==Disinfectants==
The most used  [[disinfectant]]s are those applying
*active [[chlorine]] (i.e., [[hypochlorite]]s, [[chloramine]]s, [[sodium dichloroisocyanurate|dichloroisocyanurate]] and [[trichloroisocyanurate]], wet chlorine, [[chlorine dioxide]], etc.),
*active [[oxygen]] ([[peroxide]]s, 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-phenoxypropanol]]s are used),
*[[phenols|phenolic substances]] (such as [[phenol]] (also called "carbolic acid"), [[cresol]]s such as [[thymol]], halogenated (chlorinated, brominated) phenols, such as [[hexachlorophene]], [[triclosan]], [[trichlorophenol]], [[tribromophenol]], [[pentachlorophenol]], salts and isomers  thereof),
*[[cationic surfactants]], such as some [[quaternary ammonium cation]]s (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 [[oxidizer]]s, such as [[ozone]] and [[permanganate]] solutions;
*[[heavy metals]] and their salts, such as colloidal [[silver]], [[silver nitrate]], [[Mercury(II) chloride|mercury chloride]], [[organomercury|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
* strong [[acid]]s (phosphoric, nitric, sulfuric, amidosulfuric, toluenesulfonic acids), pH < 1, and
*[[alkali]]s (sodium, potassium, calcium hydroxides), such as of pH > 13, particularly under elevated temperature (above 60&nbsp;°C), kills bacteria.
