Bactericide and application thereof

Abstract

The invention discloses a bactericide which comprises an alkyl biguanide bactericide, a polar organic solvent and water. The mass ratio of the alkyl biguanide bactericide to the polar organic solvent to the water is 0.01-2 to 2-50 to 50-98. The pH value of the bactericide ranges from 11.5 to 13.5. The alkyl biguanide bactericide is at least one of polyethyl methyl biguanide, alexidine and hydrochloride of the polyethyl methyl biguanide and the alexidine. The bactericide is high in bacteria killing speed, high in capacity and capable of killing bacterial spores. The bactericide is little in article surface corrosion, irritation and toxicity, and can serve as liquid medicine for disinfectant wet wipes. Surfaces are volatile and dry after the wet wipes are used, and accordingly alkalinity of a solution can be immediately neutralized by carbon dioxide in air. The bactericide can be used for disinfecting the article surfaces and human body surfaces and disinfecting the article surfaces and medical equipment, prevents spreading of microorganisms among people through contact of people and articles, can overcome the defects that existing products are high in human body irritation and low in bactericidal activity, and fills in gaps of international and domestic market.

Description

technical field [0001] The invention relates to a high-efficiency fungicide and its application. Background technique [0002] Disinfectants can be divided into sterilizers, high-efficiency disinfectants, medium-efficiency disinfectants and low-efficiency disinfectants according to their level of action. Sterilizers can kill all microorganisms to meet the sterilization requirements, including formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, hydrogen peroxide, chlorine dioxide and hypochlorous acid. The high-efficiency disinfectant can kill more than 99.9999% of all bacterial propagules (including mycobacteria), viruses, fungi, etc. (that is, the number of remaining bacteria is less than one millionth), and it also has a certain killing effect on bacterial spores . Intermediate-effect disinfectants only kill 99.9999% of bacterial propagules (including mycobacteria), viruses, fungi, etc., but have no killing effect on bacterial spores. Such fungicides include i...

Problems solved by technology

[0005] The advantages of low-efficiency disinfectant quaternary ammonium salts and biguanide fungicides are that they are less corrosive to objects, less polluting to the environment, less irritating to the human body, and less toxic, but their bactericidal effect is also very low, whether used alone or mixed It cannot kill many strains even if used, and it is difficult to cope with the large-scale epidemic viruses that have appeared frequently since the 21st century, such as SARS, bird flu, swine flu, etc.
