Description

Technical Field

[0001] The present application relates to the technical field of cosmetics, and more specifically, to a highlight brightening liquid and a preparation method thereof. Background Art

[0002] Clean and bright skin has always been the pursuit of many Asian women, but due to various factors such as personal lifestyle and stress, it is easy to cause dull skin and uneven skin tone. The ordinary foundation liquid on the market is not enough to improve the facial brightening effect. There are many types of cosmetics for brightening facial gloss, improving local dullness on the face, covering nasolabial folds, and filling facial unevenness, such as brightening cream, brightening liquid, brightening contour stick, etc. Among them, brightening liquid is loved by consumers because of its lighter powder and suitable for brightening large areas. In addition to increasing skin gloss and improving local dullness, brightening liquid can also bring its own lighting effect when taking pictures, making the overall makeup effect more natural and three-dimensional.

[0003] In the prior art, a Chinese invention patent with application number CN2021111170468 discloses a cosmetic highlighter and a preparation method thereof. The cosmetic highlighter, calculated as 100% by mass, is composed of the following components in percentage by mass: 18.85-27% of phase A pearlescent agent, 8-16.15% of phase B pearlescent agent, 5-11% of phase C pearlescent agent, 4-9% of phase D pearlescent agent, 4-8.5% of phase E pearlescent agent, 2-6% of phase F pearlescent agent, and the remainder is other additives; the phase A pearlescent agent accounts for 57-79%, 1-6% and 20-37% of the total amount of phase A pearlescent agent, respectively, in percentage by mass. % of aluminum oxide, tin oxide and titanium dioxide; the B phase pearlescent agent is aluminum oxide, tin oxide and titanium dioxide, which account for 46-65%, 1-11% and 34-43% of the total amount of the B phase pearlescent agent respectively by mass; the C phase pearlescent agent is mica, titanium dioxide and iron oxide, which account for 45-69%, 15-28% and 16-27% of the total amount of the C phase pearlescent agent respectively; the D phase pearlescent agent is mica, titanium dioxide and tin oxide, which account for 77-88%, 9-22% and 1-3% of the total amount of the D phase pearlescent agent respectively; the E phase pearlescent agent is mica and titanium dioxide, which account for 51-67% and 33-49% of the total amount of the E phase pearlescent agent respectively.

[0004] With respect to the above-mentioned related technologies, the inventors found that the above-mentioned highlighters for cosmetics use a variety of pearlescent agents in combination and are made through the traditional baking powder process. The powdered pearlescent agents are easily inhaled into the human body through the respiratory tract, which has an adverse effect on the human lungs. In addition, some pearlescent agent particles are large and have sharp edges, which can cause damage to the skin and easily cause skin allergies and other problems. In addition, the highlight powder made by the baking powder process has weak adhesion and is easy to fall off from the face. The makeup is not durable enough and it is difficult to provide a lasting brightening effect. Summary of the invention

[0005] In order to make highlight products less likely to cause allergies and be less likely to be inhaled by the human body while achieving the brightening effect, the present application provides a highlight brightening liquid and a preparation method thereof.

[0006] In the first aspect, the present application provides a highlight brightening liquid, which adopts the following technical solution: A high gloss brightening liquid, comprising the following raw materials in weight percentage: 5-25% of brightening agent, 0.16-10% of coloring agent, 2-30% of thickening agent, 5-15% of film former, 2-4% of emulsifier A, 0.5-2% of emulsifier B, 15-30% of non-volatile oil, 3-7% of volatile oil, 0.2-0.6% of stabilizer, 0.1-0.5% of preservative, 3-8% of moisturizing agent, 0.05-0.1% of essence, and the balance is solvent; the brightening agent is a mixture of bismuth hydroxide, acrolein / acrylic acid copolymer and water; The colorant is selected from at least one of yellow iron oxide paste, red iron oxide paste, black iron oxide paste and lake paste; The emulsifier A is selected from at least one of polyglyceryl-2 dipolyhydroxystearate, lauryl PEG-9 polydimethylsiloxyethyl dimethicone, and cetyl PEG / PPG-10 / 1 dimethicone; The emulsifier B is selected from at least one of polyglyceryl-3 diisostearate, sorbitan isostearate and polyglyceryl-4 isostearate.

[0007] By adopting the above technical scheme, a mixture containing bismuth hydroxide, acrolein / acrylic acid copolymer and water is used as a brightener, which is an oil-in-water type brightener liquid, can replace pearl powder, and is combined with a colorant to produce a special metallic luster. Moreover, the brightener containing bismuth hydroxide is in liquid form, not easily inhaled by the human body, and not prone to allergies, which meets the consumer's demand for mild makeup. At the same time, the liquid product has stronger adhesion to the skin and can provide a lasting brightening effect.

[0008] Bismuth hydroxide can provide hydrogen bond interactions with cells on the surface of the skin. This action will combine with the oxygen of red blood cells, resulting in a proton transfer reaction, making the skin brighter and healthier. In addition, bismuth hydroxide can fill the skin, reduce the visual texture of the skin, make the skin smoother and more delicate, and achieve a certain sun protection effect. Acrolein / acrylic acid copolymer can improve the dispersibility of bismuth hydroxide in the product, making bismuth hydroxide easier to apply evenly on the skin surface.

[0009] Emulsifier A is used as the main emulsifier, and emulsifier B is used as the auxiliary emulsifier. The two work together to emulsify most of the oils and fats, so that the product forms a stable emulsion mixture, avoiding the dust of baked high-gloss products, making the product safer to use. It can also give the product a good texture and touch, improve the spreadability of the product, accelerate the drying and film-forming speed, and make it softer and smoother after application, and easier to apply and absorb.

[0010] Volatile oils can help to better disperse and mix the color powder in the highlight brightening liquid, thereby improving the uniformity and stability of the product, increasing the fit, and improving the spreadability. In addition, volatile oils can bring care effects to the skin, improve the elasticity and radiance of the skin, and provide the skin with certain nourishment and protection while applying makeup. Volatile oils are also water-resistant, which can improve the anti-makeup effect for users in summer or when they are prone to sweating, and enhance the durability of makeup. Non-volatile oils mainly play a role in brightening the skin, improving the moisturizing effect of the product, and increasing the lubricity of the product. Film-forming agents can increase the product's anti-migration ability and provide a lasting makeup effect.

[0011] Optionally, the mass ratio of the colorant to the brightener is 0.8-1:15.

[0012] By adopting the above technical scheme, the colorant and brightener in the above ratio can make the product have a better metallic gloss, so that it is easier to cover skin blemishes, increase the gloss and three-dimensional effect, and create a sense of layering and three-dimensionality, making the makeup more vivid and three-dimensional, and achieving a better makeup effect.

[0013] Optionally, the thickener is selected from at least one of isododecane, a mixture of disteardimonium hectorite and propylene carbonate, silica dimethyl silylate, glyceryl behenate / eicosate, dextrin palmitate and dextrin myristate.

[0015] Optionally, the thickener comprises a mixture of silica dimethyl silylate and isododecane, disteardimethylammonium hectorite and propylene carbonate in a mass ratio of 2:25-30.

[0016] By adopting the above technical scheme, dimethyl silylate silica is an organic silicon compound, and its molecular structure gives it the characteristics of lightness and easy to spread, which can make the product smoother and more ductile, and can also protect the skin and prevent moisture loss, while achieving the effect of oil control, making the makeup more durable and not easy to come off. The mixture of isododecane, disteardimethylammonium hectorite and propylene carbonate can provide a better sense of application, increase the moisturizing and nourishing effects, make the skin smoother, and achieve the effects of moisturizing and oil control. Therefore, the combination with dimethyl silylate silica can increase the long-term water-locking, moisturizing and oil-control effects of the product, thereby prolonging the adhesion durability of the product on the skin and improving the makeup retention.

[0017] Optionally, the film-forming agent is at least one of hydrogenated (styrene / methylstyrene / indene) copolymer, acrylic acid (ester) / polydimethylsiloxane copolymer, acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymer and polymethylsilsesquioxane.

[0018] By adopting the above technical solution, hydrogenated (styrene / methylstyrene / indene) copolymers, etc. can form a uniform thin film on the skin surface, covering the skin surface, which can effectively lock in moisture and oil, increase the adhesion and durability of the highlighter brightening liquid, make the makeup more lasting and natural, and also increase the smoothness and extensibility of the product, making the product easier to push, apply evenly, and be lighter and more breathable.

[0019] Optionally, the colorant includes iron oxide yellow paste and iron oxide red paste in a mass ratio of 3-4:1, the iron oxide yellow paste is a mixture of iron oxide yellow, polyglyceryl-2 triisostearate, triethoxycaprylylsilane and tribehenin, and the iron oxide red paste is a mixture of iron oxide red, polyglyceryl-2 triisostearate, triethoxycaprylylsilane and tribehenin.

[0020] By adopting the above technical scheme, the yellow iron oxide paste and the red iron oxide paste are both made of polyglyceryl-2 triisostearate, triethoxycaprylylsilane and tribehenin, wherein polyglyceryl-2 triisostearate and triethoxycaprylylsilane have good dispersing effects, which can increase the dispersibility of the yellow iron oxide paste and the red iron oxide paste in the highlight brightening liquid, make the color more uniform, and improve the color rendering effect, and polyglyceryl-2 triisostearate has good solubility with other oily ingredients, which can make the color paste better adhere to the skin surface and present a long-lasting makeup effect, and triethoxycaprylylsilane has good wetting properties, which can reduce the surface tension between particles, increase the fluidity and adhesion of the color paste, thereby improving the spreadability of the highlight brightening liquid, making the product easier to spread, and the makeup more long-lasting and stable.

[0021] Optionally, the non-volatile oil is selected from at least one of C12-15 alcohol benzoate, dipropylene glycol dibenzoate, diphenyl dimethicone, diphenylsiloxy phenyl trimethicone, trimethyl pentaphenyl trisiloxane and phenyl trimethicone.

[0022] By adopting the above technical solution, the above non-volatile oils mainly play the role of moisturizing the skin, improving skin elasticity, and enhancing the skin's own barrier function. In addition, they can form a stable emulsion with water molecules, making the product easier to apply and absorb, and providing a refreshing skin feeling.

[0023] Optionally, the non-volatile oil comprises C12-15 alcohol benzoate and trimethyl pentaphenyl trisiloxane in a mass ratio of 1.5:1-1.5.

[0024] By adopting the above technical scheme, C12-15 alcohol benzoate has good solubility and dispersibility, so that the highlight brightening liquid has better spreadability and permeability, and the skin is more refreshed and delicate, overcoming the greasy feeling, making the skin softer and smoother. Trimethyl pentaphenyl trisiloxane has excellent lubricity and smoothness, and improves the texture of the product. It works with C12-15 alcohol benzoate to improve the spreadability and ductility of the highlight brightening liquid on the skin, making the product more lubricated and smooth, easier to apply and push, reducing friction and irritation, and providing a silky touch.

[0025] Optionally, the volatile oil is selected from at least one of isododecane, isohexadecane, cyclopentasiloxane and polydimethylsiloxane; The moisturizing agent is selected from at least one of glycerin, methyl propanediol, butylene glycol, and 1,3-propylene glycol; The stabilizer is selected from at least one of sodium chloride and magnesium sulfate; The preservative is selected from at least one of phenoxyethanol, caprylyl glycol and ethylhexylglycerin.

[0026] By adopting the above technical solution and using isododecane as volatile oil, the spreadability of the highlighter brightening liquid can be improved, the drying and mixing film-forming speed of the product can be accelerated, and the skin can have a nourishing, refreshing and non-greasy skin feel; the moisturizer can enhance the moisturizing ability of the product and improve the stability of the product, the stabilizer can increase the stability of the product, and the preservative can prevent the product from spoiling.

[0027] In a second aspect, the present application provides a method for preparing a highlight brightening liquid, using the following technical solution: A method for preparing a highlight brightening liquid comprises the following steps: According to the amount of raw materials, weigh the raw materials, the non-volatile oils include C12-15 alcohol benzoate and trimethyl pentaphenyl trisiloxane; mix the C12-15 alcohol benzoate and the film-forming agent, heat to 105-110° C., and stir until completely transparent to prepare phase A; Mixing a thickener, trimethyl pentaphenyl trisiloxane and volatile oil to prepare phase B; Mix emulsifier A, emulsifier B, colorant and brightener to prepare phase C; Mix the solvent, humectant, stabilizer and preservative, and heat to 80-85°C to prepare phase D; Add phase B and phase C to phase A in sequence, homogenize, heat to 80-85°C, and set aside to obtain a mixture; The mixture is homogenized, and phase D is added while homogenizing, and then the homogenization is continued to obtain a blended material; The blended material is stirred and cooled, flavor is added, stirred evenly, and discharged.

[0028] By adopting the above technical solution, non-volatile oils are added to phase A and phase B respectively, which can effectively improve the stability of the product and provide a more refreshing skin feel. Moreover, after multiple homogenization, the internal structure and properties of the product are more uniform and consistent, and the overall performance and stability are higher.

[0029] In summary, this application has the following beneficial effects: 1. Since the present application adopts a mixture of bismuth hydroxide, acrolein / acrylic acid copolymer and water as a brightener, and is combined with a colorant to obtain a product with a metallic luster, it can adjust facial dullness, brighten skin tone, and make the skin more delicate and lustrous. Moreover, the mixture of bismuth hydroxide, acrolein / acrylic acid copolymer and water is liquid, which replaces pearl powder, and the prepared product is also a highlight brightening liquid, which reduces the impact of dust on the human body during use, reduces the possibility of allergies, and is safer and more environmentally friendly to use. In addition, the liquid highlight brightening liquid has better adhesion to the skin and will not fall off as easily as pearl powder, thereby obtaining a better and more lasting makeup effect.

[0042] Performance testing Prepare the highlight brightening product according to the above method, and perform performance testing according to the following method: 1. Skin feel evaluation: 10 beauty bloggers were selected to conduct skin feel evaluation with reference to the skin feel evaluation indicators in Table 4. The evaluation results were recorded in Table 5. The test results were taken as the average value of the 10 beauty testers.

[0043] 2. Brightness improvement: Apply the same thickness of the high-gloss brightening liquid prepared in the embodiment and the comparative example on the scraper, place it in an oven at 36.5°C for 1h and 8h, use La colorimeter to test the L (brightness), a, b and △E values ​​at the corresponding time, and calculate the brightness improvement (%). Brightness improvement = Lt / L0×100%, where Lt is the L (brightness) at a certain time, and L0 is the initial L (brightness).

[0044] 3. Durability: 40 adult women (18-40 years old, no limit on skin type) were selected and divided into 20 groups, with 2 people in each group. After normal skin care, highlight brightening liquid was applied on the left and right cheeks. After makeup, the facial brightness L1 of the above makeup testers was tested with a Lab colorimeter. Then, the facial brightness L2 of the above makeup testers was tested again with a Lab colorimeter 8 hours after makeup. The change in facial brightness was calculated according to △L=L1-L2. The larger the △L, the greater the change in brightness and the worse the makeup lasting effect.

[0045] Table 4 Skin feel evaluation index Table 5 Combining the contents of Table 4-Table 5 and Examples 1-3, it can be seen that the prepared highlight brightening liquid has good adherence to the skin after use, and has no irritation, no harm and no side effects to the skin, giving people a comfortable, light and breathable feeling, and has a good effect on skin modification, can brighten the skin tone, improve local dullness, and at the same time, the highlight and brightening effects are more lasting.

[0046] In Example 4 and Example 5, trimethyl pentaphenyl trisiloxane and C12-15 alcohol benzoate in non-volatile oils were not added, while in Example 6, C12-15 alcohol benzoate was used instead of trimethyl pentaphenyl trisiloxane, and in Example 7, trimethyl pentaphenyl trisiloxane was used instead of C12-15 alcohol benzoate. Table 5 shows that the spreadability, smoothness, moisturizing, stickiness and skin-fitting feel of the highlight brightening liquid prepared in Example 4 and Example 5 are not as good as those in Example 1, and after being applied to the face, the brightness of the makeup decreases after 8 hours, the ΔL value changes increase, and the durability of the highlight is weakened. The skin feel evaluation scores of the highlight brightening liquid prepared in Example 6 and Example 7 are improved compared with those in Example 4 and Example 5, but are still not as good as those in Example 1, and the durability of the makeup is insufficient.

[0047] Compared with Example 1, Examples 8 and 9 do not add the mixture of dimethyl silylated silica and isododecane, disteardimethylammonium hectorite and propylene carbonate, respectively. In Example 10, dimethyl silylated silica is replaced by an equal amount. It can be seen that the skin feel score of the highlight brightening emulsion prepared in Examples 8-10 is not as good as that in Example 1, and the makeup effect is not long-lasting.

[0048] Compared with Example 1, Examples 11 and 12 use yellow iron oxide paste and red iron oxide paste in different dosage ratios, and the mass ratio of the colorant and the brightener in Example 13 is changed. The gloss score of the high-gloss brightening liquid prepared in Examples 11-13 decreases.

[0049] Compared with Example 1, Comparative Example 1 uses polyglyceryl-3 diisohydroxystearate instead of polyglyceryl-2 dipolyhydroxystearate, while in Comparative Example 2, polyglyceryl-2 dipolyhydroxystearate is used instead of polyglyceryl-3 diisohydroxystearate. The high-gloss brightening liquid prepared in Comparative Examples 1 and 2 has lower scores in terms of skin-fitting feel and spreadability, and the durability of makeup after application is reduced.

[0050] Compared with Example 1, Comparative Example 3 uses isododecane to replace the non-volatile oil. Compared with Example 1, Comparative Example 4 does not add non-volatile oil. It can be seen from the data in Table 5 that the skin feel evaluation scores of the highlight brightening liquids prepared in Comparative Examples 3 and 4 are reduced, and the makeup lasting effect is worse.

[0051] Compared with Example 1, Comparative Example 5 reduces the amount of brightener used, and Comparative Example 6 changes the amount of colorant and brightener added compared with Example 1. The glossiness of the high-gloss brightening liquid prepared in Comparative Examples 5 and 6 deteriorates.

[0052] Comparative Example 7 is a baked highlighter product prepared by the prior art. Table 5 shows that the evaluation scores of the spreadability, smoothness and glossiness, stickiness and skin-fitting feel of the highlighter product are all reduced, and the △L value is large, the brightness of the makeup changes greatly, and the durability is poor.

[0053] The high-gloss brightening liquid prepared in Example 1 was subjected to quality inspection, and the inspection results were recorded in Table 6. (1) Color: The quality of color determines the application range of beauty products. Take a bottle of sample and visually inspect it in a closed and lightless place to determine whether the color meets the standard. If there is a deviation compared with the standard, it indicates that the property has changed; (2) Fragrance: Each product has its standard fragrance, which is due to the addition of fragrances during preparation. Take a bottle of sample, open the lid, and identify it by smell. It does not smell strange and meets the requirements of the established standards; (3) Appearance: Different types of products have very different standards for appearance. Emulsions present a stable uniform state, without irrelevant substances and stratification, and there will be no separation of oil and water. Take a bottle of sample and observe its appearance with the naked eye in a closed indoor environment to see if it meets the standard specifications; (4) pH: The pH of the skin is slightly acidic, generally between 4.5 and 6.5, and is usually determined by potentiometric method; (5) Thermal stability: Set up an oven Temperature T = ±48℃, take an appropriate amount of fully encapsulated samples and place them in an oven, keep the temperature and humidity constant, take them out after 24 hours, and check whether there is any upper and lower stratification and floating oil; (6) Cold resistance stability: control the temperature of the cooling box at -(5~15)℃, place a small amount of fully encapsulated samples in the cooling box, keep the temperature constant, take them out after 24 hours and wait for the temperature to return to room temperature, and check whether there is any floating oil on the upper layer; (7) Color stability: take two groups of equal amounts of samples and place them in a glass tube, add an amount that accounts for 2 / 3 of the entire length of the glass tube, plug it with a wooden stopper, and place one of the glass tubes to be tested in a constant temperature box, and control the temperature in the box at ±48℃. After 24 hours, compare the color with that of the glass tube placed in the constant temperature box. Table 6 It can be seen that the high-gloss brightening liquid prepared in the present application has a delicate and uniform appearance without precipitation, and has good heat resistance, cold resistance, centrifugation and color stability.
