning service water. The detergent composition comprises a source of alkalinity, a water-conditioning vinyl polymer with pendant carboxyl groups, a water-conditioning copolymer of acrylic acid and itaconic acid, and at least one nonionic surfactant.
