Description

Technical Field

[0001] The present application relates to the field of cosmetics, and in particular to a matte lip mud and a preparation method thereof. Background Art

[0002] As an emerging lip makeup product, lip mud has a soft and dense texture that is between solid lipstick and liquid / fluid lip glaze. It has the characteristics of strong coloring power and high color saturation, perfectly meeting the needs of the new generation of consumers and has great market potential.

[0003] Traditional lip mud is easy to fade and become mottled, which makes it difficult to meet the demand for long-lasting beauty. If a matte effect is added, the lip gloss product will have poor durability, dry lips and even cracking during use, which will affect the user experience. Although this situation can be improved by increasing the proportion of oil or adding moisturizing ingredients, over-reliance on oil will sacrifice the matte effect and make the product lose its matte effect. In addition, adding a large amount of water or oil also increases the risk of product contamination and reduces the shelf life of the product.

[0004] Therefore, there is an urgent need in this field to develop a new type of matte lip mud that can simultaneously meet the requirements of skin-fitting, long-lasting and matte effects. Summary of the invention

[0005] The purpose of the present application is to provide a matte lip mud and a preparation method thereof, which can simultaneously meet the requirements of skin-fitting, long-lasting and matte effects.

[0006] In the first aspect, the present application provides a matte lip mud, which adopts the following technical solution: A matte lip mud, characterized in that it comprises the following components in percentage by mass: 20-25% of a first silicone elastomer, 30-40% of a second silicone elastomer, 15-20% of a stabilizer, 3-5% of a colorant, and 25-35% of an auxiliary agent, wherein the auxiliary agent is selected from one or more of an emollient, a thickener, an antioxidant, a preservative, a film former, and a solvent; the first silicone elastomer is composed of polydimethylsiloxane and a vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer; the second silicone elastomer is composed of polydimethylsiloxane and a polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer.

[0007] By adopting the above technical solution, the silicone elastomer is divided into two parts, solving the problem that the silicone elastomer is not easy to disperse. At the same time, the silicone elastomer with a specific composition is used to enhance the cohesion between the components, so that no clumping or residue falling occurs during use. It adheres tightly to the skin and works in conjunction with other emollients and thickeners to help the matte lip mud to be evenly applied.

[0008] Optionally, the mass percentage of the first silicone elastomer and the second silicone elastomer does not exceed 60%.

[0009] By adopting the above technical solution, an appropriate amount of silicone elastomer is selected, and through its adsorption of grease, the matte degree of the product increases with the increase of its content within the preferred range of the present application. However, when its content exceeds the preferred range of the present application, the adsorbed grease content is too high, which leads to a decrease in spreading degree and then a decrease in matte degree.

[0010] Optionally, the mass ratio of polydimethylsiloxane to vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer in the first silicone elastomer is 2-3:1.

[0011] Optionally, the mass ratio of polydimethylsiloxane to polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer in the second silicone elastomer is 3-4:1.

[0012] By adopting the above technical solution, the components in the silicone elastomer in a specific proportion work together to better absorb oil and fat, and help to evenly distribute the components, resulting in better matte effect and skin-fitting performance.

[0013] Optionally, the stabilizer is selected from the group consisting of lauryl PEG-9 polydimethylsiloxyethyl dimethicone containing tocopherol and silica.

[0014] Optionally, the stabilizer consists of 2.0% lauryl PEG-9 polydimethylsiloxyethyl dimethicone containing 0.02% tocopherol and 15% silica.

[0015] By adopting the above technical solution, the use of antioxidants combined with stabilizers can further improve skin feel and reduce the amount of a single ingredient, thereby improving safety.

[0016] Optionally, the colorant is selected from the group consisting of CI 15850, CI 77491, CI 77891, and CI 77499.

[0017] Optionally, the emollient and / or thickener is selected from the group consisting of tribehenin, polyglyceryl-2 triisostearate, diisostearyl malate, sorbitan sesquiisostearate and methyl methacrylate crosspolymer.

[0018] Optionally, the matte lip mud also includes flavonoids extracted from chrysanthemum.

[0019] By adopting the above technical scheme, the components work synergistically to further increase the skin-fitting, long-lasting and matte effects; in particular, the first silicone elastomer and the methyl methacrylate cross-linked polymer can undergo copolymerization and cross-linking, so that the lip mud forms a layer of network cross-linked structure film on the surface of the lips, which can lock in the effective ingredients, prolong the residence time of the effective ingredients on the skin, and achieve a longer-lasting makeup effect.

[0020] In a second aspect, the present application provides a method for preparing a matte lip mud, using the following technical solution: S1: Add the raw material auxiliary agent and stabilizer into the melting pot, stir and heat to 70-75℃ to mix the materials evenly; S2: Put the raw material first silicone elastomer, auxiliary agent and stabilizer into the melting pot, keep warm at 70-75℃ and stir evenly; S3: Mix the raw colorant with the above mixture, grind 3-4 times, check the grinding fineness of the color powder, put it back into the melting pot, and mix well at 65-70℃; S4: Keep the melting pot at 65-70℃, put the raw material second silicone elastomer and auxiliary agent into the melting pot and mix well; S5: After matching and adjusting the colors, slowly stir and cool down to below 35°C and remove from the pan.

[0021] By adopting the above technical solution, the colorant is wrapped by the silicone elastomer raw material in two steps, and the colorant can be fully mixed and dispersed, so that the silicone elastomer can carry more colorant, thereby enhancing the makeup lasting longer.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The matte lip mud of the present application has a good skin-adhering effect; 2. The matte lip mud of the present application is long-lasting; 3. The matte lip mud of the present application has a good matte effect. DETAILED DESCRIPTION

The result obtained is the ratio R between specular reflection and diffuse reflection (gloss units or GU). The smaller the R value, the greater the matte effect. The gloss evaluation scale 1 is as follows: Table 1 2. Persistence test The thickness of the lip film was measured over a total time of 8 hours. 8H The film thickness is measured under the condition of 8H The test results are shown in Table 2.
