目的研究一种含过氧化硫酸盐的除菌洗衣粉杀菌效果及其他性能。方法采用悬液定量杀菌试验和理化分析方法,对该除菌洗衣粉的相关性能进行了观察。结果该除菌洗衣粉中过氧化硫酸盐含量折合过氧化氢约为质量分数0.46%,将其密封储存于40℃恒温箱3个月有效成分含量下降4.35%。用含10g/L该除菌洗衣粉溶液作用20min,对悬液内大肠杆菌的平均杀灭率为99.06%,对金黄色葡萄球菌的平均杀灭率为100%。结论以含过氧化硫酸盐为杀菌成分的除菌洗衣粉具有良好的抗菌效果,性能稳定。
Objective To study the bactericidal effect and other properties of a bactericidal detergent containing peroxosulphate. Methods Suspension quantitative germicidal test and physical and chemical analysis methods were used to observe the relative performance of the sterilized washing powder. Results The content of peroxosulphate in the sterilized washing powder was about 0.46% of hydrogen peroxide. The content of active ingredient in the sterilized washing powder was reduced by 4.35% after stored for 3 months at 40 ℃. With 10g / L of the sterilized detergent solution for 20min, the average killing rate of E. coli in the suspension was 99.06% and the average killing rate of Staphylococcus aureus was 100%. Conclusion The bactericidal detergent containing peroxosulphate has a good antibacterial effect and stable performance.
