The present invention relates to a method for producing an antibacterial composition including nanosilver. The antibacterial composition produced by the method of the present invention has an excellent antibacterial effect, does not have a problem of storage caused by settlement, can be produced in a simple process, and thus can be used to efficiently produce an antibacterial solution. The method for producing an antibacterial composition including nanosilver includes the following steps: dissolving silver nitrate by mixing silver nitrate with distilled water dissolving a crystallizing agent by mixing the crystallizing agent with distilled water mixing and heating the two materials and then cooling the two materials at room temperature adding a stabilizing agent to the mixture and cooling the mixture at room temperature and adding an anti-settlement agent to the mixture.COPYRIGHT KIPO 2016본 발명은 나노실버를 포함하는 항균용 조성물의 제조방법에 관한 것으로, 본 발명의 제조방법에 의하여 제조되는 항균 조성물은 항균 효과가 우수하고, 침전에 의한 보관의 문제가 발생하지 않으며, 제조과정이 간단하여, 효율적으로 항균용액을 제조할 수 있다.
