Like many other disinfecting cleaners, the active ingredient in Lysol is a quaternary ammonium compound, also referred to as a QAC or quat. Lysol introduced one of the first QACs in the late 1880s ...
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
Continuous exposure to cleaning agents containing ethanolamine, [55] chloramine-T, [55] and Quaternary Ammonium Compounds (QACs) [49] was found to cause Occupational Asthma (OA) in cleaners. [55] QAC was also found to be involved in developing antimicrobial resistance. Symptoms reported were dyspnea, cough, and wheezing.
Benzethonium chloride, also known as hyamine is a synthetic quaternary ammonium salt.This compound is an odorless white solid, soluble in water. It has surfactant, antiseptic, and anti-infective properties and it is used as a topical antimicrobial agent in first aid antiseptics.
The study, which was undertaken and reported by a leading US developer, manufacturer and marketer of topical antimicrobial pharmaceuticals based on quaternary ammonium compounds, found that their own benzalkonium chloride-based sanitizer performed better than alcohol-based hand sanitizer after repeated use.

Disinfectant additives include quaternary ammonium compounds, phenol derivatives, terpene alcohols , aldehydes, and aldehyde-amine condensation products. All-purpose cleaners are usually concentrated solutions of surfactants and water softeners, which enhance the behavior of surfactant in hard water.
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]
In mice this disinfectant was found to cause infertility and birth defects when combined with Alkyl (60% C14, 25% C12, 15% C16) dimethyl benzyl ammonium chloride (ADBAC). [ 5 ] [ 6 ] These studies contradict the older toxicology data set on quaternary ammonia compounds which was reviewed by the U.S. Environmental Protection Agency (U.S. EPA ...
