Phenol is the standard, and the corresponding rating system is called the "Phenol coefficient". The disinfectant to be tested is compared with phenol on a standard microbe (usually Salmonella typhi or Staphylococcus aureus). Disinfectants that are more effective than phenol have a coefficient > 1. Those that are less effective have a ...
The ideal concentration for the manufacture of disinfectants is a phenol content of 15% on the product. In this way, when the disinfectant is prepared for use, it will always have a final concentration of phenols higher than 1%, which is used for cleaning and disinfection. [citation needed]
[1] [5] [6] [7]: 104 Some phenols are germicidal and are used in formulating disinfectants. Phenol – the simplest of the phenols Chemical structure of salicylic acid, the active metabolite of aspirin Chemical structure of aloe emodin, a diphenol Quercetin, a typical flavonoid, is a polyphenol Tannic acid, a typical polyphenol of indeterminate ...
some phenolic compounds, such as hexachlorophene, triclosan and Dibromol, and cationic surfactants, such as 0.05–0.5% benzalkonium, 0.5–4% chlorhexidine , 0.1–2% octenidine solutions. Others are generally not applicable as safe antiseptics, either because of their corrosive or toxic nature.
Pentachlorophenol (PCP) is an organochlorine compound used as a pesticide and a disinfectant.First produced in the 1930s, it is marketed under many trade names. [5] It can be found as pure PCP, or as the sodium salt of PCP, the latter of which dissolves easily in water.
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the ...
A chlorophenol is any organochloride of phenol that contains one or more covalently bonded chlorine atoms. There are five basic types of chlorophenols (mono- to pentachlorophenol) and 19 different chlorophenols in total when positional isomerism is taken into account. Chlorophenols are produced by electrophilic halogenation of phenol with ...
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C 6 H 5 OH. [5] It is a white crystalline solid that is volatile . The molecule consists of a phenyl group ( −C 6 H 5 ) bonded to a hydroxy group ( −OH ).
