Abstract

Abstract A disinfectant composition for medical use is provided that has satisfactory bactericidal effects, and that rarely causes skin damage even when used frequently. The composition comprises ethanol used for disinfection, a bactericidal agent, and an emollient, wherein said bactericidal agent is at least one selected from the group consisting of chlorhexidine digluconate, alkylpyridinium salts, and quaternary ammonium salts, and said emollient is at least one selected from the group consisting of diesters of dibasic acid, triesters of citric acid, triesters of phosphoric acid, polyoxyethylene glyceride of higher fatty acid, and polyglycerol.
