QACs also interact with intracellular targets and bind to DNA. Quaternary ammonium compounds are positively charged polyatomic ions of the structure NR 4+ with R being alkyl or aryl groups. For more information, read our Disinfectants: FAQ for consumers. Quats (quaternary ammonium compounds) are potent disinfectant chemicals commonly found in disinfectant wipes, sprays and other household cleaners that are designed to kill germs. Disinfectants containing ≥ 70% alcohol, quaternary ammonium compounds (such as benzalkonium chloride) or diluted household bleach (including products containing sodium hypochlorite) are suitable for use. COVID-19 is an enveloped virus, which means it has an outer membrane. They can play an important role in infection control. Irritation: Quaternium-15 is a known human skin toxicant and allergen and possible eye irritant. They are bactericidal, fungicidal and virucidal. A common characteristic of these synthetic compounds is that one of the R’s is a long-chain hydrophobic aliphatic residue. Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005 They are synthetic organically tetrasubstituted ammonium compounds, where the R substituents are alkyl or heterocyclic radicals. This means the quats chain carries a positive (plus) charge on one end of the molecule; many soils and soaps/detergents carry an anionic or negative (minus) charge. Pol… A quaternary-based, cleaner and disinfectant concentrate. The quats are ammonium compounds in which four organic groups are linked to a nitrogen atom that produces a positively charged ion (cation). Enter a search term or phrase to search our site content. keep in mind that hospital grade disinfectants with claims against viruses, and products intended to be used to clean or disinfect medical devices, should be listed on the Australian Register of Therapeutic Goods (ARTG). © 2003 by Saunders, an imprint of Elsevier, Inc. The basic chemical structure of ammonium is a nitrogen atom with four hydrogen atoms attached around it. The Government of Canada recognizes that maintaining an up-to-date inventory of substances in commerce is critical to informing risk assessment and risk management programs and activities. Quats can also bind with, or be absorbed by, materials and fibers including cotton (e.g., cleaning rags and mops). Quaternary ammonium compounds are nitrogenous organic compounds used as disinfectants in restaurants, hospitals and homes. Ammonium quaternary compounds “quats” are active ingredients found in such products as disinfectant sprays, all-purpose antibacterial cleaners and disinfectant cleaning wipes. Enveloped viruses are relatively easy to kill compared to non-enveloped viruses, as the outer layer is easily damaged by most environmental disinfectants, provided the disinfectant is used in accordance with label directions. Quats are linked to reproductive harm, potentially affecti… Quaternary ammonium compounds (commonly known as quats or QACs) are cationic surfactants (surface active agents) that combine bactericidal and virucidal (generally only enveloped viruses) activity with good detergency and, therefore, cleaning ability. Disinfects in 3 minutes. The quaternary ammonium compounds (or quats) are a family of low-level disinfectants (according to Spaulding) with most quats being derived from benzalkonium. Evidence presented in animal and human studies show that other quaternary ammonium compounds may lead to contact dermatitis. It is non hazardous compared to other disinfectants like Sodium Hypochlorite etc. The quaternary ammonium compounds are widely used as disinfectants. Quaternary ammonium cations, also known as quats, are positively charged polyatomic ions of the structure NR 4, R being an alkyl group or an aryl group. Current concern that the increased use of such biocides in consumer products might contribute to the emergence of antibiotic resistance has led us to examine the effects of a QAC-containing domestic cleaning fluid on the population dynamics and antimicrobial susceptibility … A quaternary-based aerosol for disinfecting pre-cleaned surfaces.

These compounds can also exhibit a bactericidal effect. But in the last 10 years, scientists have linked quats to reproductive and developmental problems in animals, and found they can disrupt key cellular processes. Unlike the ammonium ion (NH 4) and the primary, secondary, or tertiary ammonium cations, the quaternary ammonium cations are permanently charged, independent of the pH of their solution. One particular ingredient that has received more attention recently as a cause of asthma is the class of chemicals known as quaternary ammonium compounds (QACs). 287-089-1.

Quaternary Ammonium Compounds Quaternary ammonium cations, also known as quaternary ammonium salts, quaternary ammonium compounds or "Quats", are salts of quaternary ammonium cations with an anion. Quaternary ammonium compounds (QACs) are widely used as adjuncts to hygiene in domestic cleaning products. It is recommended that disposable gloves are worn when cleaning and disinfecting surfaces. quaternary ammonium compounds Compounds in which the four hydrogen atoms of the ammonium radical are replaced by organic radicals. The quaternary ammonium compounds (or quats) are a family of low-level disinfectants (according to Spaulding) with most quats being derived from benzalkonium.
