How to choose hand sanitizer1

Generally, when we buy hand sanitizer, we see ads advertising its germicidal, antibacterial or antibacterial properties. Sterilization is the most basic and important role of hand sanitizer. Antibacterial is similar to antibacterial, which generally refers to inhibiting the reproduction of bacteria for a period of time after washing hands. In the past, hand sanitizers usually achieved the so-called antibacterial and bacteriostatic effect by adding ingredients such as triclosan, triclocarban, and p-chlorometaxylenol. But in fact, the toxicity of p-chloro-meta-xylenol is low, the concentration of hand sanitizer is low, it is difficult to stay on the hands after washing, and it cannot be antibacterial for a long time; the antibacterial effect of triclosan and triclocarban is not significant, and it will increase the bacteria after entering the environment. drug resistance. Living in an environment that is too clean and bacteria-free for a long time is also not good for the balance of our immune system, especially for growing children. Seeing that they could do more harm than good, the FDA has intentionally or banned the use of these ingredients in hand sanitizers. While most hand sanitizers no longer contain these three ingredients, many manufacturers still emphasize bacteriostatic effects. Everyone only pays attention to sterilization when purchasing, and do not regard antibacterial and bacteriostatic as the purchasing criteria. NO.1 Hand sanitizer, soap. 1. Buy regular soap and hand sanitizer. Washing hands with running water + ordinary hand sanitizer/soap can achieve good sterilization and disease prevention effects. 2. Choose children's hand sanitizers and avoid isothiazolinone preservatives and fragrances. Methylisothiazolinone (MIT), methylchloroisothiazolinone (CMIT), and benzisothiazolinone (BIT) are all preservatives for isothiazolinone. They all have the potential to be allergic, so this ingredient is a no-no in skincare products that stay on the skin. Since children's hands are relatively delicate, it is best to avoid this ingredient in hand sanitizers for children to be on the safe side. Many children like to eat their hands. If too much fragrance is added to the hand sanitizer, it will not be good for the child's body if it is left on the hands, so it is better to choose an unscented hand sanitizer. NO.2 Disposable hand sanitizer 1. The alcohol concentration should reach 60%. Most hand sanitizers use alcohol to kill germs on your hands and prevent disease. In order to achieve a better sterilization effect, we should choose a hand sanitizer with an alcohol content of more than 60%. Second, choose an alcohol-free hand sanitizer for children. The alcohol-based hand sanitizer itself has strong degreasing ability and high permeability. When it evaporates, it will damage the delicate skin of children by taking away the moisture from the hands. Therefore, you may wish to choose an alcohol-free hand sanitizer that is disinfected with benzalkonium chloride. 1. Disposable hand sanitizer is only for emergencies, and water + hand sanitizer/soap should be used to wash hands if conditions permit. When there is dirt and other dirt on your hands, you cannot use hand sanitizer to remove them. And whether it's alcohol or non-alcohol hand sanitizers, they have limited germicidal ability, and the possibility of adding chemical germicides or harming the skin is limited. It is best to wash your hands with water, hand sanitizer, and soap. 2. It is best not to put non-foaming hand sanitizer in a foaming bottle. Dispensing non-foaming hand sanitizers into foaming bottles without adding water can cause the container to clog, and adding water can dilute the concentration of preservatives in the hand sanitizer, causing it to spoil. Therefore, if you want to save foam time, it is better to buy a hand sanitizer with direct foam. 3. Wash your hands with running water for enough time, hand sanitizer and soap can achieve the best disease prevention effect. In fact, how you wash your hands is more critical to preventing disease than what you use to wash your hands. The correct way to wash your hands should be: Rinse hands with running water, apply hand sanitizer or soap, rub palms, backs of hands, between fingers, fingers, wrists and arms for at least 20 seconds, then rinse with clean water.
