Problems solved by technology

The amine salts contained in the disinfectant, such as alkyl dimethyl benzyl ammonium chloride and alkyl dimethyl benzyl ammonium chloride, have serious irritation to human eyes and skin, and the disinfectant It also contains aldehyde components such as glutaraldehyde, citral, jasmonal, and myristaldehyde. Some of these aldehydes have serious irritation to human eyes and skin, and some are extremely unstable. down to use
[0005] And this disinfectant still has problems such as heavy smell, corrosiveness, effective time of sterilization and disinfection (in hours) etc.
Therefore, it is still not suitable for public use

Embodiment 1

[0046] Prepared according to the following components: 20% polyhexamethylene biguanide PHMB thickener hydroxypropyl methylcellulose 0.5%; chelating agent EDTA 0.1%; surfactant C 13 Alcohol 7EO 0.1%, water 94.3%.

[0047] Preparation method:

[0048] Add 40-50% of 65-75 DEG C water into chelating agent EDTA and thickener hydroxypropyl methylcellulose and stir evenly. When cooling to 20-30°C, add polyhexamethylene biguanide PHMB and surfactant C 13 Stir alcohol 7EO, essence and remaining deionized water evenly. Let it stand and filter to obtain a transparent and uniform liquid.

[0049] Under EN1040:1997, in the test against Pseudomonas aeruginosa, compared with PHMB alone, PHMB combined with chelating agent showed a significant improvement in bactericidal activity, about 30-300 times higher. See Table 1.

Embodiment 2

[0051] Prepared according to the following components: 20% polyhexamethylene biguanide PHMB 15%; thickener hydroxyethyl cellulose 3.%; chelating agent glutamic acid tetrasodium acetoacetate 3%; surfactant sorbose Alcohol Monolaurate 20EO 3%, Water 76%.

[0052] Preparation method: with embodiment 1.

[0053] The transparent uniform liquid can be sprayed with common spraying equipment (such as household sprayer) to form a layer of transparent film.

Embodiment 3

[0055] Prepare according to the following components

[0056] 20% polyhexamethylene biguanide PHMB 20%; hydroxypropyl cellulose 3%; chelating agent ethylenediamine disuccinate disodium salt 1.5%; surfactant ethylenediamine triacetate cocoalkylacetamide 1 %, water 74.5%.

[0057] Preparation method: with embodiment 1.

[0058] After the above solution was kept in the dark for a period of 12 months, the active ingredient concentration decreased from the initial 5% to about 4.2%.

According to the technical scheme provided by the invention, the spray having the function of disinfection and sterilization includes the following componments: 20% PHMB: 0.01-25; thickening agent 0.1-5.0; chelating agent 0.025-6; surface active agent: 0.025-6; water: 58-99.84, wherein percentage by weight is the unit. The spray having the function of disinfection and sterilization is characterized by long working life and convenient cleaning.

Description

technical field [0001] The invention relates to the field of disinfectant, in particular to a spray with disinfection and sterilization functions, which is suitable for disinfection and sterilization in public places. technical background [0002] Air disinfection and sterilization in public places is an important means to improve health and safety. The fungicides used in public places must not only meet the hygienic requirements for timely disinfection, but also need to meet a certain action time limit and have no harmful effects on the human body. There are no adverse effects on site implementation. [0003] The main means of air disinfection and sterilization in the environment of public places is to spray disinfectant at the ventilation (changing) tuyere or directly in the environment, and ultraviolet rays are also used to treat the convective air passing through the ventilation opening. Wherein the most direct and effective method of disinfection and sterilization is s...
