Medicated soap (English spelling)

Japanese: 薬用セッケン(薬用石鹼) - やくようせっけん（英語表記）medicated soap

A cleaning agent used primarily for disinfecting skin and wounds, and for cleaning unsanitary equipment. Although it is called a soap, it differs from so-called cleaning soaps made of sodium salts of higher fatty acids in that it has bactericidal and disinfecting properties. Representative examples include cresol soap, which is made by saponifying vegetable oil and dissolving it in cresol, formalin soap, which is mixed with an aqueous formaldehyde solution, and synthetic detergents, particularly cationic surfactants, such as cationic cationic soaps. Generally, commercially available products are supplied in liquid form.

おもに皮膚や傷口の消毒，不衛生な器具の洗浄などに用いられる洗浄剤。セッケンの名称ではあるが，いわゆる高級脂肪酸ナトリウム塩の洗浄用セッケンとは異なり，殺菌力，消毒効果をもつ点に特徴がある。植物油をケン化し，これをクレゾールに溶かしたクレゾールセッケン，ホルマリン水溶液に混ぜたホルマリンセッケン，また合成洗剤で，とくに陽イオン界面活性剤である逆性セッケンなどが代表的なものである。一般に市販品としては液状で供される。
