  • Patent number: 6503879
    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.

  • Patent number: 6472027
    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.

  • Patent number: 6361826
    Abstract: Continuous coatings are prepared using novel two part compositions and methods. The two part compositions of the invention comprise, in separate containers, a powder polymer composition and a coalescing agent. The powder composition has preferred particle size distribution and composition for use in the compositions or methods of the invention. The coalescing agents of the invention cooperate with the powder part to result in a excellent finish having the appropriate drying hardness, durability, etc. The novel method of the invention involves contacting a coalescing agent with polymer particles in a variety of coating methods. The particles and the coalescing agent interact to form a continuous coating layer or finish layer. The basic coating formation methods of the invention can be embodied in a number of methods or protocols including applying a solid polymer to the liquid coalescing agent, applying the agent to the polymer particulate or applying the liquid and polymer simultaneously.

  • Patent number: 6258765
    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.

  • Patent number: 6124250
    Abstract: The invention provides a process for preparing a highly alkaline, solid cleaning composition in a batch or continuous mixing system, at or below the melting temperature of the alkaline ingredients, and products produced by the process. Preferably, the ingredients are processed in an extruder, and the mixture is extruded directly into a mold or other packaging system for dispensing the cleaning composition. The consistency of the product ranges from that of a fused block solid to a malleable product. The highly alkaline cleaning compositions are useful for warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, laundry detergents, and the like.

  • Patent number: 5407598
    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. The presence of the encapsulate in the solid with the powder reduces the tendency of the solid to absorb water which can be wicked through the solid to pass water through the solid into adjacent solids.

  • Patent number: 5384364
    Abstract: The stability of polyvinyl films used to contain detersive systems may be enhanced by the use of a barrier coating composition to separate the film degrading components, i.e., acids, bases, and halogens, from these films. The barrier coatings may either encapsulate the individual film degrading components, or they may coat the entire detersive system.

  • Patent number: 4965012
    Abstract: A composition capable of releasing active enzyme into an aqueous, active chlorine containing media which in a first aspect comprises an enzyme core encapsulated with an initial coating of a time-release substance, a first coating of a bleach-neutralizing substance and a second coating of a time-release substance.In a second aspect, the composition comprises an enzyme encapsulated in a time-release substance designed to delay release of the enzyme in dissolution for a first-time delay, and a bleach-neutralizing substance, present as either a core material and/or a first coating on a diluent core, which is encapsulated in a time-release substance designed to delay release of the bleach-neutralizing substance into solution for a second-time delay; the first-time delay being longer than the second-time delay so that the bleach-neutralizing substance will be released and completely neutralize all active chlorine present in the solution before the enzyme is released.
