The advantages of quaternary ammonium compounds include the fact that they can kill a wide variety of microbes and are easy to use. Advantages. NO. They are widely known to be bioactive and have a high antimicrobial activity. While increases in tolerance to QACs have been observed, there is no clear evidence to support the development of … The R groups may also be connected. Unlike the ammonium ion and the primary, secondary, or tertiary ammonium cations, the quaternary ammonium cations are permanently charged, independent of the pH of their solution. They are generally non-toxic and non-allergic in nature. Quats (quaternary ammonium compounds) are potent disinfectant chemicals commonly found in disinfectant wipes, sprays and other household cleaners that are designed to kill germs. Availability The widespread availability and relatively low price of quaternary ammonium is one of its biggest advantages. Typically, quats do not exhibit efficacy against difficult-to-kill nonenveloped viruses such as norovirus, rotavirus, or poliovirus. They also tested several other quaternary ammonium compounds (Quats) which are often found in disinfectants. 1.34 for the chemical structure), are a large group of related compounds. This is largely because products formulated with QACs are readily available and versatile. These products act as dispersant agents and aid in water clarification as they assist in the coagulation of small particles. 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. Quaternary ammonium compounds (QACs) are widely used in disinfection of water, surfaces and instruments as well as in textile, leather and food industries because of their relatively low toxicity, broad antimicrobial spectrum, non-volatility and chemical stability. Advantages. The Barquat ® PQ and PQ-2 products are non-foaming cationic polymeric quaternary ammonium algaecides.
