Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, specifically to a foundation containing moonflower white tea extract, its preparation method, and its application. Background Technology

[0002] Foundation is a core category of facial makeup, its core functions being to conceal skin imperfections, even out skin tone, and improve the appearance and texture of the skin. In recent years, with the development of cosmetic formulation technology, skin-nourishing foundations that combine makeup enhancement with skincare benefits have become a key research focus in this field. Among them, active extracts derived from natural plants are widely used in the formulation development of skin-nourishing foundations due to their good biocompatibility and gentle effects; white tea extract, rich in active substances such as tea polyphenols, possesses antioxidant and soothing skincare effects and has been publicly used in various skincare and makeup products, providing a technological foundation for the development of plant-based skin-nourishing foundations.

[0003] However, existing foundation technologies containing white tea extract still suffer from several unavoidable technical flaws: First, most existing solutions directly add ordinary white tea extract to the formula without optimizing the raw material compatibility based on the active ingredient characteristics of Moonlight White Tea. Furthermore, the preparation process of the extract lacks clear and precise limitations, resulting in low extraction rates of active ingredients, poor dispersibility and compatibility in the foundation's water-oil system, and an inability to effectively exert skincare activity. Additionally, there is a problem with the active ingredients being easily deactivated and degraded. Second, existing skincare-oriented foundations generally suffer from the technical contradiction of balancing corrective and skincare properties. To improve skincare efficacy... Reducing the amount of powder and film-forming agent can lead to a decrease in the product's coverage and makeup-holding performance, and can easily cause powder agglomeration and insufficient makeup longevity. Increasing the amount of powder and synthetic oil to ensure the corrective properties can increase the burden on the skin, easily causing skin irritation, clogged pores, and other problems, thus limiting the range of skin types it is suitable for. Third, existing technologies have not developed suitable preparation processes for foundation systems containing moonflower white tea extract, which can easily lead to uneven dispersion of the extract and poor product system stability. During long-term storage, phenomena such as layering, water separation, and powder sedimentation may occur, which cannot meet the quality stability requirements of cosmetics.

[0004] Therefore, there is an urgent need in this field to develop a foundation containing moonflower white tea extract that combines excellent makeup performance and skincare benefits, along with a matching preparation method, to solve the technical problems of insufficient efficacy of active ingredients, difficulty in balancing makeup performance and skincare benefits, and poor product system stability in existing technologies, and to meet the needs of this field for the research and development and industrial application of safe, stable, and multifunctional base makeup products. Summary of the Invention

[0005] The purpose of this invention is to provide a foundation containing moonflower white tea extract, its preparation method, and its application, so as to solve the problems existing in the prior art mentioned in the background art.

[0025] The method for preparing a foundation containing moonflower white tea extract according to any one of the claims includes the following steps:

[0026] S1) Add the humectant to deionized water, heat and stir until completely dissolved to obtain an aqueous phase material;

[0027] S2) Mix moisturizing oils, film-forming agents, and antioxidants, and heat and stir until completely dissolved to obtain an oil phase material;

[0028] S3) Add concealer and skin feel modifier to the oil phase material and disperse at high speed until the powder is free of agglomeration and completely wetted to obtain a powder dispersion.

[0029] S4) Heat the aqueous phase material to the same temperature as the powder dispersion and add it to it, then homogenize and emulsify to obtain the emulsified base material;

[0030] S5) After cooling the emulsified base material, add the moonlight white tea powder and concentrated extract of astragalus, preservatives, stir evenly, degas under vacuum, and discharge to obtain the flawless skin-nourishing foundation.

[0031] According to any one of the claims, the foundation containing moonflower white tea extract is used in the preparation of base makeup cosmetics to cover skin blemishes, blur pores, even out skin tone, and achieve a long-lasting, flawless makeup effect. At the same time, the concentrated extracts of moonflower white tea and astragalus in the foundation achieve skin-nourishing effects such as soothing repair, anti-oxidation, and brightening of skin tone.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1) This application uses a blend of Moonlight White Tea loose powder and Astragalus membranaceus concentrated extract as the core active ingredients. The two ingredients work synergistically to exert skin care effects such as anti-oxidation, soothing and repair, and brightening skin tone, while reducing the irritation of base makeup products to the skin. At the same time, through precise optimization of the ratio of functional components such as concealing and modifying powder, film-forming agent, and moisturizing oil, it achieves the modifying effect of covering skin blemishes, blurring pores, evening skin tone, and long-lasting makeup, thus solving the technical contradiction in the prior art that it is difficult to balance the modifying performance and skin care performance.

[0034] 2) This application can select an appropriate extraction method according to the type of target active ingredient, maximize the retention of water-soluble and fat-soluble active ingredients in the raw materials, ensure the skin care activity of the extract, and at the same time improve the compatibility and dispersibility of the extract in the water-oil system of foundation through the adaptation and optimization of the formulation system, effectively reduce the inactivation and degradation of active ingredients, and simultaneously improve the long-term storage stability of the product system.

[0042] Please see Figure 1 This invention provides a technical solution: a foundation containing moonshine white tea extract, comprising the following components by weight percentage:

[0043] 0.5%–5% of Moonlight White Tea loose material and Astragalus membranaceus blended concentrated extract;

[0044] 10%–30% concealing and correcting powder;

[0045] 1%–8% film-forming agent;

[0046] 5%–20% moisturizing oil;

[0047] 2% to 10% humectant;

[0048] 2% to 10% skin feel modifier;

[0049] 0.1% to 1% antioxidant;

[0050] 0.2% to 1% preservative;

[0051] The remainder is deionized water.

[0052] Specifically, this application provides a complete, stable, and industrially feasible foundation base formula that achieves a balance in terms of coverage, makeup longevity, skin feel, skin care, and stability. The formula uses a blend of moonflower white tea and astragalus extracts as its core active ingredients, ensuring an effective skin-care concentration without disrupting the overall foundation system. Concealing powders, film-forming agents, moisturizing oils, humectants, and skin feel modifiers work synergistically in proportion to achieve natural coverage, even skin tone, and long-lasting adherence, while ensuring a lightweight, non-greasy, non-caking, and non-drying finish. The addition of antioxidants and preservatives further enhances the product's storage stability and safety.

[0053] Specifically, the formula incorporates 0.5%–5% of loose moonflower white tea extract and concentrated astragalus extract, ensuring the effective concentration of core skin-nourishing active ingredients to fully exert their soothing, repairing, antioxidant, and brightening effects, while avoiding the negative impact of excessive amounts on the stability of the foundation's water-oil system and the longevity of the makeup. The 10%–30% concealing and correcting powder ratio precisely balances concealing power and natural makeup finish, effectively covering and softening blemishes, redness, and pores, while avoiding the heavy, cakey, and suffocating problems caused by excessive powder. The 1%–8% film-forming agent and 5%–20% moisturizing oil ratio work synergistically to achieve both long-lasting makeup and a comfortable feel on the skin. The balance of ingredients ensures the foundation's long-lasting wear, resistance to water and sweat, and prevents it from fading. Moisturizing oils alleviate the dryness and tightness caused by the film formation, while providing a compatible dispersion environment for the plant-based active ingredients. The 2%–10% moisturizer and 2%–10% skin feel modifier further optimize the product's feel on the skin and its long-term comfort, making it suitable for various skin types, including dry and oily skin. The combination of 0.1%–1% antioxidant, 0.2%–1% preservative, and the remainder deionized water ensures the product's long-term storage stability and achieves a gentle, non-irritating formula, significantly reducing the risk of skin irritation from foundation products.

[0054] The blended concentrated extract is prepared by mixing loose Moonlight White Tea leaves and Astragalus membranaceus at a mass ratio of 3:1 to 1:1. The effective components are extracted from the mixture using water extraction or water-alcohol extraction, followed by concentration and drying. Among these components:

[0055] Water extraction is suitable for extracting water-soluble active ingredients;

[0056] Water-alcohol extraction is suitable for the synergistic extraction of water-soluble and fat-soluble active ingredients.

[0057] Specifically, mixing Moonlight White Tea and Astragalus in a 3:1 to 1:1 ratio before extraction allows for the simultaneous dissolution of the active ingredients from both raw materials, resulting in a synergistic effect. The antioxidant and soothing effects are significantly superior to those of single extracts. Furthermore, clarifying the applicable targets for water extraction and hydroalcohol extraction allows for the selection of a more suitable process based on the type of target active ingredient. This approach efficiently extracts both water-soluble and fat-soluble components, improving extract utilization and efficacy integrity. The blended extract, obtained through concentration and drying, has high purity and few impurities. It is less prone to separation and deactivation in foundation, ensuring long-term stable skin-nourishing effects.

[0058] Specifically, within this ratio range, the active ingredients such as tea polyphenols in Moonlight White Tea and the active ingredients such as astragalus polysaccharides and astragalus saponins in Astragalus can achieve maximum synergistic effects. Compared with single Moonlight White Tea extract, the antioxidant and soothing repair effects of the two are significantly improved after combination, while avoiding the negative effects on the color and aroma of the formula caused by excessive addition of Astragalus. Secondly, the process of mixing the two raw materials to form a mixed raw material before extraction, compared with the method of extracting the two raw materials separately and then combining them, allows for simultaneous dissolution of active ingredients, further strengthening the synergistic effect of the two, while simplifying the extraction process and making it more suitable for industrial-scale production.

[0059] The concealing and correcting powder is selected from one or more of titanium dioxide, zinc oxide, silica, nylon-12, polymethyl methacrylate microspheres, and mica. Specifically, the powders selected in this application are all compliant and stable commonly used raw materials in the cosmetics field. Through the combination of various powders with different structures and functions, multiple optimizations are achieved in terms of concealing power, natural makeup effect, and smooth skin feel, solving the technical problem of difficulty in achieving both concealing effect and skin feel in the application of a single powder in existing foundations. Titanium dioxide and zinc oxide, as inorganic concealing powders, possess excellent coverage and UV protection capabilities, effectively concealing skin blemishes such as pigmentation and redness, while also providing additional sun protection. Silica, nylon-12, and polymethyl methacrylate microbeads, as spherical functional powders, have excellent light scattering effects, which can conceal pores and smooth skin texture through soft-focus optical effects, while reducing the cohesion between powders, improving the smoothness of foundation application, and avoiding problems such as caking and pilling. Mica, as a flake-like powder, can give the foundation a natural skin glow, avoiding the mask-like and whitening problems caused by inorganic concealing powders, making the makeup effect more in line with the natural skin texture. This limited edition, through the flexible blending of different powders, can adapt to different makeup effect needs such as high coverage and light nude makeup. At the same time, all powders have excellent chemical stability and good compatibility with film-forming agents, moisturizing oils and skin feel modifiers in the formula. They can be evenly dispersed in the oil phase, further improving the long-term storage stability of the foundation system and avoiding problems such as powder sedimentation and agglomeration.

[0060] The film-forming agent is selected from one or more combinations of acrylic (ester) copolymers, VP / hexadecene copolymers, and trimethylsiloxysilicates;

[0061] The moisturizing oil is selected from one or more of squalane, jojoba seed oil, caprylic / capric triglyceride, and polydimethylsiloxane.

[0062] Specifically, acrylic (ester) copolymers, VP / hexadecene copolymers, and trimethylsiloxysilicates are all high-performance film-forming raw materials in the color cosmetics field. Among them, acrylic (ester) copolymers have excellent water and sweat resistance, and can form a uniform, flexible, and dense film on the skin surface, fixing powder for a long time and preventing makeup from fading or becoming patchy. VP / hexadecene copolymers have good skin adhesion and flexibility, and do not feel tight after film formation, making them suitable for sensitive skin and other delicate skin types. Trimethylsiloxysilicates, as an organosilicon film-forming agent, have excellent smoothness and anti-transfer properties, which can prevent foundation from smudging or sticking to masks, while improving the dry and refreshing feel of the product.

[0063] Specifically, the four types of moisturizing oils—squalane, jojoba seed oil, caprylic / capric triglycerides, and dimethicone—cover three major categories: synthetic oils, plant oils, and silicone oils. Among them, squalane and jojoba seed oil have structures similar to human sebum, possessing excellent skin affinity and repairing effects, which can alleviate the irritation of foundation to the skin barrier. Caprylic / capric triglycerides have good moisturizing and solubility, which can fully dissolve oil-soluble active ingredients and film-forming agents in the formula, improving system compatibility. Dimethicone can give the foundation a smooth spreadability, reduce the friction between powders, and avoid caking and a heavy feeling. The synergistic selection of film-forming agents and moisturizing oils allows the film-forming agent to form a film and maintain makeup while the moisturizing oils alleviate the dryness caused by the film formation. At the same time, the moisturizing oils can improve the evenness of the film-forming agent on the skin surface, making the film more continuous and adherent, further enhancing the makeup-holding effect. In addition, the two together construct the oil phase system of the foundation, providing a stable dispersion environment for the core plant extracts and oil-soluble antioxidants, thus improving the stability of the entire formula system.

[0064] The moisturizers are selected from one or more combinations of sodium hyaluronate, glycerin, propylene glycol, panthenol, and ceramides. Specifically, the selected moisturizers cover three main categories: humectant moisturizers, water-locking moisturizers, and repairing moisturizers. Through the combination of moisturizers with different mechanisms of action, a multi-layered moisturizing system is constructed, fundamentally solving the problems of dryness, caking, and powderiness when applying foundation, while further enhancing the product's skin-nourishing effects. The selected glycerin and propylene glycol, as classic humectants, can draw moisture from the environment and the skin's stratum corneum, providing immediate hydration and enhancing the foundation's antifreeze properties and storage stability. Sodium hyaluronate, as a macromolecular water-locking humectant, forms a moisturizing film on the skin's surface, locking in moisture for a long time and preventing water loss. It also reduces friction and irritation from the powder, improving smoothness upon application. Panthenol and ceramides, as repairing humectants, penetrate the stratum corneum, repairing the skin barrier and enhancing the skin's own water-locking ability. They also have excellent soothing properties, relieving skin irritation caused by makeup products. Together with the core concentrated extracts of moonflower white tea and astragalus, they create a synergistic effect, further strengthening the product's skin-nourishing and repairing efficacy. Therefore, by combining moisturizers with different mechanisms of action, flexible formulations can be made according to the needs of different skin types. This can provide long-lasting moisturizing effects for dry skin, preventing caking and dryness in autumn and winter. Alternatively, a low-ratio, refreshing moisturizer can be used to suit the needs of oily skin, avoiding stickiness and oiliness. At the same time, all moisturizers have excellent water solubility and can be completely dissolved in the aqueous phase, improving the stability of the water phase system of the foundation and avoiding the problems of water phase precipitation and separation. They also form a water-oil synergistic moisturizing system with the moisturizing oils in the oil phase, achieving an immediate moisturizing effect upon application and a long-lasting, non-drying effect.

[0065] The skin feel modifier is selected from one or more of the following: spherical silica microparticles, polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymers, and kaolin. Specifically, the selected skin feel modifiers are all functional raw materials commonly used in the color cosmetics industry. By combining skin feel modifiers with different mechanisms of action, the overall skin feel, makeup staying power, and makeup texture of the foundation are comprehensively optimized, solving the technical problems of existing foundations such as heavy, cakey appearance, pilling, insufficient oil control, and patchiness. The selected spherical silica micropowder, as a spherical porous powder, possesses excellent oil-control and absorption capabilities. It can effectively absorb excess oil secreted by the skin, preventing issues such as oiliness, makeup slippage, and patchiness during makeup application. At the same time, its spherical structure reduces friction between powder particles, improving the smoothness of foundation application and achieving a silky feel on the skin. Polydimethylsiloxane / vinyldimethylsiloxane cross-linked polymer, as an organosilicon elastomer, has excellent pore-filling and texture-smoothing effects. It can physically fill in and conceal pores and fine lines, while giving the foundation a soft, silky feel, avoiding the dryness and heaviness of powder, and enhancing the soft-focus naturalness of the makeup effect. Kaolin, as a natural mineral powder, has gentle oil-control and astringent properties, ensuring long-lasting makeup and improving the adhesion of powder to the skin surface, preventing foundation shifting and makeup slippage. This limited edition allows for flexible blending of different functional skin feel modifiers to suit various skin feel and makeup longevity needs. A high proportion of oil-controlling skin feel modifiers can be used to suit oily skin and summer makeup longevity needs, while a low proportion of smoothing skin feel modifiers can be used to suit dry skin and autumn / winter moisturizing needs. At the same time, skin feel modifiers can work synergistically with concealer and corrective powders to optimize powder dispersion, prevent powder agglomeration and sedimentation, further improve the storage stability of the foundation system, and reduce powder irritation to the skin, achieving a refreshing, non-greasy, smooth, and non-caking application effect.

[0066] The antioxidant is selected from one or a combination of two of tocopherol and ascorbate tetraisopalmitate; the preservative is selected from one or a combination of more than two of phenoxyethanol, ethylhexylglycerin, and p-hydroxyacetophenone. Specifically, this application selects antioxidants and preservatives in a gentle and efficient manner, ensuring product safety and stability while further enhancing the antioxidant and skin-nourishing properties of the foundation. This not only guarantees the long-term storage stability and safety of the foundation product but also further enhances its antioxidant makeup-holding effect and gentle skin-nourishing characteristics, solving the technical problems of existing foundations such as easy darkening after makeup wear, highly irritating preservative systems, and poor compatibility with active ingredients. The selected tocopherol and ascorbate tetraisopalmitate are both oil-soluble antioxidants with excellent compatibility with the oil phase system of the foundation. They can be fully dispersed in the formula system, which can inhibit the oxidative rancidity of oils and active ingredients in the formula, extend the shelf life of the product, and ensure the quality stability of the product during storage. On the other hand, they can play an antioxidant role on the skin surface to fight free radicals in the environment. Together with the core concentrated extracts of moonflower white tea and astragalus, they form a synergistic antioxidant system to prevent the makeup from becoming dull and yellow due to sebum oxidation during makeup wear, and maintain the clean and bright makeup for a long time, achieving the effect of makeup that does not become dull. The selected phenoxyethanol, ethylhexylglycerin, and p-hydroxyacetophenone are all mild preservatives widely used in the cosmetics industry. They are formaldehyde-free, have extremely low skin irritation, and are suitable for sensitive skin and other delicate skin types. They also possess broad-spectrum antibacterial effects, effectively inhibiting the growth and reproduction of bacteria, mold, and other microorganisms, ensuring the product's microbial safety during opening and use. Furthermore, these preservatives have excellent compatibility with the plant-based active ingredients and functional components in the formula, and will not react with the core active ingredients to cause inactivation, nor will they affect the stability and makeup effect of the foundation. The synergistic selection of antioxidants and preservatives creates a dual guarantee system of antioxidant stability and mild preservatives. This ensures the product's quality stability and safety from the source, further enhances its antioxidant and skin-nourishing effects and makeup lasting radiance, while avoiding the skin irritation problems associated with traditional preservative and antioxidant systems.

[0067] According to another aspect of this application, a method for preparing a foundation containing moonflower white tea extract is also provided, comprising the following steps:

[0068] S1) Add the humectant to deionized water, heat and stir until completely dissolved to obtain an aqueous phase material;

[0069] S2) Mix moisturizing oils, film-forming agents, and antioxidants, and heat and stir until completely dissolved to obtain an oil phase material;

[0070] S3) Add concealer and skin feel modifier to the oil phase material and disperse at high speed until the powder is free of agglomeration and completely wetted to obtain a powder dispersion.

[0071] S4) Heat the aqueous phase material to the same temperature as the powder dispersion and add it to it, then homogenize and emulsify to obtain the emulsified base material;

[0072] S5) After cooling the emulsified base material, add the moonlight white tea powder and concentrated extract of astragalus, preservatives, stir evenly, degas under vacuum and discharge the material to obtain the flawless skin-nourishing foundation.

[0073] Specifically, in the preparation process of this application, the aqueous phase and oil phase materials are prepared in steps. The water-soluble moisturizer is dissolved in deionized water by heating, and the oil-soluble emollients, film-forming agents, and antioxidants are mixed and dissolved by heating. This ensures that the water-soluble and oil-soluble components are completely dissolved separately, avoiding problems such as system instability and crystallization caused by incomplete dissolution. Secondly, the concealing and correcting powder and skin feel modifier are added to the oil phase material for high-speed dispersion. Compared to the traditional process of adding powder to the aqueous phase, oil phase dispersion can fully wet the powder surface, reduce the surface energy of the powder, prevent powder agglomeration and sedimentation, and achieve uniform dispersion of the powder. This ensures the concealing power and smooth skin feel of the foundation, avoiding issues such as caking and graininess. Secondly, heating the aqueous phase material to the same temperature as the powder dispersion before homogenization and emulsification avoids problems such as emulsion breakdown and coarse particles caused by excessive temperature difference between the two phases. Homogenization and emulsification form a uniform and delicate oil-in-water emulsion system, ensuring the long-term storage stability of the product and avoiding stratification and water separation. Finally, cooling the emulsion base before adding the core Moonlight White Tea and Astragalus blended concentrated extracts and preservatives avoids the destruction of heat-sensitive active ingredients in plants by high-temperature processes, maximizing the preservation of the skincare efficacy of the core active ingredients, and avoiding the volatilization and deactivation of preservatives caused by high temperatures. Vacuum degassing removes air bubbles from the system, ensuring the product's delicate texture and uniform appearance. The entire preparation process has clear steps and controllable parameters, requiring no special production equipment and can be directly adapted to industrial-scale production in the cosmetics industry. The resulting product has good batch-to-batch quality stability, high retention rate of active ingredients, and a uniform and stable system. Long-term storage does not result in stratification, water separation, or powder sedimentation, while fully ensuring the realization of the makeup and skincare effects designed in the formula.

[0074] According to another aspect of this application, the application of a foundation containing moonflower white tea extract in the preparation of base makeup cosmetics is also provided. The base makeup cosmetics are used to cover skin blemishes, blur pores, even out skin tone, and achieve a long-lasting, flawless makeup effect. At the same time, the concentrated extracts of moonflower white tea and astragalus in the foundation achieve skin-nourishing effects such as soothing repair, anti-oxidation, and brightening of skin tone.
