What is the washing principle of foam hand sanitizer?

If you are careful, you will find that ordinary hand sanitizer is particularly easy to solidify in cold weather. In normal weather, extrusion needs a lot of water to wash. Only compared with soap, there will be no cross infection. The foam hand sanitizer, through the magical pump head, directly produces rich foam, which is more convenient for cleaning hands, and the water consumption is half that of ordinary hand sanitizer. Compared with ordinary hand sanitizer, foam hand sanitizer has an innovative breakthrough in function and concept. Simply put, the foam is rich, and the foam is directly pressed out, which can be washed-free or some need to be washed. This kind of foam hand sanitizer is water-saving and relatively clean and easy to rinse. Its principle is that there is a special device at the bottle mouth to fully mix air and foaming agent. Have you ever seen a foam gun for fire fighting? There must be experiments in middle schools. The drooping paper floats to the place where the gas flows, because the fluid has a decompression effect. In the middle of the foam gun is an ordinary gun head, and a sleeve with many holes on the side is added outside. When the foaming agent is ejected from the middle of the sleeve, a large amount of air is sucked in from the side and mixed with it to produce foam. Ordinary hand sanitizer uses hand sanitizer to squeeze out bubbles, while Verus foam hand sanitizer can turn hand sanitizer into foam through the pump head. Extrusion is foam, which saves time, but its cleaning power is still good. And the dosage is half that of ordinary hand sanitizer. Finally, we should pay attention to the contents, that is, the hand sanitizer itself, and smell whether there is a 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.
