Most hand sanitizers for children contain benzalkonium chloride at a concentration of 0.1%. Hand sanitizers with benzalkonium chloride as the main ingredient are safer for children, but they cannot be said to be absolutely safe. Benzalkonium chloride is also not to be taken orally. After children use it, it will remain on the hands. If it is just licked, it is unlikely to have a negative impact on health. However, if it is swallowed in large quantities, there is still a risk of poisoning.
Benzalkonium chloride is a disinfectant and antiseptic. Commonly used in many medicinal products such as ear, eye, and nasal drops or sprays. Benzalkonium chloride is also a surgical drug, which can be used for skin disinfection before surgery, as well as mucosal and wound disinfection. High concentrations of benzalkonium chloride are irritating to human skin and eyes:
0.1% is the maximum concentration of benzalkonium chloride that will not irritate intact skin;
If a solution with a concentration of more than 0.03% gets into the eyes, immediately rinse with water repeatedly;
Solutions with a concentration greater than 0.02% cannot be used for most mucosal membranes in the human body.
Therefore, it is clear what to pay attention to when using non-alcoholic hand sanitizer for children: be careful not to get in the eyes, not to touch the wound, and of course to avoid the child squeezed into the mouth to eat. For children, occasional use is ok, but regular use is not recommended. It is not recommended to be too lazy to wash your hands, just rub it with hand sanitizer.
