[0057] S6. Add auxiliary components: Add clotrimazole, dipotassium glycyrrhizinate, and allantoin to the above-mentioned mixed solution, and continue to stir for 20 - 30 minutes;

[0058] S7. Adjust the pH value: Slowly adjust the pH value of the mixed solution to 3.8 - 4.5 with lactic acid;

[0059] S8. Filter and fill: Filter the finally obtained cleaning solution through a 0.22 μm microporous filter membrane to remove possible impurities, and then perform aseptic filling.

[0060] In this embodiment, in the step of dissolving the humectant, the stirring speed is controlled at 200 - 300 revolutions per minute.

[0061] In this embodiment, in the step of mixing the main components, the stirring is carried out in an alternating manner of clockwise and counterclockwise, and the stirring time for each direction is 15 - 20 minutes.

[0062] In this embodiment, after the step of filtering and filling, it also includes quality inspection of the filled cleaning solution, and the inspection items include appearance, pH value, and microbial limit.

[0063] Specifically, two processing process parameters are adopted according to the raw materials with two component ratios:

[0064] The first process parameter: According to the raw materials with the first component ratio, glycerol and sodium hyaluronate are added to deionized water, and at 45°C, it is constantly stirred at a stirring speed of 250 revolutions per minute until completely dissolved to obtain a moisturizing agent solution. This process is carried out in a stainless steel reactor with heating and stirring functions. The heating is achieved through circulating hot water in the jacket, and a stirring paddle is used for stirring to ensure that the solution is evenly heated and fully stirred.

[0065] The chamomile extract and tea tree essential oil are mixed evenly at room temperature at a stirring speed of 120 revolutions per minute and continuously stirred for 18 minutes to obtain a plant extract mixture. The mixing container used is a glass container with a stirrer to avoid the influence of metal ions on the activity of the plant extract.

[0066] Cocamidopropyl betaine is added to an appropriate amount of deionized water and stirred at a speed of 350 revolutions per minute for 25 minutes to prepare a surfactant solution.

[0067] The moisturizing agent solution, the plant extract mixture, and the surfactant solution are successively added to another reactor. At 28°C, it is first stirred clockwise for 20 minutes, then counterclockwise for 20 minutes, and the stirring speed is 200 revolutions per minute to make the solutions fully mixed.

[0068] Then clotrimazole, dipotassium glycyrrhizinate, and allantoin are added to the above mixture and continuously stirred at a speed of 250 revolutions per minute for 25 minutes.

[0069] Using a precision pH meter, lactic acid is slowly added dropwise while stirring until the pH value of the mixture reaches 4.0.

[0070] Finally, the cleaning solution is filtered through a 0.22μm microporous filter membrane and filtered using a positive pressure filtration system, and aseptic filling is carried out using an automatic filling machine in a hundred-class clean area. The filling volume of each bottle of product is 200ml.

[0071] The second process parameter: According to the raw materials with the second component ratio, glycerol, sodium hyaluronate, and trehalose are put into a reactor filled with deionized water, and at 42°C, it is stirred at a speed of 280 revolutions per minute until completely dissolved to form a moisturizing agent solution. The heating is carried out through an electric heating mantle, and the stirring paddle is made of polytetrafluoroethylene material to prevent reaction with the raw materials.

[0072] The chamomile extract, tea tree essential oil, and witch hazel extract are stirred in a glass mixing tank at a speed of 130 revolutions per minute for 16 minutes to obtain a plant extract mixture.

[0073] Cocamidopropyl betaine is stirred in an appropriate amount of deionized water at 380 revolutions per minute for 22 minutes to prepare a surfactant solution.

[0074] Add the above three solutions to the reaction kettle in sequence. At 26°C, first stir clockwise for 18 minutes, then stir counterclockwise for 18 minutes, and the stirring speed is 220 revolutions per minute to mix evenly.

[0075] Subsequently, clotrimazole, dipotassium glycyrrhizinate, allantoin and lavender essential oil are added, and stirring is continued for 28 minutes, and the stirring speed is 260 revolutions per minute.

[0076] Use a pH meter to adjust the pH value to 4.2, and stir while adding lactic acid during the process.

[0077] Filter through a 0.22 μm filter membrane using a sterile filtration device, and perform aseptic filling in a Class 100 clean area, with a filling volume of 300 ml.

[0078] Example 2:

[0079] Comparative experiment:

[0080] Use the intimate cleansing liquid with the two ingredient ratios in Example 1 and a common intimate cleansing liquid on the market as a comparative example. The main ingredients of this cleansing liquid include common surfactants and a small amount of plant extracts, and there are no special antifungal, anti-inflammatory and soothing ingredients for the comparative experiment. The specific test process is as follows:

[0081] Experiment 1. Itching relief effect test:

[0082] Select 120 female volunteers with intimate itching symptoms and randomly divide them into three groups, with 40 people in each group. Use the cleansing liquid with the first ingredient ratio, the cleansing liquid with the second ingredient ratio and the comparative example cleansing liquid respectively, once a day for 7 consecutive days. Record the improvement of itching symptoms before and after use.

[0083] The results show that among the volunteers using the cleansing liquid with the first ingredient ratio, 32 people had significantly reduced itching symptoms, accounting for 80%; among the volunteers using the cleansing liquid with the second ingredient ratio, 34 people had significantly reduced itching symptoms, accounting for 85%; while among the volunteers using the comparative example cleansing liquid, only 18 people had significantly reduced itching symptoms, accounting for 45%. Thus, it can be seen that the cleansing liquid of the present invention has a significantly better itching relief effect than the common cleansing liquid.

[0084] During the use process, it is required that the volunteers use the cleansing liquid at the same time every day. When using, apply an appropriate amount of the cleansing liquid to the intimate area, let it stay for 1 - 2 minutes and then rinse it off with clean water, and record the use experience, including subjective feelings such as whether there is a cool feeling and whether it is stimulating.

[0085] Experiment 2. Skin irritation test:

[0086] Using the human skin patch test method, 60 healthy volunteers were selected and randomly divided into three groups of 20 people each. The cleaning solutions with the first ingredient ratio, the cleaning solution with the second ingredient ratio, and the control cleaning solution were respectively applied to the fixed area on the inner side of the volunteers' arms, and the skin reactions were observed after 24 hours and 48 hours.

[0087] The results showed that no obvious irritation reactions such as redness, swelling, and stinging occurred on the skin of the volunteers who used the cleaning solutions with the first ingredient ratio and the second ingredient ratio; among the volunteers who used the control cleaning solution, 5 people had mild skin redness, accounting for 25%. This indicates that the cleaning solution of the present invention is less irritating to the skin and more gentle.

[0088] The patch material for the patch test was medical adhesive tape. The area for applying the cleaning solution was 1 cm × 1 cm. After application, it was covered with a transparent film to ensure that the patch was closely attached to the skin. During the observation period, the volunteers were kept away from water to ensure the accuracy of the test.

[0089] In summary, clotrimazole can effectively inhibit the growth of fungi and has a significant therapeutic effect on private part itching caused by fungal infections; dipotassium glycyrrhizinate exerts anti-inflammatory properties and can relieve the itching symptoms caused by inflammation; allantoin has the effect of soothing the skin and can relieve the itching sensation caused by various stimuli. These ingredients work synergistically, making the anti-itching effect of the present invention significantly better than that of ordinary cleaning solutions. Moreover, the mild surfactant cocamidopropyl betaine is selected to avoid over-cleaning the skin of the private parts. At the same time, lactic acid is used to adjust the pH value of the cleaning solution to the physiological pH range of the private parts (3.8 - 4.5), which helps to maintain the acid-base balance and microecological environment of the private parts. Natural plant extracts such as chamomile extract and tea tree essential oil not only have antibacterial and anti-inflammatory functions but also can reduce the irritation to the skin, making the cleaning solution mild in nature, suitable for daily use, and having good protective and nurturing effects on the skin of the private parts.
