Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics research and development, and in particular to a durable, waterproof, sweat-proof and smudge-proof dip-type liquid eyeliner pen and a preparation method thereof. Background Art

[0002] Liquid eyeliner is a makeup product. Unlike regular eyeliner, liquid eyeliner has a smooth, velvety texture and a softer tip, allowing for precise application. Dermatologist- and ophthalmologist-tested liquid eyeliner is safer than regular eyeliner and allows for easy definition of your eyes.

[0003] Currently available liquid eyeliners suffer from a lack of staying power, failing to meet user expectations for long-lasting eye makeup. Furthermore, existing liquid eyeliners lack rich color reproduction, resulting in a poor user experience. Therefore, there is an urgent need to design a long-lasting, waterproof, sweat-resistant, and smudge-resistant dip-type liquid eyeliner and its preparation method to address these issues. Summary of the Invention

[0004] The purpose of the present invention is to provide a durable, waterproof, sweat-proof and smudge-proof dip-type liquid eyeliner and a preparation method thereof, so as to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A long-lasting, waterproof, sweat-proof and smudge-proof dip-in eyeliner comprises the following components in percentage by weight: 40%-70% water, 0%-5% xanthan gum, 2%-7% 1,3-propylene glycol, 1%-5% magnesium aluminum silicate, 0%-3% aminomethyl propylene glycol, 1%-6% acrylates / octylacrylamide copolymer, 0%-3% glycerin, 0%-3% bis-PEG / PPG-20 / 5 PEG / PPG-20 / 5 polydimethylsiloxane, 0%-3% methoxy PEG / PPG-25 / 4 polydimethylsiloxane, 0%-3% caprylic / capric triglyceride, 0%-1% pentaerythritol tetrakis-di-tert-butyl hydroxyhydrocinnamate, 10-15% iron oxide toner, 8%-18% styrene / acrylates copolymer, 0%-1% sodium dehydroacetate, 0%-1% phenoxyethanol, and 0%-1% caprylyl glycol.

[0006] Furthermore, the dip-in liquid eyeliner pen has a clear preparation process and includes the following components, which include component A, component B, component C, component D, component E, component F, component G, component H, and component I: The component A comprises water; The component B includes xanthan gum and 1,3-propylene glycol; The component C comprises magnesium aluminum silicate; The component D includes aminomethyl propanediol; The component E includes acrylic acid (ester) / octylacrylamide copolymer, 1,3-propylene glycol and glycerol; The component F includes bis-PEG / PPG-20 / 5 PEG / PPG-20 / 5 polydimethylsiloxane, methoxy PEG / PPG-25 / 4 polydimethylsiloxane, caprylic / capric triglyceride and pentaerythritol tetra(bis-tert-butyl hydroxyhydrocinnamate); The component G includes iron oxide toner; The component H includes styrene / acrylic acid (ester) copolymer and sodium dehydroacetate; The component I includes phenoxyethanol and caprylyl glycol.

[0007] The above-mentioned technical solution utilizes a large number of film-forming agents, namely, acrylates / octylacrylamide copolymer and styrene / acrylates copolymer. Acrylates / octylacrylamide copolymer is a hydrophobic, high-molecular-weight, carboxylated acrylic copolymer that provides water and abrasion resistance while also enhancing the retention of active ingredients on the skin. Styrene / acrylates copolymer creates an exceptionally long-lasting effect, with excellent water resistance, superior adhesion, and abrasion resistance. The combination of these two agents in a scientific ratio creates a super-hydrophobic, long-lasting, and smudge-resistant dip-in eyeliner.

[0008] Furthermore, the weight percentages of 1,3-propylene glycol in the component B and the component E are 2%-7% and 0%-5%, respectively.

[0009] Using the above technical solution, 1,3-propylene glycol can be used as a lubricant and thickener. It can lower the freezing point of the liquid, improve the fluidity of the liquid, and optimize the liquid properties by increasing the viscosity. It can enable the xanthan gum in component B to be better used as a thickener, help maintain the product texture and enhance the skin feel. In component E, when combined with the acrylic acid (ester) / octylacrylamide copolymer, it can enhance the moisturizing and lubricating effects, improve the skin texture and protective effect.

[0010] A method for preparing a dip-in liquid eyeliner pen, for preparing any of the above-mentioned long-lasting waterproof, sweat-proof and smudge-proof dip-in liquid eyeliner pen, characterized by comprising the following steps: Step 1: Use an emulsifying pot for production. Pre-disperse the xanthan gum in component B with 1,3-propylene glycol in the emulsifying pot. Then, add an appropriate amount of water containing component A into the emulsifying pot and heat it. After heating, homogenize and stir it in the emulsifying pot. Then, add component C into the emulsifying pot and heat it to a high temperature for homogenization and stirring. Then, add component D into the emulsifying pot and stir until it is completely dissolved to form mixture A. Step 2: Use a stainless steel drum to prepare the materials, add component E into the stainless steel drum and stir until the mixture B is uniform and paste-like, then add the mixture B into the emulsifying pot and homogenize and stir it with the mixture A; Step 3: Add component F to the emulsifying pot and homogenize and stir evenly, then add component G to the emulsifying pot and homogenize and stir evenly, then use the emulsifying pot to reduce the high temperature and add component H and component I and homogenize and stir evenly until there is no granularity and the material is uniform and fine to form a body; Step 4: After the material in the emulsifying pot has cooled down completely, sieve the material out and then seal the material for storage.

[0011] Furthermore, the emulsifying pot has heating and temperature display functions. In step 1 and step 3, the emulsifying pot needs to maintain a temperature of 45±5° C. for homogenous stirring during the production process.

[0012] Furthermore, in the step 1, the component C is added into the emulsifying pot and then heated to a high temperature of 75±5°C.

[0013] Furthermore, in step 3, the emulsifying pot needs to be cooled to 45±5° C. before adding component H and component I.

[0014] Furthermore, the emulsifying pot has a homogenizing stirring function, the stirring parameter is 1000-2000 rpm / min, and the stirring time for each feeding is 10-20 minutes.

[0015] Furthermore, the stainless steel drum is stirred using an external stirrer with a stirring parameter of 500-1000 rpm / min and a stirring time of 5-10 minutes.

[0016] Furthermore, in step 4, the material body is filtered using a filter net, and the material body is sealed and packaged using a double-layer PE bag.

[0017] In the above technical solution, the present invention provides a long-lasting waterproof, sweat-proof and smudge-proof dip-type liquid eyeliner pen and a preparation method thereof, which has the following beneficial effects: (1) The use of film-forming agents such as acrylic acid (ester) / octylacrylamide copolymer and styrene / acrylic acid (ester) copolymer can increase the retention of active ingredients on the skin, improve the waterproof and anti-abrasion functions, and form a super long-lasting effect.

[0018] (2) The thickening system of xanthan gum and magnesium aluminum silicate makes it feel light on the skin, and with a high content of pigment, it creates a shaping and color-saturated makeup effect. The raw materials are all in compliance with RSPO and VEGAN, and there are no nano materials, so it is an environmentally friendly product that does not involve animal testing.
