    Abstract: A cleansing composition is described. The cleansing composition generally contains an antimicrobial agent, a heating agent, and a thermochromic agent. During use, the heating agent heats the composition so that the antimicrobial agent becomes more effective. The thermochromic agent, on the other hand, changes the color of the composition as it is heated in order to indicate to a user that the composition is at a desired temperature. In an alternative embodiment, instead of containing a heating agent, a heating source can be used to heat the composition. The heating source can be, for instance, an electrical resistance heater.

  • Patent number: 6916771
    Abstract: A composition is provided comprising two liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent and a second liquid preferably includes a peroxygen agent. The first liquid is thickened to a specified rheology, resulting in the generation of a highly effective foam. As the two liquids are initially separated, the hypohalite generating agent can be maintained in an environment free of peroxygen agent and otherwise conducive to their cleaning activity and stability up to the time of use. When the two liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas. As foam generation occurs, the escaping gas contacts surfactant in the solution, and creates foam which expands to completely fill the drain pipe.

    Abstract: The invention provides a method for increasing the brightness retention of a laundered fabric after numerous washing cycles by adding to an aqueous wash liquor a quantity of a commercial laundry detergent which delivers at least 0.1 g of an optical brightener into said wash liquor, said optical brightener exhibiting instability in the presence of hypochlorite; and prior to, concurrent with, or after the commercial laundry detergent, adding a bleaching composition in an amount of at least about 0.5 g/L. The bleaching composition contains about 2.5-10% alkali metal hypochlorite; about 0.05-5% of a bleach stable surfactant bearing at least one nitrogen atom; a bleach stable anionic surfactant or a hydrotrope, wherein the ratio of (ii) to (iii) is between about 10:1 to about 1:10; and an effective amount of a source of alkalinity.

  • Patent number: 6306219
    Abstract: The present invention is in the field of liquid or gel detergents. More specifically, the invention relates to a method for removing stains and/or odors and for disinfecting plastics, and other substrates by applying a liquid or gel detergent composition to the substrate and subjecting the substrate to microwaves. This method provides enhanced cleaning and improved stain removal on plastics, and other substrates. These cleaning compositions include a bleaching agent, preferably diacyl peroxide in a liquid or gel detergent formulation. These compositions in combination with the method of microwaving are also very effective in disinfecting and deodorizing substrates.

  • Patent number: 6297209
    Abstract: Sequestering agents for use as a whitening and fabric strength enhancer for aqueous hypochlorite bleach compositions are provided. It was found that the sequesterants when used with hypochlorite in the presence of soluble heavy metal ions, particularly iron and manganese ions, provide significantly improved whitening and fabric protection. Most preferably, the sequesterants are selected from polyacrylic acid, a polyacrylic acid derivative, a copolymer of acrylic acid or methacrylic acid and a comonomer which is maleic acid or maleic anhydride and mixtures thereof.

  • Patent number: 6294511
    Abstract: The present invention provides an abrasive-free cleaning composition which includes, in aqueous solution, a bleach, a colloidal thickener, and a source of divalent ionic calcium. The composition further includes at least one surfactant which is effective to provide cleaning activity and, in association with the colloidal thickener, thickening. The composition also includes an electrolyte/buffer which is effective to promote an environment in which the thickener and the surfactant associate to provide proper thickening. The inventive cleaning composition, with its ionic calcium source, has desirable viscosity and rheological properties, and demonstrates significant viscosity stability, rheological stability, phase stability and bleach stability. The cleaning composition maintains these desirable properties under typical storage conditions as well as over extended times and at elevated temperatures.
