Compound guanidine disinfectant and preparation method of compound guanidine disinfectant

Abstract

The invention provides a compound guanidine disinfectant, which comprises the following ingredients in percentage by weight: 0.5 to 4.0 percent of guanidine disinfectants, 0.05 to 0.2 percent of low-molecular-weight chitosan, 0.5 to 2.5 percent of high-molecular-weight chitosan, 0.1 to 0.5 percent of Chinese herbal medicine extracts, 0.1 to 1.0 percent of surfactants, 0.1 to 1.0 percent of penetrants, 0.1 to 0.5 percent of skin protectants, 0.1 to 0.5 percent of macromolecule film forming agents and the balance water; and the pH value of the compound guanidine disinfectant is regulated to 7.0 to 7.5 by pH regulating agents. Through the proportional combination of all the ingredients of the compound guanidine disinfectant, a good synergistic effect is achieved; and good sterilization and antibiosis capability is realized on bacterial reproductive bodies, fungi and partial viruses. The invention also provides a preparation method of the compound guanidine disinfectant. The compound disinfectant has the advantages that the preparation process is simple; the operation is convenient; the production cost is low; the scale production is convenient; meanwhile, the property of the disinfectant is stable; and the compound disinfectant is safe and nontoxic and can be easily stored.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a compound guanidine disinfectant for wound disinfection, hemostasis and healing and a preparation method thereof. Background technique [0002] In people's daily home, outdoor, entertainment, and work life, it is inevitable that there will be skin damage and trauma such as abrasions and cuts caused by accidents. The conventional treatment method is to use disinfectants such as alcohol, iodine, and iodophor to sterilize, and then use sterile gauze to bandage and fix the wound. However, this kind of disinfectant is very irritating to the wound, and only has the effect of disinfection and sterilization, and has no effect on the hemostasis and healing of some wounds and wounds. After the disinfection is completed, the wound or wound still needs to be bandaged, otherwise it is easy to cause wound Secondary infection prolongs healing time. Conventional wound dressings use gauze or band-aids, which ...

AI Technical Summary

Problems solved by technology

Both iodine and chlorhexidine have poor water solubility. This patent dissolves iodine through potassium iodide and heats to 50°C to dissolve chlorhexidine acetate. However, the instability of iodine and chlorhexidine in aqueous solution is not clearly resolved in this patent. The problem

At the same time, 12%-15% polyvinyl alcohol is used as a film-forming agent, which makes the disinfectant solution very dense, which is not conducive to coating on the wound, and it is very inconvenient to use. Bring some tightness and discomfort to the wound

[0008] Chinese patent CN101095667A discloses a kind of disinfectant for wound disinfection, which uses isopropanol, chlorhexidine, and distilled water as disinfection components. Isopropanol is obviously irritating to the wound, which is not conducive to the healing of the wound, and will also bring a greater physiological burden to the user
