Hand sanitizers have become an essential item for many people worldwide due to the COVID-19 pandemic. But what exactly are these gels and how do they work? In this article, we will explore everything there is to know about hand sanitizers.
What is a hand sanitizer?
A hand sanitizer is a disinfectant product used to reduce the amount of germs present on the skin of hands. These products typically contain ethyl or isopropyl alcohol, which is an effective disinfectant against many types of bacteria, viruses, and fungi.
How do hand sanitizers work?
When a hand sanitizer is applied to the skin, the alcohol in the product acts by dissolving the lipid membrane of germs, destroying their protective shell, and killing them. As alcohol takes some time to evaporate completely, it is important to continue rubbing the product on the hands until they are completely dry.
When is it appropriate to use a hand sanitizer?
Hand sanitizers are useful in many situations, such as when there is no access to water and soap or when the amount of germs on hands needs to be reduced. Some examples include:
After touching public objects such as door handles, banknotes, keyboards, etc. Before eating or preparing food After sneezing, coughing, or blowing one’s nose After using the toilet
How to properly use a hand sanitizer?
To properly use a hand sanitizer, follow these steps:
Dispense an adequate amount of product into the palm of the hand (the amount varies depending on the brand of the product). Rub the product onto the hands for at least 20-30 seconds, making sure to cover all surfaces of the hands and fingers. Continue rubbing until the product is completely dry. It is important to note that hand sanitizers are not a substitute for washing hands with water and soap. When possible, it is always better to wash hands with water and soap for at least 20 seconds.
Conclusion
In summary, hand sanitizers are an effective product for reducing the amount of germs present on the skin of hands. However, it is important to use them properly by following the manufacturer’s instructions and always wash hands with water and soap when possible. The use of hand sanitizers can contribute to keeping hands clean and reducing the risk of infections.
