Description

Technical Field

[0001] The present application relates to the technical field of cosmetic raw materials, and more particularly to a preparation method and application of a long-lasting makeup powder. Background Art

[0002] In the field of cosmetic raw materials, long-lasting makeup powder has always been the focus of attention of consumers and R&D personnel. Long-lasting makeup powder needs to have good hardness and softness, and be able to be tightly and durably adsorbed and combined with the skin surface to cope with various situations that may occur in daily activities, such as sweating, oil production, etc., so as to maintain the integrity and beauty of the makeup.

[0003] At present, some related technologies have attempted to improve the makeup-lasting performance of powders. For example, CN118512357A discloses a technical solution of simply mixing a polyvinyl pyrrolidone film-forming agent with oil, powder, pigment, emulsifier, etc. This simple mixing method improves the hardness and softness of the formula to a certain extent, so that the powder can be better adsorbed and bound to the skin surface. However, this technology has obvious defects. The film-forming agent and the powder are only in a physical mixing state. The film-forming agent fails to form a uniform, complete and dense coating layer on the powder surface, and powder cross-linking cannot be achieved. This makes it difficult for the powder to achieve a long-lasting makeup effect during actual use, and cannot effectively meet consumers' demand for long-lasting makeup.

[0004] In addition, CN114224747B proposes another technical idea, which is to surface treat the color powder with film-forming agents such as trimethylsiloxysilicate. After this treatment, the color powder has good film-forming properties and hydrophobicity, effectively improving its dispersion and compatibility problems in the product formula, and can combat the situation of excessive oil production on the skin, and to a certain extent achieve long-lasting makeup. However, this method uses dry coating technology and only coats a layer of film-forming agent on the surface of the color powder. This treatment method causes the powder to become dry and tight after being applied to the face. For people with dry skin, the user experience is extremely poor, which greatly limits the product's scope of application and user experience.

[0005] In summary, the existing long-lasting makeup powder preparation technologies all have deficiencies to varying degrees, and are unable to simultaneously take into account long-lasting makeup effects and good skin feel, and cannot meet the diverse needs of consumers with different skin types. Therefore, it is of great practical significance to develop a long-lasting makeup powder preparation method that can achieve long-lasting makeup, is suitable for a variety of skin types, and brings a good user experience. Summary of the Invention

[0006] In order to improve the problems of drying out and incomplete hydrophobicity caused by modifying the base powder with different film-forming agents, the present application provides a preparation method and application of a long-lasting makeup powder.

[0007] In the first aspect, the present application provides a method for preparing a long-lasting makeup powder using the following technical solution: A method for preparing a long-lasting makeup powder comprises the following steps: providing a base powder; stirring and mixing the base powder with an aqueous component to completely wet the powder to obtain a semi-wet mixture; stirring and mixing the semi-wet mixture again with a solution containing a film-forming agent; and drying and airflow-pulverizing the mixture to obtain the powder.

[0008] Furthermore, the particle size of the base powder is 20-15000 nm.

[0009] Furthermore, the mass fraction of the aqueous component is 5-10%.

[0010] Furthermore, the viscosity of the solution containing the film-forming agent is 5 mPa·s-600 mPa·s.

[0011] Furthermore, the solvent of the film-forming agent solution is volatile oil, the mass fraction of the film-forming agent is 30%-60%, and the mass of the film-forming agent solution is 3%-6% of the mass of the base powder.

[0012] Optionally, the aqueous component includes at least one of deionized water, glycerol, butylene glycol, propylene glycol, polyglycerol-3, polyglycerol-6, polyglycerol-10, hyaluronic acid, sodium hyaluronate, potassium hyaluronate, sodium hyaluronate cross-polymer, acetylated sodium hyaluronate, sorbitol, sorbitol polyether 20, sodium polyglutamate, and niacinamide.

[0013] Optionally, the film-forming agent includes at least one of trimethylsiloxysilicate, trimethylsiloxysilylcarbamoyl pullulan, hydroxypropyl starch, polyvinyl pyrrolidone, polyvinyl alcohol, acrylic resins, polyurethanes, silicone resins and silica sol / silicone composite materials.

[0014] Optionally, the solvent of the solution containing the film-forming agent includes at least one of an isoparaffin solvent or a volatile silicone oil solvent.

[0016] In the second aspect, the application of a long-lasting makeup powder provided in this application adopts the following technical solution: the application of the powder prepared by the above-mentioned preparation method of the long-lasting makeup powder in liquid foundation.

[0017] In summary, this application has the following beneficial effects: 1. This application utilizes a unique two-step preparation method. The first step involves wetting the powder with an aqueous solution containing a moisturizer to break up hard agglomerates, improve dispersibility, and enhance reactivity, thereby increasing the probability of film-forming agent coating. The moisturizing ingredients also alleviate dryness and tightness. The second step involves evenly coating the powder with a film-forming dispersant. Through physical adsorption and chemical condensation reactions, a stable coating is formed, achieving cross-linking of the powder film. This imparts waterproof, anti-sebum, and long-lasting properties to the powder. Furthermore, during the drying process, the moisturizing ingredients are firmly coated, improving the powder film's flexibility and brittleness. 2. The preparation method in this application not only broadens the application range of modified base powders, but also expands the application range of powders modified with film-forming agents. Various types of film-forming agents are applicable to this method, providing more options for different needs. 3. This application effectively improves the problems of drying out and incomplete hydrophobicity caused by the modification of base powders with different film-forming agents, so that the powder has better comprehensive performance, and provides an application solution for this long-lasting makeup powder in liquid foundation, promoting the application of this powder in the actual cosmetics field.

[0039] The powders prepared in Examples 1-9 and Comparative Examples 1-8 were subjected to contact angle tests on their surfaces using an optical contact angle tester; and hydrophobicity tests were performed. The obtained powders were mixed with isododecane in a ratio of 1:3, and then coated on a plate and air-dried to test the anti-sweat and anti-corrosion properties. The test results are shown in the table below.

[0040] From the above table data, it can be seen that the powders prepared by the methods provided in Examples 1-9 of this application have excellent hydrophobic properties, and their contact angles are all greater than 120°, successfully achieving a super-hydrophobic effect. This characteristic can be Figure 1 The hydrophobicity test graph of Red 28 Barium Lake corresponding to Example 2 in B and Figure 2 The titanium dioxide contact angle test graph corresponding to Example 8 in Figure B is visually presented. Specifically, the powders produced in these examples not only exhibit remarkable hydrophobicity, exhibiting excellent suspension properties by remaining stably suspended on the liquid surface without settling upon contact with liquids, but also possess excellent sweat resistance, remaining stable even in simulated sweat environments. More notably, these powders performed exceptionally well in sebum resistance testing, withstanding up to 200 drops of artificial sebum without slipping, fully demonstrating their robust resistance to sebum erosion.

[0041] In contrast, the powders prepared in Comparative Examples 1-8 do not have the above-mentioned excellent properties. Figure 1 The hydrophobicity test graph of Red 28 Barium Lake corresponding to Comparative Example 2 in A and Figure 2 The contact angle test graph for titanium dioxide corresponding to Comparative Example 4 shows this. The powders in these comparative examples rapidly absorbed the liquid and settled upon contact, demonstrating virtually no hydrophobicity. Furthermore, their performance in sweat and sebum resistance tests was equally disappointing, with no sweat resistance at all, and they slipped after just five drops of artificial sebum. This is likely due to the film-forming agent failing to successfully coat the powder, resulting in a high number of hydrophilic groups remaining on the powder surface.

[0042] In addition, the powders obtained in Example 9 and Comparative Example 4 were mixed with isododecane at a ratio of 1:3, and then coated on a plate and air-dried to test the bending flexibility. Figure 3 , where A1 is the flexibility test diagram of the titanium dioxide corresponding to Comparative Example 4 before bending, and A2 is the flexibility test diagram after bending; B1 is the flexibility test diagram of the titanium dioxide corresponding to Example 9 before bending, and B2 is the flexibility test diagram after bending; it can be seen that the powder obtained in Example 9 has good bending flexibility, while the powder obtained in Comparative Example 4 has a large difference before and after bending, and obvious cracks appear on the black and white card after bending.

[0043] Analyze the possible reasons: The preparation method of this application first adds an aqueous solution containing a moisturizing agent. The water molecules fully wet the powder, which can destroy the hard agglomeration of the dry powder, improve dispersibility, expose more active surfaces, regenerate surface hydroxyl groups, enhance reaction activity, and increase the probability of successful coating of the powder by the film-forming agent. On the other hand, moisturizing ingredients such as hyaluronic acid and propylene glycol provide the powder with a moist feel, improving the dryness and tightness caused by the film-forming agent in the later stage. Next, a film-forming agent and dispersant are used to evenly coat the powder. In liquid form, the film-forming agent is easier to mix evenly with the powder and is adsorbed on the powder surface through van der Waals forces to form a preliminary physical coating. Subsequently, under high-temperature drying conditions, the polymer is continuously concentrated due to the volatilization of the solvent, and the repulsive force between the polymer particles on the interface is overcome, allowing the film-forming agent particles to flow with each other, forming a uniform, continuous, closed, and stable film wrapped around the powder surface. In addition, the -OH groups on the surface of the color powder can undergo condensation reactions with the reactive groups of the film-forming agent (such as Si-O-Si) to form covalent bonds, enhancing the stability of the coating and reducing the risk of shedding. Ultimately, the powder film is cross-linked, giving the powder waterproof, anti-sebum, and long-lasting makeup properties; In addition, during the drying process after the base powder is processed, the organic solvent and water will gradually evaporate, causing the moisturizing components to precipitate from the water phase and deposit on the surface of the base powder, thereby achieving a firm coating of the moisturizing components on the surface of the base powder, further improving the problems of poor powder film flexibility and hard and brittle film formed by simple film-forming agent wrapping.

[0044] Application Examples A liquid foundation, its formula used is as follows: The powders in phase B are obtained from Example 1, Example 4, Example 5, and Example 6, and are composed in a mass ratio of 1:1:1:1; Above-mentioned liquid foundation is made by the following method: Add the raw materials of phase A into the beaker in sequence, heat to 80℃ in a water bath, and stir until dissolved; Add the raw materials of phase B to phase A in sequence and homogenize at high speed until the slurry and gel raw materials are completely dispersed to obtain the oil phase; Add the Phase C raw materials into another beaker, heat to 80°C in a water bath, and stir until completely dissolved to obtain the aqueous phase; Slowly and evenly add the aqueous phase to the oil phase. Stir and cool to 45°C. Add phase D and homogenize thoroughly at 10,000 rpm. Stir at medium speed for 2 minutes and discharge to obtain liquid foundation.

[0045] Thirty volunteers aged between 25 and 45 were selected as research subjects. After applying the liquid foundation prepared above, the volunteers' feedback was collected and recorded from three dimensions: moisturizing, tightness, and makeup durability (the evaluation levels were divided into "good", "medium", and "poor"). The specific statistical results are shown in the table below.

[0046] The data in the table above clearly demonstrates that the liquid foundation formulated based on the application examples exhibits excellent moisturizing properties, resulting in minimal skin tightness after application. Furthermore, the liquid foundation exhibits excellent sweat and sebum resistance, effectively ensuring the long-lasting appearance of the makeup, ensuring that it remains in good condition for a long time.

However, as long as they are within the scope of the claims of this application, they should be protected by patent law.
