  • Patent number: 8536399
    Abstract: The object of the present invention is to provide a method of reducing the odor of urine; and an article functioning to reduce the odor of urine. The present invention relates to the method comprising using a compound(s) reactive with aldehydes to thereby reduce the urine odor. Moreover, the present invention relates to the article, especially one for body fluid absorption, which functions to reduce the odor of urine by having compounds reactive with aldehydes to be present in absorption articles. As the compounds reactive with aldehydes, organic amines, organic amine salts, compounds producing organic amines by the reaction with discharges, organic amines, amide compounds, and compounds having a mercapto group can be used.

  • Publication number: 20110160685
    Abstract: A liquid-permeating sheet (17) having an antibacterial-containing polymer coating part (31) disposed on the side opposite to the skin side is bonded to a back waist area of a diaper base. When a wearer sweats, the sweat penetrates the antibacterial-containing polymer part (31) through the liquid-permeating sheet (17). The antibacterial contained in the antibacterial-containing polymer containing, part (31) then comes into the sweat to inhibit the propagation of Staphylococcus epidermidis.

  • Patent number: 7235707
    Abstract: An absorbent article contains a hydrophilic fiber processed by a water-soluble deodorant containing a graft polymer having a deodorant functional group. This constitution ensures to have large deodorizing function per unit weight, compared to a particulate deodorant. Consequently, the constitution allows to decrease a weight of the deodorant and to excel in deodorizing function. Moreover, it is unnecessary to fix the deodorant and easy to compound with the absorbent article. Therefore, it allows to obtain an absorbent article having excellent aesthetics and cleanness.
