Product Application of Didecyl Dimethyl Ammonium Chloride (CAS# 7173-51-5)
Didecyl dimethyl ammonium chloride delivers potent bactericidal efficacy against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Legionella pneumophila, Stachybotrys, as well as enveloped and non-enveloped viruses. Compared with single-chain quaternary ammonium salts, it achieves marked improvements in bactericidal performance and resistance to interfering factors. It excels at eliminating bacterial propagules, fungi and lipophilic viruses. Featuring excellent water solubility and outstanding surface tension reduction, it is ideal for preventive disinfection scenarios, especially in the prevention and control of emerging respiratory infectious diseases.
