[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0030] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0031] Eye shadow is a cosmetic product applied on the eyelids and corners of the eyes to produce shadows and color contrasts, showing a three-dimensional aesthetic feeling, strengthening the eyes, and making the eyes look beautiful. The formula of eye shadow is similar to that of foundation, but the color is richer and often has an extra luster, and generally a variety of coloring powders and pearlescent powders are added. As described in the background technology section, the main dosage forms of eye shadow include powdery and ointments. Among them, powdery eye shadow is based on powder components, a small amount of other components are added, and it is formed by compression. Its advantages are that it is easy to carry and easy to use, and it is easy to get a suitable makeup by dyeing, but the disadvantages are also obvious. In addition to the obvious disadvantage of easy powder flying, the colorability is also poor. In addition, the powdery eye shadow has very high requirements for the type and particle size of the powder component, which will increase the production cost. Although the ointment eye shadow overcomes the shortcomings of the powdery eye shadow, it also brings new problems. Because the powder components in the eye shadow need to be stably dispersed, more oil components with higher viscosity are needed, which will make the ointment eye shadow sticky and the ductility will also become poor. Especially when the eye shadow is used on the eyelids and corners of the eyes, the discomfort caused by the stickiness will be very obvious.

[0032] With regard to the above problems, the inventor has made improvements to the above solutions after in-depth thinking, and provided an elastic pearlescent eyeshadow paint that can overcome the defects of the above two eyeshadows at the same time, and produce an elastic pearlescent eyeshadow paint that does not fly powder or slag, has good colorability and good ductility. The elastic pearlescent eyeshadow paint of the present application is described in detail below.

[0033] In order to solve the problems of the prior art, the embodiment of the present application provides an elastic pearlescent eyeshadow paint and a preparation method thereof. The elastic pearlescent eyeshadow paint provided by the embodiment of the present application is first introduced below.

[0034] In the first aspect, an embodiment of the present application provides an elastic pearlescent eye shadow paint, which is composed of the following components in percentage by mass: a powder component: 55% to 64%, the powder component includes a filling powder and a pearlescent powder; an oil component: 36% to 45%, the oil component includes polyisobutylene and an oil mixture, and the oil mixture is a mixture of polydimethylsiloxane / polydimethylsiloxane cross-linked polymer and isononyl isononanoate.

[0035] The elastic pearlescent eyeshadow paint in the embodiment of the present application is prepared by controlling the ratio between the powder component and the oil component in the elastic pearlescent eyeshadow paint within the above-mentioned limited range, and by controlling the specific composition of the oil component, so as to obtain an elastic pearlescent eyeshadow paint with no flying powder and slag, good colorability and good ductility.

[0036] The appearance of the elastic pearlescent eyeshadow paint in one embodiment of the present application is as follows Figure 1 As shown, it is orange-yellow pearlescent. The elastic pearlescent eyeshadow paint of this embodiment is as follows after use Figure 2As shown, it can be applied evenly and stably on the skin of the arm without any flying powder or residue, and has good colorability and ductility.

[0037] In some embodiments of the present application, the mass ratio of the filling powder to the pearlescent powder is 1:(6.6-37).

[0038] In the elastic pearlescent eyeshadow paint of the embodiment of the present application, the ratio between the powder component and the oil component in the eyeshadow is mainly controlled within a limited range, wherein the powder component includes filler powder and pearlescent powder, which are mainly dispersed in the system in a solid form. The main function of the powder component is to provide color and additional gloss by being dispersed in the eyeshadow, and it is the main component in the eyeshadow. The main function of the oil component is to combine and stabilize the powder component in the eyeshadow, so that the eyeshadow can be flexibly and evenly applied to the eye area.

[0039] In some embodiments of the present application, the filler powder is vinyl dimethicone / methicone silsesquioxane crosspolymer.

[0040] In some embodiments of the present application, the vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer has a CAS number of 1004791-75-6. For example, at least the vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer purchased from Xinyue Silicone International Trading (Shanghai) Co., Ltd. with a trade name of KSP-101 can be selected. Among them, the vinyl polydimethylsiloxane is abbreviated as Vi-PDMS, and the polymethylsiloxane silsesquioxane cross-linked polymer can be abbreviated as PMDS.

[0041] In the elastic pearlescent eyeshadow paint of the embodiment of the present application, the filling powder component is solid at room temperature, and its main function is to improve the stability of the powder component in the eyeshadow, increase the smoothness of the skin, make the skin delicate and the makeup fit. Among them, the vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosslinked polymer can play a certain effect of adjusting the skin feel of the eyeshadow and improve the uniformity of the eyeshadow. And make the elastic pearlescent eyeshadow paint smooth and easy to push, reduce the sticky feeling, and provide users with a smooth and comfortable use experience. It is understandable that the present application is adjusted accordingly according to actual needs, and other ingredients can be further added as filling powders on the basis of the above components, all within the scope of protection of the present application.

[0042] In some embodiments of the present application, the pearlescent powder is prepared by compounding calcium aluminum borosilicate, titanium dioxide, synthetic fluorphlogopite, tin oxide and coloring pigments.

[0043] In the embodiments of the present application, the pearlescent powder is mainly used to increase the brightness of the eye shadow and to adjust the color of the eye shadow.

[0044] In some embodiments of the present application, the pearlescent powder consists of 38.7 wt.% to 41.7 wt.% of the first mica pearlescent mixture, 38.7 wt.% to 41.7 wt.% of the second mica pearlescent mixture, and 16.7 wt.% to 22.5 wt.% of the glass pearlescent mixture.

[0045] In the embodiment of the present application, the first mica pearlescent mixture and the second mica pearlescent mixture are selected to be compounded, which can effectively adjust the color, colorability and ductility of the elastic pearlescent eyeshadow paint. And the pearlescent powder compounded with the glass pearlescent mixture can enhance the brightness of the elastic pearlescent eyeshadow paint, with large particle size but shining luster.

[0046] In the embodiment of the present application, the use of synthetic fluorphlogopite can increase the brightness of the elastic pearlescent eyeshadow paint and enhance the visual effect. In addition, calcium aluminum borosilicate can increase the luster of the eyeshadow, has a blurring effect and a light protection effect, and can effectively achieve a smudge effect on the eyeshadow; in addition, calcium aluminum borosilicate has a low oil absorption effect, which can effectively regulate the oil secreted by sebum and improve the durability of the eyeshadow. Calcium aluminum borosilicate can also effectively weaken wrinkles and blemishes, making the skin tone more even.

[0047] In some embodiments of the present application, the first mica pearlescent mixture is composed of synthetic fluorphlogopite and color-imparting pigment in a mass ratio of 45.2:54.8.

[0048] In some embodiments of the present application, the first mica pearlescent mixture consists of synthetic fluorphlogopite and red iron oxide in a mass ratio of 45.2:54.8.

[0049] For example, the first mica pearlescent mixture can be purchased from Fujian Kuncai Material Technology Co., Ltd., with the trade name: COSMI 820-M1 Desert Orange.

[0050] In some embodiments of the present application, the second mica pearlescent mixture consists of synthetic fluorphlogopite and color-imparting pigment in a mass ratio of 44.3:55.7.

[0051] In some embodiments of the present application, the second mica pearlescent mixture is composed of synthetic fluorphlogopite and red iron oxide in a mass ratio of 44.3:55.7. For example, the second mica pearlescent mixture can be purchased from Fujian Kuncai Material Technology Co., Ltd., with a trade name of COSMI 820-M2 Solar Orange.

[0052] In one embodiment of the present application, the CAS number of synthetic fluorphlogopite is 12003-38-2. The coloring pigment is red iron oxide, i.e., ferric oxide, and its CAS number is 1309-37-1. Figure 1 and Figure 2As shown, red iron oxide as a coloring pigment can give the pearlescent eye shadow paint an orange-yellow color. When compounded with synthetic fluorphlogopite, calcium aluminum borosilicate and titanium dioxide, an orange-yellow elastic pearlescent eye shadow paint with shining luster, blurring effect and light protection effect can be obtained.

[0053] Of course, it is understandable that the red iron oxide, i.e. ferric oxide, as the coloring pigment can also be replaced by one or a combination of yellow iron oxide, black iron oxide, ultramarine, chromium oxide green, manganese violet, and carmine to give the elastic pearlescent eyeshadow paint the desired color.

[0054] In some embodiments, the glass pearlescent mixture is composed of calcium aluminum borosilicate, titanium dioxide and tin oxide, and the CAS numbers of the three components are: 65997-17-3, 13463-67-7, 18282-10-5. In one embodiment, the glass pearlescent mixture is composed of calcium aluminum borosilicate, titanium dioxide and tin oxide in a mass ratio of 96.4:3.5:0.1. Exemplarily, the glass pearlescent mixture can be purchased from Fujian Kuncai Material Technology Co., Ltd., with the trade name: COSMI 9810B Special FlashDiamond White.

[0055] In the elastic pearlescent eyeshadow paint of the present application, the oil component comprises polyisobutylene and an oil mixture.

[0056] In some embodiments, the mass ratio of polyisobutylene to the oil mixture is 1:(8-15).

[0057] In the embodiments of the present application, the oil component is limited, and the mass ratio of polyisobutylene and the oil mixture is 1: (8-15), so that when the oil component is composed of polyisobutylene and the oil mixture, the performance of the elastic pearlescent eye shadow paint obtained at this time is better. When the polyisobutylene component is too much, it will cause the adhesion of the eye shadow to be too high, produce a greasy feeling, weaken the ductility, and also cause difficulties in the processing of the eye shadow. Therefore, the polyisobutylene component should not be too much. When the polyisobutylene component is too little, it may cause the eye shadow to have insufficient emollient and adhesion after use, and in severe cases, flying powder and slag may occur. Therefore, it is more appropriate to control the mass ratio of polyisobutylene and the oil mixture to 1: (8-15). Exemplarily, the mass ratio of polyisobutylene and the oil mixture is 1: 8, 1: 9, 1: 10, 1: 15, 1: 12, 1: 13, 1: 14, 1: 15.

[0058] In some embodiments of the present application, when the mass ratio of polyisobutylene to the oil mixture is controlled at 1:(8-12), the obtained elastic pearlescent eyeshadow paint has the best performance.

[0059] In some embodiments, the grease mixture is a mixture of polydimethylsiloxane / polydimethylsiloxane cross-linked polymer and isononyl isononanoate. Polydimethylsiloxane cross-linked polymer is composed of polydimethylsiloxane and silane polymer, and can form a network structure by connecting PDMS units through silane. Both polydimethylsiloxane and polydimethylsiloxane cross-linked polymer can be abbreviated as PDMS.

[0060] In some embodiments of the present application, the grease mixture is a mixture of dimethicone / dimethicone cross-linked polymer and isononyl isononanoate in a mass ratio of 1:(1-2). Exemplarily, the mass ratio of dimethicone / dimethicone cross-linked polymer and isononyl isononanoate is 1:1.1, 1:1.15, 1:1.2, 1:1.25, 1:1.28, 1:1.3, 1:1.5, 1:1.6, 1:1.8, 1:1.9.

[0061] In one embodiment of the present application, the oil mixture is a mixture of polydimethylsiloxane, polydimethylsiloxane crosspolymer and isononyl isononanoate in a mass ratio of 3:1:5.

[0062] In the embodiments of the present application, polydimethylsiloxane / polydimethylsiloxane cross-linked polymer is a mixture of fixed proportions, and the CAS number is: 63148-62-9. Polydimethylsiloxane / polydimethylsiloxane cross-linked polymer is a gel-like mixture obtained by diluting polydimethylsiloxane cross-linked polymer with polydimethylsiloxane. At least polydimethylsiloxane / polydimethylsiloxane cross-linked polymer with the brand number of BT-9081 of Guangzhou Bataixing Material Technology Co., Ltd. can be selected.

[0063] In the embodiment of the present application, isononyl isononanoate, whose CAS number is: 59219-71-5, can be selected from at least DUBININA and STEARINERIE DUBOIS FILS.

[0064] In some embodiments of the present application, polyisobutylene, whose CAS number is 9003-27-4, can be at least a product purchased from DL Chemiical Co. Ltd with a trade name of PB950.

[0065] In order to better combine and stabilize the several powder components in the eye shadow, the present application has compounded the type and amount of the oil component. The polydimethylsiloxane cross-linked polymer in the oil component is a silicone elastomer with a network structure, which can provide elasticity and structural support, so that the powder component can be bonded to the silicone elastomer of the polydimethylsiloxane cross-linked polymer network structure while retaining the powder component in the network structure, preventing the powder component from easily falling off and causing flying powder or even falling off. The elasticity of the polydimethylsiloxane cross-linked polymer is compounded with polydimethylsiloxane, isononyl isononanoate and polyisobutylene, and the oily component is used to bond the powder component, so that it has a certain viscosity but is not sticky. At the same time, the elasticity and structural support of the network structure make it not easy to fly powder and fall off when it is under stress, for example, it is not easy for the user to fly powder and fall off when in motion or in a scene blown by the wind. It also keeps the powder component that gives the elastic pearlescent eye shadow paint its color in the network structure, and compounding with the pearlescent powder makes the elastic pearlescent eye shadow paint have good colorability.

[0066] Polyisobutylene (PIB) in the oil component is a synthetic high-molecular compound with high viscosity. It has a similar structure to the straight-chain alkanes in sebum and has good compatibility with the skin. It can not only form a protective film on the skin surface to prevent skin moisture loss, but also facilitate the application and spread of cosmetics on the skin. At the same time, compounding with the oil mixture can also enhance the stability and binding degree of the powder component.

[0067] In addition, the isononyl isononanoate in the oil component has a unique multi-methyl branched structure, good dispersibility to colorants, soft and refreshing touch without greasy feeling, and is an excellent stabilizer and emollient. Polyisobutylene has a certain viscosity and thickening effect, elastic silicone elastomer gel can provide elasticity and structural support, and isononyl isononanoate has good lubrication and dispersibility, and these three ingredients have a certain compatibility in chemical properties and physical properties. The combination of these three can produce a synergistic effect, complement each other and enhance their respective performance, thereby making the entire system more stable. In addition, polydimethylsiloxane can be added to the oil component. This oil component has little irritation to the skin, a low risk factor, is relatively safe, can be used with confidence, generally has no effect on pregnant women, and is not acne-causing. It is understandable that those skilled in the art can also add other oily substances on the above basis, and the resulting product is still within the scope of protection of this application.

[0068] In some embodiments of the present application, the elastic pearlescent eye shadow paint further includes: an additive, wherein the additive includes one or more of an antioxidant and a preservative.

[0069] In some embodiments, the additive accounts for 0.3wt.% to 1.8wt.% of the sum of the mass of the powder component and the oil component. The additive is mainly an antioxidant, and the preservative ensures that the elastic pearlescent eyeshadow paint does not become rancid. Exemplarily, the additive accounts for 0.1wt.%, 0.2wt.%, 0.25wt.%, 0.3wt.%, 0.45wt.%, 0.5wt.%, 0.6wt.%, 0.7wt.%, 0.75wt.%, 0.8wt.%, 0.90wt.%, 1.0wt.%, 1.1wt.%, 1.2wt.%, 1.4wt.%, 1.5wt.%, 1.6wt.%, 1.75wt.% of the sum of the mass of the powder component and the oil component.

[0070] In some embodiments of the present application, the elastic pearlescent eye shadow paint also includes antioxidants and preservatives. Since one of the main components of eye shadow is the oil component, it is prone to oxidation and rancidity, resulting in the deterioration of the eye shadow, so antioxidants can be added to the eye shadow.

[0071] In some embodiments of the present application, the antioxidant includes one or more of tocopherol, tocopherol acetate, gallic acid, methyl gallate, ethyl gallate, and propyl gallate.

[0072] In one example, tocopherol acetate can be added as an antioxidant. Tocopherol acetate has a low risk factor and a good antioxidant effect.

[0073] In some embodiments of the present application, the preservative includes one or more of phenoxyethanol, caprylyl glycol, and ethylhexylglycerin. The function of the preservative is mainly to inhibit the growth of microorganisms in the eye shadow and extend the shelf life of the eye shadow. In some examples, phenoxyethanol, caprylyl glycol, and ethylhexylglycerin can be used as preservatives. Using a variety of different preservatives, better preservative effects can be achieved through different antibacterial pathways, and phenoxyethanol, caprylyl glycol, and ethylhexylglycerin have low risk factors, low toxicity, and no allergic irritation.

[0074] In a second aspect, the present application provides a method for preparing an elastic pearlescent eyeshadow paint, such as Figure 3 As shown, the preparation method of the elastic pearlescent eyeshadow paint comprises:

[0075] S1. Dispersing the filling powder and the pearlescent powder according to the proportion of the elastic pearlescent eyeshadow paint to obtain a powder component;

[0076] S2, dispersing polydimethylsiloxane / polydimethylsiloxane cross-linked polymer and isononyl isononanoate to obtain a grease mixture;

[0077] S3, dispersing the oil mixture and polyisobutylene to obtain an oil component;

[0078] S4, dispersing and shaping the powder component, the oil component and / or the additive to obtain the elastic pearlescent eyeshadow paint.

[0079] The preparation method of the elastic pearlescent eyeshadow paint in the embodiment of the present application is relatively simple, does not require the use of complex processes and instruments, can be prepared by simple mixing and dispersion, has low production costs, and is suitable for large-scale industrial production. At the same time, since the powder component content in the elastic pearlescent eyeshadow paint is relatively high, after each component is evenly dispersed, the elastic pearlescent eyeshadow paint product with the desired design shape can be prepared by shaping, which is easy to carry.

[0080] In the method for preparing the elastic pearlescent eyeshadow paint of the embodiment of the present application, the step of preparing the powder component includes: stirring the filling component and the pearlescent component at 3000 r / min to 5000 r / min for 10 seconds to 30 seconds.

[0081] In the step of preparing the oil mixture in the preparation method of the elastic pearlescent eyeshadow paint in the embodiment of the present application, the process parameters that need to be met for mixing and dispersing the polydimethylsiloxane / polydimethylsiloxane cross-linked polymer and isononyl isononanoate are: stirring at 1000r / min~4000r / min for 10 seconds~30 seconds.

[0082] In the step of preparing the oil component in the preparation method of the elastic pearlescent eyeshadow paint in the embodiment of the present application, the process parameters that need to be met for mixing and dispersing the oil mixture and polyisobutylene are: stirring at 3000r / min~5000r / min for 10 seconds to 30 seconds.

[0111] Table 3

[0112]

[0113]

[0114] From the test results in Table 3, it can be seen that the subjects did not have any adverse reactions to the elastic pearlescent eyeshadow paints prepared in the embodiments and comparative examples, which shows that the raw materials used in this application have a low risk factor, and the provided products are safe and non-irritating and suitable for most consumers.

[0115] 2. Public opinion survey test: A public opinion survey method was adopted, and 30 female volunteers aged 20 to 40 were selected to try out various embodiments and comparative examples, and the coloring effect, ductility, and degree of powder flying and slag falling were evaluated. 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. The scoring results are shown in Table 4 below.

[0116] Table 4

[0117]

[0118]

[0119] From the test results in Table 4, we can see that:

[0120] In the elastic pearlescent eyeshadow paint prepared in Comparative Example 1, due to the low content of polyisobutylene, although the ductility is good, the colorability is poor, and it is very easy to fly powder and fall off. In the elastic pearlescent eyeshadow paint prepared in Comparative Example 2, the polyisobutylene content is too high, although it is not easy to fly powder and fall off, the colorability is relatively poor, and the ductility is very poor. In the elastic pearlescent eyeshadow paint prepared in Comparative Example 3, due to the absence of polyisobutylene, the colorability and ductility are poor, and the powder flying and falling off are serious after use.

[0121] The elastic pearlescent eyeshadow paint prepared in Example 1 has good colorability, ductility and is not easy to fly powder and slag. Compared with the elastic pearlescent eyeshadow paint of Example 1, the elastic pearlescent eyeshadow paint prepared in Example 2 has a higher content of filling components in the powder component, and its ductility and flying powder and slag performance are slightly weaker. Although the colorability is poor, it is still higher than the colorability of the elastic pearlescent eyeshadow paint of Comparative Examples 1-3. Compared with the elastic pearlescent eyeshadow paint of Example 1, the elastic pearlescent eyeshadow paint prepared in Example 3 has a lower content of isononyl isononanoate, although the colorability is better, the ductility is relatively poor. Compared with the elastic pearlescent eyeshadow paint of Example 1, the elastic pearlescent eyeshadow paint prepared in Example 4 has a lower content of polyisobutylene, although the ductility is better, the colorability is poor, and it is easy to fly powder and slag. In the elastic pearlescent eyeshadow paint prepared in Example 5, due to the higher content of polyisobutylene, although it is not easy to fly powder and slag, the ductility is poor.

[0122] The above test results show that only by controlling the ratio between the powder component and the oil component in the elastic pearlescent eyeshadow paint within the range specified in this application and by controlling the specific type of the oil component can an elastic pearlescent eyeshadow paint with no flying powder, good colorability and good ductility be obtained.
