  • Patent number: 6083893
    Abstract: The present invention provides a firm, mild, good performing, low-smear semi-solid or solid dishwashing product. The rheology of the dishwashing product is such that structural elements have been separated from functional elements to obtain best structure properties and in-use properties. By using an interlocking mesh of carboxylic acid and/or neutralized carboxylic acid fibers and/or platelets to provide a support structure, the semi-solid or solid dishwashing product can be loaded with superior performing dishcare materials (e.g., mild surfactants) and appearance enhancers without dependence on surfactant-water phase behavior to provide the support structure. As a result, the present dishwashing product is milder than semi-solid dishwashing products currently on the market. The support structure of the present product, and preferably the use of hygroscopic surfactants, provide a product with lower smear than current gel dishwashing products.

  • Patent number: 6001791
    Abstract: The invention concerns a liquid agent in suspension for use in washing-up machines. The aim of the invention is to ensure the consistency of a paste without the need to use thickeners or extenders. This is achieved by using 30 to 60% by weight of water, 15 to 70% by weight of an alkali-metal tripolyphosphate selected from sodium tripolyphosphate, used either in the anhydrous or the partly hydrated form, and potassium tripolyphosphate in the presence of 5 to 30% by weight of an alkali carrier such as an alkali-metal hydroxide, carbonate, or metasilicate, if necessary in the presence of active-chlorine carriers, complex carriers and the other usual auxiliaries.

  • Patent number: 5981457
    Abstract: The present invention relates to a concentrated liquid gel warewash detergent composition which contains about 5% to about 30% by weight of an alkali polyphosphate, about 8% to about 50% by weight of a source of alkalinity, about 0% to about 5% by weight of a surface active agent, about 0.1% to about 2% by weight of a hydrophilic crosslinkled polycarboxylate thickening agent, about 0.1% to about 2% by weight of a hydrogen bonding agent for the polycarboxylate, and about 0 to about 15% of a polyacrylate, the balance being water. The composition may also contain about 0% to about 3% by weight of a chlorine bleach. The composition is predissolved and can be accurately metered into warewash machines to clean and destain tablewares and dishwares.

  • Patent number: 5977054
    Abstract: Disclosed are mildly acidic liquid compositions for use in cleaning hard surfaces. The compositions contain from about 1% to about 60% of an amine oxide detergent surfactant, an aqueous carrier liquid, and an acidifying agent having a pK.sub.a of less than about 6.0. The compositions contain enough of the acidifying agent to protonate at least about 10% of the amine oxide species within the compositions and to provide a composition pH of between about 3 and 7. These no-rinse liquid hard surface cleaning compositions have excellent cleaning properties, they do not leave a visible residue when they dry, and they cause minimal or no staining of vinyl surfaces. Also disclosed are a method for cleaning vinyl surfaces using the liquid compositions, and non-liquid compositions from which the mildly acidic liquid compositions can easily be obtained by adding an aqueous liquid.
