Dry mist hydrogen peroxide sterilization can replace formaldehyde fumigation space sterilization
In the disinfection of pharmaceutical factory workshop environment, many enterprises adopt formaldehyde fumigation disinfection and sterilization method, which is inexpensive and has excellent sterilization ability. However, the disadvantages of formaldehyde, such as high toxicity, strong harm, inconvenient operation, and harm to employee health, are being recognized and eliminated by more and more enterprises. Formaldehyde is prohibited in European pharmaceutical companies. The sterilization experts and practical application needs of Teling Biopharmaceutical Company have integrated new technology solutions for environmental disinfection in pharmaceutical factory workshops. This article introduces the advantages of using a dry mist hydrogen peroxide sterilizer for environmental disinfection in pharmaceutical workshops, and elaborates on the principle, composition, use, and validation of the Teling Biospace dry mist sterilization system. Analyzed the issues that should be noted when selecting space sterilization equipment for environmental disinfection in pharmaceutical workshops. The bactericidal effect, corrosiveness, and residual amount of hydrogen peroxide replacing formaldehyde were discussed in detail.
The application of hydrogen peroxide dry mist sterilization technology in European pharmaceutical workshop environment disinfection has a history of nearly 20 years. Especially in recent years, in the environment where formaldehyde usage is limited in the European Union, hydrogen peroxide dry mist sterilization technology has developed rapidly. The concept of hydrogen peroxide sterilization in pharmaceutical workshops was first proposed. Although it cannot be quickly popularized in all categories, the abandonment of formaldehyde sterilization by the European Union shows that the entire industry, whether managers or participants, is striving to find a product that can replace formaldehyde for sterilization.
Firstly, what is dry fog?
1. Dry mist size: Dry mist refers to a diameter less than 10 μ M.
2. Irregularity: Irregular movement of dry mist particles (Brownian motion principle);
3. Non coagulation: Dry droplets are not easily condensed together to produce large droplets;
4. Non adhesive: Dry mist particles will rebound when in contact with surfaces (such as walls), making them difficult to adhere.
The dry mist sterilization technology solution of Teling Biotech is a product of collaboration between aerodynamics experts and sterilization technology experts. It is developed using high-tech scientific technology, experimental simulation, technical verification, practical application, and pharmaceutical factory monitoring. Its main feature is to make air move at high speed under high pressure, collide with fungicides, and produce dry mist particles with a diameter of less than 10 microns. To achieve complete sterilization effect, kill harmful bacteria, and control harmful microorganisms, the technical solution of formaldehyde fumigation can be replaced.

Application scope of hydrogen peroxide sterilization in dry mist
1. Dry mist hydrogen peroxide sterilization can be safely used for disinfection and sterilization of clean room spaces and equipment. The application areas include pharmaceuticals, biotechnology, pharmaceutical product production, pharmaceutical workshops, cell rooms, microbiology rooms, sterile rooms, etc.
2. Dry mist hydrogen peroxide sterilization can be safely used for disinfection and sterilization at all levels: sterile clean workshops, sterile pharmaceutical workshops, microbiology rooms, sterile rooms, isolators, and sterile transfer rooms.
3. Dry mist hydrogen peroxide sterilization can be safely used for disinfection of surfaces and spaces such as stainless steel, plastic, glass, floors, walls, etc.
The placement of equipment follows the following principles:
The nozzle shall be kept away from the wall and equipment to avoid blurring spray and diffusion of easily dry fog.
Step 2: Secure the equipment, install an appropriate amount of disinfectant, and turn on the power.
Step 3: Turn off the air conditioning, let out fresh air, and close the doors and windows.
Step 4: Click the start button to start dry mist sterilization (please read the product manual before use)
Step 5: The equipment is sterilized. After the completion of spray, it will automatically stop quantifying, stand for 90 minutes, exhaust for 1 hour, and the sterilization is completed.
The entire disinfection process, from the start of disinfection to the safe entry of personnel, takes about 4-6 hours (including ventilation).
Validation of sterilization effect of hydrogen peroxide dry mist sterilization system
The sterilization effect of the hydrogen peroxide atomization sterilization system can be verified. According to the regulations of the Chinese Pharmacopoeia.
