How much alcohol is in hand sanitizer? Is alcohol-based hand sanitizer good?

Since the outbreak of the epidemic, protective products such as hand sanitizers have become must-have items for every family and business, and everyone now attaches great importance to hand cleaning and disinfection. So, how much alcohol content is necessary for hand sanitizer to be effective?

How much alcohol content is useful in hand sanitizer

Generally speaking, hand sanitizers with an alcohol concentration of ＞70% have better disinfection effects. Moreover, experts say that alcohol concentration of 70%-75% can kill the new coronavirus, and 75% is best. The reason why hand sanitizer can kill bacteria and disinfect without having to be washed is that its main ingredient is alcohol. Alcohol can not only disinfect and kill bacteria, but is also easy to evaporate, so hand sanitizer has become a hand washing tool. 75% alcohol has the best disinfecting effect, which is why the alcohol concentration of hand sanitizer must be high. Otherwise, it will not be able to disinfect and sterilize, let alone wash hands.

Alcohol content in hand sanitizer

It depends on the specific situation. Hand sanitizer is a product that is usually composed of water, alcohol, fragrance and glycerin, among which alcohol is the main bactericidal and disinfecting ingredient. The alcohol concentrations added to hand sanitizers produced by different manufacturers are different, so the alcohol content of hand sanitizers is not fixed. When choosing hand sanitizers, you also need to pay close attention to the alcohol concentration. However, the alcohol content of hand sanitizer is not low, at least above 50%.

The hand sanitizers on the market can be divided into two types according to their alcohol concentration. One is low-concentration alcohol-free hand sanitizer, and the other is high-concentration hand sanitizer. The alcohol content of low-concentration alcohol-free hand sanitizer is generally between 50%-60%, while the concentration of high-concentration alcohol-free hand sanitizer is between 60%-80%.

There are advantages and disadvantages. Hand sanitizer is a hand sanitizer that has both advantages and disadvantages. Its advantage is that it has a good disinfecting and sterilizing effect on hands. Compared with other hand sanitizers, the disinfection and sterilization will be more thorough, and it is quick and convenient, and does not require cleaning. It is very helpful for people in some special working environments, such as hospitals and other medical places, public places, etc. However, there are also disadvantages to using hand sanitizers. Because the alcohol concentration in hand sanitizers is high, it can easily cause certain effects on the skin. The skin on our hands has an absorption function. If we apply gel containing high concentration of alcohol on the skin for a long time, the skin on our hands will absorb some of it more or less, which will cause certain damage and irritation to the skin, and may cause symptoms such as dry skin and allergies. Therefore, we need to look at hand sanitizer objectively and correctly.
