How to buy hand sanitizer?
Hand sanitizers on the market can be divided into three broad categories of efficacy
The first type is popular hand sanitizer, that is, “liquid soap”, which is mainly based on cleaning agents, and the use of soap is similar to that of cleaning and decontamination.
The second category is antibacterial hand sanitizer, which belongs to disinfection products, which is to add some antibacterial or bactericidal status on the basis of popular hand sanitizer, which can kill the bacteria that cannot be removed by popular hand washing and the skin folds, and ensure the hand washing effect.
The third category is washable hand sanitizers, which are mainly disinfectants such as alcohol and skin care, and also belong to disinfection products.
Choose hand sanitizer need to pay attention to two points:
1, pay attention to the content, that is, hand sanitizer itself, smell whether there is odor, pungent odor. If there may be a warranty period or the use of prohibited materials, it is best not to buy and use.
2. Investigate whether there are stratification or oil-water dispersion signs. If there are, note that the emulsification process is not well controlled during the production process, which will affect the washing effect.
How about hand sanitizer?
Nowadays, hand sanitizer is more and more popular among us, and many people like to carry a bottle with them when they travel.
1. Wash hands without water: easy to use and carry; Wash free, you can clean your hands anytime and anywhere;
2, continuation effect: the effect lasts for a long time, the effect can last 4-5 hours, up to 6 hours;
3, gentle skin care: with control hand oxidative stress level, prevent skin damage and hand protection effect, can moisturize and care for hand skin.
4, kill disease sterilization: After the Chinese Academy of Military Medical Sciences and Hubei Province disease prevention and control center training, inactivated virus, killing rate reached 99.99%.
Hand sanitizer contains two basic components:
1. Substances with disinfection effect. This refers to the killing effect of pathogenic biological causes, including fungi and viruses.
2. Substances that have skin care effects. The simplest and most typical recipe for hand sanitizer is 75% ethanol and 2% medical glycerin. Ethanol can be disinfected, glycerin moisturizing skin care, can be prepared by themselves.
3. The bactericidal rate of hand sanitizer reaches 99.99%, which is a great aid to physical health.
4, but the durable use can not stop the residue of chemical substances, in order to usually accept the traditional way, wash with soap and water is good.
Waterless hand sanitizer
Waterless hand sanitizer is a modern chemical inclusion;
Main identity: mineral oil, liquid wax, oleic acid soap, glycerin, pigment and other chemical identity;
The main effect: it plays a sterilization, disinfection, decontamination, no odor after use, neutral and does not hurt the skin, and the waterless hand sanitizer of individual manufacturers has a role in caring for the skin.
Usage: Pour a little of the liquid on your hands, rub your hands together, after the product is average, wipe it with a paper towel or towel (ethanol can be automatically volatilized).
Applicable: various hospitals, chemical plants, coal mines, and other things staff;
The main ingredients of the waterless hand sanitizer are biguanide surfactants and natural herbal extracts, etc., which have anti-bacterial (inhibitory) effects, and fungi are also useful. It has no toxic side effects on the human body, no irritation to the skin and mucous membranes, and it is an efficient external active anti-bacterial agent and neutral antistatic agent.
Hand sanitizer main components
(1) decontamination status
Decontamination is to provide decontamination and a thick foam, mainly anionic extrantants and a small amount of non-ionic and zwitterionic extrantants. Soap and sodium dodecyl sulfide were the first active agents used in hand sanitizers, but calcium soaps formed by their respective defects such as strong degreasing, high pH of soap and low resistance to hard water have become less used.
Non-ionic surfactants are also less commonly used in hand sanitizers, and a small amount of addition can improve the decontamination effect and improve the stability of the foam, such as cocoate diethanolamide, where the addition of alkyl glycosides can reduce the irritation of the surfactant on the skin. The addition of a small amount of zwitterions facilitates foaming and foams lasting, betaine and amine oxide.
(2) Caring nurse status
When washing hands, due to the degrease effect of the active agent, the skin is induced to dry after hand washing, so some fat-rich agents and emollients should be added to make up for the 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) Antibacterial status
Hands are always in contact with the outside world, hands will be contaminated with a variety of bacteria and even the presence of fungi, so the bactericidal components should have a broad spectrum, such as 3,4,4 ' monotrichloride Monohydroxyphenyl ether, chlorinated xylenol, Chinese herbal extracts, etc., in order to improve the bactericidal efficiency of the bactericidal agent, it is also necessary to add an additive to increase the penetration force, so that it can promote the bactericidal components to penetrate into the bacterial wall, fast bactericidal and enhance the bactericidal efficiency.
(4) The senses adjust identity
In order to make consumers more like and accept the hand sanitizer, give the hand sanitizer a special effect and appearance, add dye or pearlescent agent; In order to take advantage of the added thickener to adjust a suitable viscosity; In order to have a relaxed and pleasant feeling during the washing process, add an appropriate amount of fragrance.
(5) Natural identity
With the improvement of people’s awareness of safety and environmental protection, they double their admiration for green natural products, so many brands of hand sanitizer are choosing to add natural ingredients to the formula of hand sanitizer. These natural additives play a role in reducing irritation, moisturizing skin, antibacterial, antibacterial, and providing natural aroma and color, such as various plants, Chinese herbs, fruit extracts, etc. Aloe vera, silver apricot, chrysanthemum, ginseng, field seven, licorice, Moutan bark, tea fruit, sterilization and lemon and so on.
What are the dangers of using out-of-date hand sanitizer?
Bacteria such as pseudomonas aeruginosa that breed in outdated hand sanitizers can cause great harm to the human body.
It is understood that because pseudomonas aeruginosa is pathogenic bacteria, it can cause wound infection, pneumonia and other diseases, and its pathogenicity is very strong on the human body, and serious can cause suppurative septicemia; Staphylococcus aureus is also a highly pathogenic bacterium that can cause suppurative fumigation and septicemia. Mr. Li of the National detergent quality Monitoring and training Center reminds consumers to pay attention to the use of hand sanitizer in public places, the first thing to pay attention to is whether the hand sanitizer has odor, pungent odor, if there is, it may be that the product has crossed the warranty period or is the use of prohibited materials, this hand sanitizer is best not to use. Secondly, it is also necessary to investigate whether the hand sanitizer has stratification or oil and water dispersion signs, if so, the production enterprise does not control the emulsification process in the production process of the product, which will affect the washing effect, and it is best not to use.
