Hand Sanitizer Basic Information

(1) The purpose of washing hands is to remove the stains and bacteria on the hands. Therefore, the cleaning power must be considered first, but the cleaning power and degreasing force are proportional. The excellent detergency is accompanied by the strong degreasing effect. Should choose a mild non-irritating surfactant.
(2) Rich and long-lasting foam and easy-to-rinse are important indicators of the quality of hand sanitizer products. Rich, long-lasting and easy-to-rinse foam can bring users an easy experience of washing hands without burden, so focus on formula design Consider foaming and stabilizing properties and ease of washing.
(3) The ability to remove bacteria is the key to real cleanliness of hand washing, and it is the reason that it is mainly used in public places as a hand sanitizer. [1]

History of Hand Sanitizer

Many daily activities of people are completed by two hands, there are many things to touch, and there are many kinds of stains. Therefore, hand washing is the most frequent in people's daily hygiene. Therefore, hand washing products came into being. Due to the constraints of living conditions and the market, people used to wash their hands with soap, soap and washing powder. Although they can achieve a certain cleansing effect, they have irritating effects on the skin. Long-term use will cause some people's skin to be rough, Cleft and peeling. The hand is the second face of the human body, and people, especially women, are more willing to work hard to protect her. As a cleansing and nursing article specially used for hand washing, with the advancement of technology, the application of new surfactants, auxiliaries and mild, natural antiseptics is packaged in a pressure pump bottle, making the hand sanitizer a "moisturizing" special Function; The use mode of "pressure pump to prevent cross infection", "liquid washing, more fashionable" buying point cut into consumer groups, quickly recognized by consumers, becoming a substitute for traditional hand washing products, which has become hand washing and cleaning The development trend of care products. [2]

Product Category

(1) General hand sanitizer: cleaning and decontamination effect.
(2) Hand sanitizer for heavy oil stains: cleaning of industrial oil stains (such as motor oil, gasoline, butter, diesel, etc.) and stubborn stains.
(3) Children's hand sanitizer: For children's hand sanitizer, non-toxic, non-irritating / low-irritating raw materials must be selected, and the amount of pigments and flavors should be minimized. Some green surfactants such as alkyl glycosides, amino acid surfactants, and plant-based emollients are often used in children's hand sanitizers.
(4) Water free hand lotion
Another type of this type of product is the use of guanidine cationic fungicides and auxiliaries, mainly for daily sterilization of the skin on the hands. Spray directly on the hand when using. [3]
(6) Hand Sanitizer for Hospital
There are mainly two types of hand sanitizers often used in hospitals. One is a hand sanitizer that has the effect of removing bacteria, and the other is a hand sanitizer disinfection product used under specific conditions such as before surgery and blood draw. This type of product is basically free of anions. Surfactants are mainly composed of double-chain quaternary ammonium salts, chlorhexidine gluconate, chlorhexidine acetate, chlorhexidine gluconate, chlorhexidine gluconate, benzalkonium chloride, It is composed of ethanol, isopropanol, polyhexamethylene biguanide and adjuvant.
Different hand sanitizers are different in outer packaging. Ordinary hand sanitizers are generally "quasi-brand", while disinfectant hand sanitizers are mostly "elimination".
Hand sanitizers are generally free of phosphorus, aluminum, alkali, sodium alkylbenzene sulfonate and other ingredients. They are mildly decontaminated and easily accepted by the skin [3] .

Hand washing method

Moisten your hands thoroughly with water, take an appropriate amount of hand sanitizer and rub your hands thoroughly.
For more than 30 seconds, in the process, pay attention to rubbing to the fingertips and fingers, and allow the foam to cover all parts of the entire hand. After rubbing, rinse with running water. Finally, pay attention to dry with a clean dry towel or paper towel, it is best not to dry, because the rapid evaporation of water on the surface will cause part of the skin to lose water, causing the skin to dry out and become rough.
Many restaurants, shopping malls, toilets and other public places provide free hand sanitizers in the toilets. It is also convenient to ask questions: Are these free hand sanitizers harmful to the skin? In fact, even small bottles of hand sanitizer purchased at home may Quality problems such as bacterial exceeding standards and poor emulsification effects have occurred. China has promulgated the industry standard for hand sanitizer products as QB2654-2004 "Hand Sanitizer".

The main ingredients of hand sanitizer

(1) Decontamination component [3]
Detergent ingredients are used to provide detergency and rich foam, mainly anionic surfactants and small amounts 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 sulfo Disodium succinate and so on. Soap and sodium lauryl sulfate are the earliest surfactants used in hand sanitizers. Due to their respective deficiencies such as strong degreasing properties, the high pH value of soap and low hard water resistance, calcium soaps have been formed. used.
Non-ionic surfactants are generally less used in hand sanitizers. Small additions can improve detergency and foam stability, such as coco diethanolamide, where the addition of alkyl glycosides can reduce the effect of surfactants. Skin irritation. The addition of a small amount of zwitterions is beneficial to the longevity of foam and foam, betaine and amine oxide.
(2) Nursing ingredients
When washing hands, due to the degreasing effect of surfactants, the skin feels dry after hand washing. Therefore, some fat rich agents and emollients should be added to replenish skin oil to prevent dry and rough skin, such as various natural and synthetic lanolin, glycerin, Propylene glycol, sorbitol, lactate and sodium pyrrolidone carboxylate.
(3) Sensory adjustment components
In order to make consumers prefer and accept hand sanitizers and give special effects and appearance to hand sanitizers, add dyes or pearlescent agents; for convenience, add thickeners to adjust a suitable viscosity; in order to have a kind of Easy and pleasant feeling with the right amount of fragrance.
(4) Natural ingredients
With the increase of people's awareness of safety and environmental protection, they are more advocating for green and natural products. Therefore, adding natural ingredients to the hand sanitizer formula is the choice of many hand sanitizer brands. These natural additives play a role in reducing irritation, moisturizing the skin, and providing a natural aroma and The role of color, such as various plants, Chinese herbs, fruit extracts, aloe, ginkgo, chrysanthemum, ginseng, Tianqi, licorice, peony peel, tea fruit and lemon and so on. [3]

The development trend of hand sanitizer

(1) Concentrated
According to the provisions of QB 2654-2013 "Hand Sanitizer", hand sanitizer is divided into ordinary type and concentrated type according to the content of active substance. Among them: ordinary actives require 7% or more, concentrated actives require 14% or more. Concentrated products have the advantages of less consumption, lower transportation costs, saving packaging materials, and less storage space. It is believed that with the promulgation of standards, more and more concentrated products will be introduced on the market. However, it should be noted that the hand washing liquid is squeezed by the pump head. The mainstream hand washing liquid on the market is squeezed at a rate of 1.2g ~ 1.5g. After concentration, the squeeze amount of the pump head should be controlled at 0.6g ~ 0.9g. Between [4]
(2) Product form and function diversification
The function of hand sanitizers has evolved from a single washing type to skin care, skin beauty, nutrition and special functional types. Only by diversifying the functions of hand sanitizers can it meet the different needs of different consumer groups. For example, foam hand sanitizer is a class of hand washing products developed in recent years. Because of direct foaming, the use of new forms, more convenient and fast use, more and more people love; emollients developed based on dry skin of the elderly Strong hand sanitizer; mild hand sanitizer for pregnant women; portable products for people who travel frequently.
In response to consumers' increasing awareness of cleanliness, Japan has developed a finger disinfectant. This product contains active ingredients such as alcohol, benzalkonium chloride, and gluconic acid acetylene chloride. It can be dried after scrubbing your fingers. Simple disinfection of fingers in water. The advantages of this product have been recognized by Japanese consumers.
(3) Products are more green
China is at the peak of urbanization and urban environmental pollution is becoming increasingly prominent. The dense population, concentrated industry, and large consumption of fossil fuels have deteriorated the air quality of many large cities. In this environment, consumers pay great attention to the harmony of man and nature while focusing on product functions. Therefore, green and safe hand sanitizer products made from a combination of highly safe green surfactants and natural active ingredients containing aloe, sea buckthorn oil, wild chrysanthemum and other flowers have been favored by more and more consumers. .

What are the hazards of using expired hand sanitizer?
Bacteria such as Pseudomonas aeruginosa caused by expired hand sanitizer can cause great harm to the human body.
It is understood that because Pseudomonas aeruginosa is a pathogenic bacteria, it can cause a variety of diseases such as wound infection and pneumonia. It is highly pathogenic to the human body and can cause purulent sepsis; S. aureus is also a pathogen Can cause purulent infections and sepsis. Mr. Li of the National Quality Supervision and Inspection Center of Washing Products reminded consumers to pay attention to the fact that when using hand sanitizers in public places, they must first pay attention to whether the hand sanitizer has odors, pungent odors and other odors. Or use prohibited raw materials, this hand sanitizer is best not to use. Secondly, it is also necessary to observe whether the hand sanitizer has delamination or oil-water separation phenomenon. If there is, it indicates that the manufacturer does not control the emulsification process during the product production process, which will affect the washing effect. It is best not to use it.
Hand sanitizer is not a substitute for soap
Removal of dirt and sterilization are the main purposes of hand washing. The hand sanitizer can only meet its bactericidal effect, because most hand sanitizers contain alcohol. Alcohol cannot effectively remove some dirt, such as dust, dirt, blood stains, etc. that are attached to small skin gaps. With such contamination, hand sanitizer alone is not enough. It can be seen that the premise of using hand sanitizer is to remove these dirt first. Therefore, in this case, you should use soap to wash your hands instead of just using hand sanitizer. In fact, when you go to the hospital, you will find that many doctors wash their hands with soap, not because the price of soap is cheap.
Hand sanitizer can only be used as a reserve for soap. The best way to wash your hands is to wash your hands with soap to remove dirt, and then use hand sanitizer to sterilize and moisturize the skin. When using hand sanitizer, it is not good enough, it is enough to press one drop each time. After repeated rubbing on the hands, rinse with running water for more than 15 seconds, so that the hand sanitizer can be thoroughly cleaned. Although many hand sanitizers contain skin care ingredients, if you wash your hands frequently in dry winters, it will still lead to dry hands. Therefore, you should apply special moisturizing hand cream after washing your hands.
Why use hand sanitizer after washing, the hands will be very wet and not easy to dry
The most important thing is to have the purpose of decontamination and sterilization, although it is some surfactants. The hand sanitizer is directly facing the skin, and it is directly applied to the skin, so the pH has higher requirements and cannot be alkaline. Its washing ingredients are relatively mild. The most important thing is to avoid degreasing. If the hand sanitizer is degreased, a lot of soap can cause the phenomenon of wrinkles on the fingers and belly. In short, degreasing is not good for the skin. Apparently, hand sanitizers are lotions, and they are also easy to rinse if they are applied to the hands. This should not be very good, and the hand sanitizer is designed and easy to use, the concentration has been adjusted before, and the lotion has a large amount of water as a solvent after all, it is easy to rinse clean, due to good skin affinity. In addition, there are some minor differences in additives, such as glycerin in hand sanitizers and the ingredients of aloe. [1]

Hand Sanitizer

1. To buy from regular shopping malls, regular shopping malls have more stable purchasing channels and stricter purchase control systems.
2. Observe whether the packaging is intact, whether the handwriting on the packaging bottle is clear, and whether the pump head is strong. Generally, hand washing liquid is squeezed out of the pump head. If the packaging quality is poor, the liquid will not leak or leak during use, causing inconvenience and waste.
3. Check whether the signs are complete. If there is no factory name, site, etc., pay special attention to whether there is a standard number. Although there is no uniform national standard for hand sanitizers, the country does not allow non-standard production. Therefore, each manufacturer must formulate an enterprise standard and indicate the enterprise standard number on the packaging to ensure product quality.
4. Pay attention to the contents, that is, the hand sanitizer itself. Smell if there is any odor such as odor or pungent smell. If so, it may be past its shelf life or use of prohibited ingredients, it is best not to buy and use. Also observe whether there is delamination or oil-water separation phenomenon, if it shows that the emulsification process is not well controlled in the production process, it will affect the washing effect.
