Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, specifically to a composition with whitening and anti-wrinkle effects and its application. Background Technology

[0002] Theanine, scientifically known as γ-glutamylethylamine, is a non-protein amino acid unique to tea, with the molecular formula C7H. 10 N2O3 is the main component in tea that promotes salivation and sweetness. It has calming, anti-fatigue, memory-enhancing, nerve-protecting, and blood pressure-lowering effects. It can also promote the generation of alpha waves in the brain, which helps relieve stress and anxiety.

[0003] Tiger Orchid (Orchid simonii) is a plant belonging to the Orchid genus of the Orchidaceae family. Its extracts contain a variety of bioactive components, such as flavonoids, polysaccharides, and volatile oils. Flavonoids have antioxidant, anti-inflammatory, and UV-absorbing properties, helping to protect the skin from oxidative damage and UV rays. Polysaccharides enhance the skin's moisturizing properties and promote skin cell metabolism, while volatile oils have certain antibacterial and anti-inflammatory effects, helping to maintain the skin's microecological balance.

[0004] Sophora japonica fruit is the fruit of the Sophora japonica plant, a legume. Its extracts mainly include flavonoids and other components. Flavonoids have antioxidant and free radical scavenging abilities, which help delay skin aging and reduce wrinkle formation. However, the content of active ingredients in existing Sophora japonica fruit extracts is not high, affecting the content and composition of active ingredients in the extracts and downstream products, thus affecting their efficacy. Summary of the Invention

[0005] In a first aspect, the present invention provides a composition having whitening and anti-wrinkle effects, wherein, by weight, the composition comprises 1-6 parts of theanine, 0.2-0.8 parts of *Cymbidium goeringii* extract and 0.2-2 parts of *Sophora japonica* fruit extract.

[0006] The inventors discovered that combining theanine, *Cymbidium goeringii* extract, and *Sophora japonica* fruit extract significantly enhances the whitening and anti-wrinkle effects, achieving a synergistic effect. *Sophora japonica* fruit extract is rich in polyphenols (flavonoids, phenolic acids), which are potent free radical scavengers. They can directly neutralize free radicals by providing hydrogen atoms, inhibiting lipid peroxidation and protecting cell membranes. Theanine, due to its unique structure (amide bond, amino group), can effectively chelate metal ions, blocking the chain reaction of free radicals catalyzed by metal ions and directly scavenging some free radicals. Both *Sophora japonica* fruit extract and theanine cover the needs for scavenging both water-soluble and lipid-soluble free radicals; their combination effectively expands the scope and efficiency of free radical scavenging. The extract of *Cymbidium goeringii* contains genes related to enhancing cell repair and proliferation, thereby improving skin cell repair capabilities and increasing epidermal thickness. While theanine and *Sophora japonica* extract scavenge external free radicals, the extract of *Cymbidium goeringii* activates and strengthens the skin cells' own antioxidant and repair capabilities within the cells. These three components, through external free radical scavenging and endogenous enhanced repair, form a synergistic "exogenous scavenging + endogenous enhancement" antioxidant system, significantly enhancing the whitening, antioxidant, and repair capabilities of the composition. Its efficacy far surpasses that of a single ingredient or a combination of two components—when the composition contains only one or two components, its whitening and anti-wrinkle effects are significantly inferior to the three-component combination. The inventors also discovered that not all whitening and antioxidant components can be combined with the components of this invention to obtain a composition with excellent whitening and anti-wrinkle effects. Furthermore, controlling the amounts of theanine, *Cymbidium goeringii* extract, and *Sophora japonica* extract within a certain range can yield a composition with even better whitening and anti-wrinkle effects.

[0007] In some embodiments, the Sophora japonica fruit extract undergoes purification, which includes the following steps: dissolving the crude Sophora japonica fruit extract, eluting it using a macroporous adsorption resin, collecting the eluent, and concentrating it to obtain the Sophora japonica fruit extract. The inventors have found that purifying and eluting the crude Sophora japonica fruit extract using a macroporous adsorption resin effectively removes impurities (such as water-soluble impurities, fat-soluble impurities, pigments, organic acids, etc.) from the crude extract. These impurities may affect the target sites of the Sophora japonica fruit extract, theanine, and *Cymbidium goeringii* extract, thereby affecting the compounding effect of the Sophora japonica fruit extract with theanine and *Cymbidium goeringii* extract. Purifying the crude Sophora japonica fruit extract reduces the possibility of adverse interactions with other active ingredients (theanine and *Cymbidium goeringii* extract), ensuring that the active ingredients in the three components can coexist stably in the formulation and maintain their activity, allowing the three components to better synergistically enhance their effects and further improve the whitening and anti-wrinkle efficacy of the composition. In some preferred embodiments, the macroporous adsorption resin includes at least one of AB-8, D101, and NKA-9 types. In some preferred embodiments, the macroporous adsorption resin includes at least one of AB-8 and D101 types.

[0008] In some embodiments, the eluent used for elution is an aqueous solution containing ethanol and hydrochloric acid, wherein the volume percentage of ethanol is 30-65%, the mass percentage of hydrochloric acid is 0.5-2%, and the elution flow rate is 2-6 BV / h. In some preferred embodiments, the volume percentage of ethanol is 45-55%, the mass percentage of hydrochloric acid is 0.8-1.2%, and the elution flow rate is 2-4 BV / h.

[0009] In a second aspect, the present invention provides the use of the above-described composition in cosmetics, said cosmetics including serums, lotions, lotions, creams, facial cleansers, masks, sunscreens, and makeup products.

[0010] In a third aspect, the present invention provides a cosmetic product comprising the above-described composition.

[0011] In some embodiments, the composition is added to the cosmetic at an amount of 1.4-8.8%.

[0012] In some embodiments, the cosmetic product further includes cosmetic-acceptable excipients, including at least one of skin conditioning agents, moisturizers, emulsifiers, and preservatives.

[0013] In some preferred embodiments, the skin conditioning agent includes at least one of glycerin and squalane, the moisturizer includes at least one of caprylic / capric triglyceride and jojoba oil, the emulsifier includes at least one of cetearyl oleate and sorbitan oleate, and the preservative includes phenoxyethanol.

[0014] In a fourth aspect, the present invention provides a method for preparing the above-mentioned cosmetic, characterized by comprising the following steps:

[0015] S1. Add squalane, caprylic / capric triglyceride and jojoba oil, stir to obtain an oil phase solution;

[0016] S2. Add deionized water, glycerin, *Cymbidium goeringii* extract, and *Sophora japonica* fruit extract, stir well, then add theanine and stir well to obtain an aqueous solution.

[0017] S3. Heat the oil phase solution obtained in step S1 and the aqueous phase solution obtained in step S2 to 70-85℃ respectively, and keep warm for 10-15 minutes.

[0018] S4. Pour the oil phase solution from step S3 into the aqueous phase solution and stir for 25-40 minutes at a speed of 2000-3000 rpm to form a primary emulsion.

[0019] S5. Stop heating and wait for the primary emulsion to cool to 40-50℃. During this time, keep stirring at a speed of 700-900 rpm. When the temperature of the primary emulsion drops to 40-50℃, add phenoxyethanol and continue stirring for 10-15 minutes.

[0020] S6. The cooled emulsion is homogenized at a speed of 1500-2500 rpm and a pressure of 10-15 MPa.

[0021] S7. Let the emulsion from step S6 stand for 12-24 hours to obtain the cosmetic product.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This invention combines theanine, *Cymbidium goeringii* extract, and *Sophora japonica* fruit extract. The three components significantly enhance the whitening and anti-wrinkle effects. Through external scavenging of free radicals and endogenous enhancement of repair, the three components form a synergistic "exogenous scavenging + endogenous enhancement" antioxidant system, which greatly enhances the whitening and anti-wrinkle capabilities of the composition. Its efficacy is far superior to that of a single component or a combination of two components, and it has good application prospects in the cosmetics field. Attached Figure Description

[0024] Figure 1 The image shows the emulsion product prepared in Example 1. Detailed Implementation

[0025] The following detailed embodiments further illustrate the content of the present invention. These embodiments do not constitute a limitation on the scope of protection of the present invention. Non-essential modifications and adjustments made by others based on the concept of the present invention still fall within the scope of protection of the present invention. In the following embodiments and comparative examples, unless otherwise specified, the experimental methods used are conventional methods, and the materials and reagents used are commercially available unless otherwise specified.

[0026] Theanine can be obtained through conventional commercial means or prepared according to Chinese patent CN118165969A. The theanine used in the examples was prepared according to Chinese patent CN118165969A.

[0027] Tiger Orchid Extract, powder, purchased from Shaanxi Senyuan Biotechnology Co., Ltd.

[0028] Bitter orange extract, powder, purchased from Shaanxi Bolin Biotechnology Co., Ltd.

[0029] Tea extract, purchased from Shanghai Zhongfeng Biotechnology Co., Ltd.

[0030] Tea polyphenols were purchased from Hubei Haijia Biotechnology Co., Ltd.

[0031] Red orchid extract was purchased from Lanzhou Waterles Biotechnology Co., Ltd.

[0032] AB-8 type macroporous adsorption resin was purchased from Bengbu Sanyi Technology Co., Ltd.

[0033] D101 type macroporous adsorption resin was purchased from Bengbu Sanyi Technology Co., Ltd.

[0034] NKA-9 macroporous adsorption resin was purchased from Elest (Shanghai) New Material Technology Co., Ltd.

[0035] Crude extract of Sophora japonica fruit was purchased from Baoji Fang Sheng Biotechnology Development Co., Ltd.

[0036] The Sophora japonica fruit extract of the present invention undergoes purification treatment, which includes the following steps:

[0037] (1) Resin pretreatment: The resin was soaked in 95% ethanol for 24 hours, with stirring every 5 hours at a speed of 70 rpm to ensure the ethanol fully penetrated the resin pores and removed small molecule impurities and residual organic matter from the production process. After soaking, the resin was rinsed with deionized water at a flow rate of 8 BV (bed volume) / h until the effluent showed no white turbidity upon addition of ethanol, ensuring complete ethanol washing. The resins used were AB-8, D101, and NKA-9 macroporous adsorption resins, respectively.

[0038] (2) Acid-base treatment: First, pass a 3 mol / L hydrochloric acid solution through the resin column at a flow rate of 4 BV / h for 2.5 hours to remove impurities such as metal ions from the resin. Then, treat with a 3 mol / L sodium hydroxide solution at the same flow rate and time to neutralize the residual acid and further remove impurities. Afterward, rinse with deionized water until the pH of the effluent is 6-7, i.e., neutral.

[0039] (3) Preparation of aqueous solution and column adsorption: 15g of crude Sophora japonica fruit extract (purchased from Baoji Fangcheng Biotechnology Development Co., Ltd.) was diluted to 1L with solvent to prepare an aqueous solution with a concentration of 15mg / mL. The solution temperature was controlled at 30℃ to avoid affecting the activity of alkaloids and the adsorption effect of the resin due to excessively high or low temperatures. The aqueous solution was passed through the resin column at a flow rate of 2BV / h. The flow rate was controlled to prevent insufficient contact time between the alkaloids in the Sophora japonica fruit extract and the resin, resulting in incomplete adsorption, and to prevent the flow rate from being too slow, which would affect production efficiency. Thin-layer chromatography (TLC) was used to monitor the alkaloid content in the eluent in real time. When the spot corresponding to the alkaloid in the eluent on the TLC plate became very light in color or disappeared, it was considered the adsorption endpoint.

[0040] (4) Elution and collection: Prepare an eluent of 50% ethanol + 0.8% hydrochloric acid and elute at a flow rate of 3 BV / h. Collect the eluent and closely observe the color change of the eluent during the elution process. When the color no longer changes and the alkaloid content in the eluent is extremely low as detected by TLC, stop elution.

[0041] (5) Collect the purified Sophora japonica fruit extract: The eluent is subjected to vacuum distillation at a temperature of 45°C and a pressure of -0.07 MPa. Ethanol is recovered for reuse to obtain a purified Sophora japonica fruit extract solution.

[0042] (6) Test the weight of the purified Sophora japonica fruit extract: Dry the evaporating dish at 105℃ for 2 hours, cool it in a desiccator, and weigh it using an electronic balance, recording the weight as m1. Pour the purified Sophora japonica fruit extract solution into the evaporating dish, evaporate it to near dryness in a 45℃ water bath, and then dry the solvent at 35℃. Place the evaporating dish in a 45℃ oven to dry for 3 hours, remove it, cool it, and weigh it. Repeat the drying process for 1 hour and weigh it again. If the difference between the two weights is ≤0.5mg, record the final mass as m2. Calculate the weight of the Sophora japonica fruit extract in the eluted filtrate as m2-m1.

[0059] The composition and dosage of the compositions in the examples and comparative examples are shown in Table 4.

[0060] Table 4

[0061]

[0062]

[0063] Example 12: The composition and dosage of the composition are the same as those in Example 1. The only difference from Example 1 is that, in the preparation of the purified Sophora japonica fruit extract, the flow rate of the eluent in the purification step (4) is 6 BV / h.

[0064] Example 13: The composition and dosage of the composition are the same as those in Example 1. The only difference from Example 1 is that, in the preparation of the purified Sophora japonica fruit extract, the eluent in the purification step (4) is an aqueous solution containing 30% ethanol and 0.6% hydrochloric acid.

[0065] Example 14: The composition and dosage of the composition are the same as those in Example 1. The only difference from Example 1 is that in the preparation of the purified Sophora japonica fruit extract, the eluent in the purification step (4) is an aqueous solution containing 65% ethanol and 2% hydrochloric acid.

[0066] Comparative Example 13: The only difference from Example 1 is that tea extract was used instead of theanine. Tea extract has whitening and antioxidant effects.

[0069] Comparative Example 16: The only difference from Example 1 is that the extract of *Cymbidium goeringii* was used instead of *Cymbidium faberi* extract. *Cymbidium goeringii* extract can help the skin resist free radical damage, slow down skin aging, and has antioxidant effects.

[0070] Comparative Example 17: The composition and weight parts of the composition of Comparative Example 17 are: 4 parts theanine, 0.8 parts crude extract of Sophora japonica fruit, and 0.5 parts extract of Cymbidium goeringii.

[0071] Emulsion preparation

[0072] The compositions of the examples and comparative examples were prepared into emulsions, which, by weight, comprised: the compositions shown in Table 4, 5 parts glycerin, 6 parts squalane, 4 parts caprylic / capric triglycerides, 2 parts jojoba oil, 1.5 parts cetearyl oleate, 0.5 parts sorbitan oleate, 0.5 parts phenoxyethanol, and the balance being deionized water, totaling 100 parts.

[0073] The method for preparing the emulsion includes the following steps:

[0074] (1) Preparation of oil phase: Take a clean container, add squalane, caprylic / capric triglyceride and jojoba oil, stir well to form an oil phase solution, and set aside.

[0075] (2) Preparation of active aqueous solution: Add deionized water to another clean container, turn on the stirrer and set the speed to 500 rpm. First add glycerol, then add the extract of *Cymbidium goeringii* and the extract of *Sophora japonica*, stir for 15 minutes until fully dissolved, then slowly add theanine and stir for 5 minutes to ensure that all components are fully dissolved and homogeneous, thus obtaining the active aqueous solution for later use.

[0076] (3) Heating: Place the aqueous solution and the oil solution in a water bath and heat to 75°C. Maintain the temperature for 15 minutes to allow the components to dissolve and mix evenly.

[0077] (4) Emulsification: Homogenize at a speed of 2500 rpm, slowly pour the oil phase solution into the aqueous phase solution, and continue stirring for 30 minutes to fully emulsify the oil and water phases and form a primary emulsion.

[0078] (5) Cooling: Stop heating and let the primary emulsion cool naturally to 45°C. During this time, keep stirring and adjust the speed to 800 rpm.

[0079] (6) Add other ingredients: When the emulsion temperature drops to 45°C, add phenoxyethanol and continue stirring for 12 minutes.

[0080] (7) Homogenization: The cooled emulsion is transferred to a homogenizer and homogenized three times at a pressure of 12 MPa. The homogenization speed is 2000 rpm.

[0081] (8) Settling and Testing: Transfer the prepared emulsion to a clean container and let it stand for 18 hours. Observe whether the emulsion shows signs of stratification or demulsification. At the same time, perform relevant quality tests such as pH value and microbial content to ensure that the product meets quality standards.

[0082] (9) Packaging: After passing the inspection, the emulsion is dispensed into clean, sterile packaging containers, sealed, and stored to obtain the emulsion. The emulsion product prepared in Example 1 is as follows... Figure 1 As shown.

[0083] Whitening and anti-wrinkle efficacy test

[0084] Test samples: Emulsions were prepared from the compositions of Examples 1-14 and Comparative Examples 1-17.

[0085] Testing Methods: 155 volunteers aged 35-50 were selected and divided into 31 groups of 5 people each. All volunteers were women with sensitive skin. Sensitive skin was defined as occasional redness or brief stinging occurring ≥2 times per week based on self-assessment, and having whitening and anti-wrinkle needs. Each example test involved 5 participants, and each comparative test involved 5 participants. The test subjects applied the product twice daily, morning and evening, after cleansing, for 4 consecutive weeks. At weeks 2 and 4, a questionnaire was used to investigate the effectiveness and irritation of the product. The effectiveness criteria are shown in Table 5, and the effectiveness results are shown in Table 6.

[0086] Table 5

[0087]

[0088] Table 6

[0089]

[0090]

[0091] The results show that the combination of theanine, Sophora japonica fruit extract and Cymbidium goeringii extract in this invention has a synergistic effect and excellent whitening and anti-wrinkle effects.

[0092] Compared to Example 1, when the composition contained only theanine, only Sophora japonica fruit extract, or only Cymbidium goeringii extract, the prepared emulsion had no whitening or anti-wrinkle effect (Comparative Examples 1-3). Similarly, when the composition contained only theanine and Sophora japonica fruit extract, only Sophora japonica fruit extract and Cymbidium goeringii extract, or only theanine and Cymbidium goeringii extract, the prepared emulsion also had no whitening or anti-wrinkle effect (Comparative Examples 4-6). When the composition contained excessive amounts of theanine, Sophora japonica fruit extract, or Cymbidium goeringii extract, the prepared emulsion had a moderate or even almost no whitening or anti-wrinkle effect (Comparative Examples 7-9). When the composition contained insufficient amounts of theanine, Sophora japonica fruit extract, or Cymbidium goeringii extract, the prepared emulsion had a moderate or even almost no whitening or anti-wrinkle effect (Comparative Examples 10-12). When a component in the composition was replaced with a component having whitening and antioxidant effects, such as tea extract, tea polyphenols, bitter orange extract, or orchid extract, the prepared emulsion had a moderate or even almost no whitening or anti-wrinkle effect (Comparative Examples 13-16). When crude extract of Sophora japonica fruit is used instead of extract of Sophora japonica fruit, the whitening and anti-wrinkle effects of the prepared emulsion are not as good as those of the Sophora japonica fruit extract of the present invention (Comparative Example 17).

[0093] Furthermore, the crude extract of Sophora japonica fruit was purified using macroporous adsorption resin. By selecting appropriate resins and purification conditions, alkaloids in the Sophora japonica fruit extract could be effectively removed while retaining active ingredients such as polysaccharides and amino acids. Emulsions prepared using AB-8, D101, and NKA-9 macroporous adsorption resins showed good whitening and anti-wrinkle effects, with AB-8 and D101 resins showing superior results. This is likely because NKA-9 resin adsorbed some active ingredients from the Sophora japonica fruit extract during purification, resulting in lower whitening and anti-wrinkle efficacy compared to AB-8 and D101 resins (Examples 1, 6, and 11). The eluent used in the purification process was an aqueous solution containing ethanol and hydrochloric acid, with ethanol comprising 30-65% by volume and hydrochloric acid comprising 0.5-2% by mass. The Sophora japonica fruit extract obtained after elution was applied to the composition, resulting in an emulsion with good whitening and anti-wrinkle effects. The effect is better when using an eluent with 45-55% ethanol by volume and 0.8-1.2% hydrochloric acid by mass volume. This is likely because too little ethanol and hydrochloric acid in the eluent will lead to insufficient elution, while too much ethanol and hydrochloric acid will damage the active ingredients in the Sophora japonica fruit extract (Examples 1, 13, and 14).

[0094] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
