Abstract: PURPOSE: An antibacterial cosmetic composition containing low molecular alginate, fucoidan, and silver-alginate is provided to safely ensure antibacterial activity and antioxidation effects. CONSTITUTION: An antibacterial cosmetic composition contains low molecular alginate having a molecular weight of 150 kDa or less; low molecular fucoidan having a molecular weight of 35 kDa or less; low molecular silver-alginate having a particle size of 0.1-3.4 um. The low molecular silver-alginate is prepared by adding 1.5-4.5 weight% of hydrogen peroxide to a solution containing 0.1-2.0 weight% of alginate; irradiating an electron beam to the mixture solution at 1.0-3.0MeV; adding a silver nitrate(AgNO_3) solution; and collecting precipitate. The cosmetic composition is manufactured in the form of skin lotion, skin softener, skin toner, astringent, lotion, milk lotion, moisture lotion, cleansing foam, cleansing lotion, body lotion, or body cleanser.
