Description

Technical Field

[0001] The present application belongs to the technical field of daily necessities, and specifically relates to a highlight powder, a preparation method and an application. Background Art

[0002] Highlighter products are a type of makeup product that can brighten and modify facial contours. They are often used on parts such as the chin, cheekbones, forehead and bridge of the nose. They can enhance the gloss and fullness of the skin. Highlighters of different textures can create different makeup effects.

[0003] The main ingredients of highlighter powder include titanium dioxide, zinc oxide, silica, mica, etc. These ingredients can not only cover the spots and dullness on the skin and quickly fake white, but also increase the gloss and three-dimensionality of the skin through the reflection of light on the face by high-brightness tiny particles.

[0004] However, the highlight powder currently available on the market is prone to flying when being removed, and after being used several times, the surface of the powder block tends to become dry and hard, and develop oily spots, making it difficult to remove the powder later and reducing the makeup durability. Summary of the invention

[0005] The present application provides a highlight powder, a preparation method and an application, aiming to provide a highlight powder that is shiny, easy to apply, has a delicate skin feel, does not fly away, has a good makeup-lasting effect and can improve the problem of drying and hardening after repeated use.

[0006] In a first aspect of the present application, a highlight powder is provided. The average particle size of the highlight powder is 70 μm to 100 μm.

[0012] In a feasible implementation manner of the first aspect of the present application, the highlight powder satisfies at least one of the following conditions:

[0014] a. The powder component includes a filler powder and a coloring powder;

[0015] Optionally, based on the total mass percentage of the highlight powder being 100%, the filling powder includes 0.5% to 2% of vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer, 3% to 5% of HDI / trimethylol hexyl lactone cross-linked polymer, and 10% to 13% of synthetic fluorphlogopite;

[0016] Optionally, the coloring powder includes one or more of titanium dioxide, pearl powder and pearlescent agent; Optionally, the mass percentage of the pearlescent powder is 50% to 60% based on the total mass percentage of the high gloss powder as 100%; Optionally, the average particle size of the pearlescent agent is 70 μm to 100 μm;

[0017] b. The oil component includes one or more of octyl dodecanol, cetyl ethyl acetate and squalane;

[0018] Optionally, based on the total mass percentage of the highlight powder being 100%, the oil component includes 16% to 24% of octyldodecanol, 1% to 3% of cetyl alcohol ethyl acetate and 0.1% to 2% of squalane;

[0019] c. Inorganic salts include one or more of potassium chloride, sodium chloride and sodium sulfate.

[0020] In a feasible implementation manner of the first aspect of the present application, the moisture content of the highlight powder is 0.2% to 0.5%.

[0021] In a feasible implementation manner of the first aspect of the present application, the hardness of the highlight powder is 8gf to 22gf, and can be optionally 11gf to 20gf.

[0022] A second aspect of the present application provides a method for preparing a highlight powder, the preparation method comprising:

[0023] Mixing octyl dodecanol and ethyl cellulose to form a thickener, and placing the thickener, inorganic salt, oil component, emulsifier, and adhesive in water for emulsification and homogenization to form a first mixture;

[0024] The first mixture is mixed with the powder component and the wax component to form a second mixture;

[0025] The second mixture is homogenized with a preservative (eg, chlorphenesin, caprylyl glycol) and post-treated to obtain a high gloss powder.

[0026] In a feasible implementation of the second aspect of the present application, octyldodecanol and ethyl cellulose are mixed to form a thickener, and the thickener is placed in water with an inorganic salt, an oil component, an emulsifier, and a binder for emulsification and homogenization to form a first mixture. The first mixture may also include some wax components.

[0027] In a feasible implementation of the second aspect of the present application, the preparation method satisfies at least one of the following characteristics:

[0029] e. mixing octyldodecanol and ethyl cellulose to form a thickener, and placing the thickener and inorganic salts, oil components, emulsifiers, and adhesives in water for emulsification and homogenization to form a first mixture, wherein the viscosity of the thickener is 2500mPa·s to 3500mPa·s;

[0030] f. homogenizing the second mixture with a preservative (e.g., chlorphenesin, caprylyl glycol), and post-treating the mixture to obtain a high gloss powder, comprising:

[0031] The second mixture is homogenized with chlorphenesin and caprylyl glycol, and dried until the moisture content in the material is 30% to 50% of the total mass of the material to obtain a high-gloss powder block;

[0032] The highlight powder block is placed in a freeze dryer for quick freezing, so that the water in the highlight powder block is turned into solid ice to obtain a frozen highlight powder block;

[0033] In a vacuum environment, the frozen highlight powder block is heated to convert the solid ice in the highlight powder block directly into gaseous water vapor, and the water vapor is recovered to obtain highlight powder.

[0034] The third aspect of the present application provides an application of the highlight powder provided in the first aspect of the present application in cosmetics, and the cosmetics include one or more of eye shadow, blush and liquid foundation.

[0035] The average particle size of the highlight powder of the present application is 70μm to 100μm, the particle size is large, and the highlight powder is shiny. On this basis, the highlight powder of the present application includes a relatively high mass percentage of oil components, and through the mutual matching of thickeners, inorganic salts, emulsifiers and adhesives, the high content of oil is wrapped in the water phase to form a special water-in-oil emulsification system. At the same time, the water-in-oil emulsification system can make the powder component more evenly dispersed in the emulsion, and then the wax component is compounded to connect the oil phase and the powder phase, so that the high content of oil components is wrapped inside by the powder, and the high content of oil components can be slowly released from the powder during use. Therefore, the highlight powder of the present application not only has a large particle size and shiny highlight, but also is soft and sticky to the skin, easy to apply, and has a delicate and soft skin feel. It is not easy to become dry and astringent in the later stage of use, and it is even closer to the skin without flying powder.

[0036] In addition, the inventors found that the type of each component in the highlight powder of the present application and the selection of their mass percentage are also very important. 5% to 10% of emulsifier, 0.1% to 1% of inorganic salt, 2% to 4% of tackifier and 0.1% to 0.4% of adhesive can form a special water-in-oil emulsification system with a mass percentage of 18% to 25% of oil component, and then compounding 0.6% to 3% of wax component can better connect the oil phase and the powder phase, thereby forming the highlight powder of the present application. For example, when the mass percentage of the emulsifier is less than 5%, there is a risk of not being able to completely emulsify the oil, and the dispersibility of the powder component is not good. Too high an emulsifier content will irritate the skin. For example, inorganic salts within the above mass percentage range can increase the viscosity of the system. If the amount added is too little or not added, the drying time needs to be extended, which will increase the formula cost. If too much is added, the material solidifies too quickly, and the final exquisite grinding effect of the semi-finished product cannot be presented. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the invention purpose, technical scheme and beneficial technical effect of the present application clearer, the present application is further described in detail in conjunction with the embodiments below. It should be understood that the embodiments described in this specification are only for explaining the present application, not for limiting the present application.

[0039] For simplicity, only some numerical ranges are explicitly disclosed herein. However, any lower limit can be combined with any upper limit to form an unambiguous range; and any lower limit can be combined with other lower limits to form an unambiguous range, and any upper limit can be combined with any other upper limit to form an unambiguous range. In addition, although not explicitly stated, each point or single value between the range endpoints is included in the range. Thus, each point or single value can be combined with any other point or single value as its own lower limit or upper limit or with other lower limits or upper limits to form an unambiguous range.

[0040] In the description herein, when a composition is described as containing, comprising or including specific components, or when a process is described as containing, comprising or including specific process steps, it is expected that the composition of the present application also consists essentially of or consists of the components, and the process of the present application also consists essentially of or consists of the process steps.

[0041] The use of the terms "including," "comprising," "containing," and "having" should generally be interpreted as open ended and non-limiting unless expressly stated otherwise.

[0042] In the description of this article, it should be noted that, unless otherwise specified, “above” and “below” are inclusive of the number itself, and the “multiple” in “one or more” means more than two.

[0043] The above-mentioned summary of the invention of the present application is not intended to describe each disclosed embodiment or each implementation in the present application. The following description more specifically illustrates exemplary embodiments. In many places throughout the application, guidance is provided by a series of examples, which can be used in various combinations. In each example, enumeration is only used as a representative group and should not be interpreted as exhaustive.

[0044] The inventors found that highlight products have poor three-dimensional and delicate effects. Although highlight powder is shiny, it feels rough on the skin, especially highlight products prepared by traditional pressed powder and liquid powder. In addition, powder is easy to fly when taking out, and it is not moist enough; the shape is single, lacks layering, and is not three-dimensional enough; at the same time, after several uses, the surface of the powder block is easy to dry and harden, and oil spots appear, making it more difficult to take out the powder later.

[0045] In view of this, the present application provides a highlight powder, a preparation method and an application, aiming to provide a highlight powder that is shiny, easy to apply, has a delicate skin feel, does not fly away, has a high makeup lasting effect and can improve the problem of drying and hardening after repeated use.

[0046] In the embodiment of the first aspect of the present application, a highlight powder is provided. The average particle size of the highlight powder is 70 μm to 100 μm. Taking the total mass percentage of the highlight powder as 100% as a reference, the highlight powder includes the following components in mass percentage:

[0047] Powder component, 50% to 70%; oil component, 18% to 25%, optionally 20% to 24%; thickener, 2% to 4%; emulsifier, 5% to 10%; wax component, 0.6% to 3%; adhesive, 0.1% to 0.4%; inorganic salt, 0.1% to 1%.

[0048] The average particle size of the highlight powder of the present application is 70μm to 100μm, the particle size is large, and the highlight powder is shiny. On this basis, the highlight powder of the present application includes a relatively high mass percentage of oil components, and through the mutual matching of thickeners, inorganic salts, emulsifiers and adhesives, the high content of oil is wrapped in the water phase to form a special water-in-oil emulsification system. At the same time, the water-in-oil emulsification system can make the powder component more evenly dispersed in the emulsion, and then the wax component is compounded to connect the oil phase and the powder phase, so that the high content of oil components is wrapped inside by the powder, and the high content of oil components can be slowly released from the powder during use. Therefore, the highlight powder of the present application not only has a large particle size and shiny highlight, but also is soft and sticky to the skin, easy to apply, and has a delicate and soft skin feel. It is not easy to become dry and astringent in the later stage of use, and it is even closer to the skin without flying powder.

[0049] In addition, the inventors found that the type of each component in the highlight powder of the present application and the selection of their mass percentage are also very important. 5% to 10% of emulsifier, 0.1% to 1% of inorganic salt, 2% to 4% of tackifier and 0.1% to 0.4% of adhesive can form a special water-in-oil emulsification system with a mass percentage of 18% to 25% of oil component, and then compounding 0.6% to 3% of wax component can better connect the oil phase and the powder phase, thereby forming the highlight powder of the present application. For example, when the mass percentage of the emulsifier is less than 5%, there is a risk of not being able to completely emulsify the oil, and the dispersibility of the powder component is not good. Too high an emulsifier content will irritate the skin. For example, inorganic salts within the above mass percentage range can increase the viscosity of the system. If the amount added is too little or not added, the drying time needs to be extended, which will increase the formula cost. If too much is added, the material solidifies too quickly, and the final exquisite grinding effect of the semi-finished product cannot be presented.

[0050] In some embodiments, the viscosity enhancer includes ethyl cellulose and octyldodecanol in a mass ratio of 1:(2-8), and optionally 1:(3-6).

[0051] When octyl dodecanol is combined with ethyl cellulose in the above range, the two can form a thickener with a viscosity of 2500mPa·s to 3500mPa·s. The thickener in this range can be combined with emulsifiers, inorganic salts, and adhesives to better wrap the oil components and disperse the powder particles. The highlight powder formed can cover the skin texture to make the light refraction angle closer to the same, thereby increasing the brightness of the highlight powder. If the viscosity is too low, the thickening effect is not good and a more shiny effect cannot be achieved. If the viscosity is too high, it is difficult to disperse in the formula and synergize with other components.

[0052] Octyldodecanol has a transdermal promoting effect and is often used as a lubricant, emulsifier, solvent and thickener in cosmetics. For drugs with poor transdermal performance, microemulsion with octyldodecanol as an excipient can increase the transdermal speed. Ethyl cellulose is a white to light gray flowable paste and is used as a thickener, film-forming agent and viscosity controller in cosmetics.

[0053] In some embodiments, the viscosity of the tackifier is 2500 mPa·s to 3500 mPa·s.

[0054] In some embodiments, the emulsifier includes polysorbate-60 and polyglycerol 10-laurate in a mass ratio of 1:(0.5-2.0).

[0055] In some embodiments, the wax component includes one of synthetic wax powder, triphenin, or a combination thereof.

[0056] In some embodiments, the wax component includes synthetic wax powder and triphenol in a mass ratio of 1:(2-4); optionally, based on the total mass percentage of the highlight powder as 100%, the wax component includes 0.1%-1% of synthetic wax powder and 0.5%-2% of triphenol.

[0057] Without intending to be limited by any theory or explanation, the above-mentioned combination of emulsifiers and wax components can form a better balance in the entire formula, so that the highlight powder of the present application is not rough on the basis of large-particle pearlescent luster, and feels soft and close to the skin when applied, and is not rough. It also helps to shape the powder block and can be adapted to molds with strong three-dimensionality.

[0058] In some embodiments, the highlight powder satisfies at least one of the following conditions:

[0059] a. The powder component includes a filler powder and a coloring powder;

[0060] Optionally, based on the total mass percentage of the highlight powder being 100%, the filling powder includes 0.5% to 2% of vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer, 3% to 5% of HDI / trimethylol hexyl lactone cross-linked polymer, and 10% to 13% of synthetic fluorphlogopite;

[0061] Optionally, the coloring powder includes one or more of titanium dioxide, pearl powder and pearlescent agent; Optionally, the mass percentage of the pearlescent powder is 50% to 60% based on the total mass percentage of the high gloss powder as 100%; Optionally, the average particle size of the pearlescent agent is 70 μm to 100 μm;

[0062] b. The oil component includes one or more of octyl dodecanol, cetyl ethyl acetate and squalane;

[0063] Optionally, based on the total mass percentage of the highlight powder being 100%, the oil component includes 16% to 24% of octyldodecanol, 1% to 3% of cetyl alcohol ethyl acetate and 0.1% to 2% of squalane;

[0064] c. Inorganic salts include one or more of potassium chloride, sodium chloride and sodium sulfate.

[0065] A 5% potassium chloride solution is added as a suspending agent, and the viscosity of the system is increased by adding inorganic salts. This process is to increase the number of associations of micelles formed by surfactants in aqueous solution through the presence of electrolytes, resulting in the transformation of spherical micelles into rod-shaped micelles, thereby increasing the movement resistance, increasing the viscosity of the system, thickening the material, and solidifying it quickly, which has a lifting effect on the grid disk and prevents it from sinking to the bottom. The advantage of adding potassium chloride solution is that it can speed up the solidification of the material and reduce the time required for high-gloss drying and molding. If the amount added is too little, the drying time needs to be extended, which will increase the formula cost. If too much is added, the material solidifies too quickly and the final exquisite grinding effect of the semi-finished product cannot be presented. If a certain amount of binder is added, the material can also reach the corresponding thickness, but the semi-finished powder block is not easy to remove the powder, and the makeup effect is not good.

[0066] In some embodiments, the binder includes gellan gum.

[0067] The combination of gellan gum and ethyl cellulose in the thickener is more solid, and due to the existence of the emulsification system, the pearlescent can be better dispersed in the emulsion, improving the dispersibility of the pearlescent and reducing the possibility of clumping and powder floating after the highlighter is applied on the face.

[0068] In some embodiments, the moisture content of the highlight powder is 0.2% to 0.5%. The moisture content of the highlight powder of the present application is not high, but it is also soft and sticky to the skin and easy to apply.

[0069] In some embodiments, the hardness of the highlight powder is 8 gf to 22 gf, and optionally 11 gf to 20 gf.

[0070] Without intending to be bound by any theory or explanation, the highlight powder of the present application not only has a large particle size, but is also soft and sticky, close to the skin, does not fall off, and has a high degree of moisture.

[0071] A second aspect of the present application provides a method for preparing a highlight powder, the preparation method comprising:

[0072] Mixing octyl dodecanol and ethyl cellulose to form a thickener, and placing the thickener, inorganic salt, oil component, emulsifier, and adhesive in water for emulsification and homogenization to form a first mixture;

[0073] The first mixture is mixed with the powder component and the wax component to form a second mixture;

[0074] The second mixture is homogenized with a preservative (eg, chlorphenesin, caprylyl glycol) and post-treated to obtain a high gloss powder.

[0075] In the preparation process of the highlight powder of the present application, octyldodecanol and ethyl cellulose are first mixed to form a mixed material body with a viscosity within the range of 2500mPa·s to 3500mPa·s, and the mixed material body has the effect of a thickener. Then, the mixed material body is mixed with other components in batches, and the oil component can be better wrapped with an emulsifier, an inorganic salt, an adhesive and a wax component to disperse the powder particles, so that the formed highlight powder can cover the skin texture to make the light refraction angle closer to the same, the highlight is shiny, and it is soft and sticky to the skin, easy to apply, and has a delicate and soft skin feel. It is difficult to become dry and astringent in the later stage of use, and it is even closer to the skin without flying powder.

[0076] In some embodiments, octyldodecanol and ethyl cellulose are mixed to form a thickener, and the thickener is placed in water with an inorganic salt, an oil component, an emulsifier, and a binder for emulsification and homogenization to form a first mixture. The first mixture may also include some wax components.

[0077] In some embodiments, the preparation method satisfies at least one of the following characteristics:

[0078] e. mixing octyldodecanol and ethyl cellulose to form a thickener, and placing the thickener and inorganic salts, oil components, emulsifiers, and adhesives in water for emulsification and homogenization to form a first mixture, wherein the viscosity of the thickener is 2500mPa·s to 3500mPa·s;

[0079] f. homogenizing the second mixture with chlorphenesin and caprylyl glycol, and post-treating the mixture to obtain a high gloss powder, comprising:

[0080] The second mixture is homogenized with a preservative (such as chlorphenesin and caprylyl glycol), and dried until the moisture content in the material is 30% to 50% of the total mass of the material, so as to obtain a high-gloss powder block;

[0081] The highlight powder block is placed in a freeze dryer for quick freezing, so that the water in the highlight powder block is turned into solid ice to obtain a frozen highlight powder block;

[0082] In a vacuum environment, the frozen highlight powder block is heated to convert the solid ice in the highlight powder block directly into gaseous water vapor, and the water vapor is recovered to obtain highlight powder. While removing water, the integrity of the appearance is ensured.

[0083] The present application transforms liquid highlights into solid highlights. The method is different from the previous powder pressing technology. The low-temperature dehydration (freeze-drying) and silicone demolding process of the present invention can make the highlight shape more three-dimensional and exquisite.

[0084] In addition, the present application may also include removing the aluminum plate design, where the hardness support is changed from an aluminum plate to an injection-molded mesh. The mesh can be better hidden inside the highlight and not be exposed at all. The highlight may even have the opportunity to pass the drop test completely without relying on external support and relying on its own highlight powder.

[0085] The third aspect of the present application provides an application of the highlight powder provided in the first aspect of the present application in cosmetics, and the cosmetics include one or more of eye shadow, blush and liquid foundation.

[0086] Example

[0087] The following examples more specifically describe the disclosure of the present application, which are intended for illustrative purposes only, as it will be apparent to those skilled in the art that various modifications and variations are possible within the scope of the disclosure of the present application. Unless otherwise stated, all parts, percentages, and ratios reported in the following examples are by weight, and all reagents used in the examples are commercially available or synthesized according to conventional methods and can be used directly without further processing, and the instruments used in the examples are commercially available.

[0088] Example 1

[0089] The preparation method of the highlight powder in this embodiment comprises:

[0090] The raw materials provided include: Phase A: water, gellan gum, potassium chloride solution, polyglyceryl 10-laurate, polysorbate-60, octyldodecanol, tribehenin, cetyl ethylhexanoate, squalane, VE; Phase B: synthetic fluorphlogopite, synthetic wax, HDI / trimethylol hexyllactone crosspolymer, vinyl polydimethylsiloxane, pearlescent agent; Phase C: chlorphenesin, caprylyl glycol.

[0091] First, premix a mixture of ethyl cellulose and octyl dodecanol in a mass ratio of 1:4 to form a thickener with a certain viscosity. The temperature of this operation process is controlled at 70°C, and then emulsify and homogenize with the compounded phase A. Beat phase B in a powder pot twice, and finally add phase C and homogenize together. Defoam the material and finish the hot filling. Bake until the moisture content in the material is 40% of the total mass of the material. Then enter the freeze dryer and use the freeze-drying technology to quickly freeze the highlight powder block to turn the moisture into solid ice. In a vacuum environment, the frozen highlight is heated in a supercritical state, and the remaining small amount of water is converted from solid to gaseous and evaporated without changing to liquid. The generated water vapor is condensed and recovered by the condenser in the vacuum system to obtain highlight powder.

[0130] Test Section

[0131] Determination method of bulk hardness

[0132] First, samples of each embodiment and comparative example were prepared, and the samples for measurement were obtained by filling a 30 mL screw-top cup with a heated and molten cosmetic material and leaving it overnight at 25° C. For the samples for measurement, the hardness was measured at 25° C. using a FUDOH rheometer RT-2002D·D (manufactured by Leotech Co., Ltd.) with a cylindrical pressure-sensitive shaft at a penetration speed of 6 cm / min and a penetration depth of 10 mm.

[0133] Viscosity measurement method

[0134] The viscosity of the mixed material (thickener) of octyl dodecanol and ethyl cellulose involved in each embodiment and comparative example was tested using an Ubbelohde viscometer at 25° C. The above test results are shown in Table 1.

[0135] Skin feel test

[0136] A public opinion survey method was adopted, and 30 female volunteers aged 20-40 were selected to try out various embodiments and comparative examples, and their skin moisturizing, skin adhesion, brightening effect, degree of powder flying and residue falling, and makeup lasting effect were evaluated, where 5 points were very excellent, 4 points were excellent, 3 points were average, 2 points were poor, and 1 point was very poor; the scoring results were averaged, and the scoring results are shown in Table 2.

[0140]

[0141] As can be seen from Tables 1 and 2, the highlight powder of the embodiment of the present application includes a reasonable combination of the content and types of oil components with a relatively high mass percentage, thickeners, inorganic salts and emulsifiers, adhesives, wax components, and powder components, so that the high-content oil component is evenly wrapped by the powder inside the evenly dispersed powder component, and the high-content oil component can be slowly released from the powder during use. Therefore, the highlight powder of the present application not only has a large particle size and high gloss, but also has good moisture, skin-fitting properties, and brightening effects, and has a high makeup lastingness, a good effect in the later stage of use, and a low production cost.

[0142] Compared with Example 1, Comparative Example 4 has a different preparation method. In Comparative Example 4, octyl dodecanol is treated as one of the oil components in the same way as other oil components, and ethyl cellulose and gellan gum are treated as adhesives in the same way. All substances are directly mixed and compounded into phase A, and then the highlight powder is prepared. Although the formula is the same, the preparation method is different, and the effect of the resulting highlight powder is not as good as that of Example 1. Due to the low emulsifier content in Comparative Example 5, the product was not formed, so the hardness was not tested, and there was no subsequent skin feel test data. Due to the lack of inorganic salts in Comparative Example 6, the molding time of the highlight powder will be prolonged during the preparation process, the baking time will increase, and the production cost will increase.

[0143] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
