These disinfectants are popular because of their effectiveness against germs, bacteria and viruses; their relatively low toxicity at proper dilution; low odors and; long shelf life. When used properly, quat disinfectants can be very effective. But if used incorrectly, quat binding can occur, drastically reducing the cleaning efficacy.
Quaternary Ammonium Compounds (QACs), often called quats, are cationic surfactants (positive charge). There are many QACs in use, but among the most discussed are the disinfectant QACs. The positive charge makes them bind to negatively charged cell walls in microbes where the QAC damages the cell walls/membranes. At concentrations …

When they get on the skin, quats are low in toxicity.2,3 This means it would take a very large amount on the skin before someone became sick or died. However, quats can be severely irritating or corrosive to the skin.2,3 The effects depend on the concentration of quats in a formula. See the text box on Technical Grade Quats.
Quat is the common name for quaternary ammonium chloride compounds. The compounds contain four organic groups - hence the quaternary part of the name.

Quaternary Ammonium cations (QAC or Quats), are a class of molecule often used as disinfectants in a variety of industries such as cheese plants. All QACs consist of a nitrogen cation bound to four separate side molecules (R1-4). QACs function by direct contact with bacteria. Their positive change and shape causes them to rip apart bacterial ...

Quaternary ammonium compounds, also called quats, are chemicals made of two basic parts. The first part is a central nitrogen atom. 1 The second part is made up of four clusters of atoms 2 that are attached to the nitrogen atom (Figure 1). The U.S. Environmental Protection Agency (EPA) currently classifies quats into four different …
Surface damage: Quats can be harsh on certain surfaces and cause damage, such as discolouration or corrosion. Preventing quat binding can help to reduce the risk of surface damage. Cost: Quats can be expensive, and preventing binding can help to reduce the amount of quat needed for a given application, potentially leading to cost …
As of 16th April 2020, List N contained 370 recommended products. Of these, 171 (48%) products contain Quats ingredients alone, and a further 33 products contain Quats formulated with at least one other class of active ingredient. Quats up to 0.2% are also among proven disinfectants suggested by the US CDC against enveloped SARS-CoV-2.
Some of the health risks associated with quats or QACs exposure are: Respiratory conditions and decreased lung function. Occupational asthma. Greater immune reaction to allergens. Worsening asthma symptoms. Decreased fertility in mice. Neural tube defects in mice. Quat resistance in livestock contributing to antimicrobial resistance.
