PURPOSE: A method for manufacturing a composition for antibacterial, antifungal, and antiviral activities is provided to decompose volatile organic materials and odor materials and prevent novel swine-origin influenza A(H1N1) virus. CONSTITUTION: A method for manufacturing a composition for antibacterial, antifungal, and antiviral activities comprises: a step of reacting a first alcohol containing a dispersion stabilizer and a silver precursor to prepare silver colloid solution; and a step of adding titanium precursor, second alcohol and acid catalyst to solution in which silver colloid solution is diluted with water to prepare a titanium dioxide nanoparticle. The composition contains 0.0000005-10 weight parts of silver colloid, 0.0000001-15 weight parts of titanium nanoparticle, 0.00001-6 weight parts of dispersion solubilizer and 55-99 weight parts of water. The silver precursor is silver nitrate(AgNO3) or silver acetate(CH3COOAg). The dispersion stabilizer is lysolecithin, flavonoid, Tween 20, Tween 40, Tween 80, polyvinylpyrrolidone or polyvinylalcohol. The titanium precursor is TTIP(titaniumtetraisopropoxide), TEOT(titaniumethoxyorthotitanate), or TBOT(titaniumbutoxyorthotitanate). |
