Conventional medical hydrogen peroxide can kill intestinal pathogens and pyogenic cocci, and is generally used for surface disinfection.
The scientific name of hydrogen peroxide is hydrogen peroxide, and its molecule is composed of 2 hydrogen atoms and 2 oxygen atoms. The chemical formula is H2O2. It can be seen from the chemical formula that there is one more oxygen atom in the molecule than in the water molecule. Hydrogen peroxide is a colorless liquid with a pungent odor.
3% hydrogen peroxide is commonly used in medical treatment for wound or otitis media disinfection. 3% hydrogen peroxide has the ability to disinfect and sterilize. Because peroxides are unstable, the following reactions are prone to occur: H2O2→H2O+(O) When it meets skin, oral and mucosal wounds, pus or dirt, it immediately decomposes to generate oxygen . This kind of oxygen atoms, which have not been combined into oxygen molecules, has a strong oxidizing ability. When it comes in contact with bacteria, it can destroy the bacterial cells and kill the bacteria. Hydrogen peroxide has a strong oxidizing effect, but the concentration of medical hydrogen peroxide is only 3%. It is only a little burning when applied to the skin, and the surface is oxidized to white. It is enough to wash with water, and the original skin tone will be restored after 3 to 5 minutes. When the hydrogen peroxide is disinfected, there will be small white bubbles generated because the hydrogen peroxide will decompose when it meets the dust and dirt on the fingers, and decompose to produce water and oxygen. After killing the bacteria, the remaining substance is water without any poison or irritation. Will not form secondary pollution. Therefore, hydrogen peroxide is an ideal disinfectant for wound disinfection. But do not use too high concentration of hydrogen peroxide for wound disinfection to prevent burns to the skin and the affected area.
