The main function of hand sanitizer is to clean and protect skin. Some specific ingredients can play the role of disinfection and sterilization. Therefore, not all hand sanitizers have bactericidal effect.

Hand sanitizer is divided into ordinary type and antibacterial type. A simple method can distinguish whether hand sanitizer has bactericidal effect or not: identify "Wei Xiao Zheng" and "Wei Zhuang Zhun".

"Wei Zhuang Zhun Zi" is the approval number issued by the cosmetics testing department of the National Health Commission for domestic cosmetics. The hand sanitizer with the batch number of "Wei Zhuang Zhun Zi" belongs to the category of cosmetics and does not have the efficacy of sterilization and bacteriostasis. The hand sanitizer of "Wei Zhuang Zhun Zi" and ordinary shampoo and facial cleanser belong to general skin care and cosmetic products, which can only achieve the purpose of cleaning and decontamination.

"Weixiaozhengzi" hand sanitizer increases the bactericidal effect on the basis of cleaning, and can help kill or inhibit common pathogenic bacteria, such as pyogenic cocci, intestinal pathogenic bacteria, pathogenic fungi, etc. This kind of hand sanitizer needs to be submitted for inspection. After a series of strict safety and disinfection effect tests, it is allowed to be produced and sold only after obtaining the hygiene license and the approval document of "weixiaozheng". It is suitable for special people, such as doctors, cashier, etc., as well as special occasions, such as hospitals, hotels, public toilets, etc.
