  • Patent number: 6849590
    Abstract: The present invention relates to a process for preparing particles for supporting a surfactant, comprising a step of giving a defect to a coating film containing a water-soluble component, wherein the coating film is formed on surfaces of raw material particles; and a process for preparing detergent particles comprising a step of mixing a surfactant composition and the particles for supporting a surfactant obtained by the above process, under conditions that the surfactant composition shows a liquid state. By using the process of the present invention, there can be obtained particles for supporting a surfactant, in which the supporting ability of the particles is improved, without lowering the detergency. In addition, by using the particles for supporting a surfactant, there can be obtained detergent particles having excellent detergency.

  • 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.

  • Patent number: 6825161
    Abstract: The present invention relates to an improved controlled delivery system that can be incorporated in soap bars to enhance deposition of active ingredients and sensory markers onto skin. The carrier system also provides controlled release or prolonged release of these actives from the skin over an extended period of time. The controlled delivery system of the present invention comprises substantially free-flowing, powder formed of solid hydrophobic, positively charged, nanospheres of encapsulated active ingredients, that are encapsulated in moisture sensitive microspheres. The high cationic charge density of the nanosphere improves deposition of active ingredients onto skin.

  • Patent number: 6820626
    Abstract: An encapsulated active substance for a manual detergent for hard surfaces comprises an essentially anhydrous active substance with at least one surfactant and at least one liquid polymer carrier encapsulated in a water-soluble or water-dispersible capsule, the active substance containing: less than 25 wt. % of carrier; at least one unbranched or branched, acryclic or cyclic, saturated or unsaturated alcohol with 1 to 10 carbon atoms and one or two primary, secondary or tertiary hydroxy groups and a carbon chain optionally having one or more —O— groups; or being free of glycerol. The encapsulated active substance can be used as a manual detergent for hard surfaces.

  • Patent number: 6812202
    Abstract: The invention relates to a highly alkaline or mildly alkaline detergent composition having enhanced cleaning properties. The detergent combines a source of alkalinity and a blend of nonionic surfactants that enhances cleaning starchy soils. The blend of nonionic surfactants preferably includes an alkyl polyglycoside surfactant and a silicon surfactant having a hydrophobic silicon group and a pendant hydrophilic group. Preferably, the blend of nonionic surfactants includes a surfactant having a hydrophobic group and an ethylene oxide residue containing group and a polymer additive. A method for removing soil from an article is provided.

  • Patent number: 6812200
    Abstract: A process for coating laundry detergent or cleaning product tablets that contain builder(s) and also, if desired, further laundry detergent and cleaning product ingredients, by transporting the tablets on a conveyor belt provided with a multiplicity of apertures and forcing coating material through the conveyor belt apertures from below with a force such that the coating material forced over the conveying plane forms a surge through which the tablets are transported.

  • Patent number: 6794354
    Abstract: A continuous process for preparing granular detergent composition including a first step of dry neutralizing an acid precursor of an anionic surfactant with a particulate water-soluble alkaline material in a high speed mixer for a mean residence time of about 0.2 to about 50 seconds, thereby partly or totally neutralizing the acid precursor and producing a dry neutralized material containing the anionic surfactant, in the form of a free-flowing powder; and a second stop of agglomerating the free-flowing powder into a detergent agglomerate using an agglomeration binder. The agglomeration binder is preferably a viscous surfactant paste binder. The resulting agglomerates are dry, free-flowing, and have a substantially more narrow particle size distribution, compared to the free-flowing powder, with reduced fine particles and over-sized particles that generally are recycled.

  • Patent number: 6790821
    Abstract: A process for preparing coated detergent granules in a fluidized bed is provided. The fluidized bed is operated at a flux number of at least about 3.5 and/or a Stokes Number of greater than 1.0. Upon drying, the resultant detergent particles have improved appearance and flow properties and may be packaged and sold as a detergent material or mixed with various other detergent ingredients to provide a fully formulated detergent composition.
