如何合理选购洗手液 可从洗手液主要成分选择自己的产品



Hand sanitizer is more and more popular because it is mild and easy to use. But you know what? Unreasonable use of hand sanitizer will also bring harm to health, so we should know how to choose hand sanitizer. Let's learn about it with 360 common sense!


How to choose hand sanitizer?


Hand sanitizers on the market can be divided into three categories according to their different functions


The first type is common hand sanitizer, i.e. "liquid soap", which is mainly composed of detergent. Its use method is similar to that of soap, and only plays the role of cleaning and decontamination.


The second type is antibacterial hand sanitizer, which belongs to disinfection products. It is based on the common hand sanitizer, some antibacterial or bactericidal ingredients are added, which can kill the bacteria in the common hand sanitizer and skin wrinkles, and ensure the effect of hand sanitizer.


The third category is water-free hand sanitizer, which is mainly composed of alcohol and other disinfectants and skin care ingredients, and also belongs to disinfection products.


There are two points to pay attention to when choosing hand sanitizer:


1. Pay attention to the contents, that is, the hand sanitizer itself, and smell whether there is odor, pungent and other peculiar smell. If so, it may be that the shelf life has passed or banned raw materials have been used. It is better not to purchase and use them.


2. Observe whether there is stratification or oil-water separation. If there is, it indicates that the emulsification process is not well controlled in the production process, which will affect the washing effect.


How about hand sanitizer?


At present, hand sanitizer is more and more popular in our country. Many people like to take a bottle with them when they go out.


1. Wash hands without water: easy to use and carry; wash hands without water, clean hands anytime and anywhere;


2. Lasting effect: the effect lasts for a long time, lasting for 4-5 hours, up to 6 hours;


3. Gentle skin care: it can control the level of oxidative stress in the hand, prevent skin damage and protect the hand, moisturize and protect the hand skin.


4. Virus killing and sterilization: tested by the Chinese Academy of Military Medical Sciences and the center for Disease Control and prevention of Hubei Province, the killing rate of the virus was 99.99%.


There are two basic components in hand sanitizers:


1. A substance with a disinfecting effect. This refers to the killing effect on pathogenic biological factors, including fungi and viruses.


2. Substances with skin care function. The simplest and most representative formula is 75% ethanol plus 2% medical glycerin. Alcohol can disinfect, glycerin can moisturize skin care, and it can be completely prepared by yourself.


3. The sterilization rate of hand sanitizer reaches 99.99%, which is of great help to health.


4. But it is inevitable that there are chemical residues in long-term use, so it is usually better to adopt traditional methods and wash with soap and water.


Hand Sanitizer


Water free hand sanitizer is a kind of modern chemical mixture;


Main ingredients: mineral oil, liquid wax, oleic acid soap, glycerin, pigment and other chemical components;


Main functions: it can sterilize, disinfect and decontaminate. After use, it has no peculiar smell, neutral and does not hurt the skin. The anhydrous hand sanitizer of some manufacturers also has a nursing effect on the skin.


Usage: pour a little of the liquid on your hands, rub each other's hands, and after the product is even, wipe it with a paper towel or towel (ethanol can be evaporated automatically).


Application: all kinds of hospital, chemical plant, coal mine, etc;


The main ingredients of anhydrous hand sanitizer are biguanidine surfactants and natural herbal extracts, which have the effect of anti bacteria and fungi. It has no toxic and side effects on human body, no stimulation on skin and mucous membrane. It has high-efficiency surface active anti bacteria agent and neutral anti-static agent.


Main components of hand sanitizer


(1) Decontamination ingredients

去污成分是为提供去污作用和丰富的泡沫,主要是阴离子表面活性剂以及少量的非离子和两性离子表面活性剂。 阴离子表面活性剂有皂、十二烷基硫酸钠、Q一烯烃磺酸盐、脂肪醇聚氧乙烯醚硫酸 盐、Q一磺基脂肪酸脂、月桂酰肌氨酸盐和单油酸酰胺磺基琥珀酸二钠等。皂和十二烷基硫 酸钠是最早使用于洗手液的表面活性剂,由于他们各自的缺陷如较强的脱脂性,皂的高pH 值及低的抗硬水性能形成的钙皂,已较少使用了。

Decontamination ingredients are designed to provide decontamination and rich foam, mainly anionic surfactants and a small amount of non-ionic and zwitterionic surfactants. Anionic surfactants include soap, sodium dodecyl sulfate, q-olefin sulfonate, fatty alcohol polyoxyethylene ether sulfate, q-sulfonyl fatty acid ester, lauroyl sarcosinate, monosodium monooleamide sulfosuccinate, etc. Soap and sodium dodecyl sulfate are the first surfactants used in hand sanitizer. Due to their respective defects such as strong degreasing, high pH value of soap and low resistance to hard water, calcium soap has been less used.

非离子表面活性剂一般较少在洗手液中使用,少量的加入可以增进去污作用和提高泡沫 的稳定性,如椰油酸二乙醇酰胺,其中烷基糖苷的加入可以降低表面活性剂的对皮肤的刺激。少量的两性离子加入有利于发泡和泡沫的持久,甜菜碱和氧化胺。

Nonionic surfactants are generally less used in hand sanitizers. A small amount of additives can enhance detergency and foam stability, such as coconut fatty acid two ethanol amide. The addition of alkyl polyglycosides can reduce the skin irritation of surfactants. A small amount of zwitterionic addition is beneficial to foaming and foaming lasting, beet and amine oxide.


(2) Nursing ingredients

洗手时,由于表面活性剂的脱脂作用,使得手洗后皮肤感到干燥,因此要加入一些富脂 剂和润肤剂,补充皮肤油脂防止皮肤干燥粗糙,如各种天然与合成的羊毛脂、甘油、丙二 醇、山梨醇、乳酸盐和吡咯烷酮羧酸钠等。

During hand washing, 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 supplement skin oil to prevent skin from drying and roughness, such as various natural and synthetic lanolin, glycerin, propylene glycol, sorbitol, lactate and sodium pyrrolidone carboxylate.


(3) Antimicrobial components

手时刻都在接触外界,手上会沾染上各类的细菌甚至有真菌的存在,因此杀菌组分要有 广谱性,如3,4,4'一三氯一2'一羟基苯醚、氯代二甲苯酚、中草药提取物等,为了提高杀菌剂 的杀菌效率,还需要添加增加渗透力的助剂,使其促进杀菌组分渗透进细菌壁,快速杀菌,增强杀菌效率。

Hands are always in contact with the outside world, and hands will be contaminated with various kinds of bacteria and even fungi. Therefore, sterilization components should be broad-spectrum, such as 3, 4,4'trichloro-2'hydroxybenzene ether, chloroxylenol, Chinese herbal extracts, etc. in order to improve the bactericidal efficiency of fungicides, it is also necessary to add additives to increase the penetration force, so as to promote the penetration of bactericidal components into the bacterial wall, fast sterilization and enhance the bactericidal efficiency.


(4) Organoleptic components

为了让消费者更喜欢和接受洗手液,给洗手液赋予特殊的效果和外观,加人染料或珠光 剂;为了取用的方便添加增稠剂调整一个合适的黏度;为了在洗手过程中有一种轻松愉悦的感受添加适量的香精。

In order to make the consumers love and accept the hand washing liquid, give the hand washing liquid special effect and appearance, add dye or pearlescent agent; adjust the suitable viscosity for the convenience of adding the thickener; add a certain amount of essence to the feeling of pleasant and pleasant feeling during the process of washing hands.


(5) Natural ingredients

随着人们安全、环保意识的提高,对绿色天然产品更加崇尚,因此在洗手液配方中加入 天然原料是许多洗手液品牌的选择,这些天然添加剂起到了降低刺激、滋润皮肤、抗菌、抑 菌、以及提供天然的香气和色泽的作用,例如各种植物、中草药、水果提取物,芦荟、银 杏、菊花、人参、田七、甘草、牡丹皮、茶果、杀菌和柠檬等等。

With the improvement of people's awareness of safety and environmental protection, green natural products are more popular. Therefore, adding natural materials into the formula of hand sanitizer is the choice of many hand sanitizer brands. These natural additives can reduce irritation, moisten skin, resist bacteria and inhibit bacteria Bacteria, as well as the role of providing natural aroma and color, such as various plants, Chinese herbal medicine, fruit extract, aloe, ginkgo, chrysanthemum, ginseng, Tianqi, liquorice, peony skin, tea fruit, sterilization and lemon, etc.


What are the hazards of using expired hand sanitizer?


Bacteria such as Pseudomonas aeruginosa can cause great harm to human body.


It is understood that due to Pseudomonas aeruginosa as the pathogenic bacteria, it can cause wound infection, pneumonia and other diseases, with strong pathogenicity to human body, and can cause septic septicemia in serious cases; Staphylococcus aureus is also a very strong pathogenic bacteria, which can cause septic infection and septicemia. Mr. Li from the national washing product quality supervision and inspection center reminded consumers that when using hand sanitizer in public places, first of all, they should pay attention to whether the hand sanitizer has smell, pungent smell and other peculiar smell. If there is any, it may be that the product has exceeded the shelf life or the prohibited raw materials are used. This kind of hand sanitizer should not be used. Secondly, it is also necessary to observe whether there is stratification or oil-water separation of hand sanitizer. If there is, it indicates that the production enterprise does not control the emulsification process in the production process, which will affect the washing effect, and it is better not to use it.
