Nitromersol (metaphen) is a mercury-containing organic compound that is primarily used as an antiseptic and disinfectant. It is a brown-yellow solid that has no odor or taste, does not irritate the skin or mucous membranes, and has no impact on rubber or metallic instruments, including surgical and dental tools. [1]
A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. [1] Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores ; it is less effective than sterilization , which is an extreme physical or chemical process that kills all types of life.

Cetrimide, or alkyltrimethylammonium bromide, is an antiseptic which is a mixture of three quaternary ammonium compounds: tetradonium bromide (TTAB or MITMAB), cetrimonium bromide (CTAB), and laurtrimonium bromide (DTAB or LTAB). [1] It was first discovered and developed by ICI and introduced under the brand name Cetavlon. [2]
p-Chlorocresol, or 4-chloro-3-methylphenol (ClC 6 H 3 CH 3 OH), also known as p-chloro-m-cresol, is a potent disinfectant and antiseptic. [1] It appears as a pinkish white crystalline solid. [2] It is also used as a preservative [3] in cosmetics and medicinal products for both humans and animals. It is used as an active ingredient in some ...
alcohols with or without antiseptic additives, used mainly for skin antisepsis, weak organic acids such as sorbic acid, benzoic acid, lactic acid and salicylic acid; 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 ...
The Rideal–Walker test was widely used, but the test conditions chosen were unrealistic, and impossibly high values for the coefficient were claimed by disinfectant manufacturers. Distinguished bacteriologist Sir Ashley Miles, reviewing the subject, described the test as "...at best a grossly over-simplified answer to a difficult problem and ...
Depending on their application, bacteriostatic antibiotics, disinfectants, antiseptics and preservatives can be distinguished. When bacteriostatic antimicrobials are used, the duration of therapy must be sufficient to allow host defense mechanisms to eradicate the bacteria.
