With the rapid development of animal husbandry, infectious diseases are becoming more and more harmful to people. Many people choose to use disinfectants, which can kill various pathogens, reduce environmental pollution, and cut off the route of transmission, playing an important role. Is the disinfectant harmful to the human body ? However, many users do not understand, there is a lot of blindness in use, there are many misunderstandings, let's take a look at the relevant knowledge below!
Oxidation: The bactericidal mechanism is to release the new ecological atomic oxygen and the active group in the oxidizing bacteria; the bactericidal feature is fast and strong, which can kill all microorganisms, including bacterial spores and viruses. Mainly surface disinfection, such as chlorine dioxide, hydrogen peroxide, ozone, sodium hypochlorite, etc., such disinfectants are sterilizing agents.
Aldehyde disinfectants: including formaldehyde and glutaraldehyde. The principle of such disinfection is that an active alkylating agent acts on the amino, carboxyl, hydroxyl and sulfhydryl groups in the microbial protein, thereby destroying the protein molecules and causing the microorganisms to die. Both formaldehyde and glutaraldehyde can kill various microorganisms. Because they have stimulating and curing effects on human skin and mucous membranes, and can make people sensitized, they can not be used for disinfection of air, utensils, etc., and are generally only used in hospitals. Disinfect or sterilize medical devices, and disinfected or sterilized items must be rinsed with sterile water before use.
Alcohol disinfectants: The most commonly used are ethanol and isopropanol, which can coagulate proteins and cause microbial death. It is a medium-acting disinfectant that kills bacterial propagules and destroys most lipophilic viruses, such as herpes simplex virus, type B. Hepatitis virus, human immunodeficiency virus, etc. The microbial action of alcohols can also be affected by organic matter, and because of the volatilization, soaking or repeated wiping should be used to ensure the action time. Alcohols are often used as solvents for certain disinfectants, and they have synergistic effects. The usual concentration is 75%. Is the disinfectant harmful to the human body ? According to foreign reports: 80% ethanol has a good inactivation effect on the virus. In recent years, there are many complex alcohol disinfectants at home and abroad, and these products are mostly used for hand skin disinfection.
Iodine-containing disinfectant: including iodine and iodophor, can kill bacterial propagules, fungi and some viruses, can be used for skin and mucous membrane disinfection, hospitals are often used for surgical hand washing.
Alkali, salt: The sterilization mechanism is to denature, precipitate or dissolve the protein; the sterilization is characterized by killing the bacterial propagule, killing the bacteria spores, viruses and some hard-to-kill microorganisms. Strong bactericidal effect, strong corrosive, such as sodium hydroxide, calcium oxide, salt (non-corrosive). Generally only as a preventive disinfectant and sterile wash solution.
Do you know about the problem that disinfectant is harmful to the human body? It is necessary to remind everyone that the disinfectant can not be mixed and used in strict accordance with the instructions.
