Abstract:
Objective To study the bacteriostasis effect of one of the isothiazolinone derivatives KF-88 and observe its bacteriostasis efficacy in detergent.
Methods To use nutrition broth dilution method to determine its minimal inhibitory concentration (MIC) to straphylococcus aureus, Escherichia coli, Candida albicans and Aspergillus niger, and complete the simulated on-the-spot tests.
Results The MIC of KF-88 to straphylococcus aureus and Candida albicans was 0.0016‰; the MIC to Escherichia coli and aspergillus niger was 0.03‰; KF-88 could restrain straphylococcus aureus to propagate in detergent when its concentration in detergent was 1‰.
Conclusion The isothiazolinone derivatives had very strong bacteriostasis efficacy for bacteria, mildew and yeast, they have valuable application prospect in detergent industry and other industry field.
