preparation example Construction

[0031] The present invention also provides a preparation method of the hydrogen peroxide disinfectant according to the above technical solution, which includes: mixing the light and heat stabilizer, the metal ion chelating agent, the hydrogen peroxide solution and water, adding the pH value regulator, and then aging, Obtain the hydrogen peroxide disinfectant.

[0032] The present invention does not specifically limit the equipment used in the preparation process, and the equipment well known to those skilled in the art can be used. In the embodiment of the present invention, it is preferably a beaker.

[0033] In the present invention, a light-heat stabilizer, a metal ion chelating agent, a hydrogen peroxide solution and water are mixed to obtain a mixed solution.

[0034] The present invention has no special requirements on the mass concentration of the hydrogen peroxide solution, and the mass content of the hydrogen peroxide in the hydrogen peroxide disinfection solution can reach ...

Embodiment 1

[0042] In terms of mass content, the composition of hydrogen peroxide disinfectant is: glucose 10%, maltitol 10%, sodium citrate 2%, hydrogen peroxide 3%, lactic acid 3%, and purified water 69%.

[0043] figure 1 The flow chart for preparing hydrogen peroxide disinfectant in this embodiment, such as figure 1 As shown, the preparation method of hydrogen peroxide disinfectant in this embodiment is as follows: add 69g purified water in a beaker, add 10g glucose and 10g maltitol under 200r / min stirring conditions for 5min, then add 2g sodium citrate and stir for 5min, Add 6g of 50% hydrogen peroxide solution and stir for 5 minutes, then add 3g of lactic acid to adjust the pH to 2.94, stop stirring after 5 minutes of stirring, and age at 25°C for 30 minutes.

Embodiment 2

[0045] In terms of mass content, the composition of hydrogen peroxide disinfectant is: 2% sodium polyacrylate, 1% disodium edetate, 1% sodium citrate, 5% glucose, 10% mannitol, hydrogen peroxide 3 %, citric acid 5%, purified water 70%.

[0046] The preparation method of hydrogen peroxide disinfectant in this embodiment is: add 70g of purified water in a beaker, add 2g of sodium polyacrylate under 200r / min stirring conditions, heat to 60°C to dissolve, then drop to 25°C, add 5g glucose and 10g Stir mannitol for 5min, then add 1g disodium ethylenediaminetetraacetic acid and 1g sodium citrate and stir for 5min, add 6g 50% hydrogen peroxide solution and stir for 5min, add 5g citric acid to adjust the pH to 2.71, stir for 5min and stop stirring. Aging at 25°C for 30 minutes.

Abstract

The invention provides a hydrogen peroxide disinfectant and a preparation method thereof, and belongs to the technical field of disinfectants. The hydrogen peroxide disinfectant provided by the invention comprises 10-30 wt% of a photo-thermal stabilizer, 1-5 wt% of a metal ion chelating agent, 3-8 wt% of a pH value regulator, 2.5-3.5 wt% of hydrogen peroxide and the balance of water, the metal ionchelating agent can complex metal ions in the solution, reduces the decomposition effect of the metal ions on the hydrogen peroxide, and still has excellent complexing ability under acidic conditions; the photo-thermal stabilizer can reduce decomposition of the hydrogen peroxide by light and heat, so that the hydrogen peroxide disinfectant shows better stability under higher temperature and illumination; the pH value regulator is used for regulating the pH value of the system, the stability of the hydrogen peroxide disinfectant is further improved, and after the hydrogen peroxide disinfectantis stored in an oven at 37 DEG C for 90 days, the reduction rate of the content of hydrogen peroxide is less than 5%, so that the requirement on the stability of the disinfectant in Technical Specification for Disinfection (2002 edition) is met.

Description

Technical field [0001] The invention relates to the technical field of disinfectants, in particular to a hydrogen peroxide disinfectant and a preparation method thereof. Background technique [0002] Hydrogen peroxide disinfectant is a commonly used medical disinfectant. Hydrogen peroxide has a strong oxidizing ability and a broad sterilization spectrum. It can effectively kill various bacterial propagules, fungi and viruses. It is often used for purulent wound treatment and otitis media. And oral cleaning. However, most hydrogen peroxide disinfectants have the problem of poor stability, which affects the appearance and disinfection effect of the product. [0003] In the prior art, in order to improve the stability of hydrogen peroxide, physical methods such as adding sodium phosphate, sodium polyphosphate, sodium silicate, or using opaque bottles and storing in a cool place are usually adopted. However, sodium phosphate, sodium polyphosphate, and sodium silicate contain phosphor...
