It seems that paying attention to washing hands is not only "washing hands before and after meals", but also washing hands after going to public places; We should not only wash our hands often in emergencies, but also insist on "washing our hands" as a good hygiene habit in our daily life.
I believe that most people choose hand sanitizer because it is easy to use and can sterilize and moisturize. But hand sanitizer can't replace soap.
Removing dirt, sterilization and disinfection are the main purposes of hand washing. Hand sanitizer can only meet its sterilization function, because most hand sanitizers contain alcohol, and alcohol can not effectively remove some dirt attached to tiny gaps in the skin, such as dust, dirt, blood stains and so on. So once your hands are contaminated with this dirt, it is not enough to use hand sanitizer only. 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, not just hand sanitizer.
Of course, not all hand sanitizers contain the same ingredients. If the alcohol content in hand sanitizer is lower than 60%, the sterilization effect will be greatly reduced. If you wash your hands with this hand sanitizer, it's actually useless. When buying hand sanitizer, pay attention to the content of effective ingredients marked on the product label. Some hand sanitizers will indicate the contents of ethanol, p-aminobenzoic acid and isopropanol, not alcohol. What needs to be confirmed is that no matter which form is marked, its content should be between 60% and 95%. If the content is lower than 60%, viruses and bacteria cannot be effectively killed. However, the higher the alcohol content, the better. If the alcohol content is higher than 95% or pure alcohol, the sterilization effect will be inhibited.
Hand sanitizer can only be used as a backup force for 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. When using hand sanitizer, it is not always better. One drop at a time is enough. After rubbing hands repeatedly, rinse with running 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 often in dry winter, your hands will still be dry, so you should apply special moisturizing hand cream after washing your hands.
It is the best choice to keep the towel for wiping hands clean and dry, boil and disinfect it regularly, or wipe hands directly with paper towels.
Matters needing attention in purchasing hand sanitizer
1. If you want to buy from a regular shopping mall, the regular shopping mall has relatively stable purchase channels and strict purchase control system.
2. Observe whether the package is intact, whether the handwriting on the packaging bottle is clear and whether the pump head is firm. Generally, hand sanitizer is discharged by squeezing the pump head. If the packaging quality is poor, it will not be discharged or leaked during use, causing inconvenience and waste.
3. See whether the signs are complete, such as the name and address of the factory, and pay special attention to whether there is a standard number. Although there is no unified national standard for hand sanitizer at present, the state does not allow non-standard production, so all production enterprises should formulate enterprise standards and indicate the enterprise standard number on the packaging to ensure product quality.
4. Pay attention to the contents, that is, the hand sanitizer itself, and smell whether there is bad smell, pungent smell and other smells. If so, it may have passed the shelf life or used prohibited raw materials. It is best not to buy and use them. Also observe whether there is stratification or oil-water separation, if there is, it means that the emulsification process is not well controlled in the production process, which will affect the washing effect.
