Publication number: 20220249407Abstract: The present invention relates to: an aqueous (a water-soluble) antiseptic composition having improved antibacterial persistence comprising chlorhexidine or a derivative thereof and a silicon-based emulsifier; and a fabric type antiseptic comprising same. As the chlorhexidine or the derivative thereof is highly soluble and stable and well dispersed in an aqueous phase, the composition can exhibit excellent absorption efficiency when applied onto the skin and can ultimately maximize a cumulative emission amount of chlorhexidine or the derivative thereof. In addition, the use of the polyglyceryl fatty acid ester allows sustained release of chlorhexidine or the derivative thereof, thereby sustaining the antibacterial effect for a long time.Type: ApplicationFiled: June 24, 2020Publication date: August 11, 2022Applicants: HUONS CO., LTD., HUONS MEDICARE CO., LTD.Inventors: Bae Young KIM, Dong Il LEE, Eun Kyoung LEE, Min Hee KANG, Jae Min CHO, Joon Gyo OH
