We all know that hand sanitizer is a relatively popular cleaning product. It can have a very good sterilization effect. Many people often use hand sanitizer to wash their hands. There are many types of hand sanitizers, and hand sanitizer is one of the more common ones. So does hand sanitizer contain alcohol?
Do hand sanitizers contain alcohol?
Hand sanitizers generally contain alcohol.
The main active ingredient of the hand sanitizer is alcohol or benzalkonium chloride. Alcohol is a common sterilant and disinfectant in medical and other fields, while benzalkonium chloride is a non-oxidative bactericide with broad-spectrum and efficient bactericidal ability. , commonly used in industrial and medical disinfection, band-aids and other products also have this ingredient. Therefore, whether it is an alcohol-based hand sanitizer or a product with benzalkonium chloride as the main active ingredient, it can meet basic needs in terms of cleaning and sterilization.
Alcohol is a commonly used disinfectant ingredient in the medical field. It is extremely volatile and has little skin irritation. However, in the hand sanitizer containing benzalkonium chloride, the composition of benzalkonium chloride is very small and the concentration is extremely low, which generally does not cause irritation to the skin. In addition, skin care ingredients such as glycerin and lipids are usually added to the hand sanitizer. After cleaning, it will protect the skin to a certain extent. Therefore, the use of the hand sanitizer will generally not cause damage to the skin.
How much alcohol does hand sanitizer contain
It is better to use a hand sanitizer containing 60%-95% alcohol.
The study found that hand sanitizers containing 60%-95% alcohol were more effective at killing bacteria than low-alcohol hand sanitizers and alcohol-free hand sanitizers. Alcohol-free hand sanitizers don't remove as many types of germs as alcohol-based hand sanitizers, usually only inhibit the growth of bacteria rather than kill them, and are more likely to cause skin irritation.
Most alcohol-based hand sanitizers on the market have a concentration of 60%-70%. Although they cannot be carried on board, they can be checked, but each bottle cannot exceed 500 ml.
To effectively kill germs, hand sanitizers have an alcohol concentration of at least 60%. Disposable hand sanitizer ethanol (that is, alcohol) is the main ingredient, and it does have a certain antibacterial effect, but long-term use will irritate the skin, dry skin and cause chapped.
Alcohol-free or alcohol-free hand sanitizer
There is also an alcohol-free hand sanitizer on the market, so it uses some chemical ingredients to kill bacteria. These chemicals may cause skin irritation in children with sensitive skin. For improper use, it will also cause great danger.
More importantly, although the bacteria are killed, their remains are still in the hands of children, and children will still eat these chemical components and bacterial remains into their stomachs through contact.
For example, trimethylammonium chloride is generally used for sterilization and disinfection. However, in the "Chemical Safety Data Sheet", its hazard overview is clearly stated:
1. Harmful if swallowed.
2. Causes severe skin burns and eye damage.
3. This manual also points out first aid measures:
4. Inhalation: If inhaled, move the patient to fresh air.
5. Skin contact: Remove contaminated clothing and rinse skin thoroughly with soap and water. If you feel unwell, seek medical attention.
6. Eye contact: Separate the eyelids and rinse with running water or normal saline. Get medical attention immediately.
7. Ingestion: Rinse mouth, do not induce vomiting. Get medical attention immediately.
So don't assume that non-alcoholic hand sanitizers are foolproof.
Can hand sanitizer replace alcohol?
Hand sanitizers are available in both alcohol and non-alcoholic varieties. Although alcohol can be sterilized and disinfected, its effect can only kill a small part of the bacteria. The sterilization method is to kill and reduce through alcohol, and alcohol is volatile, and the action time of hand washing is short, so the antibacterial effect is far from being achieved. 99.9%.
In addition, the alcohol content of some disposable hand sanitizers is generally between 55% and 65%. Compared with the 75% alcohol content of medical hand sanitizers, the concentration is not so high, so the antibacterial effect is not so good. So it is not a substitute for alcohol.
