Description

Technical Field

[0001] The present application relates to the field of cosmetic technology, and in particular to a shower gel with deep cleansing and efficient whitening effects and a preparation method thereof. Background Art

[0002] Melanin, a pigment found in the basal layer of everyone's skin, is the primary culprit for skin whitening. Ultraviolet radiation changes melanin, transforming it into a skin-protecting substance. Melanin then migrates through cellular metabolism to the epidermis, causing visible skin problems like dark spots and uneven skin tone.

[0003] With the accelerating pace of modern life and rising health awareness, shower gel, as a daily cleansing product, is increasingly attracting consumers' attention for its quality and performance. While there are a wide variety of whitening shower gels on the market, they generally suffer from insufficient cleaning power and inefficient penetration of their whitening ingredients. Most products are based on traditional surfactant systems, lacking effective whitening ingredient delivery mechanisms, and thus fail to meet consumers' dual demands for deep cleansing and rapid whitening and anti-staining effects. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this application provides a body wash with deep cleansing and highly effective whitening effects and a preparation method thereof. The body wash prepared in this application has excellent mild cleansing and antibacterial effects. Through the synergistic effect of whitening plant extracts and whitening and freckle removal agents, it can comprehensively inhibit the synthesis and circulation of melanin, effectively reducing chloasma, ultraviolet spots, and inflammatory deposits, and quickly brightening the skin tone.

[0005] In the first aspect, the present application provides a shower gel with deep cleansing and efficient whitening effects, which adopts the following technical solutions: A shower gel with deep cleansing and efficient whitening effects comprises the following raw materials, calculated by weight: 0.08-0.12 parts of disodium edetate, 0.2-0.3 parts of a whitening plant extract, 8-10 parts of a detergent, 0.2-0.25 parts of a whitening and anti-freckle agent, 0.2-0.3 parts of a preservative, 0.3-0.4 parts of an antibacterial agent, 0.4-0.6 parts of pearlescent paste, 1.4-1.6 parts of sodium chloride, 0.2-0.3 parts of an essence, and 83-85 parts of deionized water.

[0006] By employing the above technical solution, disodium EDTA acts as a chelating agent, effectively removing metal ions from water and reducing their interference with whitening ingredients. The whitening plant extract is made from a blend of Paris polyphylla extract and citrus fruit extract. Citrus fruit extract is rich in natural fruit acids and vitamins, offering antioxidant and whitening benefits. Paris polyphylla extract contains β-ecdysterone, which inhibits the migration of melanocytes, thereby achieving a whitening effect. The cleanser is made from a blend of lauryl hydroxysultaine, cocamidomethyl MEA, and sodium lauryl ether sulfate. Lauryl hydroxysultaine provides superior cleansing and foaming properties. Cocamidomethyl MEA has moisturizing, detersive, and degreasing properties, helping to deep cleanse and maintain skin's water-oil balance. Sodium lauryl ether sulfate provides excellent detergency and emulsifying properties. The whitening and anti-freckle agent is made from a blend of glabridin nanoliposomes, ascorbyl tetraisopalmitate, diglucosylgallic acid, and dipotassium glycyrrhizate. Glabridin nanoliposomes release glabridin through lathering and kneading, regulating epidermal cell pigment synthesis; ascorbyl tetraisopalmitate inhibits the activity of melanin-producing enzymes; diglucosylgallic acid inhibits free radical production and melanin production; and dipotassium glycyrrhizate aids in whitening, inhibits melanin production, and promotes skin metabolism. Preservatives and antibacterial agents: Preservatives and antibacterial agents work together to prevent microbial growth, ensuring the stability and safety of the shower gel. Pearlescent slurry and thickener: Pearlescent slurry imparts a pearlescent texture to the shower gel, enhancing the user experience; thickeners such as sodium chloride help adjust the viscosity and stability of the shower gel. Fragrance: Provides a pleasant aroma, enhancing the user experience. Through the synergistic effect of these components, the shower gel of this application not only deeply cleanses the skin and removes oil and dirt, but also effectively inhibits melanin synthesis and transfer, reducing issues such as chloasma and UV spots, while providing a mild whitening effect. Furthermore, the synergistic effect of these ingredients enhances the skin's antioxidant capacity, promotes skin cell renewal, and maintains skin health.

[0007] Preferably, the whitening plant extract is prepared by mixing Paris polyphylla extract and citrus aurantium fruit extract in a mass ratio of 3:4-6.

[0008] By adopting the above technical solution, a whitening plant extract prepared by mixing Paris polyphylla extract and Citrus grandiflora fruit extract in a specific mass ratio plays a significant role. This blending method aims to leverage the individual properties of the two plant extracts and their synergistic effect to achieve enhanced whitening results. Paris polyphylla extract contains components such as β-ecdysterone, which can whiten skin by inhibiting the migration of melanocytes. It also inhibits tyrosinase activity, which helps reduce melanin production. Citrus grandiflora fruit extract, on the other hand, contains a variety of natural ingredients, such as natural fruit acids, vitamins, polyphenols, flavonoids, alkaloids, and sterols. These ingredients have antioxidant properties and can reduce the damage caused by oxygen free radicals in the skin caused by sun exposure. Furthermore, the salicylic acid in Citrus grandiflora fruit extract has antibacterial and anti-inflammatory properties, stimulating skin cell renewal and inhibiting melanin production, thereby whitening and brightening the skin tone. When these two extracts are mixed in a specific ratio, their synergistic effect can enhance the whitening effect. For example, the antioxidants in lemon fruit extract can help reduce the production of free radicals, thereby reducing melanin production. Simultaneously, ingredients in Paris polyphylla extract can inhibit melanocyte migration and tyrosinase activity, further reducing melanin formation. This synergistic effect not only enhances whitening effectiveness but also helps protect the skin from environmental damage. In summary, the synergistic effect of Paris polyphylla extract and lemon fruit extract is achieved through the complementary whitening properties of their respective ingredients, thereby enhancing the overall whitening effect and skin protection capabilities of the body wash.

[0009] Preferably, the preparation method of the lemon fruit extract is as follows: fresh lemon fruits are washed and placed in a -10°C low-temperature freezer for 3 hours; the lemon fruits are then crushed, and a 2% salicylic acid ethanol solution having the same weight as the crushed lemon fruits is added, the mixture is mixed evenly, and then mechanically squeezed, followed by ultrasonic treatment for 2 hours, and then filtered through a 10-100 mesh filter, a 400-600 mesh filter cloth, and a 1 μm filter membrane in sequence to obtain the filtrate, which is the lemon fruit extract.

[0010] The lemon fruit extract prepared using the above technical solution contains a variety of natural ingredients, such as natural fruit acids, vitamins, polyphenols, flavonoids, alkaloids, and sterols. These ingredients have antioxidant, anti-inflammatory, and whitening properties. Salicylic acid, in particular, has antibacterial and anti-inflammatory effects, promotes skin cell renewal, and inhibits melanin formation. Furthermore, the ingredients in lemon fruit extract absorb ultraviolet light, reducing skin damage caused by sun exposure. The lemon fruit extract works synergistically with other ingredients in the shower gel, such as whitening plant extracts and whitening and anti-freckle agents, to inhibit melanin synthesis and transport, reducing the formation of chloasma, ultraviolet spots, and inflammatory plaques. Furthermore, the salicylic acid in the lemon fruit extract works together with other ingredients, such as glabridin nanoliposomes, to regulate epidermal pigment synthesis and reduce melanin deposition, thereby achieving a skin whitening effect. Furthermore, the ingredients in lemon fruit extract can help improve skin dullness and hyperpigmentation, resulting in fairer and smoother skin. In summary, lemon fruit extract in shower gel not only exerts its own whitening effect, but also works synergistically with other ingredients to enhance the product's whitening effect and skin health.

[0011] Preferably, the cleaning agent is prepared by mixing lauryl hydroxysulfobetaine, cocamide methyl MEA and sodium lauryl ether sulfate in a mass ratio of 5:0.8:7-8.

Furthermore, Cocamidomethyl MEA is mild and low-irritating. Sodium Laureth Sulfate: Its excellent detergency and emulsifying properties effectively remove dirt and oil from the skin. It also provides excellent foam stability and a fine, rich lather, allowing the shower gel to produce a rich, delicate lather upon use, enhancing the user's enjoyment of the shower gel. Lauryl Hydroxysultaine and Sodium Laureth Sulfate work together to provide powerful cleansing power, removing oil, dirt, and impurities from the skin's surface. Furthermore, the addition of Cocamidomethyl MEA ensures a fine and stable foam, making the cleansing process more gentle and comfortable. Cocamidomethyl MEA and Lauryl Hydroxysultaine work together to maintain the skin's water-oil balance, preventing dryness and tightness caused by over-cleansing. Furthermore, the low irritation property of Cocamidomethyl MEA ensures the shower gel's mildness to the skin. The foaming and foam-stabilizing properties of cocamidomethyl MEA enhance the overall user experience of the shower gel, making the bathing process more comfortable. Furthermore, the rich foam helps evenly distribute and penetrate the whitening ingredients into the skin. In summary, this specific detergent blend ensures that the shower gel achieves the optimal balance between cleansing effectiveness, mildness, and user experience.

[0013] Preferably, the whitening and freckle-removing agent is prepared by mixing glabridin nanoliposomes, ascorbyl tetraisopalmitate, diglucosylgallic acid and dipotassium glycyrrhizate in a mass ratio of 10:5:1:2.

[0014] By adopting the above technical solution, glabridin nanoliposomes: Glabridin is an ingredient with multiple benefits, including anti-inflammatory, anti-allergic, antioxidant, and whitening properties. Its application in nanoliposome form improves its stability and permeability in the skin, thereby more effectively regulating epidermal pigment synthesis, reducing melanin deposition, and achieving a skin whitening effect. Ascorbyl tetraisopalmitate: This vitamin C derivative inhibits the activity of melanin production enzymes, reducing melanin production and achieving a skin whitening effect. It also has multiple benefits, including antioxidant, collagen synthesis promotion, anti-inflammatory, and moisturizing properties, comprehensively protecting skin health. Diglucosylgallic acid: This ingredient works by activating the skin's microbiome, offering whitening, anti-inflammatory, and photoprotective properties. It helps inhibit free radical production and counteract UV damage to skin DNA. It also controls the migration of melanin to the skin's surface and reduces melanin synthesis. Dipotassium glycyrrhizate: This ingredient aids in skin whitening, inhibits melanin production, forms a natural barrier against UV rays, and promotes skin metabolism. It inhibits tyrosinase activity, reducing melanin production, while also forming a natural UV barrier to prevent sunburn and dark spots. The synergistic effect of these ingredients lies in their complementary and enhanced whitening and antioxidant properties. Glabridin nanoliposomes and ascorbyl tetraisopalmitate work together to activate melanin production and transfer, while diglucosylgalactone provides additional anti-inflammatory and photoprotective benefits. Dipotassium glycyrrhizate enhances the overall effect through its unique whitening and barrier-forming properties. This combination comprehensively inhibits melanin synthesis and transport, effectively reducing melasma, UV-induced spots, and inflammatory plaques, resulting in a rapid and effective whitening and brightening of the complexion. Furthermore, the synergistic effect of these ingredients enhances the skin's antioxidant capacity, reducing skin damage and aging caused by sun exposure.

[0015] Preferably, the preparation method of the glabridin nanoliposomes is as follows: 12 parts of glabridin, 7 parts of phosphoglyceride, 5 parts of polyoxyethylene sorbitan monopalmitate, 4 parts of cholesterol and 70 parts of n-dodecane are mixed uniformly according to mass parts, stirred at 73°C and 400 r / min for 20-30 minutes, 36 parts of pentaerythritol and 70 parts of deionized water are added dropwise at a uniform speed within 20 minutes, and stirring is continued for 30 minutes to obtain colostrum; the colostrum is then treated 4-5 times by a high-pressure homogenizer at 900 bar to obtain glabridin nanoliposomes.

[0016] By adopting the above-mentioned technical solution, the preparation method of glabridin nanoliposomes involves multiple steps and components. These components interact to form stable nanoliposomes, thereby improving the solubility and stability of glabridin. Glabridin: As the main component, glabridin possesses all the physiological activities of vitamin C, inhibiting the activity of melanin-producing enzymes, reducing melanin production, and achieving a whitening effect. It also has multiple benefits, including antioxidant, collagen synthesis promotion, anti-inflammatory, and moisturizing properties. Phosphoglyceride: As an emulsifier, phosphoglyceride helps form a stable emulsion system, allowing glabridin to be evenly dispersed between the oil and aqueous phases. Polyoxyethylene sorbitan monopalmitate: A surfactant that helps improve the solubility and stability of glabridin and also facilitates the emulsification process. Cholesterol: As a component of the liposomes, cholesterol helps form a stable lipid bilayer structure, enhancing the stability of the nanoliposomes. n-Dodecane: As an oil phase component, n-dodecane helps form the emulsification system and also provides a solubility environment for glabridin. Pentaerythritol: As a polyol, pentaerythritol helps regulate the pH of the emulsified system and also serves as a thickener. Deionized water: As the aqueous phase component, deionized water helps regulate the moisture content of the emulsified system and also provides a solubility environment for glabridin. Through the above steps and the interaction of the ingredients, the resulting glabridin nanoliposomes exhibit high stability and solubility. When used in body wash, these nanoliposomes rupture on the skin surface, releasing glabridin, thereby exerting its whitening and antioxidant benefits. This nanoliposome preparation method also helps improve the efficiency and effectiveness of glabridin.

[0017] Preferably, the preservative is phenoxyethanol; and the antibacterial agent is Antimicro RP-11, which is used to inhibit the growth of microorganisms.

After gently rubbing for 2-3 minutes, rinse with warm water. Use once a day for 2 consecutive weeks. The scores of each group of subjects were counted, and the average score was calculated. The test results are shown in Table 2.

[0043] Table 2 Trial score record 3. Whitening effect test The shower gels with deep cleansing and efficient whitening effects were prepared for Example 1-Example 3 and Comparative Example 1-Comparative Example 7 respectively and tested on humans using a skin tester. 50 female volunteers (age range 20-50 years old) were randomly selected and used Example 1-Example 3 and Comparative Example 1-Comparative Example 7 in sequence to prepare shower gels with deep cleansing and efficient whitening effects as a whitening set, once a day in the morning and evening, and discontinued after 12 weeks of continuous use. Full-face images were collected using VISIA four light sources, and photos were taken before use as blank controls. Face data was collected every four weeks, and a total of 12 samples were taken (including controls). The test items included three-dimensional analysis of sample data for skin light spot area (number) and dark spot area (number), and the results are shown in Table 3.

[0044] Table 3 Whitening effect Analyzing the data in Tables 1 to 3, we can see that: 1) The shower gels with deep cleansing and efficient whitening effects prepared in Examples 1 to 3 have excellent mild and efficient deep cleansing of the skin and good antibacterial effects. At the same time, by utilizing the synergistic effect between the whitening plant extracts and the whitening and freckle removal agents, the synthesis and operation of melanin are comprehensively inhibited, effectively reducing chloasma, ultraviolet spots, and inflammatory deposits, and quickly and efficiently whitening and brightening the skin tone.

[0045] 2) A comparative analysis of the performance of the shower gels with deep cleansing and efficient whitening effects prepared in Example 3 and Comparative Examples 1-2 shows that the synergistic effect between the whitening plant extracts and the whitening and freckle removal agents comprehensively inhibits melanin synthesis and circulation, effectively reduces chloasma, ultraviolet spots, and inflammatory deposits, and quickly and efficiently whitens and brightens the skin tone.

[0046] 3) A comparative analysis of the performance of the shower gels with deep cleansing and efficient whitening effects prepared in Example 3 and Comparative Examples 3-4 shows that the whitening plant extract is prepared by mixing Paris polyphylla extract and citrus fruit extract in a mass ratio of 3:5. This synergistic effect is achieved by complementing their respective whitening ingredients and properties, thereby improving the overall whitening effect and skin protection ability of the shower gel. For example, the antioxidant components in citrus fruit extract can help reduce the production of free radicals, thereby reducing the production of melanin; at the same time, the components in Paris polyphylla extract can inhibit the migration of melanocytes and the activity of tyrosinase, further reducing the formation of melanin. This synergistic effect not only improves the whitening effect but also helps protect the skin from environmental damage.

[0047] 4) A comparative analysis of the performance of the shower gels with deep cleansing and efficient whitening effects prepared in Example 3 and Comparative Examples 5-7 shows that the cleanser is prepared by mixing lauryl hydroxysulfobetaine, cocamide methyl MEA, and sodium lauryl ether sulfate in a mass ratio of 5:0.8:7. The synergistic effect between them can ensure that the shower gel achieves the best balance between cleaning effect, mildness, and user experience.
