Objectives To gain the knowledge on antibacterial property of disposable sanitary products and to provide scientific basis for assessing the antibacterial properties of these products.
Methods Refer to the Hygienic Standard for Disposable Sanitary Products, and the Test Method for Determining the Resistance of Paint Film to Mold and other standard method to investigate the antibacterial ability of these products.
Results The highest antibacterial effect in 13 sanitary pad samples on Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) in four action time was 100%, and the lowest inhibition rate was higher than 50%. The inhibition rate on Candida albicans (C. albicans) was tested only in one sanitary pad sample, and it was lower than 10%. The highest inhibition rate of 39 liquid material antibacterial agent samples to S. aureus was 100% and the lowest inhibition rate was higher than 90%. The highest inhibition rate to E. coli was 100% and the lowest inhibition rate was lower than 10%. The highest inhibit rate on C. albicans was 100% and the lowest rate was higher than 50%. The highest and the lowest inhibition rate of 20 cigarette filter paper samples at different reaction time on E. coli were both over 90%. The highest inhibition rate of 23 interior decoration material samples and 18 ventilation, and heat-dissipating samples on S. aureus and E. coli was 100% and the lowest inhibition rate was 0%. The highest inhibition rate of 6 liquid materials samples on S. aureus and E. coli was 100% and the lowest value was 99.9%. A total of 41 mildew-resistance samples were tested, 25 mildew-resistance samples were level-0 and 11 mildew-resistance samples were level-1.
Conclusions The antibacterial effect on different bacterial strains could reflect the antibacterial properties of products, which could be used for guiding the assessment of antibacterial ability of products.
