Is foam hand sanitizer better or liquid hand sanitizer? What raw materials are hand sanitizer made of?

Hand sanitizer is a very common item on the market. Many people have hand sanitizer at home. There are many types of hand sanitizers, including foaming ones. So is foaming hand sanitizer better or liquid one? What are hand sanitizers made of?

Is hand sanitizer better, foam or liquid?

The foamy ones are better. Foaming hand soap has innovative breakthroughs in function and concept compared to ordinary hand soap. Foam is produced directly by pressing, eliminating the need to rub with water to produce foam. This type of foam hand soap saves water and is cleaner and easier to rinse. Each use is 1/2 the amount of ordinary hand sanitizer. It foams directly and is not easy to fall off, so that the effective ingredients in the foam can be fully utilized, greatly improving the cleaning, sterilization and moisturizing effects. The foam is rich and the effective ingredients can be fully utilized, which greatly improves the cleaning, sterilization and moisturizing effects. Some specific ingredients can have a disinfecting and sterilizing effect. For example, Escherichia coli, Staphylococcus aureus, Streptococcus, etc. Foam hand sanitizer is more convenient to use. It is very different from ordinary hand sanitizers because it is mainly foam. Some of them are wash-free and have sterilization effects.

What are hand sanitizers made of?

Non-ionic surfactants are generally rarely used in hand sanitizers. Adding a small amount can enhance the decontamination effect and improve the stability of the foam, such as coconut acid diethanolamide. The addition of alkyl glucoside can reduce the irritation of surfactants to the skin. The addition of a small amount of zwitterions is beneficial to foaming and foam durability, betaine and amine oxide. When washing hands, the skin feels dry due to the degreasing effect of surfactants. Therefore, some refatting agents and emollients should be added to replenish skin oil and prevent the skin from drying and roughening, such as various natural and synthetic lanolin, glycerin, propylene glycol, sorbitol, lactate and sodium pyrrolidonecarboxylate. In order to make consumers like and accept hand sanitizer more, special effects and appearance are given to hand sanitizers, such as adding dyes or pearlescent agents; thickeners are added to adjust a suitable viscosity for easy use; and appropriate amounts of flavors are added to create a relaxed and pleasant feeling during the hand washing process. As people's awareness of safety and environmental protection increases, they prefer green and natural products. Therefore, adding natural raw materials to the formula of hand sanitizer is the choice of many hand sanitizer brands. These natural additives reduce irritation, moisturize the skin and provide natural fragrance and color, such as various plants, Chinese herbs, fruit extracts, aloe vera, ginkgo, chrysanthemum, ginseng, Panax notoginseng, licorice, peony bark, tea fruit and lemon, etc.

Types of hand sanitizer

There are two main types of hand sanitizers on sale, one that does not have antibacterial effect and the other that does. Hand sanitizers with antibacterial effects fall into the category of disinfection products and can only be produced after a production hygiene license is issued by the provincial or municipal health bureau, but there is no need to apply for a hygiene license or hygiene permit from the Ministry of Health. Hand sanitizer is a disinfection product and can only be produced and sold after obtaining a market hygiene license issued by the province or city and a "Weixiao Zi" license issued by the Ministry of Health. It is not easy to obtain the "Health and Disinfection Label". The prerequisite is that the product must undergo strict safety and disinfection effect inspections. If the product is antibacterial, the bactericidal rate against Escherichia coli (8099 or ATCC25922) and Staphylococcus aureus (ATCC6538) must be ≥90%. If the product is marked as having an effect on fungi, the bactericidal rate of Candida albicans (ATCC 10231) must also be included. If the product is antibacterial, the antibacterial rate against Staphylococcus aureus (ATCC6538) and Escherichia coli (8099 or ATCC25922) must be ≥50%.

Is hand sanitizer alkaline?

Hand sanitizer is alkaline. Shower gel, hand sanitizer, and soap are all alkaline because the sweat secreted by the human body is acidic. In addition, the inorganic salts precipitated with sweat and the oil secreted by the skin surface make the dirt on the skin acidic, so cleaning products are made to be alkaline. The hand sanitizer does not contain ingredients such as phosphorus, aluminum, alkali, and sodium alkylbenzene sulfonate. It uses the principle of mild decontamination and is easily accepted by the skin. Hand sanitizers are alkaline and can irritate children's skin. In addition, people with skin allergies should not use hand sanitizer to wash their hands. There are two types of hand sanitizers: ordinary hand sanitizer and disinfectant products. The former plays a role in cleaning and removing dirt, while the latter contains effective ingredients that have antibacterial, antibacterial or bactericidal effects.
