Hand washing is related to health. How to choose hand sanitizer

Hand washing is not a trivial matter. It is related to our health and plays an extremely important role in preventing diseases. According to the health and epidemic prevention department, the “pollution” of hands can not be underestimated. Red eye disease, skin disease, hepatitis A and bacterial dysentery are generally transmitted through hand contact. The above bacteria and viruses are most easily transmitted in some public places and frequently used articles, which are high incidence areas of cross infection of infectious diseases. If we have to touch these things every day and do not pay attention to hand hygiene, the probability of being infected with diseases will be very high.

It seems that to pay attention to hand washing is not only to “wash hands before meals and after defecation”, but also to wash hands in public places; It is not only necessary to wash hands frequently in extraordinary times, but also to persist in “washing hands” as a good hygiene habit in daily life.

I believe most people choose hand sanitizer because it is convenient to use, can kill bacteria, and has the effect of moisturizing the skin. But hand sanitizer can’t replace soap.

Removing dirt, sterilizing and disinfecting is the main purpose of hand washing, but hand sanitizers can only meet their bactericidal function, because most hand sanitizers contain alcohol, which can not effectively remove some dirt, such as dust, mud, blood stains, etc., attached to the small gaps of the skin. Therefore, once the hands are contaminated with such dirt, it is not enough to only use hand sanitizers. It can be seen that the premise of using hand sanitizer is to remove these dirt first. Therefore, in this case, you should wash your hands with soap instead of using hand sanitizer.

Of course, not all hand sanitizers contain the same ingredients. If the alcohol content of hand sanitizers is less than 60%, the bactericidal effect will be greatly reduced. If you wash your hands with this kind of hand sanitizer, it will not work. When buying hand sanitizers, pay attention to check the content of active ingredients marked on the product label. Some hand sanitizers will be marked with the content of ethanol, p-aminobenzoic acid and isopropanol instead of alcohol. What needs to be confirmed is that no matter which form is marked, the content should be between 60% and 95%. If the content is less than 60%, it cannot effectively kill viruses and bacteria. However, the higher the alcohol content, the better. If the alcohol content is higher than 95% or pure alcohol, the bactericidal effect will be suppressed.

Hand sanitizer can only be used as the reserve force of soap. The best way to wash your hands is to wash your hands with soap to remove dirt, and then use hand sanitizer to sterilize and moisturize your skin. When using hand sanitizer, the more the better. It is enough to press one drop each time. After repeatedly scrubbing your hands, rinse them with flowing water for more than 15 seconds, so that the hand sanitizer can be thoroughly cleaned. Although many hand sanitizers contain skin care ingredients, if you wash your hands frequently in dry winter, it will still lead to dry skin on your hands. Therefore, you should apply a special moisturizing hand cream after washing your hands.

The towel used for wiping hands should be kept clean and dry. It is the best choice to boil and disinfect regularly, or to wipe hands directly with toilet paper.

precautions for purchasing hand sanitizer

1. Purchase from regular stores. Regular stores have relatively stable purchasing channels and strict purchasing control system.

2. Observe whether the package is intact, whether the writing on the packaging bottle is clear, and whether the pump head is solid. Generally, hand sanitizer is discharged by squeezing the pump head. If the packaging quality is poor, it will not discharge or leak during use, causing inconvenience and waste.

3. Check whether the signs are complete. If there is a factory name and address, pay special attention to whether there is a standard number. Although there is no unified national standard for hand sanitizer at present, the country does not allow non-standard production. Therefore, all manufacturers should formulate enterprise standards and indicate the enterprise standard number on the package to ensure product quality.

4. Pay attention to the contents, that is, the hand sanitizer itself, and smell whether there is odor, pungent and other peculiar smell. If there is, it may be that the shelf life has expired or prohibited raw materials have been used. It is better not to buy and use them. Also observe whether there is layering or oil-water separation. If there is, it indicates that the emulsification process is not well controlled in the production process, which will affect the washing effect.
