According to South Korea's MBC TV station, hand sanitizer placed in public places is not safe and may be "full of bacteria". The research team from Chungbuk University of Health Sciences in Korea tested the hand sanitizer in public toilets in Cheongju City, and found pathogenic bacteria in 92% of the hand sanitizer. Experts say that these hand sanitizers are constantly poured into hand washing devices in the later stage, and the use of hand sanitizers may have the opposite effect and spread bacteria.

In addition, if the hand sanitizer in public places is not replaced in time, the disinfection and sterilization effect of expired hand sanitizer will be reduced. Moreover, because hand sanitizer itself contains a lot of nutrients, leaving it for too long will produce foam and oil-water separation, which will promote the growth and reproduction of bacteria. Washing hands with such hand sanitizer will not achieve the purpose of cleaning hands, but will leave some bacteria on hands.

Reduce the risks associated with hand sanitizers

Compared with washing hand sanitizer, the pollution risk of alcohol-containing hand sanitizer is relatively small. Even so, the use of contaminated alcoholic hand sanitizer may still lead to microbial transmission and bacteremia. The pollution incident of alcohol-containing hand sanitizer may be due to the unclean alcohol itself or the unclean water used for dilution. Therefore, alcohol disinfectants should not be made at home.

The US Centers for Disease Control and Prevention explicitly advises against refilling hand sanitizers, and many hand sanitizer manufacturers also advise against doing so. Commercial hand sanitizers (both washable and disposable) are usually completely installed. If it is replaced correctly according to the manufacturer's suggestion, there is generally no need to worry about the risk of infection. In addition, solid soap is not recommended. Many families use solid soap to wash their hands, but the surface of solid soap may become a breeding ground for pathogenic microorganisms.

When washing your hands, rub them for at least 20 seconds at a time, and then rinse them with water. Dry your hands with a paper towel or hand dryer after washing your hands, because wet hands are more likely to spread microorganisms such as bacteria. As for hand sanitizer, try to use automatic dispensing hand sanitizer. If you are in a public place, don't use a filled hand sanitizer. If you need to replace the equipment, try to choose sealed hand sanitizer. Whether it is a hand-free disinfectant or a hand sanitizer, don't make or prepare your own hand sanitizer.
