Description

Technical Field

[0001] The present application relates to the technical field of cosmetics, and more specifically, to a morphologically transformable lip makeup product and a preparation method thereof. Background Art

[0002] Lip cosmetics meet different makeup needs by modifying lip shape, lip color and moisturizing. They are an important component of cosmetics and mainly include lipstick, lip gloss, lip balm, lip gloss, lip glaze and other products. The raw materials used include: colorants, fillers, waxes, esters, natural oils, hydrocarbons, active ingredients, etc.

[0003] When applying lip cosmetics, such as lipstick, because it is in stick form, it is easy to break during express delivery, making it unusable. In addition, in the high temperature environment of summer, the paste of lipstick is easy to melt, making the product unusable. For example, liquid lip gloss, most of the products on the market are full oil systems. This type of product is sticky and greasy during use, which makes the experience on the lips unpleasant. In addition, this type of liquid lip gloss is prone to leakage in the tube, causing consumers to easily leak it into their bags during storage, which makes the experience unpleasant. Therefore, powder-to-cream technology is used. Through a special formula, the powder is transformed into a cream after contact with the skin. This morphological change can overcome the application defects of the above-mentioned lipstick and liquid lip gloss, and is easy to store and transport.

[0004] Regarding the above-mentioned related technologies, the inventors believe that in the application process of powder-to-cream, the powder balance is mainly destroyed by applying pressure, and mechanical friction is used to fully mix the particles and the liquid matrix. Although it can be formed into a frosty state, it is often difficult to achieve a relatively uniform mixing effect of the various component raw materials in this process, which leads to the fact that the frosting effect still needs to be improved.

[0005] Therefore, it is urgent to propose a solution to solve the above technical problems. Summary of the Invention

[0006] In order to improve the mixing uniformity of various components in the powder-to-cream process when applying lip cosmetics, thereby achieving a better frosting effect, the present application provides a morphologically transformable lip cosmetic and a preparation method thereof.

[0007] In a first aspect, the present application provides a lip cosmetic product that transforms into a lip shape, using the following technical solution: A morphologically transformable lip cosmetic is prepared from the following raw materials in parts by weight: Functional powder A 15-30 parts; 10-20 parts of functional powder B; 7.5-15 parts of coordination auxiliary agent; 10-20 parts of vinyl dimethicone / methicone silsesquioxane crosspolymer; 2.5-5 parts of boron nitride; Colorant 21.5-43 parts; 2.5-5 parts of emulsifier; Phytosteryl oleate & phytosterols 2.5-5 parts; 17.5-35 parts of moisturizer; 30-60 parts of solvent; 6.5-13 parts of skin conditioning agent; 20-40 parts of film-forming agent; The functional powder A is composed of mica, perlite and silica; The functional powder B is composed of polymethylsilsesquioxane and polymethyl methacrylate cross-linked polymer; The coordination auxiliary agent consists of silica silylate and octyl polymethylsiloxane.

[0008] By adopting the above technical solution, the morphological transformation lip cosmetics are in a dry powdery state when static, and can be applied with a brush, and transformed into a smooth creamy state by applying between the brush and the lips. Among the raw materials for the preparation of the morphological transformation lip cosmetics, functional powder A is composed of mica, perlite and silica, which can form a loose porous structure under static conditions, not only giving the product a powdery texture, but also providing a basic skeleton, and maintaining the looseness of the powder after adsorbing oily ingredients; functional powder B is composed of polymethylsilsesquioxane and polymethyl methacrylate cross-linked polymer, which can enhance the powder fluidity and reduce agglomeration through low-density microspheres to ensure free flow when static; the coordination aid is composed of silica silylate and octyl polymethylsiloxane, which mainly coats the powder surface to reduce water content. The powder has good affinity to ensure a dry appearance; a macro powder structure is formed by the cooperation between functional powder A, functional powder B and coordinating additives, the pores of which can store liquid ingredients, but the hydrophobic layer on the surface prevents seepage when static; when applied, mechanical pressure destroys the powder structure, releasing the liquid to form a smooth cream; at the same time, in the process of turning into cream, a pre-dispersed network can be built, which can not only quickly release the encapsulated liquid ingredients, but also achieve a more uniform mixing effect of the various component raw materials, thereby realizing the uniform fusion of the "water-oil-powder" three phases, and finally making the cream-forming effect better when applying the morphological transformation lip cosmetics.

[0009] Preferably, the functional powder A is composed of the following components in parts by weight: 10-20 parts of mica; 2.5-5 parts perlite; Silica 2.5-5 parts.

[0010] By adopting the above technical solution, mica is used as the core carrier, and its lamellar structure provides an extension base, reducing powder agglomeration, and high dosage ensures the formation of a continuous network to wrap other powders; perlite is used as a "liquid warehouse" to establish an effective liquid storage network, balance the system density, prevent sedimentation, and ensure powder fluidity; silica fills the gap between mica and perlite, reduces the interface porosity, promotes the "water-oil-powder" three-phase fusion, and brings about improved ductility; and the above-mentioned amounts of mica, perlite and silica, when used in combination, can optimize the stacking density, and in the process of powder-to-cream transformation of lip cosmetics, can achieve the free flow and dynamic and uniform release of each component raw material, thereby obtaining a better frosting effect.

[0011] Preferably, the functional powder B is composed of the following components in parts by weight: 5-10 parts of polymethylsilsesquioxane; 5-10 parts of polymethyl methacrylate cross-linked polymer.

[0012] By adopting the above technical solution, polymethylsilsesquioxane is used as spherical microspheres, and its low surface energy characteristics reduce friction between particles and promote free flow; the hard microspheres of polymethyl methacrylate cross-linked polymer prevent lightweight powder from scattering through mechanical interlocking, and the two form a complementary gradation; at the same time, the cooperation between the two can not only synergistically construct a continuous frosting film, but also make the frosting both ductile and formable, thereby achieving a better frosting effect.

[0013] Preferably, the coordination aid is composed of the following components in parts by weight: 5-10 parts of silica silylate; 2.5-5 parts of octyl polymethylsiloxane.

[0014] By adopting the above technical solution, silica silylate can inhibit the agglomeration caused by van der Waals forces between powders and prevent powder density imbalance caused by excessive coating; octyl polymethylsiloxane, with its extremely low viscosity, penetrates the gaps between powders to form a pre-wetting layer; at the same time, the combination of the two can form a "powder-oil" homogeneous dispersion system, which can also drive the rapid spreading and mixing of the raw materials when releasing the coated raw materials, achieving instantaneous homogeneous transformation of the powder and smooth skin-adherence of the cream, thereby achieving a better cream-forming effect.

[0015] Preferably, the colorant is composed of the following components in parts by weight: 2.5-5 parts of bismuth oxychloride; 2.5-5 parts of titanium dioxide; 2.5-5 parts of iron oxide yellow; 1-2 parts of red iron oxide; 0.5-1 part of black iron oxide; CI 15850 2.5-5 parts; CI 45410 2.5-5 parts; CI 19140 2.5-5 copies; CI 77360 2.5-5 parts; CI 15985 2.5-5 parts.

[0016] By adopting the above technical solution, the selection and combination of the above types of colorants can meet the application requirements of the form-changing lip cosmetics, and show strong compatibility and dispersibility with other raw materials, achieving the unity of high color rendering and strong stability, and obtaining form-changing lip cosmetics with excellent and stable application quality.

[0017] Preferably, the emulsifier is cyclopentasiloxane & PEG / PPG-18 / 18 polydimethylsiloxane.

[0018] By adopting the above technical solution, the above-mentioned emulsifier quickly reduces the interfacial tension under friction and promotes the mixing of oil and water. The cyclopentasiloxane it contains can quickly wet the gaps between powders, and the PEG / PPG-18 / 18 polydimethylsiloxane is directionally adsorbed on the surface of polar powders to form an amphiphilic coating layer and construct a three-dimensional network structure, which locks in moisture to form a continuous phase of cream, achieving a smooth transition from "powder to cream", thereby enabling the lip cosmetics with a better frosting effect when applied.

[0019] Preferably, the moisturizing agent is composed of the following components in parts by weight: 2.5-5 parts of propylene glycol; 5-10 parts of glycerin; 5-10 parts of butanediol; Caprylhydroxamic acid & 1,2-hexanediol & 1,3-propylene glycol 5-10 parts.

[0020] By adopting the above technical solution, the low viscosity characteristics of propylene glycol and butylene glycol can quickly wet solid powders and promote uniform dispersion; 1,3-propylene glycol and 1,2-hexanediol reduce the oil-water interfacial tension and assist in emulsification stability; caprylhydroxamic acid releases water-locking components when rubbed, and cooperates with glycerin to instantly form a moisturizing continuous phase, enhancing the smoothness of the "powder to cream" transition; therefore, the selection of the above moisturizers can achieve long-lasting hydration and efficient conversion when applying lip cosmetics that transform into a new shape, ultimately bringing about a better cream-forming effect.

[0021] Preferably, the skin conditioner is composed of the following components in parts by weight: 2.5-5 parts of panthenol; 0.5-1 part sodium hyaluronate; Ceramide 0.5-1 part; 1-2 parts Lactobacillus / Acerola Cherry Ferment & Leuconostoc / Radish (RAPHANUS SATIVUS) Root Ferment Filtrate; 1-2 parts of dipalmitoyl hydroxyproline, palmitic acid, and water; 1-2 parts of dipotassium glycyrrhizate.

[0022] By adopting the above technical solution, the use of the above skin conditioners can bring about a synergistic effect to optimize the "powder to cream" morphological conversion process, ensure the uniformity of the cream after conversion, obtain a better cream-forming effect, and at the same time enhance the moisturizing, repairing and anti-allergic properties.

[0023] Preferably, the film-forming agent is composed of the following components in parts by weight: 10-20 parts of acrylic acid (ester) copolymer; 10-20 parts of styrene / acrylic acid (ester) copolymer.

[0024] By adopting the above technical solution, the hydrophilic chain segments of the acrylic acid (ester) copolymer and the hydrophobic benzene rings of the styrene / acrylic acid (ester) copolymer work synergistically to effectively reduce the oil-water interfacial tension and ensure uniform dispersion during the "powder to cream" process; at the same time, they can cooperate with the emulsifier to form a continuous film and ensure the ductility of the formed cream; in this way, it can be ensured that the morphological transformation lip cosmetics have a better frosting effect when applied.

[0025] In a second aspect, the present application provides a method for preparing a morphologically transformable lip cosmetic, which adopts the following technical solution: A method for preparing a morphologically transformable lip cosmetic comprises the following steps: (1) preparing raw materials including functional powder A, functional powder B, a coordination aid, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-polymer, boron nitride, a colorant, an emulsifier, phytosteryl oleate & phytosterols, a moisturizer, a solvent, a skin conditioner, and a film-forming agent according to a ratio; (2) The functional powder A, functional powder B, silica silylate, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer, boron nitride and colorant in step (1) are stirred, mixed and crushed, and then the pre-mixed emulsifier, octyl polymethylsiloxane and phytosterol mixture in the coordination aid are added, and the mixture is stirred, mixed and crushed to obtain an intermediate product; (3) The moisturizing agent, solvent, skin conditioning agent and film-forming agent in step (1) are mixed evenly, and then mixed with the intermediate product obtained in step (2) and stirred, and then sieved to obtain the morphological transformation lip cosmetics.

[0026] By adopting the above technical solution, the above preparation method is simple to operate, and the raw materials are added and used in steps during the process, which not only facilitates quality control during the process, but also enables the raw materials to fully combine and interact with each other, thereby obtaining high-quality and stable morphological transformation lip cosmetics, and the whole is also suitable for large-scale industrial production.

[0027] In summary, this application has the following beneficial effects: The present application uses functional powder A composed of mica, perlite and silica, functional powder B composed of polymethylsilsesquioxane and polymethyl methacrylate cross-linked polymer, and a coordination auxiliary agent composed of silica silylate and octyl polymethylsiloxane, and utilizes the synergistic cooperation between the three to significantly improve the mixing uniformity of the various components in the powder-to-cream process when applying lip cosmetics, thereby achieving a better cream-forming effect.

[0046] Comparative Example 7 A form-changing lip cosmetic, which differs from Example 1 in that the coordination auxiliary agent is octyl polymethylsiloxane.

[0047] Performance Testing Test Samples: The morphological transformation lip cosmetics obtained in Examples 1-17 were selected as test samples 1-17, and the morphological transformation lip cosmetics obtained in Comparative Examples 1-7 were selected as control samples 1-7.

[0048] Test method: Conduct a viscosity jump test on the form-changing lip cosmetics. The greater the viscosity increase, the more evenly dispersed and tightly integrated the raw materials are after frosting, and the better the overall frosting effect.

[0049] First, the initial viscosity of the morphologically transformed lip cosmetics was measured using a rotational viscometer, denoted as A. Then, five women aged 25-35 years with at least three years of cosmetics experience were randomly selected. Using a small N33 lip brush with 9mm wide and 10mm long bristles, the lip makeup was applied to the lips. After the powder-to-cream conversion was complete, a small amount of the cream was taken and the viscosity was measured using the same method. The average value of the five samples was taken and recorded as B. Finally, the viscosity increase ratio is calculated, which is (BA) / A. The larger the viscosity increase ratio, the better the frosting effect when applying the morphologically transformed lip cosmetics.

[0050] After the above tests were performed on the test samples 1-17 and the control samples 1-7, the test results were recorded in Table 9.

[0051] Table 9 Test results of test samples 1-17 and control samples 1-7 Combining Examples 1-3 and Comparative Examples 1-7 with Table 9, it can be seen that the present application uses functional powder A composed of mica, perlite and silica, functional powder B composed of polymethylsilsesquioxane and polymethyl methacrylate cross-linked polymer, and coordination auxiliary agent composed of silica silylate and octyl polymethylsiloxane, and supplemented with other raw materials. The obtained form-transforming lip cosmetics can show a better frosting effect when applied; at the same time, if only any one of mica, perlite and silica is used as functional powder A, or polymethylsilsesquioxane is used as functional powder B, the lip cosmetics can be applied to the lip lining. When any one of functional powder A, functional powder B and polymethyl methacrylate crosspolymer is used alone as functional powder B, or any one of silica silylate and octyl polymethicone is used alone as a coordinating auxiliary agent, it is found that the viscosity increase ratio of the morphological transformation lip cosmetics obtained by the above test is significantly reduced, indicating that its cream-forming effect is lost. This shows that only when the functional powder A, functional powder B and coordinating auxiliary agent of a specific composition are used in combination can the mixing uniformity of the various components in the powder-to-cream process of lip cosmetics be significantly improved, thereby achieving a better cream-forming effect.

[0052] From Example 1 and Examples 4-9, and Table 9, it can be seen that the selection of the weight proportions of mica, perlite, and silica in functional powder A, the selection of the weight proportions of polymethylsilsesquioxane and polymethyl methacrylate crosspolymer in functional powder B, and the selection of the weight proportions of silica silylate and octyl polymethicone in the coordination auxiliary agent all result in form-transforming lip cosmetics with excellent and stable application quality.

[0053] From Example 1 and Examples 10-17 and Table 9, it can be seen that the selection of colorants, emulsifiers, moisturizers, skin conditioners, and film-forming agents can all meet the application requirements of the form-shifting lip cosmetics, so that the form-shifting lip cosmetics have a stable and better frosting effect during application.

[0054] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
