In order to overcome the problems caused by traditional sterilization methods: poor sterilization effect, high corrosiveness to equipment and harm to human body, hydrogen peroxide space sterilization equipment came into being.
Hydrogen peroxide, an effective disinfectant
First, hydrogen peroxide is a naturally occurring chemical that is widely present in air and water. As early as the 18th century, humans discovered and began to use hydrogen peroxide, which is widely used in food, beverages, medical devices, and healthcare. The use of hydrogen peroxide mainly depends on the degree of oxidation, and different concentrations of hydrogen peroxide have different uses.
The concentration of ordinary medical hydrogen peroxide (commonly known as hydrogen peroxide) is 3%, which is mainly used to disinfect wounds or otitis media. If there are wounds, pus or dirt on the skin, mouth and mucous membranes, it will immediately decompose into oxygen. Oxygen does not combine with oxygen molecules and has a strong oxidizing ability. When it comes into contact with bacteria, it kills bacteria and kills them

. What remains after killing the bacteria is water and oxygen without any toxicity or irritation. There will be no secondary pollution and drug resistance. Therefore, medical hydrogen peroxide is an ideal wound disinfectant.
The concentration of industrial hydrogen peroxide is usually 25-50%. High concentrations of hydrogen peroxide are highly corrosive and present an explosion hazard. If the concentration exceeds 8%, it needs to be packaged and shipped in special containers. When disinfecting with liquid hydrogen peroxide, high concentrations and prolonged exposure are required to kill highly resistant microorganisms such as bacterial spores and fungi. For example, when using 7.5% hydrogen peroxide disinfectant produced by Reckitt Benckiser (approved by the FDA for advanced surface disinfection), the disinfection time at 20°C is 6 hours.
