How does antibacterial hand gel? Source:

In the childhood of each of us were taught to wash their hands before eating. Most likely, such a rule could seem tedious and useless, but its implementation helps to protect our body from infections. If soap and water are not available, help can come in various disinfectants, whose main principle is due to the presence in amounts of alcohol. However, in what way is work so necessary to modern man liquids and gels?

How to properly sanitize your hands?

modern man, leading an active way of life in the metropolis, is often under threat, if only because we are not always able to clean your hands against various germs which surround us everywhere outside the door of the apartment. In order to reduce the risk of infectious diseases in that moment when you don't have soap and water, were created by the various disinfectant liquids and gels for hands. The need for their use arises especially acutely after a visit to public transport or places with large crowds, even accidentally grabbing hold of something in such places, we run the risk of catching an invisible bacteria, including already famous worldwide coronavirus.

The Main ingredient of all modern disinfectants for hands is ethyl alcohol, but it is sometimes replaced by isopropyl alcohol or benzalkonium chloride. The main advantage of alcohol over other substances is their ability to interfere in the metabolic processes of the cells, destroying the protein chains and thereby ensuring the destruction of harmful microorganisms.

In order to test the effectiveness of disinfectants, the researchers conducted several case studies, according to the portal . Their results showed that alcohol antiseptics for hands become effective only if the content of alcohol exceeds 30%. It is also logical that with increasing alcohol concentration, also increasing speed . But can antiseptic be a substitute for a hand washing?

whether the hand gel to replace washing them?

Anyway, despite the wide range of effects alcohol antiseptics for hands, to ensure 100% protection from germs, they still can't, although able in some way to replace hand washing. It turned out that antiseptics containing ethanol in high concentrations, much more efficient to eliminate pathogenic bacteria such as Escherichia coli and Staphylococcus saprophyticus, even compared to a full hand wash. However, some types of dangerous viruses still survive even at high concentrations of alcohol, and the inability of the antiseptic to clean our hands from contamination and elemental dust significantly reduces their effectiveness. That is why in the struggle between the wash and the winner is the good old method of disinfection of hands with water and soap.

hand Wash effectively fights dirt than antibacterial gels

Harmful antiseptic gels?

As mentioned above, antiseptic hand gels effectively destroyed , if the concentration of alcohol in their composition exceeds 30%. However, from the school chemistry course you may be aware that alcohol has the ability to evaporate, reducing the efficiency of gel with each use. The question arises: is not harmful if prolonged and frequent exposure of alcohol to the human skin?

And you think antiseptic gels are more effective than hand washing? Share your opinion on

The Scientists were able to answer this question. Because alcohols are considered safe when applied topically, and often do not cause any negative effect on the skin, the only negative point could increase dryness or a slight irritation of the skin. In any case, during the season of influenza and SARS mild drying of the skin may be the least of all evils: it is better to be healthy, but with a slightly dried skin than patients with dirty hands.
