Validation of method for microbial limit test of fast vertical liquid hand disinfect-ant gel / 药学实践杂志

ABSTRACT

Objective To establish a method for microbial limit test of fast vertical liquid hand disinfectant gel .Methods The membrane filtration method, in accordance with the Chinese Pharmacopoeia 2010 Edition (part two) relevant requirements of microbial limit test method for validation of microbial limit test for fast vertical liquid hand disinfectant gel .Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Candida a lbicans, Aspergillus niger were taken as test bacteria , Pseudomonas aeruginosa and Staphylococcus aureus were taken as control bacteria .Verification test was carried out in parallel test for 3 independent , recoveries and every trail rate were calculat-ed.Results In bacteria, molds and yeasts count method validation test , recovery test strain rate , the control bacteria test results met the requirements.Conclusion The membrane filtration method was feasible and effective , which could be used for microbial limit test of fast vertical liquid hand disinfectant gel .
