PURPOSE: To keep an antiseptic property effective on the wiped part and an antibacterial property preventing mold for a long time, by impregnating the base of a wiper with silver based inorganic antibacterial fine particles, using modified chitosan collagen modified with fatty acid, as a stable homogeneous dispersion for water. CONSTITUTION: An ion-exchange silver based inorganic compound, such as silver zeolite, silver phosphoric acid zirconium, silver apatite and so on, is used as silver based inorganic antibacterial chemicals. To disperse the inorganic antibacterial chemicals stably in water dispersion, a wiper, whose base is impregnated with a water dispersed liquid including a modified fusible chitosan collagen of 0.05-5% by weight produced by modifying chitosan and collagen with fatty acid, should be used for a human being. Another wiper, whose base includes silver inorganic antibacterial chemicals using a mixed liquid including protective colloid of more than 0.05% by weight, a detergent of more than 0.05% by weight, and ethylene glycol of more than 0.1% by weight in addition to the modified chitosan collagen a dispersing stabilizer, should be used as an objective wiper. |
