[0047] Compared with the prior art, this application has at least the following beneficial effects:

[0048] (1) The matte lip gloss provided in this application has a matte lip makeup effect, a very delicate and moisturizing texture, is light and easy to spread, adheres very well to the skin, has high color saturation, strong coverage, does not reflect light, has even color, and does not transfer to cups; in addition, it is relatively long-lasting and has good moisturizing and hydrating effects, does not dry out the skin, and has good makeup retention and high safety, making it very friendly to pregnant women and users with sensitive skin.

[0051] Figure 1 The image shown is a product photo of the matte lip gloss of the embodiment;

[0052] Figure 2 The image shows lips coated with the matte lip gloss of the embodiment. Detailed Implementation

[0053] To make the purpose, technical solution, and beneficial technical effects of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0054] For simplicity, this application only explicitly discloses some numerical ranges. However, any lower limit can be combined with any upper limit to form a range not explicitly stated; and any lower limit can be combined with other lower limits to form a range not explicitly stated, just as any upper limit can be combined with any other upper limit to form a range not explicitly stated. Furthermore, although not explicitly stated, every point or individual value between the endpoints of the range is included within that range. Therefore, each point or individual value can be used as its own lower or upper limit and combined with any other point or individual value or with other lower or upper limits to form a range not explicitly stated.

[0055] In the description of this application, it should be noted that, unless otherwise stated, "above" and "below" include the stated number, and "multiple" in "one or more" means two or more.

[0056] The foregoing description of this application is not intended to describe every disclosed implementation or method. Instead, the following description provides more specific examples of exemplary embodiments. Throughout the application, guidance is provided through a series of embodiments that can be used in various combinations. The examples listed are representative only and should not be construed as exhaustive.

[0057] As lip cosmetics continue to develop, people's requirements for products are also getting higher and higher. In addition, with the ongoing impact of the pandemic, people need to wear masks every day, which makes it extremely easy to ruin lip makeup or stain the mask.

[0058] Lip cosmetics include lip gloss, lipstick, and lip tint. Currently, lip glosses sold on the market are divided into four main types: oil-dispersed, oil-in-water, water-in-oil, and aqueous. Each formulation has its own advantages and disadvantages.

[0059] For example, oil-dispersed lip glosses have excellent moisturizing properties and high color payoff, but they dry slowly, have a noticeable powdery feel, and lack staying power; water-in-oil lip glosses dry quickly and have a noticeable non-transfer effect, but they can cause dryness and accentuate lip lines after forming a film; water-in-oil and water-based lip glosses are long-lasting and do not fade, but they can stain the lips, and the added alcohol evaporates and takes away moisture from the lips, making them drier the more you use them.

[0060] Based on this, the inventors conducted extensive research and discovered that specific filler powders and film-forming agents can be selected to improve the matte finish and anti-transfer ability of lip gloss. In turn, the synergistic effect of each component gives the matte lip gloss excellent moisturizing and lightweight properties.

[0061] Matte Lip Gloss

[0062] In a first aspect, embodiments of this application provide a matte lip gloss, comprising the following components by weight:

[0063] The oil phase matrix component, 100 parts, comprises a polyglycerol emulsifier, a first organic filler, a film-forming agent, and an oil phase solvent, wherein the first organic filler is a mixture of polydimethylsiloxane and a polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer, and the film-forming agent is a mixture of trimethylsiloxysilicate, acrylic / polytrimethylsiloxane methacrylate copolymer, and polymethylsilsesquioxane;

[0064] Aqueous matrix component, 25.0–60.0 parts, comprising water, polyol, metal chelating agent and preservative;

[0065] The color paste component, 12.5–40.0 parts, comprises color powder and color powder dispersant, wherein the average particle size Dv90 of the color powder is 10–50 μm; and

[0066] Second filler powder, 6.25 to 20.0 parts.

[0067] According to the embodiments of this application, after the oil phase matrix component, water phase matrix component and pigment component are fully mixed in the above mass ratio, an appropriate amount of second filler powder is added to adjust its concentration. The components interact with each other to make the lip gloss of this application have a matte finish.

[0068] The skin on the lips is only one-third the thickness of that on the cheeks, and because the lips do not have sebaceous glands, they are the most prone to dryness and cracking. The matte lip gloss in this application contains a high proportion of oil-phase matrix components, which ensures continuous moisturization after application. Furthermore, the first organic filler and film-forming agent are distributed in the oil-phase matrix components, which can further improve the skin-adhering breathability and film-forming effect of the matte lip gloss.

[0069] The average particle size Dv90 of the pigments is within the above range, which is beneficial for controlling the uniformity of color and reducing their migration in the lip gloss, especially in the oil phase matrix component. The above particle size was determined using a Malvern Panaco Malvern particle size analyzer (model: Mastersizer 3000 laser diffraction particle size analyzer).

[0070] According to embodiments of this application, the film-forming agent is a mixture of methylsiloxysilicate, acrylic / polytrimethylsiloxane methacrylate copolymer, and polymethylsilsesquioxane. The film-forming agent with the above characteristics can impart a matte finish to the lip gloss of this application, while also improving its non-stickiness. Trimethylsiloxysilicate, being a silica-based substance, can improve the dispersibility of powder in the matte lip gloss and enhance its water resistance, thereby improving its anti-transfer ability. It can be formed into a film-forming agent, and this component is refreshing and non-sticky. The acrylic / polytrimethylsiloxane methacrylate copolymer has thickening, film-forming, and anti-caking effects. Polymethylsilsesquioxane is opaque and can enhance the spreadability and smoothness of cosmetics, improve the smooth skin feel, gloss, powdery feel, and soft-focus effect, giving the matte lip gloss a delicate texture, preventing clumping, smoothing the surface, and enhancing the tactile feel.

[0071] In some embodiments, the matte lip gloss comprises the following components by weight:

[0072] Oil phase matrix component, 100 parts;

[0073] Aqueous matrix component, 30.0–50.0 parts, comprising water, polyol, metal chelating agent and preservative;

[0074] Pigment component, 20.0–30.0 parts; and

[0075] The second filler powder is 8.0 to 15.0 parts.

[0076] In some embodiments, the weight-average molecular weight of polydimethylsiloxane is 5000-1000.

[0077] In some embodiments, the viscosity of polydimethylsiloxane is 100-1500 cs.

[0078] In some embodiments, the weight-average molecular weight of the polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer is 1000-10000.

[0079] In some embodiments, the viscosity of polydimethylsiloxane and polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer is 300-10000 cs.

[0080] According to the embodiments of this application, the addition of the above-mentioned specific weight-average molecular weight and viscosity of polydimethylsiloxane and the mixture of polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer gives the lip gloss lubrication, softness and UV resistance, as well as good breathability and dustproof function; in addition, the main powder in this application is the first organic filler, which, under the combined action of other components, can give the lip gloss of this application a matte finish, while improving its moisturizing and non-drying effect.

[0081] In some embodiments, the mass ratio of polydimethylsiloxane to the polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer is (0.2-0.5):1.

[0082] According to the embodiments of this application, by controlling the mass ratio of polydimethylsiloxane and polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer, the skin-adhering breathability and moisturizing properties of matte lip gloss can be adjusted, further improving the moisturizing and non-drying effect.

[0083] In some embodiments, the mass ratio of trimethylsiloxysilicate, acrylic / polytrimethylsiloxane methacrylate copolymer, and the polymethylsilsesquioxane is (0.1-0.5):(0.2-0.4):1. This can further improve the film-forming effect of the matte lip gloss.

[0084] In some embodiments, the mass ratio of the first organic filler to the film-forming agent is (2-7):1. The above-mentioned mass ratio of the first organic filler to the film-forming agent can further improve the moisturizing, skin-adhering, breathable, and non-transfer effects of the matte lip gloss.

[0085] In some embodiments, the matte lip gloss also includes a softener. The softener is selected from glycolipids and polyglycerol-2 triisostearate, which can further improve the moisturizing, fluidity and spreadability of the matte lip gloss, and ensure its excellent skin adhesion and high-quality feel.

[0086] In some embodiments, the polyglycerol emulsifiers include one or more of the following: polyglycerol-4-isostearate, polyglycerol-3-diisostearate, polyglycerol-2-dipolyhydroxystearate, polyglycerol-2-isostearate, polyglycerol-2-oleate, polyglycerol-3-cocoate, polyglycerol-3-polyricinoleate, polyglycerol-6-polyricinoleate, polyglycerol-6-didecanoate, polyglycerol-10-dioleate, polyglycerol-10-caprylic / capric glyceride, and polyglycerol behenate / eicosanoate; and / or, combinations thereof.

[0087] In some embodiments, the oil phase matrix component further includes cetyl PEG / PPG-10 / 1 polydimethylsiloxane.

[0088] In some embodiments, the matte lip gloss meets at least one of the following conditions:

[0089] The oil phase solvent is selected from isohexadecane, octyldodecyl alcohol, caprylic / capric triglyceride or a combination thereof; when preparing matte lip gloss, the oil phase solvent can promote the compatibility of moisturizing oils and other components with other components. After the matte lip gloss is applied, a certain amount of oil phase solvent will evaporate, promoting the film formation of the matte lip gloss and enhancing its makeup-holding performance.

[0090] The polyols are selected from glycerin, 1,2-hexanediol, butylene glycol, 1,3-propanediol, 1,2-pentanediol, caprylyl glycol or combinations thereof; the above polyols can improve the moisturizing properties of matte lip glosses.

[0091] The metal chelating agent is selected from ethylenediaminetetraacetic acid, disodium ethylenediaminetetraacetic acid, or a combination thereof. When an organosilane polymer is added to a matte lip gloss, adding an appropriate amount of metal chelating agent can chelate some of the ions in the organosilane polymer, thereby improving the safety and comfort of the matte lip gloss.

[0092] Preservatives are selected from phenoxyethanol, octyl glycol, pentylene glycol, 1,2-hexanediol, glyceryl caprylate, or combinations thereof. To prevent quality degradation caused by microbial contamination and thus further extend the product's shelf life, a certain amount of preservative can be added to inhibit the growth and reproduction of microorganisms. Furthermore, using different types of preservatives can achieve better preservative effects.

[0093] In some embodiments, the pigment is selected from titanium dioxide, iron oxide red, red 7, iron oxide yellow, acid blue 9, or a combination thereof.

[0094] In some embodiments, the colorant dispersant is selected from cetyl PEG / PPG-10 / 1 polydimethylsiloxane, polyglycerol-2 triisostearate, or a combination thereof.

[0095] According to the embodiments of this application, the color powder can be matched and adjusted according to different matte lip gloss color requirements. By adjusting the type and proportion of different coloring powders, different colored coloring powders can be obtained, so that the matte lip gloss has a specific color or color number.

[0096] In some embodiments, the color powder dispersant is selected from cetyl PEG / PPG-10 / 1 polydimethylsiloxane, polyglycerol-2 triisostearate, or combinations thereof. According to embodiments of this application, adding a certain amount of powder dispersant can uniformly disperse the color powder in the color paste, subsequently effectively dispersing it in the oil phase matrix component. This results in good color dispersibility for the matte lip gloss, allowing it to form a uniformly distributed film after application. Simultaneously, it reduces the transfer properties of the matte lip gloss, reducing or eliminating the problem of sticking to cups.

[0097] The second filler powder is selected from inorganic powder, organic powder, or a combination thereof.

[0098] According to the embodiments of this application, the first organic filler, pigment, and second filler powder work together to give the lip gloss a matte finish.

[0099] In some embodiments, the inorganic powder is selected from kaolin, barium sulfate, talc, or combinations thereof.

[0100] In some embodiments, the organic powder is selected from vinyl polydimethylsiloxane / polymethylsilsesquioxane crosslinked polymers, polytrimethylsiloxane, or combinations thereof.

[0101] In some embodiments, the oil phase matrix component further comprises a humectant, which may be selected from one or more of glycerin, propylene glycol, and 1,3-butanediol. The humectant can absorb moisture from the environment and replenish the skin, increasing the skin's surface hydration and thus enhancing the long-lasting moisturizing effect of the matte lip gloss.

[0102] In some embodiments, the oil phase matrix component further comprises a suspending agent, wherein the suspending agent is distearate dimethylammonium lithium montmorillonite. This can improve the dispersibility of the powder.

[0103] In some embodiments, the matte lip gloss comprises the following components in parts by weight:

[0104] The oil phase matrix component, 100 parts, comprises 4.375-12 parts emulsifier, 2.5-10 parts emulsifier, 25-70 parts first organic filler, 0.625-2 parts suspending agent, 6.25-20 parts film-forming agent, 25-80 parts oil phase solvent, and 0.125-1.4 parts humectant. The first organic filler is a mixture of polydimethylsiloxane and a polydimethylsiloxane / vinyl polydimethylsiloxane crosspolymer. The film-forming agent is a mixture of trimethylsiloxysilicate, acrylic / polytrimethylsiloxane methacrylate copolymer, and polymethylsilsesquioxane.

[0105] The aqueous matrix component, 25.0–60.0 parts, includes 11.25–40 parts water, 3.75–20 parts polyol, 0.025–0.1 parts metal chelating agent and 0.625–2 parts preservative;

[0106] The color paste component, 12.5–40.0 parts, comprises 3.75–20 parts color powder and 3.75–20 parts color powder dispersant, wherein the particle size Dv90 of the color powder is 10–50 μm; and

[0107] Second filler powder, 6.25 to 20.0 parts.

[0108] According to the embodiments of this application, the matte lip gloss provided by this application has a delicate texture, high gloss and uniform color, good moisturizing, hydrating and lightweight effects, high safety, does not transfer to cups, and is also very friendly to users with sensitive skin.

[0114] Under heating conditions, the first mixture is mixed uniformly with the aqueous matrix component to obtain the second mixture;

[0115] The second mixture is mixed evenly with the second filler powder to obtain a matte lip gloss.

[0116] According to the embodiments of this application, the second mixture and the second filler powder are mixed evenly, which can adjust the powder content in the matte lip gloss, thereby effectively controlling the powder ratio and further improving the matte and other makeup effects.

[0117] In some embodiments, the preparation method satisfies at least one of the following conditions:

[0166] Test section

[0167] 1) Human patch test (irritation test)

[0168] The purpose of the test is to detect the possibility that the sample may cause adverse reactions on human skin.

[0169] The experimental equipment includes: a plaque tester, and a medical device [Approval Number]: Beijing Drug Administration Medical Device (Approval) No.

[0170] No. 1640520, 2011.

[0171] The basic principles of the experiment include:

[0172] (1) Select qualified volunteers as experimental subjects;

[0173] (2) Conduct human patch tests using specially made patch materials;

[0174] (3) Sample processing and testing shall be carried out in accordance with the methods of "General Principles for Diagnosis and Treatment of Cosmetic Dermatological Diseases" (GB 17149-1-1997).

[0175] Subject selection:

[0176] (1) Select volunteers aged 18-40 who meet the experimental criteria as subjects;

[0177] (2) Individuals with the following conditions should not be selected as subjects;

[0178] (3) Those who have used antihistamines in the past week or immunosuppressants in the past month;

[0190] (15) Those who are not volunteers or who are unable to complete the prescribed content in accordance with the test requirements.

[0191] The grading criteria for adverse skin reactions are shown in the table below (Table 1):

[0192] Table 1 Grading Criteria for Adverse Skin Reactions in Patch Testing

[0193] Adverse skin reactions Classification No response 0 Light red spots 1 Erythema, infiltration, papules 2 Erythema, edema, papules, vesicles 3 Erythema, edema, bullae 4

[0194] Test method:

[0195] (1) There were 30 volunteers who participated in the test;

[0196] (2) Select a suitable patch material and place the sample into the patch, using approximately 0.03 mL; the control well is a blank control (containing no substances). Apply the patch containing the sample to the inner forearm of the volunteer using non-irritating adhesive tape, with one side as the control area and the other side as the test area. Press the patch evenly onto the skin with your palm and leave it for 24 hours (the time can be adjusted according to the actual situation).

[0197] (3) After removing the patch from the volunteers, observe the skin reaction 30 minutes later, once the indentation has disappeared. If the result is negative, observe again at 24h and 48h after the patch test. Record the reaction results according to the skin reaction grading standard in Table 2. If the product results are negative after observing again at 24h and 48h, the product effectiveness assessment is carried out, and the test results in Table 2 are shown below:

[0198] Table 2 shows the patch test results of the four matte lip glosses in the examples on 30 subjects (rated according to the skin reaction grading standard, with grade 0 indicating safe and non-irritating).

[0199] sample Test results Example 1 30 Level 0 Example 2 30 Level 0 Example 3 30 Level 0 Example 4 30 Level 0 Example 5 30 Level 0

[0200] As shown in Table 2 above, the matte lip glosses of Examples 1 to 5 are almost non-irritating, indicating that the matte lip glosses provided in this application have low irritation and high safety performance.

[0201] 2) Performance test of matte lip gloss

[0202] The matte lip glosses of the examples and comparative examples were subjected to performance tests related to their use.

[0203] 1) Moisture blocking: This occurs when water enters the glass sample vial (opening). 10 cc of water was added to the sample vial, and the sample was coated onto one side of filter paper (Toyo Filter Paper Co., Ltd., membrane filter, 0.2 μm pore size) to a thickness of 25 μm, covering the opening. The weight loss (moisture loss) of the sample vial after standing at 30°C and 30% RH for 12 hours was measured. The moisture blocking property was calculated by comparing the weight loss with that of the uncoated filter paper.

[0204] Moisture blocking property (%) = (1 - [moisture reduction when sample is coated / moisture reduction when sample is not coated]) × 100

[0205] (2) Color quality: A panel of 10 members conducted a sensory evaluation of the color quality of each lip cosmetic immediately after application to the lips and 3 hours later. The evaluation is expressed by the number of panel members who rated it as good.

[0206] (3) Stickiness: A panel of 10 members evaluated the stickiness of each lip cosmetic immediately after application and 3 hours later. The number of panel members who rated it as good is used to indicate the presence or absence of stickiness.

[0207] (4) Dryness sensation: A panel of 10 members evaluated the dryness sensation immediately after applying each lip cosmetic to the lips and 3 hours later. The evaluation was expressed as the number of panel members who rated it as good.

[0208] (5) Matte finish: Matte finish rating: '1' indicates a matte finish, '0' indicates no matte finish.

[0209] The test results for the matte lip glosses in the examples and comparative examples are shown in the table below.

[0210] Table 3

[0211]

[0212]

[0213] The test results above show that the matte lip glosses of Examples 1-5 have low water-blocking properties, good color payoff, and strong staying power. After applying the matte lip glosses, there is no dryness or stickiness, and they have a matte finish. In contrast, the comparative examples have a stronger dryness and stickiness, indicating that the products of the examples have good application effects.

[0214] The matte lip gloss of Example 1, such as Figure 1 As shown, the effect of applying the matte lip gloss of Example 1 to the lips is illustrated. Figure 2 As shown in the figure, matte lip gloss has a good matte finish and does not accentuate lip lines.

[0215] 3) Lip line coverage test

[0216] Testing instrument: Antera 3D (Miravex, Ireland)

[0217] Test subject: Artificial leather

[0218] Test method: 1. Clean the artificial leather with a wet wipe and mark 10 fixed areas of 2cm×2cm on the artificial leather;

[0219] 2. Use Antera 3D to measure the texture of a fixed area, record the Ra and Rq values, and take the average value;

[0220] 2. Apply 0.3g of test sample evenly to the designated area;

[0221] 3. Use Antera 3D to measure the texture of the fixed area after applying the product, record the Ra and Rq values, and take the average value. The results are shown in Table 4.

[0222] Parameter explanation:

[0223] Ra: Average roughness, disregarding the vertical direction, evaluates an average of all deviations from a straight line over a length;

[0224] Rq: Root mean square roughness, which is the root mean square average of the roughness ordinate.

[0225] Table 4

[0226]

[0227]

[0228] As can be seen from the test data of Examples 1-5 and Comparative Examples 1-6, the first filler and film-forming agent of this application have a certain effect on covering lip lines. However, when one or more of them are missing, the viscosity of the matte lip gloss and the dispersion uniformity of the components are changed, and thus its covering effect will decrease to a certain extent, possibly due to a decrease in its spreadability.

[0229] As can be seen from the test data of Examples 1-5 and Comparative Examples 1-6, the first filler and film-forming agent have the effect of helping to cover lip lines. The increase of their content within the preferred range of the present invention has a more obvious effect on improving the coverage of lip lines, especially the effect of vertical lip line coverage. The reason may be that they can penetrate into the deep texture better.

[0230] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
