Definitions

  • the present invention relates to an interior cleaning implement having a fibrous base material. More specifically, the present invention relates to a cleaning implement that can reduce the antigenicity of substances that can provoke allergies.
  • Priorities are claimed on Japanese Patent Applications No. 2004-262896, filed September 9, 2004, No. 2004-262897, filed September 9, 2004, No. 2004-341804, filed November 26, 2004, and No. 2004-358952, filed December 10, 2004, the contents of which are incorporated herein by reference.
  • allergens of which approximately 200 types have been discovered. Mites, dead mite parts, pet hair, and pollen are typical examples. These can provoke various allergic reactions through contact with or entry into the body. In these cases, using chemicals or the like to kill the mites and the like that provoke allergies does not provide a complete solution since the dead mite parts are also antigenic. Thus, reducing allergic reactions and preventing new sensitivities from developing requires either completely removing allergens from the living space or reducing the antigenicity of substances that provokes allergies by denaturing allergens or the like.
  • Examples of an agent for reducing antigenicity of allergy-inducing substances as described above that have been disclosed include allergen inactivating agents made from Olea europaea and/or Ligustrum obtusifolium (Japanese Patent Application Laid-open number 2003-55122, hereinafter called Patent Document 1) . Also, there have been disclosed allergen-reducing agents in forms that can be applied or dispersed in an aqueous state onto floors, carpets, and floor mats in the form of an aqueous solution containing aluminum sulfate and sodium sulfate as the active components (Japanese Patent Application Laid-open number 2003-334240, hereinafter called Patent Document 2) .
  • allergens adhere to the cleaning implement during cleaning and remain on the cleaning implement for extended periods. As described above, reducing or preventing allergic reactions would require reducing the antigenicity of the allergens on the cleaning implement.
  • Patent Document 1 and 2 are all used by applying or dispersing them directly at location that may come into contact with the body, e.g., floor mats, carpets, floors, and clothes. This makes it necessary to wipe away the agent or to remove it with a vacuum cleaner after application, resulting in a burden on the user. Easy elimination of allergy-inducing substances in the cleaning of dust and particles on floors and furniture that are cleaned most often has not been investigated. Also, since the conventional methods moisten the object being cleaned, the object must then be dried. Dry cleaning methods for reducing allergy-inducing substances have not been proposed. Furthermore, no research has been done on reducing antigenicity of allergy-inducing substances contained in dust and particles collected on dry cleaning implements such as mops.
  • interior dry cleaning implements ones which are disposable and replaceable, and equipped with fibrous base materials in sheet or brush form that contain essentially no moisture, have been well- received on the market.
  • these dry cleaning implements there is a need for the antigenicity-reducing composition to be adhesive to and permeable in the fibrous base material, and the transfer of the composition to the object being cleaned must be minimal.
  • Patent Document 1 does not take into account the adhesiveness or the permeability of the composition.
  • the allergen-reducing agent in the Patent Document 2 is meant to be used as an aqueous fluid, i.e., in a "wet" state, and is not easily applicable to a dry cleaning implement that contains essentially no moisture.

Also the antigenicity-reducing component and a lubricant can be applied easily to a "dry-type" fibrous base material.
  • dry-type cleaning implement refers to a cleaning implement containing the lubricant having a greater proportion by weight than the moisture, and a proportion of 5.0% moisture or less would be appropriate.

  • Floor-type Debris containing approximately 0.05 g of mite allergens (dust mites) and approximately 0.01 g cedar pollen were placed on a floor panel approximately 30 cm x 30 cm. The debris and the cedar pollen were wiped away with the floor-type cleaning tool. An extraction fluid was used on the cleaning tool to extract the allergens and the allergens were quantified using the ELISA method.
  • a phosphoric acid buffering agent (pH7) was used as the extraction fluid.
  • the ELISA method enzyme-linked immunosorbent assay
  • EIA enzyme immunoassay
  • the Sandwich technique that uses two kinds of antibody which sandwiches the object to be detected to quantify was used. Table 2 Cedar Pollen Antigenicity Reduction Rate
  • the fibrous base material was placed by itself in a paper housing and covered for the handy-type cleaning tools and in a pillow-type covering made from film for the floor-type cleaning tool.
  • the packages were left indoors away from direct light, in a thermostatic chamber at 40 degrees C, and in a thermostatic chamber at 50 degrees C. Then, after one month, allergens were measured using the same method as in the Evaluation Test 1.
  • the reduction effect was maintained after exposure to heat for one month.
  • the reduction effect was also maintained after exposure to sunlight.
  • Antigenicity-reducing components contained in antigenicity-reducing compositions were applied to fibrous base materials in the fourth to sixth embodiments and second comparative example. Details are described below. Using the two types of antigenicity-reducing agents used for the first to the third embodiments and the first comparative example, production examples 5 to 7 of antigenicity-reducing compositions were prepared using the proportions shown in Table 5. Also, the production example 8 was prepared as a composition without an antigenicity- reducing component.
  • Liquid paraffin and/or safflower oil were used as the lubricant.
  • the surfactant at least one of the following was used: polyoxyethylene alkyl ether, sorbitan monoester of oleic acid, mono isostearic acid glyceryl, sorbitan triester of oleic acid, and polyoxyethylene hydrogenated castor oil.
  • water was mixed in and agitated to prepare the antigenicity-reducing composition.
  • Amount of Antigenicity-Reducing Composition (units: % by weight)
  • (Olive extract) Olive plant leaves were extracted with water based on the third compound example in Patent Document 1. Ethanol was added to so as to be adjusted to 0.6% oleuropein.
  • the antigenicity-reducing composition solution examples 5 to 7 and the composition solution example 8 were sprayed onto the cleaning tool shown in Fig. 1 (hereinafter referred to as the "handy-type"), and onto the cleaning tool shown in Fig. 4 (hereinafter referred to as the "floor-type”) .

  • the floor-type cleaning tool of the fourth and sixth embodiments provided reductions of each of the antigenicity-reducing compositions.
  • the handy-type cleaning tool of the fifth embodiment not as much of the antigenicity-reducing component was applied and the effect was somewhat less.
  • Evaluation Test 2 Evaluation of reductions after exposure to heat and light
  • Results are shown in Table 8, with the reduction rates and symbols in the table indicating the same as in Tables 6 and 7.
  • the reduction effect was maintained after exposure to heat for one month.
  • the reduction effect was also maintained after exposure to sunlight.
  • the present invention is suitable for use as an interior cleaning implement having a fibrous base material.

Abstract

La présente invention a pour objet un dispositif de nettoyage d’intérieur basé sur un matériau sec fibreux. Ledit matériau est imprégné d’une préparation dont la caractéristique est d'être susceptible de réduire d'éventuelles propriétés antigéniques, et qui comprend un composé réduisant les propriétés antigéniques, ainsi qu'un lubrifiant. Dans un mode préféré de l’invention, ledit agent est un composé extrait d’une plante de type Olea ou Ligustrum, obtenu par extraction à l'eau ou à l'aide d'un solvant organique.
