Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, and in particular relates to an emulsion-based liquid blush and its preparation process. Background Technology

[0002] Liquid blush is a blush product with a primarily liquid texture. Compared to traditional powder or cream blush, it has a lighter, more hydrating texture that blends naturally with the skin, creating a rosy glow from within. It's suitable for those seeking a natural makeup look or those with dry skin. Characteristics of liquid blush: Lightweight and hydrating texture: Good spreadability, easy to blend, high adherence, and less prone to creasing or clumping, making it suitable for dry seasons or dry skin.

[0003] Liquid blushes come in pure water-based systems, pure oil-based systems, and emulsion systems. Emulsion systems include water-in-oil types. While water-in-oil blushes offer a natural finish, long-lasting wear, are waterproof, and easy to use, they tend to have a higher content of organic powders, resulting in poor formula stability and a tendency to produce oiliness and color banding. Summary of the Invention

[0004] To address the aforementioned technical problems, the objective of this invention is to propose an emulsion-based liquid blush and its preparation process.

[0005] The technical solution of this invention is implemented as follows: A liquid blush emulsion comprising the following raw material components: Water 30%-40%; Moisturizer 6%-15%; Preservatives: 0.7%-2.8%; Magnesium sulfate 0.5%-2%; Polydimethylsiloxane 15%-30%; Setting film-forming agent: 0.5%-3%; Distearate, lithium dimethylammonium montmorillonite, 0.5%-1%; Emulsifier 2.5%-5.5%; Polyglycerol-6 polyricinoleate 0.2%-0.5%; Isonononyl isononanoate 2%-4%; Skin feel improver 6.5%-14%; Colorant 1.5%-6%.

[0006] Preferably, the long-lasting makeup film-forming agent comprises trimethylsiloxysilicate.

[0007] Preferably, the moisturizer includes glycerin and butylene glycol, wherein the glycerin is 1%-5% and the butylene glycol is 5%-10%.

[0008] Preferably, the emulsifier includes PEG-10 polydimethylsiloxane and lauryl PEG-9 polydimethylsiloxane, wherein the PEG-10 polydimethylsiloxane is 2%-4% and the lauryl PEG-9 polydimethylsiloxane is 0.5%-1.5%.

[0009] Preferably, the skin feel improver is a polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer, a polymethyl methacrylate polymer, or a polymethylsilsesquioxane, wherein the polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer is 0.5%-2%, the polymethyl methacrylate polymer is 5%-8%, and the polymethylsilsesquioxane is 1%-4%.

[0010] Preferably, the polydimethylsiloxane is a polydimethylsiloxane with a viscosity of 1.5.

[0011] Preferably, the preservative is 1,2-hexanediol or phenoxyethanol, wherein the amount of 1,2-hexanediol is 0.2%-2% and the amount of phenoxyethanol is 0.5%-0.8%.

[0012] Preferably, the colorant is titanium dioxide or iron oxide pigment, wherein the titanium dioxide is 1%-3% and the iron oxide pigment is 0.5%-3%.

[0013] A process for preparing an emulsion-based liquid blush includes the following steps: Step 1: First, add 1.5 viscosity polydimethylsiloxane and trimethylsiloxysilicate to an emulsifying pot and mix evenly until there are no particles. Then add PEG-10 polydimethylsiloxane, lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane, polyglycerol-6 polyricinoleate, isononyl isononanoate, and polydimethylsiloxane / vinyl polydimethylsiloxane crosslinking polymer. After stirring quickly and evenly, add the powdered raw material distearate dimethylammonium lithium montmorillonite. After homogenizing quickly for 5 minutes and dispersing evenly, add polymethyl methacrylate polymer, polymethyl silsesquioxane, titanium dioxide, and iron oxide color powder. After stirring evenly, start heating to 75-80℃ to obtain the oil phase. Step 2: Add the raw materials: water, glycerin, butanediol, 1,2-hexanediol, magnesium sulfate, and phenoxyethanol to an aqueous phase pot, stir and heat to 80-85℃ to obtain the aqueous phase, and set aside. Step 3: Adjust the temperature of the emulsifying pot to 75-80℃, homogenize at a low speed of 1500 rpm, slowly pour the aqueous phase into the emulsifying pot, then homogenize quickly at 3000 rpm for 5 minutes, then defoam and cool down to below 45℃, and discharge the material to complete the liquid blush emulsion of the present invention.

[0014] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: This invention creates an emulsion-based liquid blush through a specific formulation. The formula utilizes an oil-in-water emulsion, ensuring uniform dispersion of the oil phase and preventing localized water phase aggregation. This reduces the likelihood of droplet coalescence and sedimentation. The slow addition of the water phase during emulsification controls the dispersion morphology, gradually dispersing it into tiny, uniform droplets. This ensures the emulsifier is fully adsorbed at the oil-water interface, forming a stable protective film. Furthermore, the added electrolyte magnesium sulfate promotes intermolecular interactions through bridging, forming a network structure, increasing emulsion viscosity, and preventing sedimentation or oil separation. It also stabilizes the formula. In a W / O emulsion, it slows the coalescence of small water droplets into larger droplets through water molecule diffusion, reducing the chemical potential of the aqueous phase, minimizing water molecule migration across phases, and delaying the ripening process. This slows droplet coalescence and extends the emulsion's stabilization period, improving the stability of the liquid blush. It is less prone to oiliness, eliminates color banding, provides long-lasting wear, is waterproof and sweatproof, has vibrant color, applies evenly, and produces a natural finish.

[0028] The preparation process of the emulsion-based liquid blush in Example 1 includes the following steps: Step 1: First, add 15% of polydimethylsiloxane (1.5 viscosity) and 2% of trimethylsiloxysilicate to an emulsifying pot and mix evenly until there are no particles.

Stir and heat to 80-85°C. During the heating process, if water evaporates, add an additional 1% water to make up the difference. The aqueous phase is then ready for use. Step 3: Adjust the temperature of the emulsifying pot to 75-80℃, homogenize at a low speed of 1500 rpm, slowly pour the aqueous phase into the emulsifying pot, then homogenize quickly at 3000 rpm for 5 minutes, then defoam and cool down to below 45℃, and discharge the material to complete the liquid blush emulsion of the present invention.

[0029] Through Example 1, the resulting material was relatively stable, applied evenly, and had good waterproof performance, basically achieving the expected results. However, the material was too thin, prone to flow, and dried relatively slowly, with some oil seepage. Therefore, Example 2 was implemented. Example

[0030] Water 33.92%; Glycerin 2.0%; Butanediol 6.0%; 1,2-Hexanediol 0.5%; Magnesium sulfate 1.0%; Phenoxyethanol 0.8%; Polydimethylsiloxane 27.5%; Trimethylsiloxane silicate 2.0%; Polyglycerol-6 polyricinoleate 0.5%; PEG-10 polydimethylsiloxane 3.0%; Lauryl PEG-9 polydimethylsiloxane ethyl polydimethylsiloxane 0.8%; Isonononyl isononanoate 2.5%; Polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer 5.0%; Distearate dimethylammonium lithium montmorillonite 0.8%; Polymethyl methacrylate polymer 8.0%; Polymethylsilsesquioxane 2.0%; Titanium dioxide 2.0%; Iron oxide pigment: 1.68%.

[0031] The preparation process of the emulsion-based liquid blush in Example 2 includes the following steps: Step 1: First, add 27.5% polydimethylsiloxane (1.5 viscosity) and 2% trimethylsiloxysilicate to an emulsifying pot and mix evenly until there are no particles. Then add 3% PEG-10 polydimethylsiloxane, 0.8% lauryl PEG-9 polydimethylsiloxane ethyl polydimethylsiloxane, 0.5% polyglycerol-6 polyricinoleate, 2.5% isononyl isononanoate, and 5% polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer.

After homogenizing quickly for 5 minutes and dispersing evenly, add 8% polymethyl methacrylate polymer, 2% polymethyl silsesquioxane, 2% titanium dioxide, and 1.68% iron oxide color powder. After stirring evenly, start heating to 75-80℃ to obtain the oil phase. Step 2: Add the following raw materials to the aqueous phase pot: 33.92% water, 2% glycerol, 6% butanediol, 0.5% 1,2-hexanediol, 1.0% magnesium sulfate, and 0.8% phenoxyethanol. Stir and heat to 80-85°C. During the heating process, if water evaporates, add an additional 1% water to obtain the aqueous phase for later use. Step 3: Adjust the temperature of the emulsifying pot to 75-80℃, homogenize at a low speed of 1500 rpm, slowly pour the aqueous phase into the emulsifying pot, then homogenize quickly at 3000 rpm for 5 minutes, then defoam and cool down to below 45℃, and discharge the material to complete the liquid blush emulsion of the present invention.

[0032] The material obtained in Example 2 was relatively stable and evenly coated. Since only the water in the aqueous phase was reduced, the internal phase was reduced significantly. Although the amount of thickener distearate dimethylammonium lithium montmorillonite and elastomer polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer were increased, the material was still relatively thin and the stability was average. There was no stratification phenomenon. Therefore, Example 3 was implemented. Example

[0033] Water 45.42%; Glycerin 2.0%; Butanediol 6.0%; 1,2-Hexanediol 0.5%; Magnesium sulfate 1.0%; Phenoxyethanol 0.8%; Polydimethylsiloxane 18.0%; Trimethylsiloxane silicate 2.0%; Polyglycerol-6 polyricinoleate 0.5%; PEG-10 polydimethylsiloxane 3.0%; Lauryl PEG-9 polydimethylsiloxane ethyl polydimethylsiloxane 0.8%; Isonononyl isononanoate 2.5%; Polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer 3.0%; Distearate dimethylammonium lithium montmorillonite 0.8%; Polymethyl methacrylate polymer 8.0%; Polymethylsilsesquioxane 2.0%; Titanium dioxide 2.0%; Iron oxide pigment: 1.68%.

[0034] The preparation process of the emulsion-based liquid blush in Example 3 includes the following steps: Step 1: First, add 18% polydimethylsiloxane (1.5 viscosity) and 2% trimethylsiloxysilicate to an emulsifying pot and mix evenly until there are no particles. Then add 3% PEG-10 polydimethylsiloxane, 0.8% lauryl PEG-9 polydimethylsiloxane ethyl polydimethylsiloxane, 0.5% polyglycerol-6 polyricinoleate, 2.5% isononyl isononanoate, and 3% polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer. After stirring quickly and evenly, add 0.8% distearate dimethylammonium lithium montmorillonite powder. After homogenizing quickly for 5 minutes and dispersing evenly, add 8% polymethyl methacrylate polymer, 2% polymethyl silsesquioxane, 2% titanium dioxide, and 1.68% iron oxide color powder. After stirring evenly, start heating to 75-80℃ to obtain the oil phase. Step 2: Add the following raw materials to the aqueous phase pot: 45.42% water, 2% glycerol, 6% butanediol, 0.5% 1,2-hexanediol, 1.0% magnesium sulfate, and 0.8% phenoxyethanol. Stir and heat to 80-85°C. During the heating process, if water evaporates, add 1% water to make up the difference. The aqueous phase is then ready for use. Step 3: Adjust the temperature of the emulsifying pot to 75-80℃, homogenize at a low speed of 1500 rpm, slowly pour the aqueous phase into the emulsifying pot, then homogenize quickly at 3000 rpm for 5 minutes, then defoam and cool down to below 45℃, and discharge the material to complete the liquid blush emulsion of the present invention.

[0035] Example 3 is based on Example 2, but with an increased proportion of internal phase water and a decreased proportion of external phase polydimethylsiloxane and polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer, resulting in a moderate viscosity of the material.

[0036]

[0037] By examining the three embodiments under various conditions, Embodiment 3 showed no oiling, layering, fading, powdering, clumping, or thinning. The consistency of the material reached the expected effect, it was not easy to flow, had good waterproof performance, and dried at a moderate speed. It had good extensibility, was easy to spread, had high conformability, and was not prone to powdering or clumping.

[0038] Based on the above implementation schemes, the scheme of Example 3 was finally selected.

[0039] This invention addresses the shortcomings of the prior art and offers the following advantages: This invention provides an emulsion-based liquid blush. The formula utilizes an oil-in-water emulsion, ensuring uniform dispersion of the oil phase and preventing localized water phase aggregation. This reduces the possibility of droplet coalescence and sedimentation at the source. The slow addition of the water phase during emulsification controls the dispersion morphology, gradually dispersing it into tiny, uniform droplets. This ensures the emulsifier is fully adsorbed at the oil-water interface, forming a stable protective film. Furthermore, the added electrolyte magnesium sulfate promotes intermolecular interactions through bridging, forming a network structure, increasing emulsion viscosity, and preventing sedimentation or oil separation. Simultaneously, it stabilizes the formula. In a W / O emulsion, it slows the gradual coalescence of small water droplets into larger droplets through water molecule diffusion, reducing the chemical potential of the water phase, minimizing water molecule migration across phases, and delaying the ripening process. This slows the rate of droplet coalescence and extends the emulsion's stabilization period. This improves the stability of the liquid blush, reducing oiliness, eliminating color banding, ensuring long-lasting wear, waterproofing, sweatproofing, vibrant color, even application, and a natural finish.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
