Quaternary Ammonium Salts are a neutral pH germicidal / virucidal and detergent for use in households.
QAS disinfects, cleans, and deodorizes the following hard, nonporous, inanimate surfaces: floors, walls, metal surfaces, stainless steel surfaces, glazed porcelain, plastic surfaces (such as polypropylene, polystyrene, etc.).
Active Ingredient (QAS)
Quaternary ammonium salts 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. QACs are formulated in many different variations for specific situations. Interestingly, QAS is biodegradable by oxygen and sunlight UV and is converted into food for soil microbes – what is poison to microbes and viruses becomes nitrogen food for lower food chain life forms.
What About Bleach?
On the other hand, bleach is a dilution of sodium hypochlorite which binds to organic molecules most indiscriminately and oxidizes metals rapidly. Its overall effectiveness, low cost and ease of manufacturing make hypochlorites the most widely used sanitizers. Sodium hypochlorite is a strong oxidizer and causes broad cellular mortality by damaging the outer membrane, likely producing eventual lysis of the cell. In addition, these compounds inhibit cellular enzymes and destroy DNA. Spores, however, are resistant to hypochlorites, as the spore coat is not susceptible to oxidation except at high concentrations and elevated temperatures. Other disadvantages of hypochlorites are corrosiveness to metals, health concerns related to skin irritation and mucous membrane damage and environmental contamination. The latter is of concern as chlorine can combine with organic substances to form toxic chlorinated compounds, such as trihalomethanes and dioxins. Hypochlorite use may be further restricted in the future. Care must be taken when cleaning hypochlorite spills as organic materials such as cloth, sawdust and paper may spontaneously combust upon drying!
