TECHNICAL FIELD
[0001] The present application belongs to the technical field of disinfectants, and particularly relates to a surface deodorizing disinfectant, a spray and a preparation method thereof. BACKGROUND
[0002] In recent years, with the synchronous heating of health consciousness and refined life concept, the definition of "disinfection" in the minds of consumers has been rewritten: from the early "visible bacteria count reduction" to "invisible odor molecule zero, fabric fiber non-damage, aroma emotional healing, and mother and infant scene peace" four-in-one. The hot search trend of social e-commerce, third-party consumer reports, and user interviews of head brands all point to the same conclusion: "bacteria killing" has become a threshold-level demand, and "deodorization without damaging clothes, leaving fragrance without irritating, and protecting materials without aging" are the hidden levers that determine repurchase. However, the mainstream technology route still stays in the physical superposition of "chemical bactericidal agent + synthetic fragrance + solvent". Non-alcohol bactericidal ingredients can provide broad-spectrum logarithmic killing, but in real home environment, they frequently expose the side effects of corroding metals, bleaching fabrics, irritating respiratory tracts, or accelerating the cracking of high-molecular materials; traditional 75% ethanol solution, with excellent safety, is listed as the first choice by many pharmacopoeias, but it faces the natural short board of too fast evaporation, too short contact time, and the collapse of the tail of the bactericidal curve under the conditions of home temperature and humidity, and the penetration coefficient of protein-containing biofilms is relatively low, and there is a significant shielding effect on organic dirt such as sebum, saliva, and pet secretions. The deodorization process generally relies on the sensory masking of synthetic fragrances, and low-threshold odor molecules such as hydrogen sulfide, amines, and aldehydes are not truly decomposed, and the mixture of odor and smell after the deodorization process forms a more unacceptable "three-hand odor". At the same time, market products are cut into dozens of SKUs such as fabric-specific, kitchen and bathroom-specific, air-specific, and car decoration-specific due to scene segmentation, and consumers need to prepare different disinfectants for different spaces, different fragrances, and different precautions, and the use cost, storage space, and cognitive burden are rising simultaneously. As a result, an obvious crack appears in the industry: the demand side expects "one bottle of universal, multi-effect, and experience upgrade", while the supply side is trapped in "more components, higher risks, and more detailed scenes", thus the market urgently needs a multifunctional surface spray that integrates efficient disinfection, complete deodorization, safety and environmental protection, and mildness and non-corrosion. SUMMARY
[0003] The first object of the present application is to provide a surface deodorizing disinfectant that has a wide disinfection spectrum, acts quickly, and can decompose odor molecules from the root.
[0004] The second object of the present application is to provide a surface deodorizing disinfectant spray.
[0005] The third object of the present application is to provide a preparation method of a surface deodorizing disinfectant spray.
[0006] To achieve the above object, the technical scheme adopted by the present application is:

[0008] The active component comprises, in parts by mass, glycerol 3-20 parts, ethanol 5-30 parts, acacia extract 1-2 parts, 1-hydroxypiperidine-2-carboxylic acid methyl ester 0.8-1.5 parts, linalool 0.5-5 parts, and biosynthetic nanosilver 10-15 parts.
[0009] Further, the preparation method of the acacia extract is as follows: acacia powder is uniformly stirred in a 90 % volume fraction ethanol aqueous solution, stirred at 40-50 ℃ for 2-5 h, filtered to obtain a primary filtrate and a primary residue; the primary residue is uniformly stirred in a 75 % volume fraction ethanol aqueous solution, stirred at 60-70 ℃ for 2-5 h, filtered to obtain a secondary filtrate and a secondary residue; the primary filtrate and the secondary filtrate are combined, and concentrated and dried to obtain the acacia extract.
[0010] Further, the preparation method of the biosynthetic nanosilver is as follows: cortex fraxini and white willow are mixed and pulverized to obtain a powder, water is added to the powder, ultrasonic extraction is performed, and the supernatant is collected by centrifugation, freeze-dried to obtain an extract, silver nitrate solution is added to the extract to obtain a reaction system, and reaction is performed at 55-60 ℃ for 15-30 min.
[0011] Further, the mass ratio of cortex fraxini to white willow is 3:3-5, and 20-30 mL of water is added per gram of the powder.
[0012] Further, the final concentration of silver nitrate in the reaction system is 1-2 mM, and the final concentration of the extract is 10-30 mg / mL.
[0013] Further, the pH of the reaction system is 7-8.
[0014] Further, the active component comprises, in parts by mass, glycerol 3-10 parts, ethanol 10-30 parts, acacia extract 1-2 parts, 1-hydroxypiperidine-2-carboxylic acid methyl ester 0.8-1.2 parts, linalool 0.5-5 parts, and biosynthetic nanosilver 12-15 parts.
[0015] Further, the deodorization synergist is cyclodextrin, the surfactant is a non-ionic surfactant, the solvent is isopropyl alcohol, and the pH regulator is citric acid or sodium citrate.
[0016] A surface deodorization and disinfection spray agent comprises a propellant and the above-mentioned surface deodorization and disinfection liquid, and the propellant is one or more of propane, n-butane, isobutane and dimethyl ether.
[0017] A preparation method of a surface deodorization and disinfection spray agent, wherein a formula amount of the acacia extract, linalool, biosynthetic nanosilver, deodorization synergist and pH regulator are dissolved in water to obtain a mixed liquid one, and a formula amount of 1-hydroxypiperidine-2-carboxylic acid methyl ester, ethanol, glycerol, surfactant and solvent are uniformly mixed to obtain a mixed liquid two; the mixed liquid two is slowly added to the mixed liquid one, uniformly stirred, filtered, filled into an aerosol can, and then filled with a propellant after valve sealing.
[0018] The present application has the following advantages:
[0019] The surface deodorization and disinfection liquid of the present application does not contain irritating groups and is not irritating to the skin, can remove human body odor, bathroom odor and garbage odor, has a wide application scenario, a wide disinfection spectrum and can decompose odor molecules from the root, avoids "three-hand odor" and avoids the need to purchase different types of disinfection sprays in different scenarios.
[0020] The 1-hydroxypiperidine-2-carboxylic acid methyl ester of the present application has a hydroxyl group and an ester group, and the 1-hydroxypiperidine-2-carboxylic acid methyl ester can act on the microbial membrane interface through hydrogen bonding in the ethanol and glycerol environment, enhance the penetration and damage ability of alcohols to lipids, and thus improve the bactericidal efficiency. The ester structure can be synergized with the acacia extract and linalool to maintain a high bacteriostatic rate while being non-irritating to the skin; the hydroxyl group acts as a donor to form a hydrogen bond with the allylic oxygen atom of linalool; at the same time, the terminal olefin bond of linalool can form a weak C-H···O=C auxiliary hydrogen bond with the ester carbonyl oxygen of 1-hydroxypiperidine-2-carboxylic acid methyl ester to form a two-dimensional zigzag network. The chair conformation of the piperidine ring makes the polar region of 1-hydroxypiperidine-2-carboxylic acid methyl ester and the isopropylene side chain of linalool present "concave-convex complementarity" in size, avoiding steric hindrance and providing geometric conditions for alternate stacking. After the intermolecular synergistic aggregation of 1-hydroxypiperidine-2-carboxylic acid methyl ester-linalool, the hydroxyl group side of 1-hydroxypiperidine-2-carboxylic acid methyl ester produces a hydrogen bond with the sulfhydryl group of hydrogen sulfide, and the ester group side produces a hydrogen bond with the nitrogen hydrogen group of amines, both of which fix odor molecules at the same time, and the adsorption firmness is much better than that of linalool single component. After fixing the odor molecules, the conjugated double bond of linalool provides electrons to the odor, and the ester carbonyl of 1-hydroxypiperidine-2-carboxylic acid methyl ester accepts electrons to form a transient charge transfer complex, which weakens the sulfur hydrogen bond and carbon nitrogen bond in the odor molecule, making it broken and converted into odorless small molecules, realizing complete decomposition rather than fragrance masking.
[0021] The present application uses 1-hydroxypiperidine-2-carboxylic acid methyl ester and biosynthetic nanosilver to synergistically inhibit bacteria, has good bacteriostatic property and a wide bacteriostatic spectrum. DETAILED DESCRIPTION

[0036] Comparative Example 1
[0037] The surface deodorization and disinfection liquid of Comparative Example 1 is basically the same as that of Example 1, and the difference between the surface deodorization and disinfection liquid of Comparative Example 1 and that of Example 1 is that 1-hydroxypiperidine-2-carboxylic acid methyl ester is omitted in Comparative Example 1.
[0038] Comparative Example 2
[0039] The surface deodorization and disinfection liquid of Comparative Example 2 is basically the same as that of Example 1, and the difference between the surface deodorization and disinfection liquid of Comparative Example 2 and that of Example 1 is that biosynthetic nanosilver is omitted in Comparative Example 2.
[0040] Comparative Example 3
[0041] The surface deodorization and disinfection liquid of Comparative Example 3 is basically the same as that of Example 1, and the difference between the surface deodorization and disinfection liquid of Comparative Example 3 and that of Example 1 is that white willow is omitted in Comparative Example 3, and the same mass of cortex fraxini is used instead.
[0042] Comparative Example 4
[0043] The surface deodorizing disinfectant of Comparative Example 4 is substantially the same as that of Example 1, except that the cortex fraxini is omitted in Comparative Example 4 and replaced with the same amount of salix babylonica.
[0044] Comparative Example 5
[0045] The surface deodorizing disinfectant of Comparative Example 5 is substantially the same as that of Example 1, except that the amount of 1-hydroxypiperidine-2-carboxylic acid methyl ester added in Comparative Example 5 is 2 kg.
[0046] Test Example 1
[0047] Bacteriostatic performance test
[0048] According to GB / T 15979-2012 Hygienic Standard for Disposable Hygienic Products Appendix C, the microbial strains are escherichia coli, candida albicans, staphylococcus aureus and pseudomonas aeruginosa, the test conditions are performed according to Appendix C4, and the test liquid is a 1:100 dilution of sample 1. Examples 1-3 and Comparative Examples 1-5 are detected, and the detection results are shown in Table 1.
[0049] Table 1 Bacteriostatic performance test of disinfectants of Examples 1-3 and Comparative Examples 1-5
[0050]
[0051] As can be seen from Table 1, the bacteriostatic performance of Comparative Example 5 is significantly lower than that of Examples 1-3, indicating that the active components can only exert a synergistic bacteriostatic effect under a specific ratio. The bacteriostatic effect of Comparative Examples 1 and 2 is significantly weaker than that of Examples 1-3, confirming that the combination of 1-hydroxypiperidine-2-carboxylic acid methyl ester and biosynthetic silver nanoparticles is the key component for sterilization.
[0052] Test Example 2
[0053] Skin irritation test
[0054] Take 24 guinea pigs (Examples 1-3 and Comparative Examples 1-5, 3 for each group), remove the hair on both sides of the dorsal spine of the guinea pigs with a depilatory 24 h before the test (without damaging the skin), as the test and observation site. The hair removal range: left and right each about 3 cm x 3 cm. 0.5 mL of the original solution of Examples 1-3 and Comparative Examples 1-5 is directly applied to one side of the hairless intact skin with an area of 2.5 cm x 2.5 cm, then covered with a layer of non-irritating plastic film or oil paper, and fixed with non-irritating adhesive tape; the other side of the hairless skin is used as a blank control, and the application time is 4 h. After the test is completed, remove the residual original solution with warm water. Observe the local reaction of the skin at 1 h, 24 h and 48 h after removing the original solution, respectively. The specific content is shown in Table 2.
[0055] According to the "Disinfection Technical Standard" (2002), the skin irritation reaction intensity table is scored in a complete skin irritation test: no erythema-0 points, slight erythema-1 point (barely visible), obvious erythema: -2 points, moderate to severe erythema-3 points, purple red erythema with eschar formation-4 points; no edema-0 points, mild edema-1 point (skin elevation outline clear), moderate edema-2 points (edema elevation about 1 mm), severe edema-3 points (edema elevation more than 1 mm, range expansion), severe edema-4 points (elevation more than 1 mm, extensive range). According to the total score of erythema and edema, the intensity of skin irritation can be evaluated; the specific evaluation criteria may vary depending on different test requirements or institutions, but generally can be divided as follows: no irritation- total score between 0-0.4 points, mild irritation- total score between 0.5-1.9 points, moderate irritation- total score between 2.0-5.9 points, strong irritation- total score between 6.0-8.0 points.
[0056] Table 2 Skin irritation intensity test of disinfectant solutions of Examples 1-3 and Comparative Examples 1-5
[0057]
[0058] The skin irritation results in Table 2 show that Comparative Example 5 has moderate irritation. As can be seen from Tables 1-2, only when the active components are in a specific ratio, can the synergistic bacteriostatic effect be maintained while avoiding skin irritation.
[0059] Test Example 3
[0060] Deodorization test
[0061] Deodorization tests were performed on odor substances using the surface deodorizing disinfectant solutions of Examples 1-3 and Comparative Examples 1-5. The specific method steps were: at a distance of 10-20 cm from the odor substance, press the nozzle to spray uniformly 3-5 times, with a single spraying amount of 0.10-0.12 g. After spraying, the removal effect on the odor substances was recorded after 30 min, and the test results are shown in Table 3. The odor intensity was scored: no odor-1, slightly odor-2, odor but not irritating-3, irritating odor-4, strong irritating odor-5, unbearable odor-6.
[0062] Table 3 Deodorization test of disinfectant solutions of Examples 1-3 and Comparative Examples 1-5
[0063]
[0064] As can be seen from Table 3, the deodorization effect of Examples 1-3 is significantly better than that of Comparative Examples 1-5. The deodorization effect of Comparative Example 1 is the weakest, indicating that 1-hydroxypiperidine-2-carboxylic acid methyl ester can effectively remove odors from the human body, bathroom, and garbage by cooperating with other substances in the active component.
