You can wash your hands by rubbing your hands with an alcohol-based solution or by washing your hands with soap and clean water. For good hand hygiene, we must know the characteristics of each chemical used in hand hygiene.

From there, we use them appropriately in specific situations to achieve high efficiency in the prevention of hand disease, foot-and-mouth disease, gastrointestinal diseases, hepatitis A, E …, helminths.

Natural soap (hereinafter collectively referred to as soap)

Soap has become an indispensable tool for personal hygiene in our daily life. Soap is a compound containing esterified fatty acids and sodium or potassium hydroxide with a detergent function.

Thanks to the detergent contained in the composition, the soap has a cleaning function. These detergents have a high surface tension, which removes dirt and organic matter from the hands.

The soap contains no antibacterial active ingredient, so it has little or no antibacterial activity. Washing your hands with soap will help remove the bacteria, fungi and parasites that live on your skin.

These are germs that can easily be transferred to become germs responsible for diseases dangerous to health. According to the US Centers for Disease Control and Prevention, washing hands with hot water and soap increases the effectiveness of germs control. However, washing your hands with soap does not remove bacteria that are deposited in the epidermis, so it does not eliminate all the pathogens on the hands.

Soap comes in different forms: cake, liquid or powder. Even if your skin has been reconstituted and prepared at a neutral pH, washing your hands with soap and water can cause side effects such as irritated dermatitis or dry skin. The soap at home is safer and less bacterial because fewer people use it.

Therefore, simply clean the soap before using it to reduce the bacteria. At the same time, it is necessary to keep the soap in a box with a lid and a drainage hole so that the soap stays dry. According to the US Centers for Disease Control and Prevention, liquid soap is home to more germs.

Therefore, the liquid soap must be well preserved. If you want to reuse a soap dispenser, wash it thoroughly before adding new soap. Therefore, in public places, the best way to prevent soap pollution is to provide liquid soap in a closed container with a dosing pump.
