A bactericide or bacteriocide, sometimes abbreviated Bcidal, is a substance that kills bacteria. Bactericides are disinfectants, antiseptics, or antibiotics.〔Klaus Grünewald: ''Theorie der medizinischen Fußbehandlung 1: Ein Fachbuch für Podologie''. 3. Auflage. Verlag Neuer Merkur GmbH, 2006, ISBN 3-929360-60-8, S. 232 ((Digitalitat ))〕 ==Bactericidal disinfectants== The most used disinfectants are those applying *active chlorine (i.e., hypochlorites, chloramines, dichloroisocyanurate and trichloroisocyanurate, wet chlorine, chlorine dioxide, etc.), *active oxygen (peroxides, such as peracetic acid, potassium persulfate, sodium perborate, sodium percarbonate, and urea perhydrate), *iodine (povidone-iodine, Lugol's solution, iodine tincture, iodinated nonionic surfactants), *concentrated alcohols (mainly ethanol, 1-propanol, called also n-propanol and 2-propanol, called isopropanol and mixtures thereof; further, 2-phenoxyethanol and 1- and 2-phenoxypropanols are used), *phenolic substances (such as phenol (also called "carbolic acid"), cresols sutch as thymol, halogenated (chlorinated, brominated) phenols, such as hexachlorophene, triclosan, trichlorophenol, tribromophenol, pentachlorophenol, salts and isomers thereof), *cationic surfactants, such as some quaternary ammonium cations (such as benzalkonium chloride, cetyl trimethylammonium bromide or chloride, didecyldimethylammonium chloride, cetylpyridinium chloride, benzethonium chloride) and others, non-quaternary compounds, such as chlorhexidine, glucoprotamine, octenidine dihydrochloride etc.), *strong oxidizers, such as ozone and permanganate solutions; *heavy metals and their salts, such as colloidal silver, silver nitrate, mercury chloride, phenylmercury salts, copper sulfate, copper oxide-chloride etc. Heavy metals and their salts are the most toxic and environment-hazardous bactericides and therefore their use is strongly discouraged or prohibited *properly concentrated strong acids (phosphoric, nitric, sulfuric, amidosulfuric, toluenesulfonic acids) and *alkalis (sodium, potassium, calcium hydroxides), such as of pH < 1 or > 13, particularly under elevated temperature (above 60 °C), kills bacteria. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「bactericide」の詳細全文を読む スポンサード リンク
