  • Patent number: 6653266
    Abstract: A solid functional material comprises a functional agent such as a cleaning composition, a sanitizing agent, where a rinse agent, etc. in a solid block format. The solid block is formed by a binding agent that forms the active ingredients into a solid block. The binding agent comprises a phosphonate or amino acetate sequestrant, a carbonate salt and water in an E-Form hydrate. These materials at a specific mole ratio form a novel binding agent that can form functional materials into a solid matrix form.

  • Publication number: 20030204003
    Abstract: Continuous coatings including floor finishes can be prepared using novel two part compositions and methods. The two part compositions comprise a solid particulate polymer part and a liquid coalescing agent part. A novel method of the invention involves contacting the coalescing agent with the polymer in a variety of coating methods including applying the polymer to the coalescing agent, applying the coalescing agent to the polymer or applying the coalescing agent and polymer simultaneously. The polymer and coalescing agent interact to form a continuous coating layer or finish layer.

  • Publication number: 20030162682
    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.

  • Publication number: 20030148911
    Abstract: A pseudo-stable phase-splitting solvent composition that forms a single liquid phase when subjected to mild agitation and retains that single phase while the composition is applied to a surface, but which forms two or more laminar liquid phases promptly after being applied. A concentrated solvent film forms on the surface, under a film containing the other phase. The solvent preferably is denser than water, and the composition preferably is diluted with water. This enables the solvent to attack the surface at near full strength, and provides a water seal over the solvent film.

  • Patent number: 6589443
    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 uniform quantities of an aqueous bleach concentrate to bleaching locus such as a washing machine. The tablets can be made from the encapsulated bleach or from a powder mixture of a particulate, granulated or powdered unencapsulated source of active oxidizing bleach and an encapsulated source of active oxidizing bleach by forming the powder mixture into a desired shape. Such a shaped solid bleach can be packaged in a container and can then be contacted with an aqueous spray in a dispenser to create a solution of active bleach for cleaning bleaching processes.

  • Publication number: 20030031801
    Abstract: A UV cured floor finish can be removed from a floor by applying to the cured finish an inhomogeneous stripper composition containing at least one polar solvent, allowing the stripper composition to contact the finish for sufficient time to soften the finish, and removing the softened finish from the floor by mopping, vacuuming, mild abrasion or other measures that do not remove substantial portions of the floor. Preferably the polar solvent is denser than water and preferably the stripper composition has a diffusion rate through the cured finish greater than about 7×10−7 g/cm2/sec. Strippable floor finish kits can be manufactured by combining a UV curable floor finish composition and an inhomogeneous stripper composition containing at least one polar solvent.
