[0071] Experimental performance testing

[0072] 1. Bacterial culture, such as Figure 1 As shown, *Trichophyton rubrum* was cultured. *Trichophyton rubrum* belongs to the genus *Trichophyton* and is a human-dermatophyte, classified as belonging to the domain Eukaryoteae and subphylum Discomycetes. It is a pathogen causing common superficial fungal infections of the skin, including tinea manuum, tinea pedis, tinea capitis, tinea cruris, and onychomycosis, and has a high isolation rate among patients with fungal dermatophyte infections worldwide.

[0073] Morphological characteristics: Colony morphology: The front side is usually granular or fluffy, and the color is white to light yellow; the back side is dark red or slightly purple, and occasionally it can be brown, orange-yellow or colorless. It easily produces pigments on potato dextrose agar or corn dextrose agar.

[0074] Figure 1 It is cultured from freeze-dried powder of Trichophyton rubrum and its morphology conforms to the standard morphology of Trichophyton rubrum.

[0075] 2. Antibacterial experiment of freeze-dried garlic powder;

[0076] Figure 2(a) and Figure 2(b) show the antibacterial effect of freeze-dried garlic powder. Figure 2(a) shows the solution with added freeze-dried garlic powder, and Figure 2(b) shows the control group with added sterile water.

[0077] In conducting the experiment, we first selected Trichophyton rubrum, which was cultured on a solid culture medium under suitable conditions, was in good growth condition, and had typical colony morphology.

[0078] The fungal blocks were cut into uniform sizes (approximately 5mm × 5mm) using a sterile scalpel to ensure the consistency and reproducibility of the experiment. Subsequently, in a sterile operating table, the Trichophyton rubrum fungal blocks were transferred to an Erlenmeyer flask containing 20mL of liquid culture medium using sterile forceps. The Erlenmeyer flask was then placed in a constant temperature shaker at 37℃ and 150r / min for 24h of shaking culture. This process promotes the full growth and reproduction of Trichophyton rubrum in the liquid culture medium, resulting in a uniform concentration and good viability of the fungal suspension.

[0079] After incubation, the bacterial suspension was appropriately diluted using a serial dilution method to obtain a suitable concentration. 0.1 mL of the diluted suspension was taken and evenly spread onto the surface of the solid culture medium using a sterile spreader, ensuring complete coverage of the petri dish surface to form a basis for single colony growth. After spreading, once the bacterial suspension was fully absorbed, a sterile punch (6 mm in diameter) was used to vertically punch a hole in the center of the petri dish, removing the agar block to create circular pores and construct a specific area for drug action.

[0080] Next, the pre-prepared freeze-dried garlic powder (using vacuum freeze-drying technology to maximize the preservation of the bioactivity of the active ingredients in garlic) was dissolved in sterile physiological saline to prepare a 10 mg / mL solution. Using a pipette, 200 μL of the freeze-dried garlic powder solution was accurately pipetted and slowly added to the gaps in the center of the petri dish, ensuring even distribution of the solution within the gaps. The treated petri dishes were then placed in a 37°C incubator and inverted for 24 hours to avoid the influence of condensation on colony growth during the incubation process.

[0081] The experimental results showed that no Trichophyton rubrum colonies were formed in the central area of ​​the petri dish, indicating that the garlic freeze-dried powder solution had a significant inhibitory effect on Trichophyton rubrum under the experimental conditions.

[0082] 3. Prepare freeze-dried garlic powder foot mask;

[0083] The formulation and preparation process of the foot mask essence are as follows: In a clean laboratory environment, 1.000g of carbomer polymer was accurately weighed using a precision electronic balance (accuracy 0.001g) and slowly added to 50.000g of double-distilled deionized water. The mixture was continuously stirred at 80r / min using a magnetic stirrer to ensure thorough dispersion of the carbomer in the deionized water, followed by standing soaking and swelling for 2 hours. During this process, carbomer molecules bind with water molecules through hydrogen bonds, gradually forming a gel system with a three-dimensional network structure, providing a stable matrix for the subsequent addition of ingredients.

[0084] After the carbomer has fully swelled and formed a uniform gel, the functional ingredients are added sequentially according to the predetermined formula. First, 10,000g of pharmaceutical-grade glycerin is added as a moisturizer. It forms hydrogen bonds with water molecules through hydroxyl groups, enhancing the moisturizing properties of the serum. Then, 0.500g of medical-grade sodium hyaluronate is added, utilizing its unique molecular structure to achieve highly efficient water-locking function. Next, 5,000g of aloe vera extract prepared by ultrasound-assisted extraction is added. This extract is rich in polysaccharides, flavonoids, and other active ingredients, and has excellent soothing and repairing effects. Finally, 2,000g of lavender essential oil extracted by steam distillation and 1,000g of safflower essential oil obtained by supercritical CO2 extraction technology are added. These two plant essential oils not only give the product a natural fragrance but also have antibacterial and anti-inflammatory biological activities.

[0085] During the addition of each of the above components, a stirrer was used to continuously stir at a speed of 120 r / min for 15 minutes to ensure that each component was evenly dispersed.

[0086] Finally, 5,000g of freeze-dried garlic powder was added to the system, and the freeze-dried garlic powder was fully dispersed and mixed evenly with other ingredients by using low-speed stirring (60r / min) combined with intermittent ultrasonic treatment (power 200W, 3 minutes each time, 5 minutes interval, for a total of 3 treatments) to finally obtain a foot mask essence with antibacterial, moisturizing and soothing effects.

[0087] 4. Experiment on the antibacterial effect of freeze-dried garlic powder on foot membranes;

[0088] like Figure 3 The antibacterial effect diagrams shown, from left to right, are: sterile water control group, normal model group, and foot mask essence antibacterial model group.

[0089] The experimental procedure is the same as that for the antibacterial experiment of garlic freeze-dried powder solution.

[0090] 5. Measurement of garlic freeze-dried powder solution and the antibacterial zone of garlic freeze-dried powder foot film;

[0091] Figure 4(a) and Figure 4(b) show the measurement of the inhibition zone. Figure 4(a) shows the inhibition zone of different doses of garlic freeze-dried powder solution, and Figure 4(b) shows the inhibition zone of garlic freeze-dried powder foot film.

[0092] Figure 4(a) shows the diameters of the inhibition zones of the garlic freeze-dried powder solution at three concentrations of 25 mg / mL, 50 mg / mL, and 100 mg / mL, from top to bottom. The diameters are 8.3±0.6 mm, 10.5±0.8 mm, and 15.7±1.2 mm, respectively, showing a concentration-dependent inhibition trend.

[0093] Figure 4(b) shows that the diameter of the inhibition zone of the freeze-dried garlic foot film is 43.69 mm, which is much larger than the diameter of the inhibition zone at each concentration on the left. This indicates that the freeze-dried garlic foot film has stronger antibacterial ability and higher antibacterial activity under the current conditions.

[0094] Performance tests were conducted on the garlic freeze-dried powder foot mask prepared in the above embodiments. The results showed that the foot mask of the present invention has good moisturizing, antibacterial, exfoliating and blood circulation-improving effects on the feet, and is gentle and non-irritating to the skin, with significant effects.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
