Method for preparing washing-free polyhexamethylene guanidine hydrochloride disinfectant

Abstract

The invention belongs to a preparation method of a washing-free polyhexamethylene guanidine hydrochloride disinfectant. The preparation method is as follows: dissolving 0.5-6 g of polyhexamethylene guanidine hydrochloride in 92 g of medical deionized water, adding 1.5-3 g of coconut oil amide betaine (CAB) and 0.8-1.5 g of alkyl glycoside (APG), adjusting pH value of the solution to 4.5-5.0 by using sodium hydroxide, adding the above raw materials into a stirring tank, uniformly mixing, and sub-packaging. The disinfectant has broad sterilization spectrum, quick effect and long lasting sterilization capacity, is safe, nontoxic and environmentally-friendly, has a strong killing effect on Brucella, Escherichia coli, Staphylococcus aureus, Candida albicans and the like, has good stability, hasa validity period of up to two years, has the advantages of easy smearing, rapid penetration, rapid volatilization, no coloring, easy cleaning and the like, can be used for skin and wound disinfection, hand disinfection, air disinfection, gynecology and urological disinfection, drinking water disinfection, etc., and is a novel and ideal convenient disinfectant.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to a preparation method of a wash-free polyhexamethyleneguanidine hydrochloride disinfectant. Background technique [0002] In public places where people are relatively concentrated and crowded, such as hospitals, airports, stations, restaurants, offices, etc., it is very easy to cause the spread of bacteria and viruses, resulting in cross-infection of the public. Hospitals, in particular, are not only places where diseases are treated, but also places where diseases may spread. During the transmission of these bacteria and viruses, especially due to the touch of the public's hands, such as the doctor's palpation of the patient, railings, door handles, handrails in the car, etc., is an important factor causing public cross-infection. Combined with the enlightenment given by the epidemic of SARS, we realize the importance of large-scale disease prevention in public places. In this case...
