Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to a high-pressure micro-jet long-lasting makeup composition and a preparation method and application thereof. Background Art

[0002] With the upgrading and changes in public consumption and aesthetic concepts, more and more consumers have begun to pay attention to their external image. As the key to the entire makeup look, foundation has long been highly concerned by makeup professionals.

[0003] However, among the existing products, no matter which type of foundation, there are problems of not being long-lasting and not controlling oil to varying degrees. The main reason is that the amount of oil produced by the skin increases during daily work, and the ingredients such as oil, filling powder, and film-forming agent in the foundation come into contact with the sebum secreted by the skin and are soaked into the entire makeup, resulting in the foundation not being able to control oil and not being long-lasting.

[0004] The above issues have always been the focus of long-term attention in the foundation category of the cosmetics industry. Existing technologies include adding functional oil-control powder ingredients, changing the oil-water ratio, adding film-forming agents, etc. to enhance the oil-control and makeup-lasting performance of the product. However, the above technical solutions still have shortcomings such as high cost, affecting the production process, and reducing product stability, and cannot achieve the ideal performance level.

[0005] In summary, the current development of oil-control cosmetic compositions faces many problems. How to provide a cosmetic product that has both long-lasting and efficient oil control and long-lasting makeup functions has important social and economic significance and practical value.

[0006] Therefore, it is urgent to develop a new technical solution to solve the problems existing in the prior art. Summary of the invention

[0007] Based on this, the present invention provides a high-pressure micro-jet long-lasting makeup composition and its preparation method and application. The present invention adopts a specific functional powder and an oil-control powder compound, and after high-pressure micro-jet treatment, it is mixed with film-forming agents and other ingredients. The various components have excellent compatibility. The product not only has better stability, but also can reduce the contact between the base makeup product and the air, improve the durability of the base makeup, reduce the speed of makeup removal, and quickly absorb oil and continuously reduce the amount of oil produced by the skin, effectively extending the effective time of the product, and the oil control and makeup-lasting effects are significantly improved, solving the problems existing in the prior art, and has good application prospects.

[0008] One object of the present invention is to provide a high-pressure microjet long-lasting makeup composition, wherein the high-pressure microjet long-lasting makeup composition comprises the following components in mass fraction:

[0009]

[0010]

[0011] in,

[0012] The functional powder includes modified mica powder,

[0013] The modified mica powder is epoxy polyether or amino silicone oil modified mica powder.

[0014] Furthermore, the preparation method of the modified mica powder comprises the following steps:

[0015] S1, mixing mica powder and polyacid, heating and reacting to obtain intermediate product 1;

[0016] S2, mixing the intermediate product 1, epoxy resin and catalyst, heating to react, then adding ethanolamine and solvent, and heating to react to obtain the intermediate product 2;

[0017] S3, mixing the intermediate product 2 and amino silicone oil, heating and reacting to obtain modified mica powder.

[0018] Furthermore, in step S1, the temperature of the heating reaction is 40-60°C.

[0019] Furthermore, in step S2, the temperature of the heating reaction is 80-90°C, and the temperature of the temperature-raising reaction is 120-140°C.

[0020] Furthermore, in step S3, the temperature of the heating reaction is 120-160°C.

[0021] Furthermore, the mass ratio of the mica powder to the polyacid is 1:(2-4).

[0022] Furthermore, the mass ratio of the intermediate product 1, epoxy resin and ethanolamine is 1:(30-50):(5-10).

[0023] Furthermore, the mass ratio of the intermediate product 2 to the amino silicone oil is 1:(0.1-2).

[0024] Furthermore, the polyacid is selected from dibasic acid, tribasic acid or tetrabasic acid.

[0025] Furthermore, the solvent is propylene glycol methyl ether.

[0026] Furthermore, the functional powder also includes triethoxyoctylsilane, barium sulfate and titanium dioxide.

[0027] Furthermore, the functional powder comprises triethoxyoctylsilane, barium sulfate, titanium dioxide and modified mica powder in a mass ratio of (1-4):(8-12):(37-43):(36-54).

[0028] Furthermore, the oil-controlling skin care ingredient is selected from one or more of PCA zinc, witch hazel extract, yeast / zinc fermentation product, 1,2-pentanediol, ethylhexylglycerin, and zinc p-phenolsulfonate.

[0029] Furthermore, the oil-controlling powder is selected from one or more of polyacrylate, silica, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer, and bismuth oxychloride.

[0030] Specifically, the surface of polymethyl methacrylate has a concave-convex ultrafine spherical powder. After being treated with microjets, the particle size is smaller, reaching the micron level, so it has higher oil absorption, water absorption, and stronger spreadability and absorption; silica has a microsphere structure. After being treated with microjets, the particle size is smaller, reaching the micron level, and the surface area is larger. The spherical silicone resin powder can absorb more facial oil, making the face more refreshed, avoiding making the entire foundation appear heavy, and making the foundation more durable and fit; vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer is composed of a silicone rubber core, chemically bonded to the silicone resin shell, which can provide a smooth touch while absorbing oil.

[0031] Further, the film-forming agent is selected from one or more of trimethylsiloxysilicate, acrylic acid (ester) / polydimethylsiloxane copolymer, polymethyl silsesquioxane, butyl acrylate / hydroxypropyl polydimethylsiloxane acrylate copolymer, isododecane, isobutyl methacrylate / bis-hydroxypropyl polydimethylsiloxane acrylate copolymer, butyl acrylate / hydroxypropyl polydimethylsiloxane acrylate copolymer, isobutyl methacrylate / bis-hydroxypropyl polydimethylsiloxane acrylate copolymer, cyclopentasiloxane, polydimethylsiloxane alcohol, and C24-28 alkyl polymethylsiloxane.

[0032] Specifically, trimethylsiloxysilicate is a co-hydrolysis product of tetraalkoxysilane and trimethylethoxysilane, which can prevent the migration of color powder and form a breathable film on the skin, making the base makeup more solid and prolonging the time of dull base makeup; acrylic acid (ester) / polydimethylsiloxane copolymer is a volatile silicone oil dissolved product with acrylic acid as the main chain and silicone grafted on the side chain. After the volatile components evaporate, a soft film with extremely high dispersibility, lubricity and oxygen permeability can be obtained, and the dispersibility of inorganic powders can also be improved; polymethyl methacrylate / polydimethylsiloxane copolymer Semi-silicones have good compatibility with oils and fats. After forming a film, it is dry and tough and not easy to break. Butyl acrylate / hydroxypropyl polydimethylsiloxane acrylate copolymer uses polybutyl acrylate as the main chain and polysiloxane as the grafting monomer to generate a copolymer with a low glass transition temperature. It is volatile at room temperature and can be dissolved in low-viscosity silicone oil and various oils, such as cyclic silicone oil, dimethyl silicone oil, hydrocarbon oil, mineral oil, ester and fatty oil. It is easier to spread than ordinary organic polymers to form a smooth, non-sticky, non-greasy continuous wet film; Methyl Isobutyl acrylate / bis-hydroxypropyl dimethicone acrylate copolymer is a copolymer solution of 40% isobutyl methacrylate and silicone-grafted acrylate dissolved in fast-evaporating isoparaffin. When the hydrocarbon oil evaporates, it quickly forms a breathable hard film on the skin, which has a smooth surface and strong flexibility. The mixed solution of cyclopentasiloxane, trimethylsiloxysilicate and dimethicone alcohol has a 50% effective content and is plasticized by dimethicone alcohol. It is more supple and also makes the skin more shiny. Plus, compared with trimethylsiloxysilicate, it improves makeup effect, flexibility, water resistance and oil resistance; a mixed solution of cyclopentasiloxane, trimethylsiloxysilicate and C24-28 alkyl polymethylsiloxane, 50% active content, C24-28 alkyl is grafted on the structure of trimethylsiloxysilicate, compared with ordinary trimethylsiloxysilicate, it is more elastic and flexible, and compared with standard trimethylsiloxysilicate, it improves makeup effect, flexibility, water resistance and oil resistance.

[0033] Furthermore, the functional powder and the oil-control powder are treated by high-pressure microfluidization.

[0034] Another object of the present invention is to provide a method for preparing the above-mentioned high-pressure micro-jet long-lasting makeup composition, comprising the following steps:

[0035] Functional powder and oil-control powder are added to a microfluidizer, and after high-pressure microfluidizer treatment, the functional powder and polydimethylsiloxane are mixed, stirred evenly, a film-forming agent is added, stirred at 60-90° C., the oil-control powder is added, stirred evenly, the oil-control skin care ingredients are added after cooling, and the product is obtained by microfluidizer homogenization.

[0036] Another object of the present invention is to provide an application of the high-pressure microjet long-lasting makeup composition in base makeup cosmetics.

[0037] The present invention has the following beneficial effects:

[0038] The present invention provides a high-pressure micro-jet long-lasting makeup composition, which is obtained by compounding functional powders treated by high-pressure micro-jet, oil-control powders, oil-control skin care ingredients, film-forming agents, and polydimethylsiloxane. The functional powders include special modified mica powders, which first react hydroxyl-rich mica powders with polyacids to obtain an intermediate product 1 with active carboxyl groups introduced, and then further react with epoxy resin to introduce epoxy groups, and then polycondense with ethanolamine using propylene glycol methyl ether as a solvent to obtain an intermediate product 2 with epoxy amino polyether coated on the surface, and finally react with amino silicone oil to obtain a modified mica powder with polysiloxane molecular chains and amino groups introduced. The modified mica powder has a more regular surface. At the same time, siloxane and polyether segments are introduced. After being mixed with triethoxyoctylsilane, barium sulfate and titanium dioxide and treated with high-pressure microfluidization, it can form a uniform micron-sized powder, which has strong biological affinity, good light reflection and light scattering effects, and enhances the compatibility of functional powder with oil-control powder, film-forming agent and polydimethylsiloxane, so that the composition has a more uniform and stable dispersion effect. In addition, the large number of active groups such as amino, carboxyl and ether bonds introduced into the modified mica powder increase more active sites, so that it can form adsorption and cross-linking effects with oil-control skin care ingredients and other materials with active groups, further improving the stability of the composition. After compounding with the oil-control powder treated with microfluidization, it can exert the function of absorbing oil for a long time and achieve the effect of regulating the water-oil balance of the skin.

[0039] The present invention also uses multiple film-forming agents such as siloxane and polyacrylic acid (ester) materials to form multiple physical and biochemical film barriers. The film layer has excellent compatibility with functional powders and oil-control powders. The silicone segment provides better film-forming properties and flexibility, and also improves the lubrication and air permeability of the film layer; polyacrylic acid (ester) materials can also form intermolecular forces with active powders, and have the characteristics of being firm, smooth, and non-greasy, so that the film layer has a soft and hard multi-layer structure, thereby protecting the base makeup from pollution from the outside air, and can also reduce the penetration of skin oils into the makeup through the protective film, reduce the speed of makeup removal, and thus extend the durability of the base makeup to the greatest extent.

[0059] Table 1 Components and mass fractions in high-pressure microjet long-lasting makeup composition

[0060]

[0061]

[0062] The preparation method of the high-pressure micro-jet long-lasting makeup composition comprises the following steps:

[0063] According to the above mass fraction, the functional powder and the oil-control powder are added to the microfluidizer and subjected to high-pressure microfluidization treatment (100 Pa).
