Ordinary hand sanitizer is mainly used for cleaning and decontamination. The number of hygiene license on the package is generally "hygiene license".

Bacteriostatic hand sanitizer has more bacteriostatic or bactericidal ingredients than ordinary hand sanitizer, and the health license number on the package is generally "weixiaozheng". Bacteriostatic hand sanitizer can inhibit common bacteria, such as enteropathogenic bacteria and pyogenic cocci, on product publicity and packaging. Some will also indicate that "under laboratory conditions, it can inhibit 99.9% of Staphylococcus aureus, the results are for reference only". So in real life, how much bacteriostatic effect does bacteriostatic hand sanitizer have on the microorganisms in our hands?

The results show that no matter how to wash hands, it can significantly reduce the number of hand microorganisms. But at the same time, we also found that the antibacterial effect of antibacterial hand sanitizer is not different from that of clean water hand sanitizer, that is, antibacterial hand sanitizer has no antibacterial effect (within one hour).

Although antibacterial hand sanitizer is indicated to contain antibacterial ingredients, it can only inhibit certain types of microorganisms, while the microorganisms in life are various and have different activities. The experiment shows that the antibacterial hand sanitizer selected this time has not good antibacterial effect in practice. Therefore, it seems that the main function of antibacterial hand sanitizer is to clean and remove grease.
