  • Patent number: 7001875
    Abstract: Dual colorants are disclosed. The colorants of the present invention include at least one compound, which exhibits a first color outside an aqueous environment and a second color after placement into an aqueous environment. In some cases, the colorant includes an oil-soluble dye capable of exhibiting the first color and a water-soluble dye capable of exhibiting the second color. In certain embodiments, such colorants may be used in toilets. In these embodiments, the first color corresponds to a color associated with a fragrance, such as red for rose, while the second color corresponds to a color associated with cleanliness in a toilet, such as blue or green.

  • 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.

  • 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: Disclosed are disposable cleansing articles (1) which comprise a multi-phase, multi-component emulsion (5) and an activation web (2) that facilitates activation of the emulsion during use. In a preferred embodiment, the multi-phase emulsion is a high internal phase inverse emulsion having a continuous external lipid phase and a discontinuous internal polar phase. During use, the activation web facilitates breakage of the emulsion's external phase, thereby releasing the internal phase for its desired use. Because the internal liquid phase may account for up to about 97% of the emulsion, significant levels of fluid (e.g., water or a polar liquid) may be delivered from a “dry” wipe.

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.

  • Patent number: 6508954
    Abstract: Among the enhanced properties of the 1,3-dibromo-5,5-dimethylhydantoins described are their larger average particle sizes, their compactibility even though devoid of a binder, their excellent free-flowing and low-dust properties, and their more appealing aesthetic qualities, as compared to previously known 1,3-dibromo-5,5-dimethylhydantoins. These novel 1,3-dibromo-5,5-dimethylhydantoins can be produced, for example, by concurrently feeding (i) an aqueous solution or slurry formed from an inorganic base and 5,5-dimethylhydantoin, and (ii) a brominating agent, in proportions such that each nitrogen atom is substituted by a bromine atom, thereby forming product which precipitates in an aqueous reaction mixture. The pH of the reaction mixture is maintained in the range of about 5.5 to about 8.5.

  • Publication number: 20020151453
    Abstract: A multi-phase solid toilet article whose phases are separated by a membrane, and processes for making the article are described. Each phase is reproducibly fabricated to form an article allowing the user to sequentially or simultaneously derive benefits from the different materials contained in the article's layers. The membrane is either at least partially water soluble or dispersible in the case of a product used with water, or shearable in the case of a cosmetic product which is applied directly to or rubbed on the skin. The membrane material is selected to dissolve or disintegrate with product use, so as to accomplish its intended function of separating the different cosmetic materials until they are consumed. The flowable toilet or cosmetic formulations are simultaneously or separately transferred into the mold, simultaneously or separately allowed to harden, where the membrane divider is not removed and becomes a part of the finished product.
