The ideal disinfectant should have a broad bactericidal spectrum, strong bactericidal ability, fast action speed, good stability, low toxicity, corrosiveness, and low irritation (should be non-toxic, no residue, no corrosion, no irritation), and easily soluble Water, safety to humans and animals, low cost and easy access, and low environmental pollution. In the future, relevant scientific research and production units should research and develop new disinfectants from various aspects and angles according to market needs from the synthesis of new compounds, solvent selection, reasonable compounding, production processes, etc., to comprehensively improve the scientific and technological content of disinfectants in China, and develop the disinfectant industry. At the same time, it will provide more and better products to the society, meet the needs of epidemic control and market needs, and benefit humanity.
The bactericidal mechanism is the release of new ecological atomic oxygen and the active groups in the oxidizing bacteria. The sterilization is characterized by fast and strong action, which can kill all microorganisms, including bacterial spores and viruses. Surface disinfection is the main type, such as chlorine dioxide, hydrogen peroxide, ozone, sodium hypochlorite, etc. This type of disinfectant is a sterilant.
The bactericidal mechanism is to denature or alkylate the protein; the sterilizing feature is effective against bacteria, spores, fungi, and viruses. But the temperature has a greater effect. Such as formaldehyde and glutaraldehyde. This type of disinfectant can be used as a sterilant.
The bactericidal mechanism is to denature, precipitate or inactivate the enzyme system; bactericidal characteristics are effective against fungi and some viruses.
The bactericidal mechanism is to denature proteins and interfere with metabolism; bactericidal characteristics are effective for bacteria and ineffective for spores, fungi and viruses, such as ethanol and ethylpropanol. This type of disinfectant is a medium-effect disinfectant and can only be used for general disinfection.
Alkali and salt
The bactericidal mechanism is to denature, precipitate or dissolve the protein; sterilization is characterized by its ability to kill bacterial propagules, bacterial spores, viruses and some hard-to-kill microorganisms. Strong bactericidal effect and strong corrosiveness, such as sodium hydroxide, calcium oxide, salt (non-corrosive), etc. Generally can only be used as preventative disinfectant and sterilizing washing solution.
The bactericidal mechanism is an active gene in the oxidizing bacteria, which binds to the amino group to denature the protein. It is characterized by killing most microorganisms, mainly surface disinfection, and unstable properties. The bactericidal effect is greatly affected by environmental conditions, such as sodium hypochlorite, euchloride Net and so on. This type of disinfectant is a medium-effect disinfectant and can be used as a general disinfectant.
The bactericidal mechanism is to change the permeability of the cell membrane, leak the cytoplasm, prevent breathing or denature proteases; sterilization is characterized by its ability to kill bacterial propagules, but has a poor effect on spores, fungi, viruses and tuberculosis bacteria. The effect is good under alkaline and neutral conditions, such as Xin Jie Er, 100 poisons and so on. This type of disinfectant is a low-effect disinfectant and can be used as a general disinfectant.
Highly effective disinfectant
Refers to preparations that can kill all bacterial propagules (including mycobacteria), viruses, fungi and their spores, and also have a certain killing effect on bacterial spores (pathogenic bacillus) and achieve high-level disinfection.
Medium effect disinfectant
Refers to preparations that can kill microorganisms such as mycobacteria, fungi, viruses, and bacterial propagules to achieve disinfection requirements.
Refers to preparations that can kill bacterial propagules and lipophilic viruses and achieve disinfection requirements.
