How to Choose Hand Sanitizer?
- 20 Feb 2020 23 Jan 2021
Generally, when we buy hand sanitizer, we will see advertisements promoting its antibacterial, antibacterial, or antibacterial effects. Sterilization means eliminating and killing bacteria. It is the most basic and important function of hand sanitizer. Antibacterial and antibacterial are similar, generally referring to the inhibition of bacterial reproduction within a period of time after washing hands.
In the past, hand sanitizers generally achieved the so-called antibacterial and antibacterial effects by adding triclosan, triclocarban, p-chloro-m-xylenol, and other ingredients. But in fact, p-chloro-m-xylenol has low toxicity, low concentration in hand sanitizer, and it is difficult to stay on the hands after washing, and cannot be antibacterial for a long time; the antibacterial effect of triclosan and triclocarban is also It is not significant, and when it enters the environment, it will increase bacterial resistance.
And living in an environment that is too clean and free of bacteria for a long time is not conducive to the balance of our immune system, especially for growing children. Seeing the results that do more harm than good, the US Food and Drug Administration has intentionally or has banned the use of these ingredients in hand sanitizers.
Although most of the hand sanitizers no longer add these three ingredients, many manufacturers still emphasize the "bacteriostatic" effect during publicity. When you buy, you only need to pay attention to sterilization and don't take antibacterial and antibacterial effects as the purchase criteria.
Hand sanitizer, soap
1. Buy ordinary soap and hand sanitizer.
Wash your hands with running water + ordinary hand sanitizer/soap, you can achieve good sterilization and disease prevention effects.
2. Choose children's hand sanitizer and avoid isothiazolinone preservatives and fragrances.
Methylisothiazolinone (MIT), methylchloroisothiazolinone (CMIT), and benzisothiazolinone (BIT) are all isothiazolinone preservatives. They all have the potential to cause sensitization, so the use of such ingredients in skincare products that stay on the skin has been banned. Because children's hands are more delicate, it is best to avoid this ingredient in hand sanitizers for children.
Many children like to eat their hands. If too much fragrance is added to the hand sanitizer, it will not be beneficial to the child's body if the hand sanitizer is left, so it is better to choose a fragrance-free hand sanitizer.
Disposable hand sanitizer
1. The alcohol concentration must reach 60%.
Most disposable hand sanitizers use alcohol to kill bacteria on the hands and prevent diseases. In order to achieve a better sterilization effect, everyone should choose a hand sanitizer with an alcohol content of more than 60%.
2. You can choose an alcohol-free hand sanitizer for children.
Alcohol-free hand sanitizers have strong degreasing power and high permeability, and when they evaporate, they take away the moisture from the hands, which will harm the delicate skin of children. So you might as well choose an alcohol-free hand sanitizer that is disinfected with benzalkonium chloride.
