Description

Technical Field

[0001] This invention relates to the field of detergent technology, specifically to a multifunctional dishwashing liquid and its preparation method. Background Technology

[0002] As a daily necessity, dishwashing liquid's core function is to remove grease, food residue, and other stains from tableware. Currently, most mainstream dishwashing liquids on the market rely primarily on the emulsifying, solubilizing, and wetting effects of surfactants for their cleaning power. However, the function of traditional dishwashing liquids is becoming increasingly limited and cannot meet the growing and diversified needs of consumers.

[0003] First, traditional dishwashing liquids are significantly inadequate in dealing with environmental pollutants. Conventional dishwashing liquid formulations are designed only for organic oil stains; their ingredients lack the ability to adsorb or complex heavy metal ions, thus failing to effectively remove inorganic pollutants.

[0004] Secondly, traditional dishwashing liquids offer limited hygiene protection. The kitchen environment is humid and warm, making it highly susceptible to the growth of bacteria, mold, and other microorganisms. Used tableware, especially that that has come into contact with raw food, can become a medium for cross-contamination. Although some products add chemically synthesized bactericides to achieve antibacterial properties, these can lead to problems such as drug resistance, chemical residues, skin irritation, and environmental pollution. Most ordinary dishwashing liquids do not have long-lasting antibacterial capabilities; if not thoroughly rinsed or dried after washing, the residual moisture and trace organic matter may actually accelerate microbial growth. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multifunctional dishwashing liquid and its preparation method. Through the scientific compounding and synergistic effect of multiple components, it integrates multiple functions such as high-efficiency stain removal, heavy metal adsorption, long-lasting antibacterial effect, and green safety, providing a comprehensive and multi-layered cleaning and protection solution, effectively solving the drawbacks of traditional dishwashing liquids with only one function.

[0006] To achieve this objective, the present invention adopts the following technical solution: On one hand, the present invention provides a multifunctional dishwashing liquid, comprising the following components by weight: 3-6 parts sodium citrate; 8-12 parts of surfactant; Antibacterial agent 0.3-0.5 parts; 3-5 parts of cyclodextrin; 3-6 parts bentonite; 3-6 parts diatomaceous earth; 5-8 parts of NAT-K zeolite; 2-5 parts of KASH zeolite; 70-90 parts deionized water.

[0007] As a preferred option for a multi-purpose dishwashing liquid, it comprises the following components by weight: 4 parts sodium citrate; 8 parts surfactant; 0.5 parts antibacterial agent; 3 parts cyclodextrin; 3.5 parts bentonite; 3.5 parts diatomaceous earth; 5 parts NAT-K zeolite; 2.5 parts of KASH zeolite; 70 parts of deionized water.

[0008] As a preferred embodiment of a multifunctional dishwashing liquid, the surfactant is cocoyl glucoside.

[0009] As a preferred option for a multifunctional dishwashing liquid, the antibacterial agent is tea tree oil.

[0010] On the other hand, the present invention provides a method for preparing a multifunctional detergent, comprising the following steps: S1. Preparation of NAT-K zeolite and KASH-type zeolite materials; S2. Bentonite, diatomaceous earth and cyclodextrin were pre-dispersed separately. S3. Add deionized water to the reaction vessel and heat to 50°C. Then add cocoyl glucoside and sodium citrate in sequence, and stir at 1000-1500 rpm for 10-15 minutes until completely dissolved to form a basic cleaning solution. S4. Slowly add bentonite suspension, diatomaceous earth dispersion and cyclodextrin aqueous solution to the reactor, and stir at 1500-2000 rpm for 10 min to fully mix with the basic cleaning solution; S5. Add tea tree oil to the reactor and continue stirring for 5 minutes. Finally, add NAT-K zeolite and KASH zeolite, increase the speed to 2000-2500 rpm and stir for 30 minutes. Monitor the viscosity of the system with a viscometer until it stabilizes at 300-500 mPa•s to obtain a uniform multifunctional detergent.

[0011] As a preferred method for preparing multifunctional dishwashing liquid, the specific preparation steps of NAT-K zeolite in step S1 are as follows: Lignite bottom ash was ground to a particle size of 6.6 μm, and iron compounds were removed by magnetic separation. It was then mixed with a 7 mol / L KOH solution at a liquid-to-solid ratio of 8:1 and refluxed at 100-110 °C for 24 h. After the reaction, the mixture was filtered and washed until the pH of the filtrate was 10, and then dried at 110 °C for 24 h to obtain NAT-K zeolite.

[0012] As a preferred method for preparing multifunctional detergent, the specific preparation steps of KASH-type zeolite in step S1 are as follows: Lignite bottom ash was ground to a particle size of 3.0 μm, and iron compounds were removed by magnetic separation. It was then mixed with a 9 mol / L KOH solution at a liquid-to-solid ratio of 8:1 and refluxed at 100-110℃ for 24 h. After the reaction was completed, the mixture was filtered and washed until the pH of the filtrate was 10, and then dried at 110℃ for 24 h to obtain KASH-type zeolite.

[0013] As a preferred embodiment of the preparation method for multifunctional detergent, the pre-dispersion treatment of bentonite in step S2 is as follows: Weigh out the required amount of bentonite according to the formula, mix it with deionized water at a mass ratio of 1:5-1:8, pour it into a high-speed disperser, set the speed to 5000-8000 rpm and the temperature to 45-55℃, and disperse continuously for 15-20 minutes. During this period, monitor the particle size distribution in real time with a laser particle size analyzer to ensure that the bentonite particles are uniform in size, stable at 1-5μm, and without any visible agglomerates, thus forming a uniform bentonite suspension.

[0014] As a preferred embodiment of the preparation method for multifunctional detergent, the pre-dispersion treatment of diatomaceous earth in step S2 is as follows: Weigh out the required amount of diatomaceous earth, dry it at 100-110℃ for 1 hour to remove adsorbed water, and after cooling, mix it with deionized water at a mass ratio of diatomaceous earth:deionized water = 1:6-1:10. Pour the mixture into a high-speed disperser, and simultaneously add 0.1%-0.3% of a dispersing agent to reduce the interparticle forces. Set the speed to 6000-8500 rpm and the temperature to 50-60℃, and continue dispersing for 18-25 minutes. During this period, observe the mixture with a scanning electron microscope to ensure that the porous structure of the diatomaceous earth is not destroyed and that it is in a monodisperse state in water, forming a stable diatomaceous earth dispersion.

[0015] As a preferred embodiment of the preparation method for multifunctional detergent, the pre-dispersion treatment of cyclodextrin in step S2 is as follows: Weigh out the required amount of cyclodextrin and mix it with deionized water at a mass ratio of 1:10 to 1:15. Pour the mixture into a constant temperature water bath stirring tank, set the speed to 800-1200 rpm and the temperature to 50-55℃, and stir continuously for 20-30 minutes. During this period, measure the transmittance of the solution using a UV spectrophotometer. When the transmittance is stable above 95%, it indicates that the cyclodextrin is completely dissolved and there are no undissolved particles, forming a clear cyclodextrin aqueous solution.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This invention introduces NAT-K zeolite and KASH zeolite into dishwashing liquid. These zeolites with regular pore structures can effectively adsorb heavy metal ions such as lead, cadmium, and mercury from water and tableware surfaces, and fix them through ion exchange, thereby effectively preventing heavy metals from entering the human body through tableware. This solves the problem that traditional products cannot cope with inorganic heavy metal pollution. Bentonite and diatomaceous earth, as natural adsorbents, further enhance the total adsorption capacity of the formula for oils and polar pigments. With the synergistic effect of zeolite, they can adsorb and purify organic and inorganic pollutants in an all-round way.

[0017] (2) This invention uses tea tree oil as a natural antibacterial agent and encapsulates it at the molecular level with cyclodextrin. The "molecular capsule" effect of cyclodextrin protects the effective components of tea tree oil, prevents its oxidation and excessive volatilization, and ensures the stability of the product. On the other hand, it achieves slow and controllable release of tea tree oil during use, thereby providing a long-lasting antibacterial and bacteriostatic effect. It can effectively inhibit common kitchen microorganisms such as Escherichia coli and Staphylococcus aureus, and prevent secondary contamination and cross-infection of tableware.

[0018] (3) The diatomaceous earth and bentonite used in this invention form a synergistic effect with cocoa oil glucoside. First, through the friction and adsorption of physical cleaning components such as diatomaceous earth and bentonite, the dirt film becomes thinner and looser, thereby giving full play to the penetration and emulsification effect of cocoa oil glucoside, achieving a doubling of cleaning efficiency, and the cleaning effect on stubborn oil stains is significantly better than that of traditional products.

Weigh each glass slide, and use the prepared clips to clamp each slide above the line of the known-weight slide. Then hang it on the drying rack and place the drying rack in an enamel tray to prepare for coating.

[0061] 1.1.3 Slide contamination Take an appropriate amount of the prepared mixed oil and place it in a constant temperature water bath to maintain the oil temperature at (50±2)℃. Remove the glass slides one by one from the drying rack along with the clamps. Holding the clamps, slowly immerse the glass slides in the oil at a temperature of (50±2)℃ down to 10mm below the top edge, and then slowly remove them. Repeat this process 2 to 3 times. After the last coating, when the dripping speed of the oil slows down, hang the coated slides back on the original drying rack. Prepare the coated slides in sequence. After the oil on the glass slides solidifies, wipe the excess oil on the bottom edge and sides of the slides 5mm below the bottom edge with filter paper or degreased cotton, and then wipe them clean with degreased cotton soaked in anhydrous ethanol or petroleum ether using tweezers. Let them air dry for 3 hours under the environmental conditions required for this experiment. Transfer the dried coated slides to the weighing rack and accurately weigh the mass of each coated glass slide using an analytical balance. The amount of oil on each slide should be controlled at (0.13±0.02)g. Each group consists of 4 slides, and the amount of oil on each group should be controlled at (0.50±0.05)g.

[0062] 1.1.4 Test Procedure Conduct the experiment according to the following steps.

[0063] Stain remover settings: washing temperature 30℃, rotation speed 160r / min, washing time 3 min.

[0064] Sample preparation: Weigh 4.0g of the sample to be tested and dissolve it in 2000mL of 250mg / L hard water, shake well and set aside.

[0065] Insert the prepared soiled sheets into the washing rack in groups of four for washing.

[0066] Measure 800 mL of the test solution and place it into the washing tank of the vertical cleaning machine, with each pair of washing tanks corresponding to a parallel sample. When the temperature of the test solution reaches 30℃, quickly place the stained sheets of known mass along with the washing racks into the washing tanks. Start the soaking time when the last washing rack is in place. Install the stirrer, and after soaking for 1 minute, start the cleaning machine to begin washing. After 3 minutes, the cleaning machine will automatically stop. Quickly remove the stirrer and take out the washing rack. Hang the washed stained sheets one by one on the drying rack and let them air dry for 2 hours under the environmental conditions required for this experiment before transferring them to the weighing rack for weighing. The experimental results are for reference. Figure 1 and Figure 2.

[0067] Parallel tests were conducted using standard dishwashing detergents on the same machine.

[0068] 2. Detergent power test data 2.1 Calculation of detergency In the formula, w is the degreasing rate; m0 is the mass of the slide before coating (g); m1 is the mass of the slide after coating (g); and m2 is the mass of the stained slide after washing (g).

[0069] 2.2 Evaluation of detergency The arithmetic mean of the ratio of the oil removal rate of the sample to that of the standard dishwashing detergent is used as the test result. When the ratio of the oil removal rate is greater than 1.05, it is judged that the detergency is greater than that of the standard dishwashing detergent; when the ratio of the oil removal rate is less than 0.95, it is judged that the detergency is less than that of the standard dishwashing detergent; when the ratio of the oil removal rate is greater than or equal to 0.95 and less than or equal to 1.05, it is judged that the detergency is equal to that of the standard dishwashing detergent.

[0070] 2.3 Experimental Data Table 1: Detergency test data of the detergents prepared in the examples and comparative examples 2.4 Experimental Conclusions The detergency test data showed that the oil removal rate of the multifunctional dishwashing liquid in Example 1 was 1.99 times that of the standard dishwashing detergent in Comparative Example 1, thus proving that Example 1 has a strong detergency effect. The detergency of dishwashing liquid in Comparative Example 2 (without zeolite) and Comparative Example 3 (with a single zeolite system) both showed a slight decrease, indicating that NAT-K zeolite and KASH-type zeolite have a weak synergistic effect on basic detergency. While the dishwashing liquid in Comparative Example 5, which lacks a natural adsorption / abrasive system, has a stronger detergency than standard dishwashing detergent, its detergency is weaker than that of Example 1. This is mainly due to the absence of diatomaceous earth and bentonite. The diatomaceous earth and bentonite in Example 1 provide essential physical friction and adsorption, which can thin and loosen the dirt film, thereby fully utilizing the penetration and emulsification effects of cocoyl glucoside. The two produce a synergistic effect, achieving a doubling of detergency efficiency and significantly outperforming traditional products in cleaning stubborn oil stains.

[0071] Metal ions (with lead ions Pb) 2+ Removal effect experiment (using representative indicators): 1. Experimental Procedure 1.1 Preparation of contaminated glass slides 1.1.1 Accurately weigh 0.150 g of simulated heavy metal pollutant (lead nitrate) using an electronic balance, dissolve it in 100 mL of deionized water, and prepare a 1500 μg / mL Pb solution. 2+ Contaminated liquid.

[0072] 1.1.2 Use a pipette to draw 0.2 mL of contaminated liquid and spread it evenly on the surface of each glass slide (coating area 10 cm²). 2 Place in a 60℃ oven to dry for 30 minutes, then cool and set aside.

[0073] 1.1.3 Blank control: Take another identical glass slide, apply only deionized water, and dry under the same conditions.

[0074] 1.2 Sample Pretreatment (Dry Ashing Method) 1.2.1 Take the contaminated glass slide, place it in a 50mL crucible with tweezers, and char it over a low flame until no smoke is produced.

[0075] 1.2.2 Add 2 mL each of hydrochloric acid and nitric acid, heat until the white fumes disappear, and transfer to a 550℃ resistance furnace for 4 hours to ashed.

[0076] 1.2.3 After cooling, add 2 mL of 6 mol / L hydrochloric acid to wet the residue, evaporate to dryness in a water bath, dissolve in 10 mL of deionized water, transfer to a 50 mL volumetric flask and make up to volume, label as "contaminated original solution".

[0077] 1.3 Washing procedure (parallel samples are washed simultaneously) 1.3.1 Take 4 contaminated glass slides from each group, put them in a 250mL beaker, and add 100mL of 1% sample solution (at a constant temperature of 25℃).

[0078] 1.3.2 Stir and wash with a magnetic stirrer for 10 minutes (300 r / min), then remove the slide and rinse it three times with deionized water (10 s each time).

[0079] 1.3.3 Collect the washing solution into a 50mL volumetric flask, dilute to volume, and label it as "washing solution"; collect the rinsing solution separately for later use.

[0080] 1.4 Preparation of Reagent Blank Take 100 mL of deionized water, stir for 10 min under the same conditions as in step 1.3, collect the solution and process it according to the sample pretreatment method to obtain the reagent blank solution.

[0081] 1.5 Colorimetric Reaction 1.5.1 Take three 50mL Nessler tubes and label them A (standard tube), B (sample tube), and C (blank tube).

[0082] 1.5.2 Tube A: Add 1.0 mL of 10 ug / mL lead standard working solution, add water to 25 mL, add 1 drop of phenolphthalein indicator, adjust to a faint pink color with ammonia, then remove the red color with 1 mol / L hydrochloric acid, and add 2 mL of glacial acetic acid (pH 3.5-4.0).

[0083] 1.5.3 Tube B: Add 10 mL of “washing solution”, adjust the pH according to the steps in tube A, and add glacial acetic acid.

[0084] 1.5.4 C tube: Add 10 mL of reagent blank solution, adjust the pH under the same conditions, and add glacial acetic acid.

[0085] 1.5.5 Add 2 drops of sodium sulfide solution to each of the three tubes, shake well, and then place them in a 30°C water bath for 5 minutes to react.

[0086] 1.6 Absorbance Measurement 1.6.1 Using tube C as a blank control, adjust the wavelength of the spectrophotometer to 510nm and calibrate the zero point.

[0087] 1.6.2 Measure the absorbance of tube A and tube B sequentially, and measure each tube three times in parallel, and record the average value (RSD≤1%).

[0088] 1.7 Parallel Sample Replication Replace each group with four new contaminated slides and repeat steps 1.3-1.6, then calculate the relative average deviation.

[0089] 1.8 Blank Validation Take an uncontaminated blank glass slide, and complete the washing and testing steps described above to confirm that there is no heavy metal interference.

[0090] 2. Experimental data on metal ion removal 2.1 Calculation of heavy metal residue In the formula, C0 is the concentration of the standard solution (30 μg / mL); A S A0 represents the absorbance of the sample; A0 represents the absorbance of the standard solution.

[0091] 2.2 Calculation of Heavy Metal Removal Rate In the formula, C1 is the concentration of the original contaminant solution; C2 is the concentration of the solution after washing.

[0092] 2.3 Experimental Data Table 2: Experimental data on the metal ion removal effect of the detergents prepared in the examples and comparative examples. 2.4 Experimental Conclusions Experimental data on the removal effect of metal ions showed that the multifunctional dishwashing liquid of Example 1 achieved a heavy metal removal rate of 77.7%, which was significantly better than the standard dishwashing liquid of Comparative Example 1. This proves that the multifunctional dishwashing liquid of Example 1 can effectively remove heavy metal ions from the surface of tableware. The dishwashing liquid in Comparative Example 2 without zeolite system was basically the same as the standard dishwashing liquid in Comparative Example 1 in terms of metal ion removal effect. This proves that the excellent metal ion removal effect of Example 1 is mainly due to NAT-K zeolite and KASH zeolite. These zeolites with regular pore structure can effectively adsorb heavy metal ions such as lead, cadmium, and mercury on the surface of water and tableware, and fix them through ion exchange, thereby effectively blocking the pathway of heavy metals to enter the human body through tableware, solving the pain point that traditional products cannot deal with inorganic heavy metal pollution. The dishwashing liquid of Comparative Example 3, consisting of a single zeolite system, also outperformed the standard dishwashing liquid of Comparative Example 1 in removing metal ions, but was slightly inferior to the multi-functional dishwashing liquid of Example 1. This demonstrates that the combination of the two zeolites produced a positive synergistic adsorption effect, outperforming either single component. This is mainly because NAT-K zeolite and KASH-type zeolites have distinctly different crystal structures. NAT-K zeolite possesses a relatively small effective pore size, making it more suitable for allowing metal ions with smaller hydration radii or smaller ionic radii (such as Pb). 2+ Cd 2+ Zn 2+ ) enters its pores and comes into contact with more ion exchange sites. For heavy metal ions with larger ionic radii (such as Hg), 2+ Even though their hydration radii may vary depending on the degree of hydration, they have significant steric hindrance to entering the pores of mordenite zeolite, resulting in lower efficiency. Therefore, NAT-K zeolite primarily captures relatively small heavy metal ions. KASH-type zeolites, on the other hand, possess larger, open pores. Larger pore sizes mean that ions need to shed less hydration before entering the pores, or can enter in a form closer to their hydrated ion form. This provides unobstructed passage for larger molecules and ions and offers a large internal surface area, thus exhibiting a natural affinity for large-radius ions. Example 1 demonstrates that the combination of two zeolites with different pore sizes produces a synergistic effect, covering almost all common harmful heavy metal ions from small to large radii. This combination ensures that the product efficiently removes multiple heavy metals regardless of changes in water quality or pollution sources, with an overall adsorption effect significantly superior to using any single zeolite.

[0100] 1.1.3 Verify purity and morphology Observe the colony morphology, size, color, and transparency on the plates to ensure consistency with the description of the standard strain. If necessary, perform Gram staining and microscopic examination to confirm the staining characteristics, morphology, and purity of the bacteria, ensuring no contamination.

[0101] 1.1.4 Working strain Select a typical single colony from a freshly activated plate and perform a second subculture to ensure the viability and purity of the strain. The strain obtained after the second subculture is the working strain used in the experiment that day.

[0102] 1.1.5 Prepare bacterial suspension Using a sterile inoculation loop, pick an appropriate amount of typical colonies from the working strain plate and inoculate them into test tubes containing 5.0 mL of tryptone soybean broth (TSB, suitable for Escherichia coli and Staphylococcus aureus) or Sabouraud dextrose liquid medium (suitable for Candida albicans).

[0103] Escherichia coli and Staphylococcus aureus: Incubate at 36±1℃ with shaking for 18-24 hours.

[0104] Candida albicans: Incubate with shaking at 36±1℃ for 40-48h.

[0105] After incubation, remove the bacterial suspension and allow it to cool at 4°C. Perform serial dilutions using sterile PBS buffer and adjust the bacterial suspension concentration using turbidimetric methods.

[0106] Final working concentration: Dilute the bacterial suspension to a concentration of 1.0 × 10⁻⁶ using sterile PBS buffer. 8 ~ 5.0×10 8 CFU / mL (equivalent to 0.5 McFarland turbidity standard). The bacterial suspension at this concentration is the stock solution used in the experiment.

[0107] 1.2 Experimental Procedure 1.2.1 Experimental Grouping Experimental group: 5.0 mL of test sample.

[0108] Positive control group: 5.0 mL sterile PBS buffer + 0.1 mL bacterial suspension.

[0109] 1.2.2 Process of Action The test tubes of the experimental group and the positive control group were placed in a constant temperature water bath at 20±1℃ and preheated for 5 minutes.

[0110] Add 0.1 mL of the prepared bacterial suspension to the test tubes of the experimental group and the positive control group, mix quickly and start timing.

[0111] After 2 minutes of incubation, immediately take 0.5 mL of the mixture from the experimental group test tube and add it to a test tube containing 4.5 mL of sterile PBS buffer. Shake vigorously to mix well and dilute 10 times.

[0112] 1.2.3 Viable cell count Based on the estimated number of surviving bacteria from the preliminary experiment, the diluted bacterial solution was further serially diluted 10-fold (e.g., 10...). -1 10 -2 10 -3 (etc.), select 2-3 suitable dilutions.

[0113] Take 1.0 mL of bacterial culture for each dilution and inject it into a sterile Petri dish. Perform two replicates for each dilution.

[0114] Quickly pour the appropriate agar medium (nutrient agar for Escherichia coli and Staphylococcus aureus, and Sabouraud dextrose agar for Candida albicans) cooled to 45-50°C into the petri dish, gently rotate the petri dish to mix it thoroughly, and wait for it to solidify.

[0115] nourish: Escherichia coli and Staphylococcus aureus: Invert the container in a constant temperature incubator at 36±1℃ and incubate for 48 hours.

[0116] Candida albicans: Invert the container in a constant temperature incubator at 36±1℃ and incubate for 72 hours.

[0117] Meanwhile, the bacterial suspension of the positive control group was diluted and spread for culture to calculate the initial viable bacterial count.

[0118] 2. Quantitative antibacterial experimental data of suspension 2.1 Calculation of Antibacterial Rate In the formula, Y is the inhibition rate, %; I is the average viable bacterial concentration (CFU / mL) of the positive control group; and II is the average viable bacterial concentration (CFU / mL) of the experimental group after 2 min of treatment.

[0119] 2.2 Result Determination When the antibacterial rate is ≥90%, it indicates that the product has a strong antibacterial effect under this condition; when 50%≤antibacterial rate<90%, it indicates that the product has an antibacterial effect under this condition.

[0120] 2.3 Experimental Data Table 3: Real-time antibacterial experimental data of the dishwashing liquids prepared in the examples and comparative examples Table 4: Antibacterial test data of the dishwashing liquids prepared in the examples and comparative examples after four weeks of storage. 2.4 Experimental Conclusions The real-time suspension quantitative antibacterial test data showed that the multifunctional dishwashing liquid prepared in Example 1 and Comparative Example 4 had an antibacterial rate of >99.9% against Staphylococcus aureus, Escherichia coli and Candida albicans, which was significantly better than the standard dishwashing liquid of Comparative Example 1. This proves that the multifunctional dishwashing liquid of Example 1 has a strong antibacterial effect.

[0121] refer to Figures 3 to 8 The quantitative antibacterial test data of the suspension after four weeks of sample storage showed that the multifunctional dishwashing liquid prepared in Example 1 had no significant difference in antibacterial effect compared with the immediate antibacterial test. However, the dishwashing liquid of the acyclodextrin system in Comparative Example 4 showed a sharp drop in antibacterial effect. This is mainly because the cyclodextrin in Example 1 can molecularly encapsulate the natural antibacterial agent tea tree oil. The "molecular capsule" effect of cyclodextrin protects the effective components of tea tree oil, preventing its oxidation and rapid volatilization, thus ensuring the stability of the product. On the other hand, it enables the slow and controlled release of tea tree oil during use, thereby providing a long-lasting antibacterial and bacteriostatic effect. It can effectively inhibit common kitchen microorganisms such as Escherichia coli and Staphylococcus aureus, preventing secondary contamination and cross-infection of tableware.
