Description

  INDUSTRIAL APPLICABILITY The present invention can reduce not only the bactericidal properties against bacteria and molds, virus inactivation effect, but also traces of wiping after wiping even in a high alkaline area, and the antibacterial durability, antiviral durability, effective disinfectant component The present invention relates to a cleaning sheet which suppresses the reduction of the amount and the color change of the substrate sheet, and exhibits the excellent germicidal property even against drug-resistant spores.

  A so-called wet sheet (cleaning sheet) in which an aqueous solution containing a disinfectant or the like is impregnated into a non-woven fabric is simple and easy to use, and can be disposable, so a clean one can always be used. It is used in food factories, kitchens, and environment maintenance in medical facilities.

  Patent Document 1 discloses an antimicrobial agent composition in which ε-polylysine and / or a salt thereof, an electrolyte having a pH buffering capacity, and an amino acid are blended, and an antimicrobial sheet-like article using the same.

  Patent Document 2 discloses a wiping sheet impregnated with a cleaning agent containing water, a sterilizing preservative, a water-soluble moisturizer, and, optionally, a solubilizer.

  Patent Document 3 discloses cleaning water impregnated with an aqueous impregnating solution in which the aqueous impregnating solution contains a silicone or oil-based perfume forming a peelable silicone film, and part or all of the silicone or oil-based perfume is contained as an aqueous emulsion. Soluble wet sheets are disclosed.

  Moreover, as a disinfecting agent impregnated in a cleaning sheet, one containing a quaternary ammonium salt surfactant is known, and Patent Document 4 discloses a mixture of polyaminopropyl biguanide and a quaternary ammonium salt. Discloses a water-soluble composition for impregnating a fibrous sheet of pH 3.5-4.5 comprising sodium benzoate, citric acid, disodium ethylenediaminetetraacetate, a nonionic surfactant and water.

  However, the cleaning sheets described in Patent Documents 1 to 3 are not sufficient in their ability to eliminate germs against drug-resistant spores and to have antiviral persistence.

On the other hand, a disinfectant containing a quaternary ammonium salt as described in Patent Document 4 is excellent in the disinfecting effect, but when it is impregnated into a base sheet such as a non-woven fabric, the fibers of the base sheet are impregnated. The strong adsorption results in a decrease in the effective amount of the sterilizing agent component, and there is a possibility that the sterilizing property and the sterilizing persistence may be reduced unless the amount of the sterilizing agent impregnated is increased. When the substrate sheet is made of regenerated fibers, particularly fibers containing rayon, the substrate sheet becomes hydrophilic, and therefore the amount of impregnation of the disinfectant mainly composed of water can be increased, but rayon Since the adsorptivity of the active ingredient of the disinfectant is higher than that of other fibers, the amount of the active ingredient and the pH in the disinfectant impregnated in the substrate sheet is significantly reduced, and the disinfectant is impregnated in the substrate sheet. Even if the amount of the agent increases, it is difficult to sufficiently improve the bactericidal activity and its persistence, and it is also difficult to improve the antiviral property of the substrate sheet.
Moreover, although pH improvement is made more alkaline, the eradication property improvement is recognized, However, There existed a subject to which the wipe mark after wiping increases.

  Therefore, the problem to be solved by the present invention is not only the bactericidal property against bacteria and mold, the inactivation effect of the virus, but also the wiping trace after wiping can be reduced even in a high alkaline region, and the antibacterial persistence and antiviral An object of the present invention is to provide a cleaning sheet which has durability and does not have the possibility of reducing the bactericidal effect or the virus inactivating effect when impregnated into a substrate sheet.
