Product Application of Didecyl Dimethyl Ammonium Chloride CAS#7173-51-5
Didecyl Dimethyl Ammonium Chloride is a high-efficiency antimicrobial agent with broad inactivation capacity against diverse harmful microorganisms. It exerts prominent inhibitory and killing effects on common pathogenic bacteria including Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, as well as Legionella pneumophila and mold such as Stachybotrys. It is also effective against both enveloped and non-enveloped viruses, presenting comprehensive disinfection advantages.
Different from traditional single-chain quaternary ammonium salts, this double-chain structured compound delivers higher disinfection activity and stronger environmental adaptability. It can thoroughly remove bacterial vegetative cells, fungal colonies and lipophilic viruses. Meanwhile, it possesses superior water solubility and outstanding surface tension reduction ability, enabling uniform dispersion and stable efficacy in aqueous systems.
With its safe, stable and highly efficient bactericidal characteristics, the product is widely adopted for routine sanitary disinfection and epidemic prevention work. It is particularly applicable to preventive sterilization scenarios for respiratory infectious disease control, as well as various public hygiene and daily disinfection fields, serving as a reliable multifunctional disinfectant for civil and industrial sanitary management.
