  • Patent number: 11001792
    Abstract: An improved cleaning composition in block form is described. The composition addresses the consumer issues of having a clear product that remains clear through the life of the product and also has favorable handling properties such as a high melting point and increased hardness. The improvements are the result of three essential ingredients of particular block copolymer nonionic surfactants, alkanecarboxylic salts, and particular solvents at restricted proportions in the overall composition that are molded into a cleaning composition in block form that exhibits a high melting point, hardness and high optical transmittance.

  • Patent number: 8927477
    Abstract: A sanitary agent for treatment of a sanitary appliance includes a solid or semi-solid active body, designed to adhere to a wall of the sanitary appliance and including a treatment compound having at least an active element for treatment of the sanitary appliance. The body has an external surface thereof covered by a water-soluble film. In this way, the sanitary agent can be manipulated by hand for application thereof to a moist ceramic wall of a sanitary appliance to be treated, without the user's hands entering into contact with the components of the sanitary agent itself. Furthermore, any undesired loss of the components of the sanitary agent is avoided; these can be due to deformation of the sanitary agents before use thereof, displacements thereof and/or any dripping. A method for applying the sanitary agent for deterging, disinfecting and/or perfuming the sanitary appliance is also provided.

    Abstract: A cleaning system having pulverulent foaming cleanser (e.g., acid, alkali metal carbonate and surfactant) is sealed within a water soluble (e.g., PVOH) deformable pouch frictionally retainable within the core of a roll of bath tissue. Upon placement of the pouch in the bowl, water in the bowl penetrates the water soluble wall of the pouch, generating foam which provides cleaning action by activating and carrying cleansing chemicals, not only below the water line of the bowl, but also considerably above it. When used routinely with each change of bath tissue roll, such a cleaning can extend the time between required manual cleanings considerably.

  • Patent number: 6833340
    Abstract: A method of delivery of active substances to a water-filled environment, specifically a toilet bowl, with a water-soluble polymer as the primary delivery means. The present invention is activated by placement in the water, with the soluble polymer protecting the skin from exposure to the active ingredients. The soluble polymer is composed of a bi-layer capsule or tablet, preferably, with a solid, gas, gel, or liquid core. Alkali metal particles embedded in an interior layer of the capsule or tablet react with water once an exterior layer has dissolved. The alkali metal particles elevate water temperature, especially locally to the interior layer, and volatilize active substances contained within the interior layer. The active substances are preferably deodorants. Alternatively, capsule or tablet is covered with a non-water-soluble final coating layer so that if the present invention is stored or delivered in an aqueous solution, the active substances will not be delivered until desired.

    Abstract: This invention relates to an enzymatic detergent drain cleaner composition containing:0.015-20 wt % of an acid cellulase enzyme having hydrolytic activity specific to .beta.-glucosidic bonds;1-70 wt % of a water soluble carbonate salt;1-70 wt % of a water soluble acid that reacts in an aqueous medium with the carbonate salt to form carbon dioxide that dissolves in the aqueous medium;0.1-10 wt % of a surfactant; and0.05-5 wt % of a thickening agent. This detergent composition may be used as an enzymatic detergent drain cleaner or in a method for removing or preventing bacterial cellulose deposits in an aqueous system at a solution temperature of up to about 60.degree. C. and a pH of about 2 to about 7.

  • Patent number: 5863876
    Abstract: Disclosed herein is a toilet cleansing block containing a polyacrylate polymer and a lauryl benzene sulfonate salt surfactant. The block is essentially free of other polymers that sequester ions. The block is for immersion in toilet tanks, and inhibits toilet bowl ring and stain formation, particularly those caused by iron oxide.

  • Patent number: 5756440
    Abstract: A disinfectant and cleansing composition is provided in the form of an extruded solid. The active agent in the composition is a halogen-releasing agent such as a halogenated 5,5-dialkylhydantoin. An inert binder such as a fatty acid salt or a hectoritic clay is used to enable manufacture of the composition using an extrusion process. Fragrance, colorants, and other pressure-sensitive materials may be included; fragrance and colorants are preferably incorporated in encapsulated form. Methods for manufacturing the compositions are also provided, as are methods for using the compositions in sanitizing water, particularly in disinfecting and cleansing flush toilets.
