QAS⁺ Long-Lasting Antibacterial and Deodorizing Liquid
QAS+ employs a unique chelation technology with positively charged quaternary ammonium salt molecules ("Quaternary Ammonium Salt-QAS"). It remains clear at low temperatures, is benzene-free, and alcohol-free. An efficient reagent in antimicrobial and deodorization.
During the epidemic, quaternary ammonium salts were designated by the Taipei City Government for use in epidemic prevention hotels due to their advanced and rapid response and prolonged antimicrobial effects.
According to the "American Chemical Society" and the "World Health Organization Disinfection Guidelines," QAS+ demonstrates over 99.9% antibacterial efficacy against "coronaviruses," "noroviruses," and "intestinal pathogens" at extremely low concentrations (effective concentration = 0.25%), with the antimicrobial capability lasting up to three days.
Sterilization rate R(%) reaches 99.9%

72-hour long-lasting antimicrobial certification test passed.



QAS⁺ Features:Safe, Stable, Long-lasting
- The long-chain quaternary ammonium salt molecules produced by special chelation technology can quickly capture and physically destroy pathogens, avoiding the issue of drug resistance.
- Preparation is convenient and rapid, requiring no personnel control or protective equipment. It can be applied using backpack or handheld sprayers, misters, or foggers in both acidic and alkaline environments.
- Biodegradable, unaffected by water hardness, environmentally friendly, and non-destructive to the Earth.
Ideal for commercial use :
QAS⁺ at low concentrations for maximum effectiveness
Low concentrations provide rapid and effective antibacterial action without environmental pollution or irritation to living organisms, making it more economically efficient.
Due to its non-corrosiveness and lack of irritation, no environmental personnel control or biological contamination measures are needed during operation. Workers only need to bring a bottle of QAS+ concentrate and dilute it on-site.
Applicable with backpack or handheld sprayers, misters, and foggers, and suitable for both acidic and alkaline environments. Excellent biodegradability is unaffected by water hardness, environmentally friendly, and non-destructive to the Earth.
After completion of the operation, customers can immediately resume work, ensuring uninterrupted factory production and unaffected office work.

Applicable Places and Case Studies
Safe for use in personal hygiene, environmental deodorization, surgical instruments, food containers, factories, and livestock farms.
