Objective To Study the disinfection properties of a long-double-chain quaternary ammonium salt composed with didecyl dimethyl ammonium chloride. Methods Physicochemical examination, disinfectant properties related examination were used to carry out in laboratory to study the properties of the disinfectant. Results The killing logarithms of Escherichia coli , Staphylococcus aureus and Pseudomonas aeruginosa in suspension exposed to the water solution containing the disinfectant 460 mg/L for 0.5 min attained higher than 5.0.The killing logarithm of Candida albicans in suspension exposed to the water solution containing the disinfectant 460 mg/L for 1 rain attained higher than 4.0. The average killing logarithms of natural bacteria on surface was 〉1.0 by the disinfection solution containing 460 mg/L for 5 minutes. Immersion in the disinfection solution containing 460 mg/L for 72 h caused essentially no corrosion of stainless steel and copper coupon, and light corrosion of aluminum coupon and carbon steel. Conclusion The disinfectant was stable, low corrosion and has good efficacy in killing vegetative forms of bacteria and yeast.
