Didecyl dimethyl ammonium chloride is a double-chain quaternary ammonium compound functioning as a medium-level, broad-spectrum disinfectant with potent bactericidal, virucidal, and fungicidal efficacy. It is water-soluble, residue-free, and exceptionally stable in storage. Characterized by a mild, non-toxic, and non-irritating profile, it is widely applicable and safe even for women and infants. Additionally, it can react with specific anions, such as hydroxyl ions, to form corresponding quaternary salts.

Product Application of Didecyl Dimethyl Ammonium Chloride (CAS# 7173-51-5)
Didecyl dimethyl ammonium chloride acts as a potent bactericide targeting Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Legionella pneumophila, Stachybotrys, and various enveloped or non-enveloped viruses. Outperforming single-chain quaternary ammonium salts in efficacy and adaptability, it reliably eliminates bacterial propagules, fungi, and lipophilic viruses. Featuring exceptional water solubility and surface tension-reduction, it is well-suited for preventive disinfection, notably in managing and preventing emerging respiratory infectious diseases.
