Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a composition, its use in preparing cosmetics, and cosmetics containing the composition. Background Technology

[0002] Cosmetics often darken after a few hours of application due to factors such as powder migration and aggregation, oil oxidation, and changes in light refraction and scattering after the powder absorbs oil. This is a long-standing and consumer-concerned issue. Common anti-darkening solutions rely on adding powders with high oil-absorbing values. These powders can absorb sebum secreted by the skin, thus reducing the darkening of the base makeup to some extent. However, high oil-absorbing powders tend to have a dry feel and poor spreadability, easily causing problems such as a dry, powdery finish. Currently, achieving a good balance between anti-darkening effects and a smooth feel is difficult and requires further optimization. Therefore, there is a need in this field for a composition that can improve darkening while maintaining a smooth feel. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a composition, its use in preparing cosmetics, and cosmetics containing the composition, which can improve the dullness that occurs after makeup application while ensuring skin feel.

[0004] In view of the above, in a first aspect, the present invention provides a composition comprising: Duck soap tree wax, silicone elastomer polymer, fillers and colorants; The silicon elastomer polymer comprises silica and a silicon elastomer; The average particle size of the silica is 1μm-20μm.

[0005] The unique microcrystalline film-forming properties of soapberry wax enable it to effectively "lock in" silicone elastomers, fillers, and colorants. A double-layered network structure is formed by the soapberry wax and silicone elastomers to encapsulate the fillers and colorants, tightly embedding them within this network. This significantly inhibits their migration and aggregation under the influence of sebum, achieving a synergistic anti-dullness effect in combination with silicone elastomers. Silica, with an average particle size of 1μm-20μm, achieves more uniform dispersion within the silicone elastomers and binds more tightly to the microcrystalline network formed by the silicone elastomers and soapberry wax. This more effectively adsorbs and fixes the oil phase, reducing the migration and aggregation of colorants caused by sebum secretion, while enhancing makeup adhesion and long-lasting matte finish, thus synergistically improving anti-dullness performance. The use of high oil-absorbing powders is reduced, ensuring a smooth skin feel.

[0006] In some specific implementations, the average particle size of the silica is 5μm-15μm.

[0007] In some specific embodiments, the silicon elastomer is selected from one or more of the following: Polysiloxane-11, polydimethylsiloxane crosslinked polymer, or polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer.

[0008] In some specific embodiments, the silicon elastomer polymer further includes one or more of the following: Polydimethylsiloxane, octyl polymethylsiloxane, C13-C16 isoparaffins, or cetyl alcohol.

[0009] In some specific embodiments, based on the total mass of the composition, the mass percentage of the soapberry wax is 5%-15%, the mass percentage of the silicone elastomer polymer is 5%-15%, the mass percentage of the filler is 15%-35%, and / or the mass percentage of the colorant is 35%-75%.

[0010] In some specific embodiments, based on the total mass of the composition, the mass percentage of the soapberry wax is 8%-12%, the mass percentage of the silicone elastomer polymer is 7%-10%, the mass percentage of the filler is 15%-22%, and / or the mass percentage of the colorant is 56%-70%.

[0011] Secondly, the above-described composition is provided for use in the preparation of cosmetics.

[0012] Thirdly, a cosmetic product is provided, comprising the above-described composition.

[0013] In some specific implementations, cosmetics further include one or more of emollients, fillers, colorants, functional agents, thickeners, preservatives, humectants, or emulsifiers.

[0020] The following describes embodiments of this application. The embodiments described below are exemplary and are only used to explain this application, and should not be construed as limiting this application. Where specific techniques or conditions are not specified in the embodiments, they are performed according to the techniques or conditions described in the literature in this field or according to the product instructions.

[0021] definition The term "silicon elastomer polymer" refers to a cross-linked polymer formed by silicon elastomers, which forms a network structure in which silica is uniformly distributed. It does not mean that silica is simply mixed with silicon elastomers.

[0022] Current technologies primarily utilize the addition of powders with high oil-absorbing values ​​to absorb excess oil secreted by the skin, thereby reducing dullness after makeup application. However, these high-oil-absorbing powders have a poor skin feel and poor spreadability, easily causing problems such as a dry, cakey finish and a heavy, powdery appearance. Therefore, a better balance needs to be struck between anti-dullness effects and a smooth skin feel.

[0023] In a first aspect, the present invention provides a composition comprising: Duck soap tree wax, silicone elastomer polymer, fillers and colorants; Among them, silicon elastomer polymers include silica and silicon elastomers; The average particle size of the silica is 1μm-20μm.

[0024] The unique microcrystalline film-forming properties of the soapberry wax enable it to effectively "lock in" silicone elastomers, fillers, and colorants. A double-layered network structure is formed between the soapberry wax and the silicone elastomer, encapsulating the fillers and colorants. This tightly embeds the fillers and colorants within the double-layered network, significantly inhibiting their migration and aggregation under the influence of sebum. This, combined with the silicone elastomer, achieves a synergistic anti-dullness effect. Silica with an average particle size of 1μm-20μm achieves more uniform dispersion within the silicone elastomer and binds more tightly to the microcrystalline network formed by the silicone elastomer and soapberry wax. This more effectively adsorbs and fixes the oil phase, reducing the migration and aggregation of colorants caused by sebum secretion, while simultaneously enhancing makeup adhesion and long-lasting matte finish, thus synergistically improving anti-dullness performance. The reduced content of high oil-absorbing powders ensures a smooth skin feel.

[0025] In some specific implementations, the average particle size of the silica is 1 μm-20 μm. For example, the average particle size of the silica is 1 μm, 2 μm, 5 μm, 10 μm, 20 μm, or any combination of two of these values. Optionally, the average particle size of the silica is 5 μm-15 μm. Silicon elastomer polymers using silica of these particle sizes offer a better balance between anti-dullness and skin feel. The average particle size can be measured using a GRIND GAUGE instrument, which measures the average particle size of the silica in the silicon elastomer polymer.

[0026] In some specific implementations, the silica can also be surface modified. Specifically, it can be treated with polydimethylsiloxane, triethoxyoctylsilane, lecithin, isopropoxytitanium triisostearate, etc.

[0027] In some specific implementations, the silicon elastomer can be any silicon elastomer used in the art. Specifically, one or more of polysiloxane-11, polydimethylsiloxane crosslinked polymer, or polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer can be used. The above-mentioned silicon elastomer raw materials are readily available, which helps to control costs.

[0028] In some specific embodiments, the silicon elastomer polymer also includes a first solvent. This first solvent can be used to dissolve the silica and the silicon elastomer, facilitating their biological functions. The first solvent can be any solvent used in the art that can be used to dissolve the silica and the silicon elastomer. Exemplarily, the first solvent can be one or more of polydimethylsiloxane, C13-C16 isoparaffins, octyl polymethylsiloxane, or cetyl alcohol.

[0029] In some specific implementations, the silicon elastomer polymer includes polydimethylsiloxane, silica, polysiloxane-11, and cetyl alcohol.

[0030] In some specific implementations, the mass percentage of silica, based on the total mass of the silicon elastomer polymer, is 11%-16%. For example, the mass percentage of silica may be 11%, 12%, 13%, 14%, 15%, or 16%, or any range of two of these values. For instance, each 100g of silicon elastomer polymer may contain 11g-16g of silica.

[0031] In some specific implementations, the mass percentage of silicon projectiles is 11%-14% of the total mass of the silicon projectile polymer. For example, the mass percentage of silicon projectiles is 11%, 12%, 13%, 14%, or any range of two of the above values. For instance, each 100g of silicon projectile polymer may contain 11g-14g of silicon projectiles.

[0032] In some specific embodiments, the mass percentage of soapberry wax is 5%-15% of the total mass of the composition. For example, the mass percentage of soapberry wax is 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, or 15%, or any range of two of the above values. Optionally, the mass percentage of soapberry wax is 8%-12% of the total mass of the composition. Using soapberry wax with the above-mentioned mass percentages results in better improvement of dullness. For example, each 100g of the composition of the present invention may contain 5g-15g of soapberry wax, optionally 8g-12g of soapberry wax.

[0033] In some specific embodiments, the mass percentage of the silicone elastomer polymer, based on the total mass of the composition, is 5%-15%. For example, the mass percentage of the silicone elastomer polymer is 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, or 15%, or any range of two of the above values. Optionally, the mass percentage of the silicone elastomer polymer, based on the total mass of the composition, is 7%-10%. Using the above-mentioned mass percentages of silicone elastomer polymer, it tightly bonds with the microcrystalline network of the soapberry wax, enhancing the flexibility and absorbency of the network structure, effectively filling pores and fine lines, and providing a smooth skin feel. For example, each 100g of the composition of the present invention may contain 5g-15g of silicone elastomer polymer, optionally 7g-10g of silicone elastomer polymer.

[0034] In some specific embodiments, the filler comprises 15%-35% of the total mass of the composition. For example, the filler may comprise 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, or 35%, or any range of two of the above values. Optionally, the filler comprises 15%-22% of the total mass of the composition. Using fillers with the above-mentioned mass percentages results in better improvement of dullness. For example, each 100g of the composition of the present invention may contain 15g-35g of filler, optionally 15g-22g of filler.

[0035] In some specific embodiments, the colorant comprises 35%-75% of the total mass of the composition. For example, the colorant may comprise 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, or any range of two of the above values. Optionally, the colorant comprises 56%-70% of the total mass of the composition. Using colorants with the above-mentioned weight percentages, the colorant provides sufficient coverage and an even skin tone, while being effectively encapsulated by saponin wax and silicone elastomers, thereby significantly inhibiting its migration and aggregation on the skin surface, achieving a long-lasting and even makeup effect. For example, each 100g of the composition of the present invention may contain 35g-75g of colorant, optionally 56g-70g of colorant.

[0036] In some specific embodiments, the filler of the present invention may be one or more of lauroyl lysine, boron nitride, mica, muscovite, sericite, phlogopite, synthetic mica, rubicin, or biotite.

[0040] In some specific implementations, the powder may be surface-treated with a surface treatment agent. Surface treatment agents include one or more combinations of amino acids, triethoxyoctylsilane, polydimethylsiloxane, polymethylsiloxane, isopropyltrisethoxytitanium triisostearate, stearic acid, and hydrogenated lecithin.

[0041] Furthermore, the composition also includes an oil phase. For example, one or more combinations of shea butter, babassu seed oil, mango seed butter, cocoa butter, and muruman palm seed butter.

[0042] Furthermore, the composition may also include other components, exemplarily a second solvent for dissolving the other components into a liquid state; exemplarily a carrier for mixing the other components and forming a specific state, such as a solid or fluid state. One or more of these components can be combined to achieve the desired effects of the invention.

[0043] In some specific embodiments, the composition further includes a second solvent, which accounts for 10%-50% of the total composition by mass. Exemplarily, the solvent may account for 15%, 20%, 25%, 30%, 35%, 40%, 45%, or 50% of the total composition by mass.

[0064] First, the soapberry wax and silicone elastomer are stirred and mixed evenly to promote the interweaving of the double network structure. Before the mixture cools down, the powder is added. The gel-like mixture can be fully adsorbed on the powder surface. Finally, after drying and cooling, the dense double network structure formed by the plant oil and silicone elastomer coats the powder surface, which is beneficial to the dispersion of the powder composition in the oil phase and reduces the darkening phenomenon caused by powder aggregation.

[0068] In this formulation, the silicon elastomer polymer II is simply prepared by mixing polydimethylsiloxane, silica, polysiloxane-11, and cetyl alcohol, and the particle size is controlled to 20 μm by three-roll milling.

[0069] Table 2 Serial Number Formula instructions Example 5 The difference from Example 1 is that it uses silicon elastomer polymer II (silicon average particle size 20 μm). Comparative Example 1 The difference from Example 1 is that the product does not contain duck soap tree wax. Comparative Example 2 The difference from Example 1 is that the product does not contain silicon elastomer polymer. Comparative Example 3 The difference from Example 1 is that the product does not contain duck soap tree wax and silicone elastomer polymer. Comparative Example 4 The difference from Example 1 is that the product does not contain duckweed flower wax but contains large-flowered cocoa seed butter. Comparative Example 5 The difference from Example 1 is that it uses silicon elastomer polymer III (silicon average particle size 60 μm). Hydrophobicity test of the composition Detection principle When a drop of test liquid is placed on a sample surface, it forms a contact angle tangent to the solid surface. A larger contact angle indicates greater difficulty in wetting the surface, meaning stronger material repulsion towards the liquid. A higher contact angle also indicates better water and oil resistance.

[0070] Detection steps and result analysis A small amount of the anti-dulling powder composition was pressed into a smooth, flat sheet using a tablet press under specific pressure. The contact angle was measured using a contact angle meter. After calibrating the levelness and droplet injection system, 2-4 μL of distilled water was carefully added to the surface of the powder sheet using a microsyringe. The angle formed by the droplet contacting the powder sheet was observed under a microscope, and the contact angle was measured using image processing software. A high-speed camera instantly captured the droplet morphology, and the instrument software fitted the droplet profile using the Young-Laplace equation, automatically calculating the left and right contact angles and taking the average value. Measurements were repeated at at least three different points, and the average value was taken. The results are shown in Table 3. Table 3 shows that the contact angles of Examples 1-5 are all greater than those of Comparative Examples 1-5. Therefore, the composition of the present invention has better hydrophobicity.

[0071] Table 3 Formula Name Contact angle / ° Example 1 117 Example 2 114.7 Example 3 113.9 Example 4 126.0 Example 5 105.8 Comparative Example 1 87.0 Comparative Example 2 94.6 Comparative Example 3 Liquid inhalation (<90°) Comparative Example 4 93.0 Comparative Example 5 97.2 Testing of the anti-dullness efficacy of the composition Detection principle A colorimeter was used to measure the staying power of foundation cosmetics during makeup performance testing. The most commonly used color representation in the makeup industry is the L*a*b color model. The makeup performance testing process involved applying a certain amount of comparative and experimental samples onto test card paper using a coater to form a 10μm thick film. The L, a, and b values ​​of each sample were measured using an X-Rite Ci6X non-contact spectrophotometer at 1h, 2h, 4h, and 8h, and the color difference value ΔE was calculated. A smaller ΔE value indicates more stable color and better anti-dulling effect.

[0072] Detection steps and result analysis The prepared foundation liquid was dropped onto the surface of black test card paper. A 10 μm layer of foundation liquid was evenly coated onto the surface of the black card paper using a coater. The instantaneous colorimetric values ​​(L, A, and B values) of the foundation liquid coating were measured using an X-Rite Ci6X portable spectrophotometer. The black card paper was left to stand at room temperature, and the colorimetric values ​​of the samples were measured using a spectrophotometer at fixed times (1 h, 2 h, 4 h, 8 h). The difference between the three colorimetric values ​​(L, A, and B values) at different times was calculated and recorded as ΔE. Each sample was tested in triplicate, and the average value of the three measurements was taken. The results are shown in Table 4. The ΔE values ​​of Examples 1-5 at 1 h, 2 h, 4 h, and 8 h were all smaller than those of Comparative Examples 1-5, indicating that the anti-dulling effect of the composition of the present invention is far superior to that of the comparative compositions.

The target groups were 5 with dry skin, 5 with oily skin, and 5 with combination skin.

[0074] Test Method: Subjects cleansed their entire face with facial cleanser and sat quietly in a temperature- and humidity-controlled room for 20 minutes. After applying a foundation sample to the face, the powdery feel of the makeup was rated immediately after application, at 4 hours, and at 8 hours (0-5 points: 0-1 point: natural makeup effect, almost no powdery feel; 1-2 points: slight powdery feel; 2-3 points: noticeable powdery feel, but acceptable; 3-4 points: obvious makeup effect, mask-like or powdery feel; 4-5 points: very heavy makeup effect, strong mask-like feel, obvious powdery feel). The ratings were collected and averaged, and the test results are shown in Table 6. As can be seen from Table 6, the makeup scores of Examples 1-5 are much lower than those of Comparative Examples 1-5. This indicates that the composition of the present invention has a better skin feel.
