Embodiment 1

[0015] Prepare 500ml of acidic electrolyzed water (available chlorine content 200mg / L), at room temperature, after pH adjustment, add 5g of PVP K30 to the acidic electrolyzed water. The mixture is then diluted with 3 times the amount of water to obtain the application concentration.

[0016] One week after the mixture was balanced and stable, 10 g of modified chitosan was added to the mixture, stirred and allowed to stand for 2 days.

[0017] The mixture obtained in this way is suitable for the treatment and disinfection of skin wounds. For the preparation of gels, customary thickeners such as acrylates can be added.

Embodiment 2

[0019] A potent germicidal disinfectant is produced as follows:

[0020] Prepare 500ml acidic electrolyzed water (available chlorine content 200mg / L), add 3g PVP K30 at room temperature. The mixture was then stirred until a stable equilibrium was obtained, and then 5 g of modified chitosan was added. After further stirring, 500 ml of deionized water was added, followed by an additional 3 g of PVP K30. It was further diluted with 500ml of deionized water, and then 10g of modified chitosan was added to obtain the final reagent.

Abstract

The invention relates to a multipurpose biological safety disinfectant. The disinfectant contains acidic electrolyzed water, polyvinylpyrrolidone and modified chitosan. The acidic electrolyzed water is high in hypochlorous acid molecule content, has sterilization and disinfection effects, and has an efficient broad-spectrum antibacterial effect. The polyvinylpyrrolidone is used as a stabilizer, sothat the stability of the disinfectant can be improved, and the validity period of the disinfectant is prolonged to 18 months. The modified chitosan serving as an antibacterial agent can form a water-based film on the surface of an object, so that the antibacterial time of the disinfectant is prolonged. The biological safety disinfectant is slightly acidic and can be used for surface disinfection, and degradation products are safe and non-toxic.

Description

technical field [0001] The invention belongs to the field of disinfectant manufacture, and in particular relates to a multipurpose biosafety disinfectant. Background technique [0002] Inorganic chlorine disinfectant is a widely used disinfection product in public places and medical and health institutions because of its high efficiency in killing microorganisms (especially viruses), widespread sterilization, and relative safety. Residual chlorine is harmful to the human body and other characteristics, so that its scope of use is limited. Therefore, while traditional disinfectants kill environmental microorganisms, they also have adverse effects on the human body, making it difficult to guarantee their safety. [0003] Electrolysis of water refers to electrolysis of low-concentration electrolyte solutions, such as sodium chloride solution, dilute hydrochloric acid solution, or a mixture of the two, in an electrolytic cell to make the pH value and oxidation-reduction potenti...
