Not all hand sanitizers can be sterilized ?
After the resumption of work in various places, no matter at the door of the company or the community, disinfectant hand sanitizer is indispensable. Our hands are almost always in contact with things. If you do not wash your hands in time, bacteria and harmful substances are likely to pass through the mouth or eyes to induce corresponding diseases. Therefore, it is also necessary to have disinfectant hand sanitizer at home.
However, there are so many hand sanitizers on the market, not every hand sanitizer has sterilization function. According to standards, hand sanitizers on the market are roughly divided into three categories.
1. Ordinary hand sanitizer
Ordinary hand-washing liquid can be said to be a liquid version of soap. The detersive ingredients are mainly anionic surfactants and a small amount of nonionic and zwitterionic surfactants. This type of hand sanitizer usually cleans and decontaminates. The national standard has no specific requirements for the sterilization effect of ordinary hand sanitizers, only requiring that the bacteria in the hand sanitizers should not exceed the standard.
2. Antibacterial / bacteriostatic hand sanitizer
Antibacterial / bacteriostatic hand sanitizer is the addition of antibacterial or bactericidal ingredients to ordinary hand sanitizer, which has obvious killing or inhibiting effects on common pathogenic bacteria such as pyogenic cocci, intestinal pathogens, and pathogenic fungi . After SARS, this type of hand sanitizer has emerged in large quantities, which is suitable for use in public places with high traffic such as hospitals, shopping malls, supermarkets, and bus stations.
3. Hand sanitizer (disinfectant supplies)
This third category is no-clean hand sanitizer. These are basically sterilization and disinfection products, mostly in the form of spray or gel, and the main sterilization component is generally alcohol. Easy to use because no flushing is required.
So, how do we distinguish which disinfectant hand sanitizer is really effective?
1.Look at the product license number
Look directly at the product license number on the back of the product packaging:
Wei Xiaozheng, hand sanitizer belongs to the category of disinfection products
This type of hand sanitizer can help kill or inhibit common pathogenic bacteria, such as pyogenic cocci, intestinal pathogens, and pathogenic fungi. This type of hand sanitizer needs to be sent to the product for inspection, after a series of strict safety and disinfection effect tests, and after obtaining a sanitation license and “Hui Xiaozheng” approval approval, production and sales are allowed.
Hygiene makeup standard, lotion hand lotion belongs to the category of cosmetics
It does not necessarily have sterilization and bacteriostatic effects, its function is only qualified for cleaning and decontamination.
2. Look at the ingredients
The authentic disinfectant hand sanitizer must have relevant active ingredients in the formula. Most of the effective antibacterial hand sanitizers on the market can be basically divided into alcohols and non-alcohols.
Everyone knows that alcohol can be disinfected, provided that at a certain concentration, usually 70% to 75% concentration can kill viruses and bacteria more efficiently, so the concentration of alcohol-based hand sanitizer on the market is usually in this range Inside.
Because alcohol has good water solubility, strong surface activity and strong volatility, it is also an important solvent for no-clean hand sanitizer, so you will see that many no-clean hand sanitizers contain alcohol, which is very convenient to use
However, alcohol is not suitable for large-area contact, especially wounded skin, which can cause irritation and prone to dry skin after long-term use. Therefore, there are many brands that add moisturizers and other ingredients to sterilize while protecting the hands from dry skin.
Para-chloro-xylenol is a type of phenol (Phenols). It is a broad-spectrum antifungal and antibacterial agent. It has a good killing effect on most Gram-positive and negative bacteria, fungi and mold.
However, para-chloro-dimethylphenol generally has moderate to low toxicity, will cause severe eye irritation, low toxicity through inhalation through the breathing channel, in addition will cause slight skin irritation, and will also pollute the environment unfavorable. Although it is a hooligan not to talk about the dosage and the toxicity, after all, it is also accumulated, and it is not recommended to use it for a long time.
Benzalkonium chloride (BAC for short) is the most frequently used quaternary ammonium salt in household cleaners.
Benzalkonium chloride is a cationic surfactant. It is a broad-spectrum fungicide. It can change the permeability of bacterial cytoplasmic membranes, make the cytoplasmic material of the bacteria extravasate, hinder its metabolism and play a killing role. It is a household sterilization product. The most widely used quaternary ammonium salt. Common disinfection ingredients of quaternary ammonium salts include benzalkonium chloride, benzalkonium bromide, and benzethonium chloride.
Benzalkonium chloride is often used for wound cleaning, has a broad-spectrum, high-efficiency sterilization ability, stronger and safer than alcohol sterilization. In case the concentration does not exceed 0.1%, infants can also use it with peace of mind.
It is worth mentioning that benzalkonium chloride has a strong effect on Gram-positive bacteria and is not effective against Pseudomonas aeruginosa, acid-fast bacillus and cell spores. It is also ineffective against this new coronavirus.
The biguanide disinfectant components mainly include chlorhexidine gluconate and polyhexamethyleneguanidine, etc. It is a new generation of disinfectant.
Chlorhexidine gluconate is a biguanide chlorobenzene, has a fairly wide range of antimicrobial activity. At pH 5.0 to 8.0, it is most effective against Gram-positive (10mcg / ml) and Gram-negative (50mcg / ml) bacteria.
Polyhexamethylene guanidine is an environmentally friendly high-molecular polymer sterilization disinfectant with a broad antibacterial spectrum. It is effective against Gram-positive and negative bacteria and mold. It is colorless, odorless, non-irritating to the skin, and non-toxic , Non-corrosive characteristics.
Its antibacterial effect is mainly through dissolving lipids, changing the permeability of bacterial cell membranes, and making the metabolism in the bacteria body obstacles and antibacterial. So it is actually better for disinfecting wipes.
In the above, although there are many commonly used disinfecting ingredients, there are not many ingredients that are really suitable for making hand sanitizer. Everyone remembers the above points when choosing a product, just choose as appropriate
