Description
Technical Field

Background
Bacteria are the most common species in pathogen infection, and can cause lesions in every living aspect, such as skin, respiratory tract, food, vegetation soil, etc. Common bacteria that can cause infection are staphylococcus aureus, haemolytic streptococcus, pseudomonas aeruginosa, escherichia coli, anaerobic bacteria, and the like. The traditional disinfecting article is mainly used for killing pathogenic microorganisms on a transmission medium, so that the pathogenic microorganisms can reach harmless requirements, the pathogenic microorganisms are killed outside an in-vivo environment, the transmission path of infectious diseases is cut off, and the purpose of controlling the infectious diseases is achieved. However, the conventional disinfectant products often have a lot of ignored or accepted damages in use, such as very harsh odor generation, cell mutation caused by long-term contact, skin irritation and even burn, and adverse reactions such as cough, chest distress, shortness of breath and the like after a large amount of inhalation; while more serious ones only require very small doses, by being combined with the evaporation of water vapor in the air, some carcinogens can be released and even directly lead to allergic reactions in the human body. The traditional disinfection method is easy to take effect quickly, and the aim of simple process is widely applied in the field of sanitation. Unlike traditional disinfectant, the bacteriostatic agent is not designed to kill most pathogens in the environment rapidly and effectively at one time, so that the toxicity and potential hazard are much smaller. Bacteriostats act by inhibiting bacterial growth. Bactericides destroy the bacterial cell structure, resulting in bacterial death. The antibacterial agent can kill bacteria, is widely applied to various fields of antibiosis, mildew prevention, disinfection and the like due to high safety and antibacterial effect, and is an ideal antibacterial agent for gynecological lotion, wet tissues, sanitary towels, oral supplies, hand sanitizers, melon and fruit fresh keeping and disinfection, environmental disinfection and the like. While bactericides may control or kill microorganisms, bacteria, fungi, and algae in aqueous systems. The main fields are agricultural bactericides and industrial bactericides. Therefore, the characteristics of low residue and low harm of the bacteriostat, low cleaning strength, strong efficacy of the bacteriostat, overlarge harm and easy dispersion result in two difficulties in selecting the sterilizing articles. The invention aims to provide a design thought, and on the premise of not changing low residue and low harm, the pathogen killing performance of the bacteriostat is improved as much as possible, and the application field and environment of the bacteriostat are widened.
