Quaternary Ammonium Compounds
(QACs or Quats)
Quaternary ammonium compounds are fairly complex chemicals in which nitrogen is bound to four organic groups. The positively charged cations in the compounds bind with the acidic phospholipids in the microbial cell wall.This action blocks the uptake of nutrients into the microbial cell and prevents the discharge of waste. In general, QACs are effective against a wide range of microbes, although the spore phase is unaffected. At lower concentrations, Gram-positive bacteria are more sensitive to QACs than Gram-negative bacteria.10 QACs are formulated in many different variations for specific situations.
QACs may be applied at concentrations varying from about 100 ppm to 400 ppm. As sanitizers, QACs are commonly applied at 200 ppm to food contact surfaces, and the solution is allowed to dry. Once dry, a residue of the QAC compounds remains and provides germicidal activity until degradation occurs. QACs also can function as detergents when present in high concentration because the compounds possess both hydrophilic and lipophilic chemical groups.
QACs are usually odorless, nonstaining, noncorrosive and relatively nontoxic to users. They function well over a broad temperature range and a wide pH range, although activity is greater at warmer temperatures and in alkaline situations. While QACs tolerate light organic loads, heavy soil will decrease QAC activity significantly. Some QACs may not function adequately in hard water, but others are formulated with added chelating agents that allow such use.
While QACs do combine with organic compounds and are discharged into the environment, the concentrations are low and heterotrophic bacteria are not negatively impacted. Soil-inhabiting bacteria such as Pseudomonas spp. andXanthomonas spp. can degrade QACs. In addition, the low amounts of QACs flowing into commercial sewage treatment facilities appear to combine with the anionic surfactants present to form complexes that reduce or eliminate toxicity.

AND
PRODUCTION PROCESS
MANUFACTURING PROCESS OF QAC DISINFECTANTS is not very complicated. For the production, there is need usable and tried a formulation, raw materials and mixing tank. For raw materials to be used, quantities to be used and ingredients usage rankings, you should look into this formulation. Therefore, formulation and productıon methods of quaternary ammonium compounds disinfectant solutions are important. If you have not a good formulation, you cannot make healthy and efficient production of any disinfectant products and derivatives.
