Provided is a disinfectant composition in which the efficacy of olanexidine gluconate, which has been used as a highly safe disinfectant for external use, is further enhanced, which has an expanded antimicrobial spectrum, and which therefore has an expanded application range. By using a disinfectant composition characterized by containing olanexidine gluconate and being basic, an olanexidine gluconate-containing disinfectant having an expanded antimicrobial spectrum compared to conventional products can be produced.本發明提供一種消毒用組合物，其藉由進一步提高用作高安全性之外皮用殺菌消毒劑之奧蘭西丁葡萄糖酸鹽之效力，且擴大抗菌譜，從而進一步擴大應用範圍。本發明藉由使用以含有奧蘭西丁葡萄糖酸鹽且為鹼性為特徵之消毒用組合物，可製作殺菌譜較先前擴大之含有奧蘭西丁葡萄糖酸鹽之消毒劑。
