Q: What are the ingredients of hand sanitizer?

Most people only know that hand sanitizer is used to wash hands and keep hands clean and healthy, but do you know what the ingredients of hand sanitizer are? Below, follow the editor to see it together! ​1. Surfactant Surfactant is the main ingredient in the formula of hand sanitizer. Its basic function is to remove the grease and dirt on the hands and generate a certain amount of foam. 2. Emollient and moisturizing agent Emollient and moisturizing agent is also an essential ingredient in hand sanitizer. Glycerin is widely used. It can leave a protective film after the moisture on the skin surface evaporates, preventing or slowing the loss of moisture inside the skin. Keep the skin moisturizing. 3. Thickener Thickener When using hand sanitizer, if the viscosity is too small and it is not easy to stay in the hand, the decontamination ability will be affected. The most commonly used thickeners are inorganic salts, such as NaCl, which are inexpensive, have good thickening effects and are easy to use. 4. Slip-reducing agent In order to reduce the slippery phenomenon of the hand sanitizer during the washing process and increase the clean feeling of the skin, a certain slip-reducing agent can be added to the formula. C18-20 anionic surfactants can locally form a large surface tension in the hand sanitizer and reduce the slippery feeling during the washing process. Among them, mild ones can be selected as slip reducing agents. 5. In order to prevent and inhibit the growth of bacteria and ensure that the product has a certain storage period, a certain amount of bactericidal preservatives must be added to the hand sanitizer. Preservatives that are non-toxic, non-irritating to the skin, light in color and cheap should be selected. Commonly used are sodium benzoate. You can choose a fruity, floral or light fragrance to adjust the aroma.
