Patent number: 8536399Abstract: 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.Type: GrantFiled: October 12, 2010Date of Patent: September 17, 2013Assignee: Uni-Charm CorporationInventors: Kazuki Numano, Kiy shi Miyazawa, Takayuki Hisanaka, Yozo Yamada

Patent number: 7235707Abstract: 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.Type: GrantFiled: January 22, 2003Date of Patent: June 26, 2007Assignee: Uni-Charm CorporationInventors: Kazuaki Onishi, Takayuki Hisanaka
