Double chain quaternary ammonium salts are a commonly used class of biocides, which are compounds based on quaternary ammonium ions and have high surface activity and antimicrobial activity.
The main mechanism of action of double chain quaternary ammonium salt biocides is to achieve bactericidal, insecticidal, and weeding effects by disrupting and inhibiting the integrity of microbial cell membranes. Double chain quaternary ammonium salts can interact with lipids in microbial cell membranes, leading to membrane rupture and leakage of cell contents, ultimately leading to microbial death. This sterilization mechanism is applicable to many different types of microorganisms, including bacteria, fungi, and viruses
Double chain quaternary ammonium salts, represented by Didecyl dimethyl ammonium bromide and Distearyl dimethyl ammonium chloride, can kill various microorganisms, including bacteria, algae, spores, and viruses.
Double chain quaternary ammonium salt biocides have broad-spectrum bactericidal activity and can be used in fields such as crop protection, wood preservation, water treatment, household cleaning, and sanitation disinfection in agriculture. Due to its surfactant properties, it can also be used as an emulsifier, wetting agent, dispersant, and detergent in other industrial fields.
