Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, specifically to a color makeup powder pen based on freeze-drying or baking powder process and its preparation method. Background Technology

[0002] In the cosmetics industry, chalk-based makeup products are highly favored by consumers due to their portability, ease of use, and direct color application. Their core needs focus on powder texture, lead stability, and ease of use. Currently, most chalk-based makeup pencils on the market are manufactured using traditional pressing and baking processes. The lead is mostly a solid structure, relying on adhesives for bonding. The production process requires balancing the amount of adhesive used with the powder's fluffiness, limiting room for process optimization. Simultaneously, the pencil's fixing method primarily relies on traditional gluing and nesting, necessitating a balance between stability and lead protection to prevent lead loosening during use.

[0003] Existing powder pencils for makeup have significant technical defects: on the one hand, unreasonable lead molding processes result in thick, clumpy powder that easily clumps, leading to issues like powder caking and uneven color application, failing to meet consumers' desire for a "light and smooth" makeup effect; on the other hand, the solid lead structure lacks toughness, and combined with traditional manufacturing processes, it is prone to breakage and crumbling, affecting the user experience; in addition, the pen barrel and lead fixing methods of some products are poorly compatible, which may cause the lead to loosen during writing and carrying, further reducing product reliability.

[0004] As the cosmetics market demands higher standards for product experience and performance, the shortcomings of traditional powder pencils in terms of powder texture, pencil lead stability, and ease of use have become increasingly apparent. Consumers urgently need a new type of powder pencil with a light and even powder texture, a durable pencil lead, and smooth, non-clumping application. Summary of the Invention

[0005] To address the aforementioned technical problems, the first aspect of this invention provides a makeup powder pencil, comprising a pencil lead and a casing; the casing serves to secure the pencil lead to the outside; wherein the raw materials for preparing the pencil lead include a powder component and an emulsion component; the powder component, by mass parts, comprises 18-25 parts of phase A, 0.1-13 parts of phase A1, 20-50 parts of phase B, and 6-15 parts of phase C; the emulsion component, by mass parts, comprises 0.5-1.5 parts of phase D and 80-100 parts of phase E; wherein phase A comprises mica, phase A1 comprises pigment, phase B comprises fillers, molding aids, skin feel modifiers, and stabilizers; phase C comprises oily components and antioxidants; phase D comprises plasticizers; and phase E comprises water, thickening stabilizers, moisturizers, and preservatives.

[0006] This invention utilizes the synergistic ratio of phase B molding aid and phase E polythiating stabilizer, combined with the plasticizing effect of phase D, to create a matrix with both strength and flexibility after mixing the powder components with the emulsion. After being formed through freeze-drying or baking processes, the pencil lead structure is dense and not easily brittle, effectively solving the technical defects of traditional makeup powder pencils, such as poor control of the pencil lead and easy breakage. Makeup powder pencils are not easily broken during use, improving product durability and filling a relevant gap in the domestic industry.

[0007] As one implementation example, the pigments, by weight, include 0-8.0 parts of iron oxide, 0-0.5 parts of Red 40 lake, 0-0.5 parts of Yellow 5 lake, 0-0.5 parts of Yellow 6 lake, 0-0.5 parts of Blue 1 lake, 0-0.5 parts of Red 7 lake, 0-0.5 parts of Red 6 lake, 0-0.5 parts of Red 28 lake, and 0-1.5 parts of carmine.

[0008] In this invention, 0-8.0 parts of iron oxide serve as the core primary colorant, providing basic shades of brown, red, and yellow from light to dark. The high proportion range covers the mainstream color systems of current cosmetics. Various pigments, as high-concentration color adjusters, can accurately correct color deviations through micro-adjustment. Meanwhile, 0-1.5 parts of carmine, as a natural red supplement, can give the color a natural and transparent feel. The multi-component and wide-range proportion design allows for flexible formulation of a rich variety of shades to meet different consumer needs. Meanwhile, lake-based colorants, due to their high color saturation and strong tinting strength, have a single-agent dosage limited to 0-0.5 parts. This avoids problems such as excessive local coloring, clumping leading to uneven color development, and mottled appearance, ensuring that the color powder is evenly dispersed in the powder matrix. Combined with the C-phase oil component, it achieves the effect of light application for color development and multiple layers without feeling heavy. The overall weight of the color powder is 0.1-13 parts, and the raw material system will not cause uneven powder density due to excessive pigment content. This avoids problems such as color difference and cracking of the pencil lead during freeze-drying and baking, while ensuring the structural stability of the pencil lead.

[0009] As an example of an implementable method, the filler includes titanium dioxide, sodium calcium borosilicate, and silica.

[0010] Furthermore, the mass ratio of titanium dioxide, sodium calcium borosilicate, and silica is (16-20):(4-8):(4-8).

[0011] 16-20 parts titanium dioxide serves as the core concealing and brightening powder. This high proportion ensures a high level of makeup application and provides a uniform base for the pigments. 4-8 parts sodium calcium borosilicate enhances the wear resistance and structural strength of the pencil lead, while 4-8 parts silica improves the powder's fluffiness and prevents clumping. The two are mixed in equal proportions, ensuring the pencil lead is not easily broken while avoiding a heavy powder texture. This ratio also balances the density of titanium dioxide with the lightweight properties of silica and sodium calcium borosilicate, resulting in a suitable powder density and flowability. After mixing, the powder is stirred, freeze-dried, and baked to form a uniform matrix, preventing pencil lead cracking and color differences caused by density variations, and ensuring molding stability. At the same time, the three components work synergistically to optimize the skin feel and color application. Titanium dioxide enhances concealing power, silica reduces caking, and sodium calcium borosilicate enhances powder adhesion. The limited proportions ensure the core advantages of a lightweight, even, and easy-to-apply powder while avoiding the negative impact of an excessive amount of any single ingredient on product performance.

[0012] As an implementable example, the molding aid comprises nylon 12 and polymethyl methacrylate, wherein the mass ratio of nylon 12 to polymethyl methacrylate is (3-7):(2.5-4.5).

[0013] The core principle is to balance the structural stability of the pen refill and the characteristics of the powder by complementing the functions and optimizing the ratio of the two molding aids mentioned above. Nylon 12 has high flexibility, and polymethyl methacrylate has excellent adhesion. The ratio of (3-7):(2.5-4.5) can synergistically enhance the adhesion between powder components and the toughness of the pen refill, solving the problem of easy breakage of traditional pen refills. At the same time, this ratio is suitable for freeze-drying and baking processes, ensuring the structural density of the pen refill after molding without affecting the fluffiness of the powder.

[0014] As an implementable example, the skin feel modifier comprises boron nitride, synthetic fluorophlogopite, and polydimethylsiloxane / divinyl polydimethylsiloxane / silsesquioxane crosslinked polymer; the mass ratio of boron nitride, synthetic fluorophlogopite, and polydimethylsiloxane / divinyl polydimethylsiloxane / silsesquioxane crosslinked polymer is (2-4):(2-4):(6-10).

[0015] As an example of an implementable method, the stabilizer includes tin oxide.

[0016] Tin oxide has stable chemical properties and can inhibit the oxidation and deterioration of colorants and oily components in the powder, preventing color fading, darkening or powder clumping during product storage, and ensuring stable performance during the shelf life.

[0017] As an implementable example, the oily component comprises PEG-10 polydimethylsiloxane, behenoxy polydimethylsiloxane, isoamyl cocoate, polydimethyl silicone oil, and triglycerides (behenic acid / isostearate / eicosanoic acid); the mass ratio of PEG-10 polydimethylsiloxane, behenoxy polydimethylsiloxane, isoamyl cocoate, polydimethyl silicone oil, and triglycerides (behenic acid / isostearate / eicosanoic acid) is (1-3):(1-3):(2.5-4.5):(2.5-4.5):(1-3).

[0018] PEG-10 polydimethylsiloxane and behenoxy polydimethylsiloxane, each 1-3 parts, primarily focus on dispersion and skin feel adjustment, reducing powder friction and preventing clumping. Isoamyl cocoate and polydimethylsiloxane, each 2.5-4.5 parts, enhance powder smoothness and skin adhesion, resolving powder caking issues. 1-3 parts triglycerides (behenic acid / isostearate / eicosanoic acid) improve powder adhesion and pencil lead toughness, aiding in breakage prevention. This ratio avoids performance defects caused by excessive amounts of any single ingredient. The low proportion of siloxanes prevents an oily feel, while the medium proportions of esters and silicone oil ensure smoothness without affecting powder fluffiness. The overall ratio allows the oily components to evenly coat powder particles without causing excessive oiliness. The powder agglomerates and the pen refill collapses, achieving a balance between "lightness," "adhesion," and "toughness." In addition, the selected oily components all have good thermal stability, are not easily volatilized or decomposed at high temperatures during the baking process, and have strong compatibility with powder and emulsion components. They can promote the formation of a uniform matrix in the powder-emulsion mixture system. The limited proportion ensures that the amount of oily components is moderate, which not only ensures smooth removal of moisture and dense pen refill formation during freeze-drying, but also avoids oil residue affecting the product's shelf life, while not interfering with the dispersion of pigments and the uniformity of coloring.

[0019] As an example of an implementable approach, the antioxidants include one or more of tocopherol, L-ascorbic acid, isoflavones, nicotinamide, and tea polyphenols.

[0020] Furthermore, the antioxidants mentioned include tocopherol.

[0021] As an example of an implementable method, the plasticizer mentioned includes triethyl citrate.

[0022] Triethyl citrate, as the plasticizer of this invention, has excellent plasticizing and softening effects. It can penetrate into the matrix after the powder component and emulsion are mixed, weakening the rigid bonding between powder particles, improving the flexibility and flexural strength of the pen refill, and precisely solving the core problem of "poor control and easy breakage of the pen refill" in the prior art. At the same time, its softening effect can ensure the structural integrity of the hollow pen refill after molding, avoiding uneven stress and easy cracking caused by the hollow structure. Meanwhile, as an oily plasticizer, triethyl citrate can react with C-phase oily components such as polydimethyl silicone oil and coconut oil isocyanate. Synergistically, pentyl esters and other components form a thin oil film on the surface of powder particles, reducing inter-particle friction and skin contact resistance, thus improving powder smoothness and preventing powder caking. They also enhance the compatibility between pigments and the powder matrix, promoting uniform pigment dispersion. Furthermore, triethyl citrate exhibits excellent thermal stability, resisting volatilization and decomposition under the high temperatures of the baking process, maintaining the stability of the pen refill matrix and preventing embrittlement caused by high temperatures. It also demonstrates strong compatibility with powder and emulsion components, mitigating uneven raw material shrinkage during freeze-drying and preventing pen refill cracking and deformation.

[0023] As an implementable example, the thickening stabilizer comprises magnesium aluminum silicate and sodium polyacrylate, wherein the mass ratio of magnesium aluminum silicate to sodium polyacrylate is (0.5-1.5):(0.2-1.0).

[0024] Magnesium aluminum silicate focuses on improving the thixotropic and suspending properties of the emulsion to prevent raw material sedimentation, while sodium polyacrylate excels at constructing a three-dimensional gel network and enhancing adhesion. The ratio of (0.5-1.5):(0.2-1.0) can synergistically maintain the uniformity of the emulsion without stratification; at the same time, it can enhance the bonding force between the powder components and the emulsion, helping the pen refill to form a dense and stable structure after freeze-drying and baking, avoiding breakage, and without affecting the fluffiness and smoothness of the powder.

[0025] As an implementable example, the moisturizer comprises 1,2-pentanediol, caprylyl glycol, ethylhexylglycerin and glycerin; the mass ratio of 1,2-pentanediol, caprylyl glycol, ethylhexylglycerin and glycerin is (1-3):(0.5-2):(0.4-0.7):(0.1-1).

[0026] This invention optimizes the function and proportion of four types of moisturizers to balance product gentleness, preservative support, and powder compatibility: 1,2-pentanediol and caprylyl glycol are the main moisturizing ingredients, while also enhancing the preservative effect; ethylhexylglycerin has a synergistic effect of moisturizing and antibacterial, broadening the preservative spectrum; glycerin strengthens the skin's surface moisturizing film and alleviates the dryness and irritation of the powder. The overall proportions ensure moisturizing effect, preventing skin tightness during use, while avoiding excessive moisture affecting the freeze-drying and baking of the pen core. The low proportion design does not interfere with the powder's fluffiness and smoothness, and also improves product gentleness.

[0027] As an example of an implementable method, the preservative includes octanoyl hydroxamic acid.

[0028] As an implementable example, the method for preparing the pen refill includes the following steps: S1. Add phase A into the mixer and stir evenly, then add phase B and stir evenly. S2. Add phase A1 and stir well. S3. Add phase C to the injector and inject it into the reaction system of step S2 to obtain the powder component; S4. Add the E-phase raw material to the emulsification pot, stir until the raw material is completely dissolved, and keep warm; S5. Heat phase D, put it into an emulsification pot, and stir it homogenously to obtain the emulsion component. S6. Mix the powder component and the emulsion component, and shape them by freeze-drying or baking powder process to obtain the pen refill.

[0029] The second aspect of the present invention provides a method for preparing a makeup powder pen, comprising: wrapping and fixing the pen core with a shell to obtain a makeup powder pen.

[0030] Beneficial effects (i) This invention utilizes the synergistic bonding of phase B nylon 12 and polymethyl methacrylate, the plasticizing and softening effect of phase D triethyl citrate, and the stable gel network constructed by phase E magnesium aluminum silicate and sodium polyacrylate to give the pen refill both strength and toughness, effectively solving the technical problem of easy breakage of pen refills in traditional products.

[0031] (ii) In this invention, lightweight fillers such as silica and boron nitride in phase B work synergistically with skin feel modifiers to reduce powder density and interparticle friction; multiple oily components in phase C uniformly coat the powder to form a thin oil film, improving fluidity and skin adhesion, achieving the core advantage of lightweight powder, and avoiding problems such as powder caking and skin friction during application.

[0032] (III) The A1 phase color powder combination ensures that the color powder is evenly dispersed in the powder matrix by using a precise ratio of the main color (iron oxide) and the tinting color (various lakes) and the C phase oily dispersion medium; the B phase titanium dioxide provides a uniform concealing base, assists in the pure color development, achieves a uniform and easy coloring effect, and the color powder has excellent stability and is not easy to fade or change color during the product's shelf life.

[0033] (iv) The moisturizing system composed of 1,2-pentanediol, caprylyl glycol and glycerin in phase E relieves the dryness and tightness of the skin caused by the powder; the compound preservative system of ethylhexylglycerin and capryloyl hydroxamic acid achieves long-lasting antibacterial effect with low addition amount, reducing the irritation of high concentration of preservatives; combined with the antioxidant protection of naturally derived mica, cochineal red and tocopherol in phase C, the overall gentleness of the product is improved, making it suitable for makeup use scenarios that come into direct contact with the skin.

[0034] (v) The components in the formula are highly compatible. Phase B stabilizers such as tin oxide and siloxane cross-linked polymers inhibit powder oxidation and agglomeration, while phase E thickening stabilizers ensure that the emulsion system is uniform and does not separate. The freeze-drying and baking processes are compatible with powder-emulsion mixed systems, avoiding shrinkage and cracking during molding, and the pen refill structure is dense. The overall design makes the product less prone to problems such as powder shedding, pen refill cracking, and color deterioration during storage, thus extending the shelf life.
