Description

Technical Field

[0001] The present invention relates to the technical field of nail polish composition preparation, in particular to a bio-based perfume nail polish composition and a preparation method thereof. Background Art

[0002] Traditional nail polishes generally use ester solvents (such as ethyl acetate and butyl acetate) as their base, which have a distinct pungent odor and certain health risks, especially when used in confined spaces. Although some low-odor or water-based nail polish products are available on the market, they have varying degrees of deficiencies in color rendering, drying speed, and film-forming properties. At the same time, modern consumers are increasingly demanding healthy, environmentally friendly, and personalized fragrance experiences. Existing technologies can no longer meet market demand. Therefore, there is an urgent need for a new green, safe, and fragrant nail polish composition.

[0003] In the existing technology, nail polish usually uses petroleum-based solvents and synthetic resins, which have problems such as high volatile organic compound (VOC) emissions, serious environmental pollution and potential health risks. To address this problem, we propose a bio-based perfume nail polish composition and its preparation method to address the above problems. Summary of the Invention

[0004] The present invention aims to address the shortcomings of prior art nail polishes, which typically use petroleum-based solvents and synthetic resins, resulting in high volatile organic compound (VOC) emissions, severe environmental pollution, and potential health risks. A bio-based perfume nail polish composition and a preparation method thereof are proposed.

[0005] The present application provides a bio-based perfume nail polish composition and a preparation method thereof using the following technical solutions:

[0006] A bio-based perfume nail polish composition comprises raw materials, which include the following components in parts by weight: 30-60 parts of sugarcane fermentation ethanol, 10-25 parts of acetyl tributyl citrate, 5-15 parts of diethyl lauroyl glutamate, 2-10 parts of zein, 1-8 parts of konjac glucomannan, 2-10 parts of rosin acid methacrylate, 1-5 parts of neroli oil, 1-5 parts of ylang-ylang oil, 1-5 parts of sodium alginate, 1-5 parts of chitosan, 2-10 parts of mineral mica, 1-5 parts of shikonin, 1-5 parts of panthenol, 0.1-2 parts of organic bentonite, 0.1-2 parts of carnauba wax nanoparticles, 0.1-2 parts of a photoinitiator, 0.1-1 parts of rosmarinic acid, 0.1-1 parts of sodium lactate, and 1-5 parts of a bio-based polyurethane dispersion.

[0007] Furthermore, the raw materials include the following components in parts by weight: 35-55 parts of sugarcane fermentation ethanol, 15-20 parts of acetyl tributyl citrate, 8-12 parts of diethyl lauroyl glutamate, 4-8 parts of zein, 2-5 parts of konjac glucomannan, 4-8 parts of rosin acid methacrylate, 2-4 parts of neroli oil, 2-4 parts of ylang-ylang oil, 2-4 parts of sodium alginate, 2-4 parts of chitosan, 4-8 parts of mineral mica, 2-4 parts of shikonin, 2-4 parts of panthenol, 0.5-1 part of organic bentonite, 0.5-1 part of carnauba wax nanoparticles, 0.5-1 part of photoinitiator, 0.4-0.8 part of rosmarinic acid, 0.4-0.8 part of sodium lactate, and 2-4 parts of bio-based polyurethane dispersion.

[0008] Furthermore, the raw materials include the following components in parts by weight: 45 parts of sugarcane fermentation ethanol, 18 parts of acetyl tributyl citrate, 10 parts of diethyl lauroyl glutamate, 6 parts of zein, 3 parts of konjac glucomannan, 6 parts of rosin acid methacrylate, 3 parts of neroli oil, 3 parts of ylang-ylang oil, 3 parts of sodium alginate, 3 parts of chitosan, 6 parts of mineral mica, 3 parts of shikonin, 3 parts of panthenol, 0.8 parts of organic bentonite, 0.8 parts of carnauba wax nanoparticles, 0.8 parts of photoinitiator, 0.6 parts of rosmarinic acid, 0.6 parts of sodium lactate, and 3 parts of bio-based polyurethane dispersion.

[0009] The present invention also provides a method for preparing a bio-based perfume nail polish composition, wherein the bio-based perfume nail polish composition is the above-mentioned bio-based perfume nail polish composition, comprising the following steps:

[0010] S1: prepare raw materials and pre-treat them;

[0011] S2: Mix and dissolve the pretreated raw materials in proportion;

[0012] S3: filtering the mixed raw materials to obtain a clarified mixed liquid;

[0013] S4: cooling and aging the filtered mixed solution;

[0014] S5: vacuum treating the aged mixed liquid;

[0015] S6: Packaging the treated mixed liquid and labeling it to obtain finished nail polish products;

[0016] S7: Conduct sampling inspection on the packaged nail polish products.

[0017] Furthermore, in the S1, the sugarcane fermentation ethanol is filtered through a microporous filter membrane to remove impurities and tiny particles. The pore size of the microporous filter membrane is 0.1-0.5 μm, ensuring its purity and clarity, and providing a pure solvent basis for subsequent mixing. Acetyl tributyl citrate and diethyl lauroyl glutamate are heated and stirred in a 40-50°C water bath for 10-15 minutes to fully dissolve and mix evenly to form a stable oil phase mixture to improve compatibility and dispersibility with other raw materials. Zein is dried at 60-70°C for 2-3 hours to remove moisture, and then crushed into a fine powder of 100-200 mesh to increase its dispersion uniformity in the mixed system, which helps to improve film-forming performance. Konjac grape The mannan is dried at 30-40° C. for 12-24 hours to prevent agglomeration and crushed to 150-200 mesh. The konjac glucomannan is then mixed with rosin acid methacrylate, mineral mica, and shikonin using a high-speed blender at a speed of 800-1000 rpm for 15-20 minutes to fully mix the components and form a uniform powder mixture, thereby providing a good foundation for subsequent dispersion. The carnauba wax nanoparticles and organic bentonite are then ground using a high-speed grinder for 30-40 minutes until the particle fineness reaches 0.1-0.3 μm, thereby improving the dispersibility and stability of the nanoparticles in the mixed solution and enhancing the rheological properties and film-forming strength of the nail polish.

[0018] Furthermore, in S2, the pretreated mixture of sugarcane fermentation ethanol, acetyl tributyl citrate and diethyl lauroyl glutamate is added to the reactor and stirred and mixed by a stirring mechanism. The stirring mechanism speed is 1000-1200 rpm and the stirring time is 5-10 minutes to fully mix the components. During the stirring process, the pretreated zein, konjac glucomannan, rosin acid methacrylate, mineral mica, shikonin and other powder mixtures are slowly added. At the same time, a photoinitiator, rosmarinic acid, sodium lactate and bio-based polyurethane dispersion are added. Stirring is continued at 45-55°C for 30-40 minutes to ensure that the components are fully dissolved and evenly dispersed to form a transparent or translucent uniform mixed liquid.

[0019] Furthermore, in S3, the mixed solution is slowly poured into a filtering device for mechanical filtration at a pressure of 0.1-0.2 MPa to remove undissolved tiny particles and impurities to obtain a clarified mixed solution.

[0020] Furthermore, in S4, the filtered mixed liquid is poured into a cooling container, placed in a cooling environment of 0-5°C, and slowly cooled to 10-15°C. The cooling rate is controlled at 5-8°C / h to prevent crystallization or separation of components in the mixed liquid due to a sudden drop in temperature. The mixed liquid is aged at 10-15°C for 72 hours to fully integrate the aroma components, enhance the harmony and stability of the smell, and optimize the film-forming properties and rheological properties. During the aging process, the mixed liquid is gently stirred for 5-10 minutes every 12 hours to ensure that the components are evenly distributed.

[0021] Furthermore, in S5 and S6, the aged mixed liquid is poured into a vacuum container with a vacuum degree of -0.095 MPa to -0.1 MPa, and maintained for 15-20 minutes to eliminate bubbles generated during the mixing process, ensure that the product texture is fine and uniform, and improve the transparency and gloss of the product. The degassed mixed liquid is passed through a peristaltic pump and divided into pre-cleaned and sterilized light-proof sealed bottles according to the set capacity, and labels are affixed to the sealed bottles to obtain the finished nail polish.

[0022] Furthermore, in S7, a certain number of finished product samples are randomly selected according to the batch number, with a sampling ratio of 1-2‰ per batch, and physical properties tests such as drying time, glossiness, adhesion, hardness, water resistance, and friction resistance are carried out in a standard environment at a temperature of 25°C and a relative humidity of 50%.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This solution uses plant-derived bio-based raw materials such as sugarcane fermentation ethanol, zein, and rosin acid methacrylate as its main ingredients, replacing traditional petroleum-based solvents and synthetic resins. These bio-based raw materials are renewable and biodegradable, reducing environmental pollution and dependence on non-renewable resources, lowering carbon emissions, meeting the requirements of sustainable development, and helping to protect the ecological environment.

[0025] 2. This solution adds natural fragrances such as neroli oil and ylang-ylang oil to give the nail polish a pleasant aroma, which enhances the user experience. It is non-irritating to the skin and respiratory tract, reducing potential harm to human health and is suitable for people with sensitive skin.

[0026] The invention uses sugarcane fermentation ethanol, acetyl tributyl citrate, diethyl lauroyl glutamate, zein, konjac glucomannan, rosin acid methacrylate, neroli oil, ylang-ylang oil, sodium alginate, chitosan, mineral mica, shikonin, panthenol, organic bentonite, carnauba wax nanoparticles, and a photoinitiator, thereby effectively reducing pollution to the environment and dependence on non-renewable resources, and lowering potential harm to human health.

[0031] This embodiment also provides a method for preparing a bio-based perfume nail polish composition. The bio-based perfume nail polish composition is the above-mentioned bio-based perfume nail polish composition, comprising the following steps:

[0032] S1: Filter the sugarcane fermented ethanol through a microporous membrane to remove impurities and tiny particles. The pore size of the microporous membrane is 0.1μm, ensuring its purity and clarity, and providing a pure solvent base for subsequent mixing. Acetyl tributyl citrate and diethyl lauroyl glutamate are heated and stirred in a 40℃ water bath for 10 minutes to fully dissolve and mix evenly to form a stable oil phase mixture to improve compatibility and dispersibility with other raw materials. Zein is dried at 60℃ for 2 hours to remove moisture, and then crushed into a 100-mesh fine powder to increase its dispersion uniformity in the mixed system, which helps to improve film-forming performance. Konjac glucomannan The polysaccharide was dried at 30°C for 12 hours to prevent agglomeration and crushed to 150 mesh. Konjac glucomannan was then mixed with rosin acid methacrylate, mineral mica, and shikonin using a high-speed blender at a speed of 800 rpm for 15 minutes to fully mix the components and form a uniform powder mixture, providing a good foundation for subsequent dispersion. Carnauba wax nanoparticles and organic bentonite were then ground using a high-speed grinder for 30 minutes until the particle size reached 0.1 μm, thereby improving their dispersibility and stability in the mixture and enhancing the rheological properties and film-forming strength of the nail polish.

[0033] S2: adding the pretreated mixture of sugarcane fermentation ethanol, acetyl tributyl citrate and diethyl lauroyl glutamate to a reactor, stirring and mixing by a stirring mechanism at a stirring speed of 1000-1200 rpm for 5-10 minutes to fully mix the components, and slowly adding a powder mixture of pretreated zein, konjac glucomannan, rosin acid methacrylate, mineral mica, shikonin, etc. during the stirring process, and simultaneously adding a photoinitiator, rosmarinic acid, sodium lactate and a bio-based polyurethane dispersion, and continuing stirring at 45-55° C. for 30-40 minutes to ensure that the components are fully dissolved and evenly dispersed to form a transparent or translucent uniform mixed solution;

[0034] S3: Slowly pour the mixed liquid into the filtration equipment for mechanical filtration at a pressure of 0.1-0.2 MPa to remove undissolved tiny particles and impurities to obtain a clear mixed liquid;

Aging at 10-15°C for 72 hours allows the aroma components to fully blend, improve the harmony and stability of the smell, and optimize the film-forming and rheological properties. During the aging process, gently stir the mixed liquid for 5-10 minutes every 12 hours to ensure uniform distribution of the components.

[0036] S5: Pour the aged mixed liquid into a vacuum container with a vacuum degree of -0.095 MPa to -0.1 MPa for 15-20 minutes to eliminate bubbles generated during the mixing process, ensure the product has a fine and uniform texture, and improve the transparency and gloss of the product;

[0037] S6: The degassed mixed solution is pumped into pre-cleaned and sterilized light-proof sealed bottles according to the set volume through a peristaltic pump, and labels are affixed to the sealed bottles to obtain finished nail polish products;
