Hand sanitizer is a kind of skin care cleanser used to clean the hands. It removes the dirt and attached bacteria on the hands through the action of mechanical friction and surfactants, with water flow or without water. (1) Decontamination ingredients Decontamination ingredients are to provide decontamination and rich foam, mainly anionic surfactants and a small amount of nonionic and zwitterionic surfactants. Anionic surfactants are soap, sodium lauryl sulfate, Q-olefin sulfonate, fatty alcohol polyoxyethylene ether sulfate, Q-sulfo fatty acid ester, lauroyl sarcosinate and monooleic acid amide sulfonate Disodium succinate, etc. Soap and sodium lauryl sulfate are the earliest surfactants used in hand sanitizers. Due to their respective disadvantages such as strong degreasing, high pH value of soap and low resistance to hard water, calcium soaps have been less frequently used. used. Non-ionic surfactants are generally less used in hand sanitizers, and a small amount of them can improve detergency and improve foam stability, such as coco acid diethanolamide, where the addition of alkyl glycosides can reduce the effect of surfactants. For skin irritation, a small amount of zwitterions is added to facilitate foaming and long-lasting foam, betaine and amine oxide. (2) When washing hands with care ingredients, due to the degreasing effect of surfactants, the skin feels dry after hand washing, so some fat-enriching agents and emollients should be added to supplement skin oils to prevent dry and rough skin, such as various natural and synthetic products. Lanolin, Glycerin, Propylene Glycol, Sorbitol, Lactate and Sodium Pyrrolidone Carboxylate etc. (3) The antibacterial components are always in contact with the outside world, and the hands will be contaminated with all kinds of bacteria and even fungi. Therefore, the bactericidal components must be broad-spectrum, such as 3,4,4'-trichloro- 2'-hydroxyphenyl ether, chloroxylenol, Chinese herbal medicine extracts, etc., in order to improve the bactericidal efficiency of the bactericide, it is also necessary to add an adjuvant to increase the penetration force, so that the bactericidal component can penetrate into the bacterial wall and sterilize quickly. Enhance sterilization efficiency. (4) Sensory adjustment ingredients In order to make consumers prefer and accept hand sanitizer, give special effect and appearance to hand sanitizer, add dye or pearlescent agent; add thickener to adjust a suitable viscosity for convenience; Add the right amount of fragrance for a lighthearted feeling during hand washing. (5) Natural ingredients With the improvement of people's awareness of safety and environmental protection, green natural products are more advocated. Therefore, adding natural raw materials to the formula of hand sanitizer is the choice of many hand sanitizer brands. These natural additives play a role in reducing irritation, moisturizing the skin, Antibacterial, antibacterial, and providing natural aroma and color, such as various plants, Chinese herbal medicines, fruit extracts, aloe vera, ginkgo, chrysanthemum, ginseng, Tianqi, licorice, peony, tea fruit, sterilization and lemon, etc. .
