On the evening of January 20, the National Health Commission confirmed the first confirmed case of pneumonia from an imported novel coronavirus infection in Shanghai. In the face of the ongoing epidemic, many citizens know that they should wash their hands regularly, but are confused as to how to choose in the face of the wide range of hand sanitizers available. Here’s a look at it together. A. Distinguish the types of hand sanitizer Hand sanitizer can be divided into three main categories according to different functions: ordinary hand sanitizer, anti (anti) bacterial hand sanitizer and hand sanitizer free (including disinfectant gel, etc.). The main role of ordinary hand sanitizer is to decontaminate and clean, can effectively reduce the number of hand pathogenic microorganisms; anti (anti) bacterial hand sanitizer, divided into antibacterial and antibacterial type, in addition to decontamination and cleaning, there are certain bactericidal, antibacterial effect; hand sanitizer (including the first disinfectant gel) should comply with the “GB27950-2011 hand sanitizer hygiene requirements”, take an appropriate amount of hand sanitizer in the palm of your hand, rub your hands together Make evenly coated with each part, the role of 1-5 minutes, can effectively kill hand pathogenic microorganisms, the use of relatively simple. Second, distinguish between the “health and consumer certificate word” and “health and makeup quasi-word” ordinary hand sanitizer and anti (anti) bacterial hand sanitizer in the appearance of the liquid almost no difference, basically transparent or colored viscous liquid, free hand sanitizer is generally transparent. To distinguish whether there is a disinfection effect of hand sanitizer, you can distinguish through the product lot number: 1, “health and disinfection certificate word” hand sanitizer belongs to the disinfection products. This type of hand sanitizer can kill or inhibit common pathogenic bacteria, such as septic cocci, intestinal pathogenic bacteria, pathogenic fungi and so on. This type of hand sanitizer needs to be sent for inspection, after a series of strict safety and disinfection tests, to obtain a health license and “health and disinfection certificate word” permit approval, before allowing production and sales. 2, “health and makeup” hand sanitizer belongs to cosmetics. “Health makeup quasi-letter” is the health department for domestic cosmetics issued by the approval number, such hand sanitizer generally does not have sterilization, antibacterial effect, and ordinary shampoo, facial cleanser is the same general skin care cosmetics, its function can only achieve the purpose of cleaning, decontamination. Third, how to buy hand sanitizer? 1, to buy from the regular mall. The regular shopping malls have a stable channel of purchase and a more stringent gatekeeping system to ensure product quality. 2, observe whether the packaging is intact, whether the printing on the packaging bottle is clear, whether the pump head is strong. General hand sanitizer by squeezing the pump head out of the liquid, if the packaging quality is not qualified, will not be in the process of using the liquid or leakage, causing inconvenience and waste. 3, check whether the logo is complete, such as the availability of the factory name, factory address, etc., pay special attention to whether there is a standard number. Although there is no unified national standard for hand sanitizer, but the state does not allow the production of no standard, so the manufacturers to develop corporate standards, and on the packaging indicates the corporate standard number to ensure product quality. 4, pay attention to the hand sanitizer itself has no odor, pungent and other odors. If there is an odor, it may be out of shelf life or the use of prohibited raw materials, do not buy or use, but also to observe whether there is stratification or oil-water separation phenomenon, such as the appearance of these phenomena indicate that the production process of emulsification process is not well controlled, will affect the washing effect. 5, check the formulation of hand sanitizer. When buying hand sanitizer, pay attention to check the active ingredient content marked on the label. Some hand sanitizers are labeled with the content of ethanol, paraben and isopropyl alcohol instead of alcohol. It is important to note that in either form, the conversion to alcohol content should be between 60% and 95%. If the content is lower than 60%, it will not be effective in killing viruses and bacteria, and if it is higher than 95%, the germicidal effect will be inhibited. Fourth, the prevention and control of new coronavirus, which hand sanitizer to choose? In the face of the new coronavirus, it is recommended to wear a mask, wash hands regularly, go to less crowded public places, do not contact wild animals, cook food thoroughly, and exercise properly to enhance resistance. When it is inconvenient to wash hands or if hands are not obviously contaminated, hand sanitizer can also be used for hand decontamination.
