【摘要】：目的评估速干型手消毒剂开启30 d后乙醇有效浓度及杀菌能力。方法使用乙醇浓度计对开启后3、5、7个月的A品牌泡沫型、B品牌凝胶型和液体型速干手消毒剂的乙醇浓度进行测试,采用悬液定量杀菌试验法检测手消毒剂的杀菌性能。结果两种品牌的速干型手消毒液开启3个月后的乙醇浓度均在出厂标注的有效浓度范围内。以开启3个月的A品牌泡沫型、B品牌凝胶型手消毒剂原液作用1 min,对悬液内的铜绿假单胞菌、金黄色葡萄球菌和白色念珠菌及黑曲霉菌的杀灭对数值均5;B品牌液体型对金黄色葡萄球菌和黑曲霉菌的杀灭对数值均5。A品牌泡沫型开启5个月,对金黄色葡萄球菌、白色念珠菌和大肠杆菌的杀灭对数值均5;B品牌凝胶型分别开启5、7个月对黑曲霉和大肠杆菌作用1 min的杀灭效果均符合要求。结论 A、B品牌的速干型手消毒液开启3个月后仍具备合格的乙醇含量和杀菌能力。
[Abstract]:Objective to evaluate the effective concentration of ethanol and bactericidal ability of quick dry hand disinfectant for 30 days. Methods Alcohol concentration of A brand foam gel type and liquid type quick dry hand disinfectant was measured by alcohol concentration meter. Suspension quantitative germicidal test method was used to test the bactericidal performance of hand disinfectant. Results the ethanol concentration of the two brands of hand disinfectant was within the range of effective concentration after 3 months of opening. The suspension of Pseudomonas aeruginosa (Pseudomonas aeruginosa) was treated with the raw solution of A brand foam and B brand gel hand disinfectant for 1 min after opening for 3 months. The logarithmic values of killing of Staphylococcus aureus, Candida albicans and Aspergillus Niger were all 5%. The logarithmic values of 5% B liquid type on Staphylococcus aureus and Aspergillus Niger were 5.A brand foam type for 5 months, and 5 months for Staphylococcus aureus. The killing logarithm values of Candida albicans and Escherichia coli were 5% and 5%, respectively, and the efficacy of killing 1 min of Aspergillus Niger and Escherichia coli for 7 months were up to the request. Conclusion the quick dry hand disinfectant of AZB brand still has qualified alcohol content and bactericidal ability after 3 months of opening.
